Shiqiao Shiplock downstream anchorage engineering soil condition is very poor and the un-derground water level is high.The high strength PHC prestressed pipe pile for reinforcing soft soil foundation is adopted in the project.According to the characteristic condition,the pile sinking tech-nology and the treatment of pile top and bottom connection for prestressed concrete pipe pile are stud-ied.Effective measures to control the position accuracy of pile sinking when pile length up to 6.38m, reduce the surface exposed time and ensure the connection quality of pile top and bottom under the conditions of large excavation in soft soil foundation are performed and good effect has achieved.
