On Technology Analysis of Concrete Lining in Tunnel Section of Water Conveyance Project of Chao'er-Xiliao
In order to discuss the construction technology of concrete lining of water conveyance tunnel,combined with the construction practice of fifth lot for the tunnel section of water conveyance project from Chao'er to Xil-iao,the key technical points of concrete lining construction are analyzed,including the selection of construction equipment,the mix ratio of lining concrete,the construction of water drainage and blocking in cave,and the spe-cific application results are put forward.The practice concludes that concrete lining construction has long been the difficulty and key point of the construction of water conveyance tunnel,which determines the overall quality of the project.In actual lining construction,strict control of equipment selection,full drainage and water bloc-king in the tunnel,the selection of optimal mix ratio of concrete and the conduct of key points of concrete lining construction are vital to improve the concrete lining effect of water conveyance tunnel project,which is worthy of great attention in the actual construction.
