摘 要: | 本文简单介绍了碗窑水库上游坝面闸门井水下渗漏检查和防渗施工情况。在查明上游坝面闸门井水下12m深处,混凝土蜂窝引起渗漏的基础上,采用杭州国电大坝安全工程有限公司研制的SXPBM、LW、SXM等水下防渗材料和水下施工工艺,直接在漏水源头-上游坝面完成了快速水下防渗堵漏施工,坝内排水管漏水量由>1000ml/s降为0.6ml/s以下,取得了堵水率99.9%的工程防渗效果。

Seepage inspection underwater and repair for upstream gate shaft in Wanyao Reservoir |
| |
Abstract: | This paper is about the underwater seepage inspections and anti-seepage constructions for the upstream dam face of roller concrete dam.Base on the acknowledgment of the underwater seepage positions and scopes of upstream dam face,applied with the underwater anti-seepage materials,such as SXPBM,LW,SXM and underwater construction technology,carried out the underwater anti-seepage construction on the upstream dam face which is the source of seepage.The seepage velocity of the drain pipe dropped from more than1000ml/s to0.6ml/s,the water shutoff ratio more than99.9%and good engineering anti-seepage benefit achieved. |
