No work is stopped during the holidays, and the project is not slowed down. During the National Day holiday, there is such a group of people, dressed in overalls and wearing hard hats, busy on the front line of the construction of major transportation projects in Guangdong.
At 8 o'clock on October 6, the concrete pouring of the 18th section of the No. 49 main tower of the main bridge of the Hongqi Lishui Road Bridge of the Shenjiang High-speed Railway was completed, and the construction of the main tower exceeded 100 meters, with a total height of 102.213 meters, and it is expected to be completed by the end of 2025 to reach 258 meters.
As the coastal passage of the main channel of the national "eight vertical and eight horizontal" high-speed railway, the new main line of the Shenjiang high-speed railway is about 116 kilometers long, and the main bridge of the Hongqili Road of the Shenjiang high-speed railway, which is undertaken by the China Railway Bridge Bureau, has a length of 1.41 kilometers and a main span of 808 meters.
The upper level of the bridge is an eight-lane urban expressway, and the lower level is a four-lane high-speed railway.
The H-shaped main tower is 258 meters high, divided into 47 sections of lower, middle and upper tower columns, each section is 6 meters high, and the intelligent tower platform climbing formwork method is used for construction.
The intelligent tower building platform is applied, and the intelligent climbing system, intelligent spray maintenance system, and intelligent mold removal system are configured...... In the construction process, smart construction is everywhere. At the same time, the data of the intelligent monitoring system is transmitted to the information dispatching center to realize the remote information management of the intelligent tower building platform system to ensure the structural safety and concrete construction quality of the main tower during the construction process.
The Shenjiang high-speed railway is an important component of the coastal passage of the main channel of the "eight vertical and eight horizontal" high-speed railways in China, and it is also a passenger high-speed railway that undertakes medium and long-distance passenger flows and intercity passenger flows in the Pearl River Delta. After the completion of the project, the Qianhai Free Trade Zone in Shenzhen and the Nansha Free Trade Zone in Guangzhou can be connected by high-speed rail in half an hour, which is of great significance to further build the "Greater Bay Area on the track".
