Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail by combining the embodiments and the drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. The following describes the technical scheme of the present utility model in detail with reference to examples and drawings, but the scope of protection is not limited thereto.

Referring to fig. 1 to 3, the present embodiment proposes a building foundation pile comprising a foundation pile body 1, an adjusting base 2, a counterweight base 3 and a supporting frame 4; specifically, the foundation pile body 1 is an existing pile body to be driven into the building ground; the adjusting base 2 comprises a left base 21 and a right base 22 which are arranged in parallel, the left base 21 and the right base 22 are steel members with cylindrical structures, a connecting hole is formed in the center of the left base 21 and the center of the right base 22, a rotating shaft 5 horizontally penetrates through and is fixedly connected with the position, close to the top, of the foundation pile body 1, and two ends of the rotating shaft 5 are respectively connected with the left base 21 and the right base 22 in a rotating mode through bearing groups; the foundation pile body 1 is rotatable with respect to the left and right bases 21 and 22.

The tops of the left base 21 and the right base 22 are both connected with a hoisting mechanism. The hoisting mechanism is a hoisting hook 8 and is used for hoisting the adjusting base 2 and the foundation pile body 1 together. When the left and right bases 21 and 22 are lifted, the pile body 1 is maintained in a vertical state by gravity. In order to strengthen the vertical state, the bottom of the foundation pile body 1 is connected with the counterweight base 3, and the counterweight base 3 is of a cone structure, so that the weight of the bottom of the foundation pile body 1 can be further increased, and the foundation pile body is kept in the vertical state.
