Deeds of outstanding members of the middle level of the Highway Bureau
Male, born in November 1970, member of the Communist Party of China, university degree, engineer, current chief of the road branch. Since joining the work in August 1991, he has been engaged in the reconstruction and maintenance management of highway and bridge projects. In the course of work, we must earnestly study the party's line, principles, and policies, implement the scientific development concept, work hard to implement the important ideas of the three representatives, update concepts, keep pace with the development of the times, be dedicated, honest, trustworthy, hardworking, and diligent. jobs. He often goes deep into the construction of the first line, listens to the opinions of the workers humbly, actively puts forward reasonable suggestions, strives to carry out technological innovations, and invests less in engineering, high quality, and good efficiency, and finds ways. Actively participate in continuing education, accumulated a wealth of professional theoretical knowledge, theory and practice, and constantly improve their ideological and professional standards.
In the 19-year road work, he became a real road man. His sweat was almost spread over the roads in his jurisdiction. His understanding and understanding of the branch management roads was like children’s loved ones. Understand the same, do not turn records, do not need to check the information, as long as it is on the road, even if it is a milestone, where is the 100-meter pile, he can sing along with the mouth, such as a few Jane. As a result of many maintenance work points, wide areas, long lines, and thousands of threads, as a manager of the work, he is always afraid of any mistakes, always be cautious. Every report and every drawing should be personally examined and analyzed. Each group of materials must be checked personally. Every construction program and every construction safety sign must be personally questioned. The materials to be entered must be checked in person. I’m too busy to work overtime. It’s not uncommon to work overtime, but he doesn’t have a complaint and still works forgotten. He often said to his colleagues: The superior leader gave me the maintenance work, which is a great trust to me. I have no reason to do it well. Besides, I am a party member and I must be worthy of the title of party member. With his own tangible actions, he set an example for his employees and was deeply embraced and loved by his staff. For more than ten years, he has consistently maintained a dedication to work, meticulous work style, dedicated all his energy to the road maintenance business, and has been rated as advanced by the provincial and municipal highway departments. Producer.
First, courageous in scientific research and innovation, strict operation and standardization, and paying great attention to the quality of engineering in construction. He conscientiously implements the four-level quality assurance system, improves the construction procedures, quality acceptance procedures, and strengthens the construction process control. Under the premise of ensuring quality and safety, Comprehensively speed up the progress of the project, effectively improve the project management level, and ensure that the reconstruction and maintenance of large and medium-sized repair projects are completed on time, with high quality and efficiency.
In 1995, he participated in the reconstruction of the satellite bridge on the Provincial Highway 102. He established a sense of quality engineering, standardized construction management, from construction preparation, measurement and stakeout, to the upper and lower structures and other processes, layer by layer, in accordance with construction specifications, painstaking research, in-depth exploration, bold use of new materials, new technology, full Bring in the wisdom of the team and successfully complete the task. Bridgehead jumping is one of the common diseases on the road. It is often caused by the backfilling of the back of the platform. To this end, during the construction, the backfilling of the abutment back was especially strengthened, and a number of technical measures were taken to ensure the quality of the backfilling of the back of the platform. After the bridge was opened for many years, the bridgehead did not produce a jump phenomenon. The quality of the bridge reconstruction project was excellent, and it was commended by the superiors. It won the honor for the unit and brought considerable economic benefits.
In 1997, he participated in the construction of the 15km reconstruction project in the eastern section of the Provincial Highway 307, and served as the technical leader of the project. As a semi-rigid material, lime-gravel is known for its excellent mechanical strength, superior fatigue resistance and excellent water stability. It was widely used in the base layer of high-grade roads. However, it is prone to the inherent weakness of structural cracks, which is exacerbated by the poor gradation of suspended mixtures, which is often confusing. He and the technical backbone used the Beray method to analyze the rationality of the aggregate composition of the aggregate, carefully optimize the proportioning composition of the lime-ash gravel mixture, and focus on improving the construction technology. According to the relevant norms, standards and test results, the test section is paved, and the repeated demonstration is carried out to control the optimal ratio of aggregate and ash content. The paved ash and gravel base layer not only has excellent crack resistance and erosion resistance, but also Since the mixture has good uniformity, it exhibits good effects in preventing segregation of the mixture, ensuring durability and stability of the structure. The construction experience of this process has been extended to the construction of highway engineering in the city.
