On December 5, Zhi copper four marks again to conquer important construction nodes, drag the left side of the bridge smoothly through.
The Tuochong super bridge is a Zhi copper high-speed control project, spanning Talushi River and Tuozhi highway, with a length of 1067m. The superstructure of the main bridge is (65+2×120+65) m four-span prestressed concrete variable section continuous rigid frame system. The main pier body is double-limb hollow thin-wall pier, and the maximum height of the bridge is 88m. The bridge is located in the mountain gully area, the mountain high road risk, the climate is changeable, the operating environment is very complicated, the transportation is difficult, the construction is difficult, the safety risk is extremely high, and the epidemic situation in Huaihua area during the construction is extremely severe, personnel management, material guarantee is extremely difficult, the project period, the construction organization put forward a severe test.
In order to overcome the construction difficulties, Zhi copper project team carefully organized, scientific planning, brainstorming. Optimize the proportion of high grade concrete to ensure the collapse degree of incoming mold; Optimize the hanging basket closing scheme and the temporary rigid support scheme of the closing section to ensure that the elevation of the cantilever end is stable. Through accurate measurement of the whole process of the hanging section, accurate data are provided for construction monitoring to ensure the final accurate closing. According to the site construction situation, the project team adhere to the daily safety production "pre-shift meeting", implement the "one time three card" system, do a good job of task decomposition, to the front-line staff in all aspects of safety and quality technology disclosure; Do a good job of epidemic prevention, for the bridge closure section production escort.
The construction was strongly supported and guided by the group company and the owner's supervision, while the project team led the front command. All the team members stuck to the construction line, carried forward the determination to overcome the difficulties and the courage to be the first. The construction quality and safety were effectively controlled.
