摘要
针对中梁一级电站库区防渗工程中充填和半充填溶洞,采用了高压喷射置换和高压冲洗置换溶洞内充填物再灌浆的两种处理方案,通过取芯和压水试验检查,溶洞内的充填物得到有效置换,且透水率满足设计防渗要求。
Aiming at the filled and semi-filled caves in anti-seepage engineering in reservoir area of Zhongliang No.1 hydropower station,the high pressure spraying and high pressure washing were employed to permute the filled material in caves and regrout the caves.Through the examination of core drilling and packer permeability test,the filled material in caves were effectively permuted and the permeability satisfied the requirement of anti-seepage design.