From May 1998 to June 1999, he participated in the construction of the 10.5 km reconstruction of the Jieshang Expressway connecting line. In the subgrade construction, Wang Renji has a large section of low-lying reservoir area in Nantou. The groundwater level is high, and the groundwater level of some sections enters the subgrade working area. After the topsoil is removed, it is crushed by a compacting machine, and the state of the spring is exhibited. After repeated rolling, it is still impossible to form, and the compaction degree required by the specification cannot be achieved. In view of the special subgrade situation, after analyzing the cause of the disease, after research, he believed that the purpose of the treatment was to reduce the water content and groundwater level of the surface water, reduce the plasticity of the soil and cut off the passage of capillary water. Therefore, it was decided to adopt the following schemes for comprehensive treatment: excavation of drainage ditch draining surface water and lowering of groundwater level. According to repeated trials on site, it is determined that the moisture content of the soil layer during tillage is preferably controlled within 28%, so as to avoid the soil being too wet to form a mass and not easily broken. The water content of the backfill after drying is in accordance with the optimum water content and then compacted. 2. Add lime. The dosage of lime added is 4%-6% according to the test. The effect is to absorb water and evaporate. The lime digestion can absorb the moisture of the soil, release the heat to promote the evaporation of water, and shorten the drying time of the backfill. The second is to strengthen the water barrier. 3, seepage drainage. The main function of the seepage is to intercept the groundwater level that flows to the roadbed and discharge the water out of the affected area. 4. Isolation of surface water. In order to prevent surface water from seeping into the subgrade soil during the rainy season, the roadbed slope adopts a 0.5m thick clay slope, and the bottom of the roadway is covered with a strong-strength geotextile and made into a 4% bidirectional cross slope to ensure the pavement structure layer. The water has a drainage outlet. The above-mentioned various methods are used to comprehensively control the over-wet soil roadbed, and the treatment scheme is simple and the construction cost is not high. It not only solves the problem of subgrade construction in low-lying areas, but also eliminates many hidden dangers caused by the normal use of highways in the future.
From March to June, he presided over the construction of the 02 section of the Chulifeng Reconstruction Project and served as the project manager. During the review of the construction drawings, it was found that due to the negligence of the original design, the design elevations at both ends of the Jiangji Railway level crossing were not closed, and the difference was 45 cm. In addition, the south section of the railway crossing crosses the residential area, because the demolition is not timely, and the flat curve changes in many directions, resulting in no connection between the construction design drawings. He led the technical staff of the project department to conduct on-the-spot investigation and design, and draw a practical construction drawing according to the site environment, technical specifications and design standards, and was approved by the supervision, design unit and owner for construction and received favorable comments.
Entering the new century, with the rapid and coordinated development of the national economy, the road traffic volume is increasing, especially in recent years, the vehicles are rapidly becoming large and severely over-limit, which makes the road surface face a severe test. In particular, the road is eroded by rainwater, and the s305 and s202 cement pavements are cracked, broken, muddy, staggered, and the expansion joints are crushed, and the slippage of the plates is aggravated; the s308 line and the Lichu road asphalt pavement also have large-area pits. Diseases such as subsidence, looseness, and cracking pose great challenges to maintenance management. Faced with this grim situation, he carefully clarified his ideas, focused on the long-term, made overall considerations, mobilized employees, and worked together to lay the groundwork for disease treatment.
In order to understand the actual situation of the road in a timely and dynamic manner, he organized relevant personnel to conduct road condition investigations, and at the same time, conducted special investigations and special inspections on the changes of road conditions from time to time. On the basis of comprehensive grasp of the road conditions and careful analysis of the survey data, formulate practical maintenance plans and construction plans. In accordance with the principle of prevention and prevention combined, timely organize the construction force to rush to repair the heavily damaged sections of the cement pavement, timely repair the pits and subsidences of the asphalt pavement, select the sections to cover the surface, curb the decline of the road conditions, and ensure the normal traffic of the vehicles.
