Abstract: Compared to the normal pile foundation, implanted rocksocketed steel pipe piles can provied better bending and pullout resistance.The project of Ningbo GangXin Oriental Fuel Provision Company,is located in Beilun Dstrict of Ningbo.Totally 106 were constructed in this project,34 of them are implanted rocksocketed steel pipe piles.The maximum saket length is 20m underwater,being disturbed by the waterflow,the constructiong is very difficult. Therefore lots of methods have been taken to assure the quality of it.This paper summarizes the construction program and the process of implanted rocksocketed steel pipe piles in this project ,thich could provide a reference for similar projects.

Key words: Pile construction, implanted rock-socketed steel pipe piles, underwater construction
