Construction method of building pile foundation

Abstract

The embodiment of the invention discloses a construction method of a building pile foundation. The construction method comprises the steps that pile foundation areas are selected; pile holes are rotatably excavated; a pile body reinforcement cage is hoisted in each pile hole, underwater concrete is poured by adopting a conduit method, and standing is performed to form a pile; after the pile bodiesare completely formed, a pouring space is horizontally dug around all the pile bodies in each pile foundation area; a plurality of rubber cylinders are evenly placed in the pouring space, cylindricalstructural bodies used for reducing the shattering degree of the pile bodies are placed in the rubber cylinders, concrete is poured outside the rubber cylinders, soil is poured into the rubber cylinders, and an anti-shattering pouring body is formed; the anti-shattering pouring body is filled with the horizontally excavated material and compacted, and finally a low pile bearing platform is formedat the tops of the pile bodies. By means of the technical scheme, when the vibration force is too large, pressure buffering can be achieved through matched arrangement of the rubber cylinders and thecylindrical mechanism body, all holes in the rubber cylinders are filled with the soil, and the stable effect of the whole structure is further guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of building pile foundation construction, in particular to a construction method for building pile foundations. Background technique [0002] Building pile foundation is a kind of deep foundation that connects several piles into a whole through caps, and jointly bears dynamic and static loads. It is the foundation work in construction engineering. It can not only ensure the quality of construction projects, but also plays a decisive role in the stability and safety of the entire building. [0003] Nowadays, with the continuous development of technology, the height of buildings is getting higher and higher, and the sense of vibration is becoming more and more obvious. In the case of a relatively stable environment, building pile foundations can meet the needs of actual use. However, once geological disasters and other situations occur, the existing building pile foundations are ofte...

Problems solved by technology

However, once geological disasters and other situations occur, the existing building pile foundations are often difficult to meet the demand, and when the pile foundations are damaged and collapsed, as the height of the floor increases, the collapse time of the floor will be greatly reduced, and then greatly Reduce the probability of escape
