Abstract:The labour-dug pile is widely used in foundation engineering. Grouting process will be introduced to labour-dug pile technology, you can avoid the water gushing in the process of manual excavation, sand the phenomenon of risk, and may reduce the depth of excavation. Cement paste with the weak foundation soil combine to form a composite foundation, can improve pile bearing capacity. In this paper, engineering practice, right after the grouting pile test results show that the application of technology in this project is successful. The technology is available for similar projects for reference applications.
