Foundation structure and construction method

Abstract

The invention is applicable to the technical field of geotechnical engineering and provides a foundation structure and a construction method. The foundation structure comprises a foundation body, a bearing platform, a first supporting pile and a plurality of second supporting piles, wherein the foundation body is arranged in a construction site; the bearing platform is arranged in the constructionsite and is connected to the bottom of the foundation body; one end of the first supporting pile is inserted into the soil body in a manner of being perpendicular to the surface of the construction site; the other opposite end is connected with the bearing platform; all second supporting piles are arranged in a spaced manner; one end of each second supporting pile is obliquely inserted into the soil body in a manner of forming an included angle with the surface of the construction site; and the opposite other end of each second supporting pile is connected with the bearing platform, wherein the first supporting pile and the second supporting piles are each internally provided with a cavity and are also each provided with a grout spraying hole communicating with the corresponding cavity. In the foundation structure provided by the invention, the first supporting pile and the second supporting piles form a tree root-like structure to improve the bearing capacity and the toppling resistance of the foundation structure; the soil body is filled with a grout material via the grout spraying holes; the physical and mechanical properties of the soil body are improved; and safety guaranteeis provided for a built structure.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to a foundation structure and a construction method. Background technique [0002] The independent foundation and the strip foundation belong to the shallow foundation type, and this type of foundation can be buried in strata with good geological conditions, high physical and mechanical properties of the foundation soil, and large bearing capacity. However, when it is necessary to build a foundation on a soil with poor physical and mechanical properties and a large soil layer thickness, this type of shallow foundation cannot meet the requirements for use. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a foundation structure and a construction method to solve the problem of building a foundation on a soil with poor physical and mechanical properties and a thick soil layer. [0004] In order to solve...
