Abstract

The invention discloses a foundation pile for a building. The foundation pile comprises a pile driving frame, wherein the top of the pile driving frame is fixedly connected with a rammer; the upper surface of the pile driving frame is in sleeve connection with a pile body; the bottom of the pile body is movably connected with a pile head device; the pile head device comprises a pulling block and a chuck device; the outer surface of the bottom of the pile body is in sleeve connection with a pile head shell; the outer surface of the pile body is fixedly connected with the chuck device and the pulling block respectively; the pulling block is arranged in an inner cavity of the pile head shell and is adaptive to the inner cavity; a side pressing device is in sleeve connection with an opening of an inner wall of the pile head shell; the bottom end of the pile head shell is fixedly connected with a protection block; and a pressing block is arranged at the bottom of the inner cavity of the pile head shell. The invention relates to the technical field of buildings. According to the foundation pile for the building, the pile body is hit through the rammer so that the foundation pile for the building is pressed to move downward to enter soil; the pile head device is arranged at the bottom of the pile body so that the effect of protecting the bottom of the pile body in an underground high-pressure environment is realized.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a foundation pile for construction. Background technique [0002] Pile foundation is a deep foundation that connects the tops of several piles into a whole through caps to bear dynamic and static loads together. Pile is a vertical or inclined foundation component set in the soil, and its function is to pass through the weak high compression The soil layer or water transfers the load borne by the pile to the harder, denser or less compressible foundation rock layer. We usually refer to the piles in the pile foundation as foundation piles. [0003] When traditional piles are rammed into the foundation, multiple rammings make the piles pass through the soft soil layer and enter the hard rock layer. However, because the piles are underground when they are rammed, and the depth of the rock layer is unknown, it is not clear when the piles will touch the rock layer. , resulting in...
