| Abstract: | The process of long - spiral drilling vibration - ramming inserting bars pouring pile is introduced. It is based on the long - spiral drilling method and two important stages of vibration - ramming inserting bars and pouring concrete at the bottom of the hole are added into the method. By test this combination of differ- ent processes can greatly increase bearing capacity of single pile and its deformation requirement, and make the best utilization of pile body strength. This process has good application value and utilization prospect. |
