Abstract

The invention discloses a deep foundation treatment method and a foundation structure, relates to the technical field of foundation treatment, and solves the problem of poor overall stability of support piles in the prior art. In the present invention, the bottom ends of the adjacent support piles are connected as a whole through connecting piles to form a three-dimensional network structure, which enhances the overall stability of the support piles. When the foundation is subjected to lateral or longitudinal vibrations, the support piles will not Deformation or even dislocation occurs to avoid damage to the superstructure; by setting multiple through holes for auxiliary grouting on the periphery of the grouting pipe, the outlet of the grouting pipe and the through hole are grouted at the same time, and the first drill pipe can be drilled. When exiting the inclined hole, quickly fill the inside of the inclined hole with cement slurry to avoid collapse; by making the expansion head, even if one of the connecting piles is slightly offset, it can ensure that the two connecting piles are connected as a whole through the expanding head to avoid connection The piles are dislocated and not connected as a whole, which improves the overall stability of the supporting piles.

Description

technical field

[0001] The invention relates to the technical field of foundation treatment, more specifically, it relates to a deep foundation treatment method and a foundation structure. Background technique

[0002] In order to improve the bearing capacity of the foundation soil and reduce the foundation settlement or soil permeability of the building, the foundation soil needs to be treated. Common methods for foundation deep treatment include cement-soil mixing pile method, grouting method, and rotary jetting pile method. The three soil reinforcement methods are all operated point by point on the ground of the reinforced soil in a vertical manner.

[0003] Publication No. CN105714773A discloses a ground treatment method in the Chinese invention patent, which specifically includes the following steps: (1) sinking pipe: sinking the steel pipe and the pile point abutting against the lower end surface of the steel pipe together by using a vibrating pile pulling machine int...
