1 工程概况白龟山水库自建库以来多次在顺河坝鱼陵山坝段发生漩涡、漏水等现象,经多方多次勘探查明该段产生渗漏原因为该坝段坝基有风积沙层分布,结构疏松,且已贯穿大坝上下游,在水位作用下存在渗漏及渗透稳定问题,直接威胁大坝安全,为此进行截渗处理。2 混凝土截渗墙施工方法:混凝土截渗墙设计厚度为22cm,深度为5.0～7.3m。2.1 锯槽机成墙工艺 1 Project Overview Baiguishan reservoir since the reservoir several times in the dam Yueling Hill swirl, leaking and so on, after multiple exploration to identify the reasons for the leakage of the dam section of the aeolian plot Sand distribution, loose structure, and has run through the dam upstream and downstream, under the action of the water level there is leakage and stability problems, a direct threat to the dam safety, for this cutoff treatment. 2 concrete cutoff wall construction methods: concrete cutoff wall design thickness of 22cm, a depth of 5.0 ~ 7.3m. 2.1 sawing machine into the wall process
