G3 Tongling Yangtze River Railway Bridge is a key project to implement the integrated development strategy of Yangtze River Economic Belt and Yangtze River Delta, and it is also the largest single investment project since the establishment of the city。Since the construction of the project officially began on January 4, the bridge builders have been racing against time to keep the progress。

　 On March 2, six rotary drilling RIGS were drilling simultaneously at the construction platform site of Jiangbei No. 3 main pier of Tongling Yangtze River Gongtie Bridge;Six percussion drills are being drilled at Pier 2。The project site machinery roar, crowded, hundreds of bridge builders in their respective posts in an orderly operation。Pile foundation is an important part of pier structure, which carries the huge pressure of cap and pier。There are 68 drilled piles in Pier No. 3, each with a diameter of 3 meters, a pile length of 95 meters, and a hole depth of 122.5米。

　 Pan Meng, technical director of No.3 pier of G3 Tongling Yangtze River Railway Bridge Project Division, China Railway Bridge Bureau: As of this morning, we have completed the pouring work of the 17th borehole pile, and the installation of the steel cage of the 10th borehole pile is under way。Our planned construction period is to carry out the construction of the lower foundation until May, that is, the construction of our drilled pile. After the construction of the drilled pile is completed, we will install the cofferdam。Since the start of the project, we have been in a rush to meet the deadline, rush the deadline, basically 24 hours non-stop operation。At present, our construction progress fully meets our requirements, and there are still over-completion。

　 G3 Tongling Yangtze River Railway Bridge is a double-deck cable-suspension system bridge, pier No. 3 and Pier No. 4 are the two main piers of the bridge, carrying 988 meters of the main span across the river。At the operation site of Pier No. 4, across the river from Pier No. 3, four rotary excavators are drilling simultaneously。According to the friction pile design, there are 64 drilled piles in pier 4, and 9 concrete piles have been poured。From north to south, the two main piers are the key control points of the whole bridge, in order to ensure the construction progress, the bridge builders took out the attitude of "start the decisive battle, start the sprint", the Spring Festival does not stop, the rain and snow are still dry, to ensure the smooth progress of the two main piers according to the construction node。

　 China Railway Bridge Bureau G3 Tongling Yangtze River Railway Bridge Project Department 2 Branch 4 pier site technical person Cui Xiang: In order to complete our Tongling three bridge dream, for Tongling people to cross from this bridge as soon as possible, there are actually many people like me on our site, are holidays to stick to their posts。In the case of bad rain and snow weather, none of the workers on the site will get cold feet, and our normal work will not be affected by bad weather。
