Abstract

The invention discloses a high-rise deviation-rectifying static pressure anchor rod pile and broken pile underpinning supporting device and a monitoring method thereof. More static pressure anchor rod pile reinforcing structures are arranged on the side with large settlement displacement, a small number of static pressure anchor rod pile reinforcing structures and broken pile underpinning jack structures are arranged on the side with small settlement displacement, an original pile foundation, the static pressure anchor rod pile reinforcing structures and the broken pile underpinning jack structures jointly underpin and support an original inclined high-rise building on a basement floor structure, and through lifting adjustment of underpinning jacks, deviation-rectifying construction of the inclined high-rise building is conducted. A broken pile underpinning deviation-rectifying construction real-time monitoring system receives wireless transmission data information of a GPS automatic deviation-rectifying displacement monitoring system and a structural stress strain monitoring network system, parameters of a finite element calculation model are corrected, a reasonable deviation-rectifying construction scheme is formulated, the broken pile underpinning deviation-rectifying construction real-time monitoring system commands forced landing displacement numerical values of the jacks of the underpinning jack structures, and deviation-rectifying construction of the inclined high-rise building is electronically monitored.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a high-rise deflection correcting static pressure anchor pile and broken pile underpinning supporting device and a monitoring method thereof. Background technique [0002] Due to the design and construction of pile foundations of high-rise buildings, accidents of insufficient bearing capacity of pile foundations, excessive settlement of foundations and uneven settlement have occurred frequently, resulting in the inclination of high-rise buildings. After the high-rise building is tilted, due to the high center of gravity of the structure of the high-rise building, its structural center of gravity is unstable, and the inclined high-rise building will generate a secondary additional bending moment on the foundation, which will further aggravate the uneven settlement of the high-rise building. The acceleration of the tilting rate of objects will lead to cracking of the su...

AI Technical Summary

Problems solved by technology

[0004] In the existing deflection rectification project of high-rise buildings, the deflection rectification of the building is carried out by the forced landing method or the lifting method. During the deflection rectification construction process, it is only through the settlement monitoring, tilt monitoring and crack monitoring outside the building to judge whether the rectification process is reasonable and effective. , the whole process of deviation correction operation basically relies on artificial eyesight and experience, and requires technicians with very experience in deviation correction engineering to operate. Such deviation correction construction cannot effectively control high-rise buildings in a structurally safe state, and the structural safety during deviation correction construction is poor. high accident rate
