Shanghai -Chongqing High -speed Railway Yangshu River Bridge enters the beam construction stage

Hubei Daily News (Reporter Zheng Lan Correspondent Yue Li Wang Zhidi) On September 26, the construction site of the Wuyi section of the Shanghai -Chongqing high -speed rail, the first cross -Liang Liang No. 0 of the Yangshu River Bridge was completed, marking the official construction of the project construction Entering the construction stage of the beam body laid the foundation for the early opening of the beam channel.

This time the pouring block 0 is 11m long, of which the top of the pier is 4m long, the cantilever ends on both sides are 3.5m, the bridge deck is 7.4m, the bottom width is 4m, and the amount of pouring square is 206.27 square meters. For 13 hours, the entire block weighs 536 tons after pouring.

In order to make this behemoth accurately placed at the top of the pier, the project department of the Seventh Bureau of China Construction Organization has organized a special meeting to discuss the construction plan. The pouring process uses the measurement personnel to follow the whole process to accurately review each coordinate to ensure that the bridge is linear and accurate. In key procedures such as template assembly, stent setting, steel bars bundling, prestressed pipe installation, concrete pouring, etc., technicians are meticulous on the spot.

The structure of the continuous beam 0 is complicated, and the internal reinforcement and prestressed pipeline are dense, which has a great impact on the vibration work of concrete. In order to overcome this problem, the project department of the China Construction Seventh Bureau has organized a technical research team to optimize the template to optimize the template to optimize the template Essence After careful discussion and deduction, add 4 small windows to the templates of the continuous beam 0 to facilitate the vibration of concrete and provide a strong guarantee for improving the construction quality of the continuous beam 0.

The total length of the Yangshu River Bridge is 736.70 Yanmi (the length unit of the irregular components in the project). It is the main line of the Shanghai -Chongqing high -speed railway high -speed railway of the national "eight vertical and eight -horizontal" high -speed railway network. The construction of the Shanghai -Chongqing high -speed rail will run through the six provinces of the East and the West, connecting the three major urban agglomerations of the Chongqing, the middle and lower reaches of the Yangtze River, and the Yangtze River Delta, which benefits the 600 million population and is of great significance to promote the integrated development of the Yangtze River Economic Belt.
