Abstract

The invention discloses a building pile foundation, and relates to the technical field of buildings. The building pile foundation comprises a pile foundation outer frame, wherein a spiral outer frameis mounted on the inner wall of the pile foundation outer frame, the spiral outer frame penetrates through the pile foundation outer frame, a mounting groove matched with the spiral outer frame is formed in the outer side of the pile foundation outer frame, a soil rotating cutter is slidably connected to the interior of the spiral outer frame, and the two ends of the soil rotating cutter extend tothe outer part of the spiral outer frame. According to the building pile foundation, the contact area of metal reinforcing rods installed in the pile foundation and poured cement can be increased, the firmness degree of the pile foundation is increased, the pile foundation can be placed into a foundation pit while the foundation pit is dug, the pile foundation landfill step is reduced, the pile foundation construction efficiency is improved, the foundation pit digging difficulty is reduced, the foundation pit with the same size as the pile foundation can be dug out properly without considering the size adaptation problem of the foundation pit and the pile foundation, the pile foundation can be fixed conveniently after being placed in the foundation pit, and the workload of pre-digging thefoundation pit is reduced.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction pile foundation. Background technique [0002] The building pile foundation is used to drive into the building ground, and the interior is cemented, and the supporting pile body is formed after the cement dries. The current building pile body is generally a hollow structure, and the hollow structure is composed of more than one piece. The substrates are spliced ​​together, and then the cavities formed by splicing are poured with cement. [0003] Chinese invention CN109137890A discloses a building foundation pile, which includes a frame-shaped hollow foundation pile spliced ​​by four base plates. There is a square pouring cavity in the middle of the foundation pile, and the bottom of the four base plates can be destroyed. A hollow plate is fixedly installed on the inner side of the four base plates. There is a hollow hollow cavity inside the hollow plate. More...