In the construction of maintenance projects, it has overcome the difficulties of relatively lack of technical strength, backward aging of mechanical equipment, inefficiency, and insufficient quantity, and seized the fine weather to speed up the construction progress. Standardize construction management, strengthen quality awareness, resolutely put an end to the bad tofu project after the repair, strictly enforce the quality is not good, reinvent the burden, lose the burden, and strictly check the quality policy to ensure the quality of the maintenance project. The quality of the dry projects is high, the progress is fast, and the benefits are good, which has been fully affirmed by the higher authorities.
Second, the refined management, to create a "smooth, clean, green, beautiful, safe" road traffic environment after the competition, become the head of the road branch, the face of the transformation of roles, new jobs, different management requirements, he Feel a bit of pressure.
With the rapid development of the socialist market economy, various drawbacks of the original management methods and operational mechanisms have become increasingly apparent. First, there is no distinction between enterprises and enterprises. The big pot rice, the iron rice bowl, the high input and the low output are very serious. Second, people are overstaffed and have low benefits. It is common for workers to work or not to work, and production efficiency is low.
In response to this situation, how to make the road industry out of the predicament, re-energize the vitality, the branch leaders realize that early change and early initiative, late change is passive, only reform is the only way out. As a result, the reform of the maintenance operation mechanism was fully rolled out in the branch office.
As the chief of the industry, the responsibility is on the shoulders. He has his own unique opinions and strategies for the management of maintenance workshops and roads. He first established the system of establishment, so that the staff work has standards, positions are responsible, behaviors are standardized, everything has rules to follow, and people are controlled by others. Institutional management. Then, with the strong support of the leaders of the branch office, in view of the drawbacks of the original road maintenance management system and operation mechanism, and the existence of maintenance funds to support people, he boldly reformed and innovated constantly, and vigorously promoted fixed maintenance and maintenance payment in maintenance production. The system, the use of posts to fund, the implementation of performance-linked, rewards and lazy, opened the wage income of employees, greatly stimulated the enthusiasm and enthusiasm of the frontline maintenance workers. Because he grasped a fine word in his work, he grasped a strict word in management and grasped a slogan in the implementation, which strengthened the employees' sense of urgency, competition and responsibility, changed their attendance and did not work, and did more work. Effectively ensure the smooth development of all work.
Through reforms, the hurricane has been swayed, and the spirit of the road has been renewed. The mental outlook of the road workers has taken on a new look. The quality of road maintenance has been improved year after year, and the benefits of road maintenance funds have been fully utilized. The road conditions of the 217.8km roads managed are steadily increasing, and the good road rate is increasing by about 1.8% every year. The domestic trunk roads have basically achieved the goals of smooth, clean, green, beautiful and safe. The road construction basically meets the requirements of more, faster, better and cheaper. In the short period of the fifteenth period, the sub-bureau added and rebuilt the highway 96 kilometers, and completed the provincial roads 305, 202, 308, and the county roads 045, 034, 054. The line and the whole village propulsion oil road project have more than 150 kilometers of large and medium-sized repair projects, and the excellent rate of the project has reached more than 80%. Reduce maintenance costs, improve the quality of maintenance, enhance the management efficiency of the industry, and promote the sustained, healthy and rapid development of the highway industry. Achieved high-quality, zero accidents, built a number of projects, trained a team, and cultivated a group of talents.
In the years of conservation work, due to his creative work, he has accumulated some good practices, mainly in the following aspects:
1. Strengthen daily maintenance, eliminate all kinds of diseases in time, and ensure the smooth flow.
Adhere to the principle of continuous, fast and efficient, and strive to ensure that the road surface is clean and consistent, the road damage is repaired in a timely and rapid manner, and the daily maintenance of the ancillary facilities is persevering. The road shoulder repair, bridge and culvert maintenance and side trench cleaning are often unremitting. Adhere to the combination of custody, preventive maintenance and assault maintenance, and comprehensively improve the road rate.
