Aiming at the problem that the PHC pipe pile on the inclined riprap embankment is difficult to penetrate the thick riprap layer during the pile sinking process,this paper takes a comprehensive pipe frame project as an example to conduct a practical research on the construction technology practice.On the basis of comparing the conventional hole-leading technology,the solution of the DTH hammer first leading hole and then applying the prestressed concrete pipe pile is proposed.Furthermore,the equipment and technical parameters,construction process,problems existing in the hole-leading process and corresponding solutions are briefly introduced.The application results show that the prestressed concrete pipe pile after the DTH hammer leading hole can efficiently penetrate the riprap structure layer,the structural integrity of the pile body after the pile sinking is good,and the vertical bearing capacity of the single pile meets the design requirements.The research results can provide reference for similar foundation pile sinking construction.
