Inclination rectification and reinforcement method for existing building

Abstract

The invention discloses an inclination rectification and reinforcement method for an existing building. The method specifically comprises the following steps: firstly, drilling vertical small holes in a relatively large depression area, grouting and reinforcing; secondly, vertically drilling in a medium depression area and a relatively small depression area and taking out soil from a deep layer to perform inclination rectification; thirdly, forming grooves by excavating the sides of base bearing platforms of the medium depression area and the relatively small depression area, horizontally drawing out soil to perform inclination rectification in the base of the bottom of each base bearing platform; fourthly, downwards drilling each base bearing platform to form a small hole until the small hole reaches a rock stratum, arranging an H-shaped steel or small steel reinforcement cage in the hole, and grouting the hole; finally reinforcing the base by adopting an overall plate. The method disclosed by the invention is capable of reasonably and effectively controlling settlement and inclination degree of a house and preventing excessive inclination rectification caused by drilling and soil picking during the inclination rectification process.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a rectification and reinforcement method for an existing building. Background technique [0002] The so-called building rectification refers to the use of appropriate rectification technology, supplemented by foundation reinforcement technology, to straighten the tilted building to the limit required for normal use, so as to ensure the safety of the building structure and the normal function of the building. [0003] After years of engineering practice and theoretical research, great progress has been made in various aspects of building rectification at home and abroad. With the in-depth study of the properties of soil, people have in-depth understanding of the causes and laws of uneven settlement of buildings. However, most of the theoretical achievements based on the rectification methods are still in soil mechanics, engineering geology and foundati...

AI Technical Summary

Problems solved by technology

Moreover, the construction sequence of most rectification methods is not clear, and the method is relatively complicated, which leads to failure of rectification or high cost of rectification and reinforcement

In order to ensure the safety of the structure, rectification and reinforcement should disturb the surrounding soil as little as possible, so as to avoid the aggravation of uneven settlement. If there is no reasonable construction method, it is difficult to solve this problem