(1) Daily maintenance of road shoulders and roadbeds. Stick to four holds. That is to keep the shoulders smooth and clean, the edges are straight, no tall grass, no debris accumulation; second, to keep the roadbed slope stable, smooth and no gully; three to maintain the drainage system such as side ditch, drainage ditch, no siltation, The water flow is smooth, the inlet and outlet are kept good; the fourth is to keep the protective structure intact, the expansion joint of the retaining wall is good, and the drain pipe is unblocked.
(2) In the daily maintenance work of the road surface, it is required to be accurate, precise, fast and diligent. It is meant that the maintenance personnel of the road can adhere to the maintenance inspection and accurately judge the type of road damage; the fine refers to the ability to analyze and find out the cause of the disease, and can formulate a practical treatment plan and adopt correct technical treatment measures; Damage repair is timely, effective and quick to regulate; diligence refers to cleaning, work and cleaning in the maintenance work, and always keep the road surface level, the road capacity is clean and the drainage is good.
(3) Strengthen the daily maintenance of bridges and culverts. Adhere to regular inspections, regular inspections and inspections, systematically grasp the state of bridge technology, and propose maintenance measures. Defects, damages, and timely repairs found in inspections, ensure vehicle safety, and extend the service life of bridges and culverts.
(4) Daily maintenance of facilities along the line. Regular inspections to check whether the various signs are obstructed and damaged by trees, billboards, and temporary and special inspections of the integrity of the signs, safety positions, angles, paints, reflective materials, pedestals, etc., and timely implementation plans for restitution. In the case of defects, skews, high and low inconsistencies, timely replacement, replenishment, repair, cleaning of paint, and strengthening maintenance, so that they are always kept neat, in good, and eye-catching.
2, highlight the key points, take points to face, do a good job of small repair preventive maintenance, and constantly improve the road appearance.
In recent years, with the implementation of tax and fee reform, the secondary roads have been withdrawn, the traffic volume has increased, and the number of overloaded vehicles has increased dramatically, which has made the roads overwhelmed; especially in the late winter and early spring, the rain and snow weather has been frequent, which has accelerated the damage of the road surface. The road surface of the maintenance road has serious diseases, the road conditions have declined rapidly, the road traffic capacity and the service level of the road network have been significantly reduced, and the maintenance situation is very serious. He is fully aware of the importance and necessity of spring road maintenance and regards road stability as a top priority. In accordance with the maintenance plan, combined with the actual conditions of the road, vigorously strengthen the preventive maintenance of minor repairs and take effective measures to treat the asphalt pavement diseases. At the same time, the combination of regular joints and periodic caulking, careful maintenance of cement pavement joints to ensure water sealing. The strip type asphalt sealing method is used to treat medium and mild cracks on the cement concrete pavement, and the road condition is restored as soon as possible. We will make early plans, implement them early, highlight key points, and take care of both the symptoms and the symptoms, ensuring the safe and smooth flow of key maintenance sections.
3. Actively carry out labor competition activities and promote the overall improvement of road management quality.
In the maintenance management, he always used the good road cup labor competition as a means to promote maintenance management and mobilize the enthusiasm of employees. Each year, in each maintenance team and each class, labor competitions and maintenance management activities such as road-shouldering, standard repairing road pits, broken corners, and pits are carried out. Through the development of the activities, summing up and promoting the experience, promoting the maintenance of the competition, and comprehensively improving the overall quality of the employees; through the development of competition activities, educating the employees to work hard and dedication, make efforts to complete various production tasks, and effectively promote the road The overall quality of management is improved.
4. Constantly improve and standardize the internal materials, and earnestly grasp the work of intercourse.
(1) Raise awareness, strengthen leadership, and regularly train cadres and intermediaries to ensure that they are more proficient in the compilation and archiving of internal data.
(2) According to the unified requirements of the municipal bureau, fill in the wall chart and other various checklists, and organize and archive in time to ensure that the internal information is accurately, standardized, complete and timely.
(3) Strictly manage the transfer and take necessary measures to ensure that the survey data is accurate and true. Because the traffic observation stations are scattered and the work is monotonous, if the transfer personnel do not have a strong sense of responsibility, the correctness of the information will not be guaranteed. To this end, he led the staff of the department to strengthen the spot check on the observation day, regularly arrange the management personnel to conduct random checks and assessments, report the quality of observations on time, eliminate the unauthorized removal of posts, leave the post, and fabricate data phenomena. Transfer information for road construction services.
