During the construction of deep-water drilling pile, the deformation of steel sleeve and suspension of concrete casting happens very often, which affect the construction quality of the pile body. Based on the experience of pile foundation treatment in Anzhou Jiajiang bridge and other projects, we optimize the treatment methods for the steel sleeve. Through the underwater cutting processing we solve the deformation problem of the steel sleeve. The pile connection in the sleeve is implemented after theoretical check, and the engineering problems are solved.
