Abstract: The screw compaction cast-in-place pile is constructed as follows: the screw-squeeze auger is driven in soils and clockwise rotates and uplifts when the concrete is pumped at the bottom of the pile, and the rebars are back-inserted in the center of the concrete in the pile hole. The squeeze compaction of the soils around the pile and the cementation between the pressure pumping concrete and cobble stone and crushed stone layers results in great increase of the bearing capacity of the pile.