5, the safety of production alarms often sound, comprehensive management is often unremitting.
Road maintenance operations have many points, long lines and wide areas, which pose new challenges for construction safety work. Therefore, safety production must be prevented from being prior to the organization, from the organizational guarantee, from the institutional improvement, and from the measures. Every year, he purchases mesh safety clothing and protective safety clothing for employees, and purchases reflective construction signs and cones for work areas and roads, and has produced safety warning signs. Every effort is made to create a safe, efficient, civilized and orderly environment for maintenance operations. Everyone in the branch office speaks about safety, and the atmosphere of prevention is formed everywhere, thus minimizing accidents and preventing major personal injury and death.
6. Concentrate on strength, focus on the overall situation, and strive to do a good job in inspections.
According to the deployment of the provincial bureau and the municipal bureau, we will conscientiously implement the inspection plan for the Ministry of Communications, concentrate our efforts, focus on the overall situation, work hard, and take good road conditions, road appearance and standardized management to meet the national highway inspection and fully display the highway. New image.
It is precisely because he is working hard to promote the new concept of life cycle maintenance, refined maintenance, comprehensive maintenance, comprehensive implementation of maintenance quality requirements, and effectively improve the quality of highway traffic. Therefore, the attendance rate of the staff of the points bureau is high, the maintenance of the standard section is in place, the daily maintenance work is solid; the preventive maintenance of minor repairs is timely and standardized; the quality of the large and medium-sized repair projects is high, the progress is fast, and the benefits are good, which is highly praised by the superiors. - For three consecutive years of evaluation, the branch maintenance work is in the forefront of the city.
Third, the brave and heavy guarantees are unimpeded, and all the people are fighting against the disaster
At the beginning of July, heavy rains in the Huaihe River Basin have caused serious floods in most areas, and the lives and property of the people are seriously threatened. The roads managed by the branch were also washed and swallowed by the raging flood. Many sections of s308 and s224 have been flooded with water, and the road surface has been damaged. Road shoulders and slopes have been washed away, and soil erosion is serious. Bridge and culvert structures have suffered different degrees of water damage, scouring, rupture and collapse.
Lyricism is the command, and responsibility is more important than Mount Tai. In the face of sudden natural disasters, the branch strengthened the organization and leadership, so that the minds were recognized, the work measures were in place, and the work of flood prevention and rescue was done. The broad masses of cadres and workers have taken care of the overall situation, and they have learned the general spirit, carried forward the spirit of not being afraid of danger, and upholding the difficulties, and all the efforts to resist the flood, and go all out to ensure smooth flow. On July 2nd, the area of the s308 line k108+030 Zhigou Bridge section was 90 cm deep, and dozens of vans were blocked. When I saw this situation, I felt that there was a sense of dereliction of duty, so he urgently adjusted the forklift while topping When the rain stood in the water as a road sign, the vehicles were allowed to pass by, and the station was a few hours in the water. The feet were white, and the next day, a high fever was started. On July 12, the river dam broke the s224 line k6+. The subgrade of the Beibeigou Bridge section was washed away by the flood. He saw the head and jumped into the water. Everyone advised him not to fight hard. He insisted firmly: As the section chief, my position is in the first line, I don’t go into the water, I am in the water, I Who is not risky? ... In the floods of the day and night, he was rushing in the rain, wading through the mud, did not sleep a sense of stability, did not eat a normal meal, when the passing drivers and pedestrians looked at his bloodshot eyes and When you are tired and muddy, you will cast an admirable look. The crops of the relatives and friends of the old family were flooded, and the house was flooded and collapsed. He couldn’t take it back and look at it; the mother was seriously ill and he could not wait in front of the bed. Instead, she is a small family, and everyone is devoted to the flood fighting and rescue work. Still lead the staff to piling, damming, sandbags, blocking the gap, setting signs, diverting traffic, and guarding against the stagnation, ensuring the safety of highway bridges. In the days of disaster relief, the roads managed by the branch offices played a lifeline role in ensuring the material supply in the disaster areas. The employees used their actual actions to compose a strong song of dedication and no regrets, highlighting the special ability of highway people. Hard work, especially fighting spirit.
