Structure for preventing pile head of prestressed concrete pipe pile from entering soil

The utility model provides a structure for preventing a pile head of a prestressed concrete pipe pile from entering soil. The structure comprises the prestressed concrete pipe pile poured in the soil, the surface of the plugging piece is in a circular truncated cone shape, the diameter of the thick end of the plugging piece is larger than the inner diameter of the tubular pile, the diameter of the thin end of the plugging piece is smaller than the inner diameter of the tubular pile, the thin end of the plugging piece is sealed, and the plugging piece can be clamped into a pile head of the tubular pile so that the pile head can be sealed. The tubular pile head plugging device has the advantages that the tubular pile head is directly clamped through the circular-truncated-cone-shaped plugging piece, plugging of the tubular pile head is achieved, the problem that a sandbag is scratched is solved, tubular subsequent soil digging is avoided, operation is convenient, the plugging effect is good, work efficiency is
