Abstract：
Reverse drainage caisson-type breast wall not only has the function of open caisson,but also has the advantages of simple structure and low cost at the same time,besides,it can realize the linkage construction between single pile and multi pile, Solve the problem of artificial digging hole pile in complex area, Keep the advantage of low construction cost of artificial digging pile.This paper is combined with the specific engineering case,describe the scope of application of reverse drainage caisson-type breast wall in the manual hole digging pile,and hope it can be a reference for other similar projects.
