萧山东江闸绕壁渗漏加固处理

Wall Leakage Reinforcement of East Gate in Xiaoshan

水闸施工和建成后,绕壁渗漏是较为常见的问题,由于上、下游水位差,在闸基及边墩和翼墙的背水一侧产生渗流,会降低了闸室的抗滑稳定及两岸翼墙和边墩的侧向稳定性,并可能引起地基的渗透变形,严重的渗透变形会使地基受到破坏,损失水量,使地基内的可溶物质加速溶解等.结合绕壁渗漏问题在东江闸工程中的具体处理过程,分析了实际施工中的工序细节处理与质量控制.

Wall leakage is a common problem after sluice construction due to the different level head of upstream and downstream,which leads to side seepage in sluice foundation,abutment back and wing walls.It reduces the ant-sliding stability of the chamber and the side-direction stability of the wing walls.It may also cause seepage deformation of the foundation seriously,which may destroy the foundation,even result in crash.Meanwhile,the loss of water accelerates the dissolution of soluble substances in the foundation.The reinforcement of wall leakage in Jiangdong Gate is mainly introduced in this article,and the specific treatment and quality control in the actual construction process are also discussed in detail.
