Brief introduction of Shanghai Tunnel Engineering Co., Ltd.

1965, Shanghai Tunnel Engineering Company was established, becoming the earliest engineering construction unit in China to carry out shield tunnel test and engineering application. From August 1965 to September 1970, the first river-crossing tunnel in China, Shanghai Dapu Road Tunnel, was completed. Self-developed φ 10.2 m grating extrusion shield was used to excavate 1322m at the bottom of Huangpu River. Combined with the four key technologies developed by the project, such as shield tunnel, tunnel lining and continuous caisson, 65438+ was obtained.
