Foundation Structure and Method for Anti-Settlement of Soft Soil Foundation

Abstract

The invention discloses a subsidence-proof foundation structure and method for a soft soil foundation, and relates to the technical field of building construction. It includes a mounting hole, a connecting cylinder arranged in the mounting hole, and a plurality of through holes evenly distributed on the outer peripheral surface of the connecting cylinder along the circumferential direction of the connecting cylinder; each through hole is slidingly connected with an abutment plate along the radial direction of the connecting cylinder, and the connection The bottom of the cylinder is equipped with an elastic component for limiting the abutment plate; a cylindrical push rod for pushing the abutment plate to move is arranged in the connecting cylinder, and the end of the abutment plate close to the push rod is provided with a concave first Arc surface, the other end of the abutment plate is provided with an outwardly convex second arc surface, the first arc surface abuts on the outer peripheral surface of the push rod; the bottom end of the push rod is provided with a round platform block, and the foundation is provided with a the drive mechanism. The present invention can reduce the possibility of foundation subsidence by setting the anti-subsidence device.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, it relates to a subsidence-preventing foundation structure for soft soil foundations and a method thereof. Background technique [0002] With the acceleration of urbanization, the construction of civil engineering is increasing, and the phenomenon of soft soil foundation is becoming more and more common. If the foundation soil is soft soil, its bearing capacity and shear resistance are weak, especially when it is subjected to vibration or a large load, the strength of the foundation will decrease obviously, and it will be in a flowing state, which will cause local or overall shearing of the foundation. Destroyed, forming soft soil layer side slip. [0003] In the process of large-area soft soil foundation treatment, drainage channels are usually used to improve soil strength and reduce soil settlement. Cushion treatment technology, commonly known as cushion meth...

Problems solved by technology

[0004] However, due to the discharge of the above-mentioned foundation, the effective stress of the foundation will increase, and the foundation will generally settle, so it may be necessary to lay a cushion layer to increase the height of the foundation.
