The construction of heavy difficulties in the entire line has made another breakthrough progress, and it is about to enter the entire line of the rail paving.

Yangcheng Evening News reporter Li Zhiwen, correspondent Lin Qunhai and Chai Jingling Photography report: At 16 o'clock on September 13, the Guangshan high -speed rail Zengjiang Extra Bridge successfully met the dragons, marking another breakthrough progress in the construction of the Guangshan High -speed Railway's heavy difficulties. After the bridge, the Guangshan high -speed rail construction will enter the entire track laying stage.

The Guangshan High -speed Railway is one of the key projects in Guangdong Province. It is established by the Guangzhou Railway Group's Guangzhou Engineering Construction Headquarters and the China Railway Guangzhou Engineering Bureau.

The Guangshan high -speed rail starts from Guangzhou Xintang Station to Shanwei Station. The Zengjiang Extra Bridge is a dual -tower and double cable surface concrete cable -keeping bridge. The bridge is located in Shidan Town, Zengcheng District, Guangzhou, with a total length of 2569.480 meters. The main bridge is spanning 260 meters across the Zengjiang waterway.

The main bridge of Zengjiang Extra Bridge was constructed for the first time in the construction of high -speed railway cable bridges in the world. The phenomenon, at the same time, uses a large shear key to improve the shear performance of the stitching of the beam body. The assembly of the section beam is effectively combined with the effects of the longitudinal coarse stress steel rod and the bonding glue, which connects the section beams into the whole as a bridge. Railway driving comfort and safety. This innovative technology has become a new benchmark for domestic high -speed railway construction.

According to the relevant person in charge of the Guangzhou Engineering Construction Headquarters, the main bridge construction process is large, the process is complicated, the accuracy control requirements are high, the bridge line is not easy to control, the construction difficulty is high, and the safety risks are high. In December 2019, the railway department set up a key topic for key topics of the "Guangshan high -speed rail large span section prefabricated concrete chinensis bridge key technology and intelligent research", and overcome relevant problems as scheduled.

The Guangshan High -speed Railway Unicom, Beijing -Guangzhou, Beijing -Hong Kong high -speed railway and coastal railway are important parts of Guangdong Province's "five vertical two horizontal" high -speed railway network. After the Guangshan high -speed rail is opened to traffic, the travel time from Guangzhou to Shanwei will be compressed from the current 2 hours to the fastest 40 minutes. Passengers along the route will be more convenient, smooth, comfortable and convenient. We will improve the construction of the Guangdong -Hong Kong -Macao Greater Bay Area comprehensive transportation system, build a "1 hour economic life circle" in Guangzhou, and promote the integrated development of the Guangdong -Hong Kong -Macao Greater Bay Area to promote the rural areas. Revitalization is of great significance.
