Modern Express News (reporter Li Na) On October 26, the Modern Express reporter learned that recently, the first underground continuous wall steel cage of the Nanjing Jianning West Road River Crossing River Passage Jiangnan Junction East Extension Project was successfully troughed and the concrete pouring was completed, and the project entered the main construction stage.
The first section of the East Extension Project was constructed by the 12th Bureau of China Railway, and the first underground continuous wall was 1m thick and 29.1m deep, and the bottom of the wall entered the weathered rock layer of about 5.6m. The total length of the lot is about 361m, mainly including open tunnel engineering, pipe curtain tunneling engineering, drainage engineering, sponge city and road engineering. The construction of the first underground continuous wall unveiled the prelude to the comprehensive construction of each bidding section of the main project.
In order to give full play to the function of the Jianning West Road Crossing River Channel, share the traffic pressure of the Nanjing Yangtze River Bridge, facilitate the rapid crossing of the river in the northern part of the city, and alleviate the congestion of the nodes of the Chengxi Trunk Road and the South Bridge Road, Nanjing implemented the Jianning West Road Crossing River Passage Main Line Tunnel East Extension Project. The total length of the project is about 1622m, the starting point takes over the main line tunnel of the river channel and still follows the Jianning West Road to the east in the form of a tunnel, and a pair of import and export ramps are set up after passing through Yifengmen, and the main line continues to the east through the Lion Mountain City Wall, the moat, the South Bridge Road and Siping Road, and connects to the current Jianning Road in front of JinchuanHe West Road.
Since the start of construction, the Nanjing Municipal Public Works Construction Center has successively organized and completed the demonstration of important construction plans such as the protection of national cultural relics, the temporary diversion of the moat, and the replacement protection of the bridge on the south bridge road of the project, and conducted in-depth research with relevant departments on the comprehensive planning of pipelines and ground traffic guidance and reform, laying a solid foundation for the comprehensive development of the project.
