| Abstract: | In several highrise building construction projects with karst development foundation in Taiwen area, the premixed dry material method is used to assist anchor bolt grouting, which will successfully solve the leakage problem of anti floating anchor bolt grouting under the condition of karst foundation site, ensure the quality of anchor bolt grouting anchor solid, improve the grouting efficiency, and receive good economic and social benefits. In this paper, successful application of the construction method of premixed dry materials (cement, sand and admixture mixture) in the construction of anti floating anchor bolt in the leakage site of karst development has been introduced. It has a good demonstration and reference value. |
