| Abstract: | This paper introduces the technology and construction quality control methods of pile bottom grouting for bored pile. The technology improves the load-bearing pile most effective, when bearing stratum is gravel layer in similar. The bearing capacity of single pile can be increased by 25%. A commercial office project in Wenzhou Fortune Plaza achieved remarkable technology results and economic benefits as result of adopting this technology. |
