Settlement prevention foundation structure for soft soil foundations and method thereof

Abstract

The invention discloses a settlement prevention foundation structure for soft soil foundations and a method thereof and relates to the technical field of building construction. According to main points of the technical scheme, the foundations are included, and multiple sets of settlement prevention devices arranged in the foundations are further included; each set of settlement prevention device comprises an installing hole, a connection barrel arranged in the installing hole, and a plurality of through holes evenly distributed in the peripheral face of the connection barrel in the circumferential direction of the connection barrel, wherein an abutting plate is slidably connected in each through hole in the radial direction of the connection barrel, an elastic assembly used for limiting the abutting plate is installed at the bottom of the connection barrel, a cylindrical push rod used for pushing the abutting plate to move is arranged in the connection barrel, an inwards concave firstcambered face is arranged at the end, close to the push rod, of the abutting plate, an outwards convex second cambered face is arranged at the other end of the abutting plate, the first cambered faceabuts against the peripheral face of the push rod, a circular truncated cone block is arranged at the bottom end of the push rod, and a driving mechanism used for driving the push rod to move is arranged on the foundations. The settlement prevention devices are arranged so that the possibility of settlement of the foundations can be lowered.

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.
