The structural forms of sheet pile wharves are increasing in foreign construction projects,and the sheet pile walls and breast walls of wharves are mainly divided into two types:onshore construction and over-water construction.Onshore construction requires early filling of cofferdams,which incurs high construction costs and prolongs the construction period;the over-water construction process of the breast wall is complicated and the construction safety risk is large,which has a certain impact on the project schedule and quality.This paper introduces the process of sheet pile pier breast wall for the Persada 6B berth project in Obi Island,Indonesia.The project uses a torque balanced bottom formwork design,which avoids underwater welding operations by suspending the bottom formwork and installing it as a whole.The torque balance conditions of the bottom formwork during construction are analyzed and calculated,and the process is successfully implemented through project practice.
