Jixian Gao Rail, Zheng Duan officially opened to traffic

Correspondent Wang Guansheng

On June 20, the Jixian (south) Zheng (state) high -speed railway Zheng Duan was built by the 14th Bureau of China Railway, the 16th Bureau of China Railway, the 18th Bureau of China Railway, the 19th Bureau of China Railway, and the China Railway Construction. The provincial "rice" font fast railway network is fully completed.

Jixian High -speed Railway Grand Canal Bridge

The Jixian high -speed rail is the regional connection line of my country's "eight vertical and eight horizontal" high -speed railway network, and it is also an important part of the "rice" glyph -shaped high -speed railway network strategy in Henan Province. The Zhengzheng Duan positive line is 197 kilometers long and the design speed is 350 kilometers per hour. There are 7 stations on the entire line.

According to reports, the 42-kilometer Grand Canal Bridge is a heavy-duty project throughout the board. It adopts currently the most advanced CRTS-III-type boardless orbit board construction process in China. In order to ensure the quality of no orbital construction, during the construction process, the builders strictly control the technical parameters of the concrete mixing and the performance, strength of the object, and strictly control each process. The construction plan ensures the smooth completion of the no -orbital rail construction.

Slipping station building during construction

The Grand Canal Bridge crosses the Weihe River twice, and the soil on both sides of the strait is very soft. The depth of the pile foundation pit is about 40 meters, so the risk of collapse of the foundation pit is extremely high. In order to ensure construction safety, they carried out scientific and technological research, optimized construction technology, and greatly improved the safety factor.

After the completion of the Zheng Duan of Jizheng Gao Rail, it will further improve the national road network structure, fill the gap in the high -speed rail in northeast Henan, and at the same time improve the efficiency of Zhengzhou and Jinan. With the official landing of the last "skimming" of the "rice" glyph high -speed rail, it will provide important support for the integration of the "Belt and Road" construction and the construction of a "dual -cycle" new development pattern.