At the beginning of the Spring Festival, a rare, continuous, large-scale low-temperature blizzard and freezing disaster swept through the provinces and cities in the middle and lower reaches of the Yangtze River. The rainy and snowy weather of the past day broke the originally tight and orderly daily maintenance balance, which had a huge impact on road transport, especially the snow on January 27 was aggravated by the highway traffic. Due to the volley of the bridge, the bridge surface is particularly prone to snow accumulation and is difficult to melt. As the chief of the industry, the rescue was his first reaction in bad weather and unexpected events. He looked at the snow and found that the snow was very serious, such as the Cihuaixin River Bridge, the Madian Bridge, and the s308 Highway Overpass. The centimeter thick is a serious threat to traffic safety.
Snow is a silent order, the branch immediately launched an emergency plan for anti-ice and snow disasters, and organized a professional team to carry out snow removal work. He led the commandos to work overtime to spread salt, sand, grass bags, snow removal, ice shovel, clearing the barriers, melting snow at the fastest speed, freezing, slipping, troubleshooting, and fighting for disasters. Although the weather was very cold, the commandos did everyone sweating, the heat rose, and some took off the cotton... After three consecutive days of fighting, the snow in the main driveway of the road was completely cleared, and the road was guaranteed. The bridge is safe and smooth.
In the face of the 50-year-old snow test, and his colleagues are united in the city, fought and attacked, heroic and good warfare, with high fighting enthusiasm, melted the dangers of ice and snow, and reduced the damage caused by the catastrophic ice and snow weather to a minimum. The cold wind is biting, and the ice is lying on the ice. It is the frankness of the roads they maintain; the shovel is wielding, and it is hard and hard, they guarantee the smooth flow of traffic. When the snow and ice came, they practiced the road to ensure the smooth flow of the road in the snow and ice, and used the flesh and blood to set off the bridge of safe traffic and harmonious traffic, and wrote a magnificent song with the passion of selfless dedication. Music.
The language is simple and hardworking, and he is a diligent and hardworking person. He is diligent and diligent, doing things in a down-to-earth manner, and is willing to make a road stone. He is willing to be a scorpion cow, with his wisdom, high work enthusiasm and sincerity and perseverance in his career. I work quietly and pay for the cause of conservation. There is no such thing as a thousand miles, and there is no way to build a river. It is this bit by bit that embodies the true meaning of his sincere love and selfless dedication.
In the 19-year road work, he became a real road man. His sweat was almost spread over the roads in his jurisdiction. His understanding and understanding of the branch management roads was like children’s loved ones. Understand the same, do not turn records, do not need to check the information, as long as it is on the road, even if it is a milestone, where is the 100-meter pile, he can sing along with the mouth, such as a few Jane. As a result of many maintenance work points, wide areas, long lines, and thousands of threads, as a manager of the work, he is always afraid of any mistakes, always be cautious. Every report and every drawing should be personally examined and analyzed. Each group of materials must be checked personally. Every construction program and every construction safety sign must be personally questioned. The materials to be entered must be checked in person. I’m too busy to work overtime. It’s not uncommon to work overtime, but he doesn’t have a complaint and still works forgotten. He often said to his colleagues: The superior leader gave me the maintenance work, which is a great trust to me. I have no reason to do it well. Besides, I am a party member and I must be worthy of the title of party member. With his own tangible actions, he set an example for his employees and was deeply embraced and loved by his staff. For more than ten years, he has consistently maintained a dedication to work, meticulous work style, dedicated all his energy to the road maintenance business, and has been rated as advanced by the provincial and municipal highway departments.

Standardize construction management, strengthen quality awareness, resolutely put an end to the bad tofu project after the repair, strictly enforce the quality is not good, reinvent the burden, lose the burden, and strictly check the quality policy to ensure the quality of the maintenance project. The quality of the dry projects is high, the progress is fast, and the benefits are good, which has been fully affirmed by the higher authorities.
