The Shanghai-Chongqing-Chengdu high-speed rail is a high-speed rail artery connecting the eastern, central and western parts of China. As the first section of the Wuyi section of the Shanghai-Chongqing-Chengdu high-speed railway, the 5 bids won by Canlon are located in Jingmen City, with a total length of 47.18 kilometers and a total investment of 4.218 billion yuan. Starting from the east bank of the Zhongxiang Hanjiang Railway Super Bridge and ending at the Jiaoliu Line across the Super Bridge in Suji Village, Zhanghe Town, Zhanghe New District, 18 bridges and 3 tunnels will be built. Today, we walked into Tianjia Tunnel together to witness the specific application of Canlon self-adhesive waterproof and drainage board in this project

Canlon self-adhesive waterproof and drainage board is mainly composed of concave-convex waterproof and drainage board and adhesive tape. The "Velcro" adhesive tape on the surface can be directly bonded to the non-woven buffer layer. The edge has its own welding selvedge, which can facilitate the waterproof and drainage board to be firmly welded into one body, and has the advantages of good waterproof performance, good drainage effect, and simple and fast installation method.

Compared with the conventional waterproofing board, Canlon self-adhesive waterproofing and drainage board fully considers the drainage needs of the tunnel at the beginning of the design, effectively guides the drainage function, and avoids the erosion and damage of the structural concrete caused by the concentrated flow of surrounding rock water.

At present, the construction of the Shanghai-Chongqing-Chengdu high-speed railway is progressing in an orderly manner. Canlon's integrated waterproof system will also continue to help promote the construction of the "Yangtze River Delta on Track" to accelerate further,making unremitting efforts for the connection of the Yangtze River Delta urban agglomeration, the urban agglomeration in the middle reaches of the Yangtze River, and the Chengdu-Chongqing economic circle.
