液压抓斗地下墙施工在施庄水库防渗中的应用

Application of hydraulic grab underground wall construction in Shizhuang Reservoir seepage control

施庄水库由于呈不规则形状,周围多建筑物,且工期要求短,决定采用液压抓斗地下防渗墙技术进行防渗施工。本文详细介绍了液压抓斗地下防渗墙施工技术的工艺原理、施工流程,以及施工方法。实践证明:采用该技术,施工速度快,开挖深度大,成槽精度高,适应性强,且工程完工后,水库水量损失减小显著,防渗效果好,值得在水库防渗工程中推广应用。

Since Shizliuang ReseGoir has irregular shape, many surrounding structures and short construction durationrequirement, it is decided to adopt the hydraulic grab underground cut-off wall technology for anti-lethe paper, the process principle, construction flow and construction method of hydraulic grab underground cut-off wallconstruction technology are introduced in detail. It is proved by practice that the technology has the advantages of fastconstruction speed, deep excavation depth, high slotting precision and strong adaptability. After the the water loss in reseroir is significantly reduced. The anti-seepage effect is better. It is worth promotsimilar reseroir anti-seepage projects.
