In view of the common quality problems of precast core column rock-socketed steel pipe pile,such as rolled edge of steel pipe pile,stuck drill and eccentric reinforcement cage,the causes and effects are discussed.We adopt methods for quality control which includes reasonable control of steel pipe pile penetration degree and other standards for pile sinking,pile tip using external reinforcement,improved hammer and other methods.The quality of precast core column rock-socketed steel pipe piles before and after construction improvement in the first phase of Wuhan Xingang Sanjiang port area integrated wharf project is compared and verified.The results show that the control standards for precast core column rock-socketed steel pipe piles should not be too strict.At the same time,it is suggested that the external reinforced steel pipe pile tip should be adopted in the design,and the cylindrical punching hammer should be used in the construction to effectively solve the problem of drill sticking in the construction process of pile foundation.The improved hammer or the hydraulic drilling method can effectively improve the quality of precast core column rock-socketed steel pipe pile (inclined pile）.
