| Abstract: | 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. |