Second, the refined management, to create a "smooth, clean, green, beautiful, safe" road traffic environment after the competition, become the head of the road branch, the face of the transformation of roles, new jobs, different management requirements, he Feel a bit of pressure.
With the rapid development of the socialist market economy, various drawbacks of the original management methods and operational mechanisms have become increasingly apparent. First, there is no distinction between enterprises and enterprises. The big pot rice, the iron rice bowl, the high input and the low output are very serious. Second, people are overstaffed and have low benefits. It is common for workers to work or not to work, and production efficiency is low.
In response to this situation, how to make the road industry out of the predicament, re-energize the vitality, the branch leaders realize that early change and early initiative, late change is passive, only reform is the only way out. As a result, the reform of the maintenance operation mechanism was fully rolled out in the branch office.

Effectively ensure the smooth development of all work.
Through reforms, the hurricane has been swayed, and the spirit of the road has been renewed. The mental outlook of the road workers has taken on a new look. The quality of road maintenance has been improved year after year, and the benefits of road maintenance funds have been fully utilized. The road conditions of the 217.8km roads managed are steadily increasing, and the good road rate is increasing by about 1.8% every year. The domestic trunk roads have basically achieved the goals of smooth, clean, green, beautiful and safe. The road construction basically meets the requirements of more, faster, better and cheaper. In the short period of the fifteenth period, the sub-bureau added and rebuilt the highway 96 kilometers, and completed the provincial roads 305, 202, 308, and the county roads 045, 034, 054. The line and the whole village propulsion oil road project have more than 150 kilometers of large and medium-sized repair projects, and the excellent rate of the project has reached more than 80%.

The roads managed by the branch were also washed and swallowed by the raging flood. Many sections of s308 and s224 have been flooded with water, and the road surface has been damaged. Road shoulders and slopes have been washed away, and soil erosion is serious. Bridge and culvert structures have suffered different degrees of water damage, scouring, rupture and collapse.
Lyricism is the command, and responsibility is more important than Mount Tai. In the face of sudden natural disasters, the branch strengthened the organization and leadership, so that the minds were recognized, the work measures were in place, and the work of flood prevention and rescue was done. The broad masses of cadres and workers have taken care of the overall situation, and they have learned the general spirit, carried forward the spirit of not being afraid of danger, and upholding the difficulties, and all the efforts to resist the flood, and go all out to ensure smooth flow. On July 2nd, the area of the s308 line k108+030 Zhigou Bridge section was 90 cm deep, and dozens of vans were blocked. When I saw this situation, I felt that there was a sense of dereliction of duty, so he urgently adjusted the forklift while topping When the rain stood in the water as a road sign, the vehicles were allowed to pass by, and the station was a few hours in the water. The feet were white, and the next day, a high fever was started. On July 12, the river dam broke the s224 line k6+. The subgrade of the Beibeigou Bridge section was washed away by the flood. He saw the head and jumped into the water. Everyone advised him not to fight hard. He insisted firmly: As the section chief, my position is in the first line, I don’t go into the water, I am in the water, I Who is not risky? ... In the floods of the day and night, he was rushing in the rain, wading through the mud, did not sleep a sense of stability, did not eat a normal meal, when the passing drivers and pedestrians looked at his bloodshot eyes and When you are tired and muddy, you will cast an admirable look. The crops of the relatives and friends of the old family were flooded, and the house was flooded and collapsed. He couldn’t take it back and look at it; the mother was seriously ill and he could not wait in front of the bed. Instead, she is a small family, and everyone is devoted to the flood fighting and rescue work.

At the beginning of the Spring Festival, a rare, continuous, large-scale low-temperature blizzard and freezing disaster swept through the provinces and cities in the middle and lower reaches of the Yangtze River. The rainy and snowy weather of the past day broke the originally tight and orderly daily maintenance balance, which had a huge impact on road transport, especially the snow on January 27 was aggravated by the highway traffic. Due to the volley of the bridge, the bridge surface is particularly prone to snow accumulation and is difficult to melt. As the chief of the industry, the rescue was his first reaction in bad weather and unexpected events.
