Prefabricated hollow pile foundation and high-pressure grouting method thereof
The invention provides a prefabricated hollow pile foundation and a high-pressure grouting method thereof. The prefabricated hollow pile foundation comprises a flexible bag, a steel pile tip and a connecting plate, and the top of the flexible bag is connected with the bottom of a prefabricated hollow pile through the connecting plate; a grouting port valve port in the middle of the connecting plate is connected with a grouting pipe in the prefabricated hollow pile; and a steel pile tip is mounted at the bottom of the flexible bag. After pile sinking, through high-pressure grouting, the flexible bag expands and extrudes a soil body at the pile end, the pile end is expanded, meanwhile, a soil layer at the pile end is compacted, the bearing capacity of the pile end is greatly improved, pile settlement is reduced, meanwhile, the grouting amount is controllable, and the bearing capacity of the pile is controllable.
