王大坑水库低弹模混凝土防渗墙施工技术

The construction technology of low elastic modulus of concrete cutoff wall in a reservoir

本文通过低弹模混凝土防渗墙在水库除险加固工程中的应用,系统阐述低弹模混凝土防渗墙作为病险水库坝体及坝基防渗处理的一种常规、有效的方法,并从导墙施工、成槽工艺、固壁泥浆、清孔、墙体材料填筑、特殊情况处理等方面论述了混凝土防渗墙的施工技术,论证了低弹模混凝土防渗墙作为防渗体的优越性,阐述了土坝混凝土防渗墙施工中常见的特殊情况处理办法。

Through the application of low elastic modulus of concrete cutoff wall in the reservoir danger control and reinforcement project,this paper describes low elastic modulus concrete anti-seepage wall as a conventional and effective method in dam seepage control.Besides,the author discusses concrete cut-off wall construction technology,it＇s superiority,and explains the special circumstances of the common approach in construction.
