Reinforced building pile foundation

Abstract

The invention discloses a reinforced building pile foundation in the field of building pile foundations, and the reinforced building pile foundation comprises an outer pile, a spiral piece is mounted on the outer wall of the outer pile, a drill bit is mounted at the bottom end of the outer pile, a thread is arranged on the outer wall of the drill bit, and a second cavity is formed in the outer pile. The outer pile driving efficiency is improved through the spiral piece and the drill bit, the spiral piece forms tension to the ground, the outer pile cannot move, and the pile foundation strength and the shock resistance and pressure resistance are effectively improved; a plurality of clamping blocks are arranged on the outer wall of an inner pile, a plurality of steel bars are arranged in the clamping blocks, fixing blocks are arranged between the clamping blocks, and reinforcing columns are arranged in the fixing blocks, so that the strength of the inner pile is enhanced, cement is poured into the inner pile through cement pipes in connecting columns, the cement is input into a first cavity and a second cavity through holes in the outer wall of the inner pile, and the inner pile and an outer pile are fixed; the strength of the inner pile and the outer pile and the pile foundation stability are effectively improved.

Description

technical field [0001] The invention relates to the field of building pile foundations, in particular to reinforced building pile foundations. Background technique [0002] The pile foundation is a deep foundation composed of piles and pile caps connected to the pile tops or a single pile foundation connected by columns and pile foundations, referred to as pile foundations; if the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, then It is called a low-cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high-cap pile foundation; building pile foundations are usually low-cap pile foundations; in high-rise buildings, pile foundations are widely used. [0003] The piles in the existing pile foundation need to be embedded in the soil with a pile driver. Because the pile cannot control the direction of descent, it is easy to be misplaced, and...

Problems solved by technology

[0003] The piles in the existing pile foundation need to be embedded in the soil with a pile driver. Because the pile cannot control the direction of descent, it is easy to be misplaced, and the pile driver needs to drive the pile into the ground for a long time. The pile is embedded in the ground. Because the surface of the pile is smooth and The difference in the hardness of underground soil layers is large, the fitting force of the pile is insufficient, the bearing capacity of the pile is reduced, it consumes manpower and material resources and increases the working time of the project, increases the workload of the workers, and affects the progress of the project
