Building pile foundation and construction process thereof

Abstract

The invention relates to a building pile foundation and a construction process thereof. The building pile foundation comprises a plurality of pile foundation bodies inserted into soil around a pile and a bearing platform arranged at the tops of the multiple pile foundation bodies, wherein each pile foundation body comprises a bottom pile and a top pile located on the bottom pile; a plurality of containing grooves are formed in the top face of each bottom pile; inverted fasteners are arranged in the containing grooves; each top pile comprises a connecting base and an inserting base arranged onthe face, facing the corresponding bottom pile, of the connecting base; the inserting bases are used for driving the inverted fasteners to stretch out of the containing grooves and be inserted into the soil around the pile; the top piles and the bottom piles are fixed through reinforcing assemblies; each pile foundation body is provided with a holding assembly; and the holding assemblies of everytwo adjacent pile foundation bodies are connected through a chain assembly. According to the building pile foundation and the construction process thereof, the inverted fasteners of the pile foundation bodies are inserted into the soil around the pile, the connecting strength of the soil around the pile and the pile foundation bodies is enhanced, and the bearing strength of the pile foundation bodies is improved overall.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a building pile foundation and its construction technology. Background technique [0002] Buildings are built on the ground, which causes the ground to bear a lot of pressure. In order to ensure the stability of the building, the foundation form of ground piles is often used. This form of foundation is widely used in weak soil areas, usually consisting of several The pile foundations in the soil layer jointly support a platform to form the supporting unit of the building. [0003] At present, during the construction of construction piles, it is generally used to drive the prefabricated pile foundation directly into the foundation with a hammering device. Since the pile foundation is basically the same diameter, and the bottom of the pile foundation is set in a pointed cone shape, the pile foundation The area where the bottom transmits pressure to the foundation is small, resulti...

Problems solved by technology

[0003] At present, during the construction of construction piles, it is generally used to drive the prefabricated pile foundation directly into the foundation with a hammering device. Since the pile foundation is basically the same diameter, and the bottom of the pile foundation is set in a pointed cone shape, the pile foundation The area of ​​pressure transmission from the bottom to the foundation is small, resulting in insufficient bearing capacity of the pile foundation, poor stability of the building, and potential safety hazards
