Chongming Line Beigang Dram Structure Conversion Fail Structure Covered

At 10 pm on August 7, at the construction site on the east side of the Shanghai Yangtze River Bridge on the G40 Shanghai -Shaanxi Highway Shanghai -Shaanxi Highway in Changxing Island, the concrete pump truck was carrying the final pouring operation of the foundation pit. This marks the capacity of the Shanghai Rail Transit Chongming Line 111 standard 2#shield conversion section of the Shanghai Rail Transit Line of the Shanghai Tunnel.

The 111 bidding project successfully achieved the main structure of the main structure after the project construction and resumption, which created favorable conditions for the promotion of the entire project construction of the Chongming Line.

Since the Chongming Line launched the re -production and re -production in May, the construction units of various projects strictly follow the principles of "the first serious epidemic prevention, ensure safety, take into account the needs, and advance in order". , Go all out to open up horsepower, overcome the impact of high temperature, and ensure the completion of the annual construction tasks. The Chongming Line is the premiere of the Chongming Two -wing transportation pattern and the starting line of the "Fourteenth Five -Year Plan" start of the Shanghai Rail Transit.

At the same time, as the longest -diameter mud water balance shield structure tunnel of the longest -diameter mud water balance shield structure of domestic rail transit, the Chongming Line 108 and 111 target shield conversion segment on Changxing Island will be the Chongming Line Yuejiang Single Cave Double Line. The large shield and the dual -cave dual -line small shield at Changxing Island Station are also one of the most important and most critical engineering nodes to achieve the most important and critical engineering nodes through the Yangtze River.
