Mechanical technician work summary
I studied mechanical engineering at Harbin Railway Engineering School from December 1976 to December 1978, and then studied in Harbin Vocational University Railway Engineering from September 84 to June.
From 1988 to 1990, he was responsible for the technical work of the construction of large-aperture bored piles with a diameter of 1.8m at the site of the Sichuan Yongjiang Bridge. And directly involved in the construction of reinforced earth embankment, double-guide beam and 20m post-tensioned prestressed beam. In the past three years, due to his active work, he has made due contributions to the smooth completion of the bridge. Especially when the 1.5t heavy drill bit was buried in the hole 16m deep due to the sudden flood, the design was not changed. Instead, a special treatment method was adopted, and the drill bit was finally salvaged and received. The owner is highly praised. In the construction of reinforced earth embankment, we found that different design theories will have different design results, and then contact with the design unit, combined with the actual situation of the site, re-checked, and a large number of embankments in some sections were reduced. The number of belts has increased the benefits for the company. The Lancang Bridge was awarded the Quality Engineering and Excellent Management Award by the owner. Due to my active work, I was promoted to an engineer in 90 years.
In the second phase of the Jinan North Ring Project, I worked as the technical director of the 9th team and directly participated in the construction of the 16msrc steel beam of the Ministry of Railways scientific research project, and accumulated a lot of information and experience. Especially in the renovation of the station station of Jinan East Railway Station, the design requirements are to raise the height of the existing bridge pier and replace some of the beam body under the condition of ensuring the open-air traffic, which is a very arduous project. Due to the reasonable preparation of the organization, the on-site organization is strong, that is, the safety quality is guaranteed, and the construction period is guaranteed, which has created good economic benefits.
In the construction of Jiaozhou Bridge of Jiaohuang Railway, I adopted a special design for the pier cap formwork. The reserved bolts on the pier body were used to establish the working platform. There was no ground support, and there was no one lacing inside the raft, which reduced the labor intensity. Increased work efficiency and increased surface finish of tantalum.
In the construction of the Heri Double Line, as the chief engineer, he presided over the full technical work of 58.4km including 180 bridges and culverts, roadbed engineering, track engineering, water supply and drainage engineering, housing construction engineering, communication signal engineering and electric power engineering. The implementation of the construction organization design and the three station reconstructions of the full-scale section and the development of the transition plan of the three divisions were prepared.
In the design of the slab formwork of the Zhaoxin River Bridge, the technical means is adopted, and there is no lacing inside the raft, which increases the appearance and creates the necessary conditions for the creation of the fine works. For the construction of the 46-seat culvert bridge in the whole section, different construction schemes were adopted, and the construction was always in the best control state from the technical point of view.
There are only one hole 12m beam and one hole 8m beam in the five sections of the Heli double line. It needs to be prefabricated on site. The cost of making a set of templates is very high. I went around and finally found the same model template in the Lanyan line brothers, which saved the enterprise. funds.
In the construction of the 26#~30# pier and excavation foundation of the Jiaohe New Line, the No. 2~30# pier, the geological condition was encountered due to the middle sand layer with the surface layer of 3~4 m thick, the sandstone with the lower part and the extremely rich groundwater. More complicated, the construction has been blocked again and again. Under this condition, the steel sheet pile can't do anything because it can't enter the sandstone; the large excavation and straw bag cofferdams are extremely rich in groundwater, and the sand layer can not be excavated due to siltation, and the sinking well cannot be implemented because the basic size is too large. Finally, the construction method using the existing 12.5m long I50 I-beam cofferdam sinking was adopted, which greatly accelerated the construction progress, reduced the cost and ensured the project quality.
After entering the pier and pier body construction, in order to ensure the realization of the goal of excellence, the appearance quality of the pier and pier has become a key difficulty. With the strong support of the headquarters, high-precision stencils and advanced mechanical equipment have laid a solid foundation for Chuangyou Engineering, and the optimization of construction technology has become the key. To this end, I organized the construction and technical personnel of the participating units to visit and learn from the neighboring brothers. I was eager to select the raw materials, the reinforcement of the formwork and the treatment of the joints, and organized the technical personnel to set up the quality control of the pier concrete. The group, and the team leader, proposed one optimization solution for the joint processing of the template. The investigation selected the new material dbf high-performance mineral ultrafine powder as the admixture of concrete. This new material reduces the hydration heat of concrete and increases the compactness of concrete. It is also designed with diesel, engine oil and hydraulic oil mixture. Template isolating agent; at the same time, the template joint is made of 6mm thick and 9cm wide rubber strip with 2-3 layers of double-sided rubber strip to ensure the seam is tight and not leaking. The adoption of these measures guarantees the quality of the appearance of the concrete.
