摘要
为确保防渗墙墙体防渗效果和施工工期要求 ,在防渗墙大规模施工前进行了振孔高喷、常规高喷、钻喷一体化和自凝灰浆防渗墙等成墙工艺的现场试验 ,试验结果说明四项成墙工艺均可用于三峡工程三期土石围堰防渗墙。
The volume of the cofferdam (3rd-phase)of TGP is very large and its construction is pressed for time. For ensuring that the impervious core of the cofferdam has a good quality and could be completed in time limit, a number of tests are carried out before its construction, i.e. high-pressure vibro-grouting as principal with conventional grouting as supplementary, drilling and grouting simultaneously, self-setting mortar grouting etc. The results show these technologies are preferable for the cofferdam construction.