Among the 84 projects recommended by more than 20 bureau-level construction units of Jiaoxin Line, only the 2597m Longhe River 2# Super Bridge was rated as the only “best project” in the whole line, and was completed in the completion acceptance. The excellent project passed the acceptance of the takeover unit. At present, it is applying for quality projects at the bureau level and ministerial level.
In order to achieve the goal of overall excellence in the whole bidding section, the construction of small concrete precast parts such as pedestrian pavement walking boards and platform cap stones in the whole bidding section was investigated, and the construction method of rubber molds was investigated, so that the appearance quality of concrete prefabricated parts was greatly improved. Improvement.
At the end of XX, I came to the Jiaoji line and directly participated in the construction of the 200km electrification project. Due to the large density of existing traffic, the absence of lines on the main line, the difficulty of wide bridges, the difficulty of construction, the high technical requirements, and the tight schedule, we have carefully prepared each construction plan to ensure the safety of the existing traffic. It solves many technical problems such as the construction of the existing compacted piles, the construction of the iii-type pillows, the determination of the best proportion of the graded gravel, the line reinforcement during the bridge width construction and the sc325 ballast welding.
In order to accumulate good experience and practices and actively promote it, I published an article entitled "Concrete Surface Enhancement Technology" in the third issue of "Technology Communication" magazine edited by the Bureau of Science and Technology; in Shandong Deep Foundation Engineering Association The article "Shandong Deep Foundation Engineering" edited by the editor-in-chief "The Application of Grouting Bag Piles in the Reinforcement of Railway Bridges and Culverts" was published in the second issue of XX, and was published in the fourth issue of Science and Technology Newsletter XX. "Computation and Control of Multi-head Track Construction", "Cartridge and Culvert Rapid Jacking Construction and Economic Analysis", "Summary of Grouting Bag Pile Construction Technology", and published in "Technology Newsletter" XX Year 2 A paper on the safety technical measures for the construction of cable bridges and culverts. In the fourth issue of the "Technology Communication" magazine of the Bureau of XX, the paper published "The Protection of Hydraulic Spraying and Planting Grass Slope" and the "Two Wires for Time-limited Manually Inserting Ballasts"; the "Surface of the Weihe No. 2 Bridge" Quality Control was also published in the XX Technology Newsletter.
The paper won the second prize of the 22nd qc group achievement in the article "The quality control of existing line reinforcement when jacking large-span oblique frame bridge"; the quality control of concrete pier construction of "Luohe 2# special bridge" won the 23rd The second prize of the second qc group results.
In the second edition of the XX year of the ministerial publication "Railway Standard Design", a paper entitled "Quality Control of Concrete Pier Construction of the Weihe 2# Super Bridge" was published. Since I was engaged in technical work in 1987, I have participated in the construction of Sichuan Xinjin Yongjiang Bridge and the second phase of Jinan Beihuan Railway, Jiaohuang Line, Jingjiu Line, Qinglin Line, Shandong Zaozhuang Road Bridge, Blue Smoke Phase I Double Line, He Construction of roads and railway projects such as the daily double-track line, the new rubber line, and the electrification transformation of the Jiaoji line. In November XX, I was named the seventh batch of young and middle-aged scientific and technological talents by the group company; in February XX, I was awarded the “Advanced Individual” by the Jinan Bureau of the Heli Double Line Construction Headquarters in XX; “Excellent Science and Technology Workers”; in December XX, it was awarded “Excellent Commander” by Jinan Bureau Jiaoxin Command. In October XX, he was appointed as a senior engineer by the group company. In the future, I will work harder and make full use of my wisdom and sweat to make my due contribution to the company's revitalization and glory.
