Technical Field

The invention relates to the field of buildings, in particular to a deviation rectifying method for a non-uniform settlement house.

Background

In the construction or use process, people often encounter the phenomenon that the house is unevenly settled due to various reasons (generally, the following reasons are 1, construction measures are not in place, 2, weather reasons such as rainstorm and the like, 3, negative friction resistance is not considered, 4, the foundation condition is complicated but is not clearly investigated before construction, 5, natural disasters such as earthquake, typhoon and the like), so that the house is inclined, and the use function of the house is influenced.

Disclosure of Invention

The invention aims to provide a deviation rectifying method for a non-uniform settlement house, which has the advantages of simple and practical technology, lower cost and convenient construction.

The purpose of the invention is realized as follows:

a deviation rectifying method for a non-uniform settlement house comprises the following steps:

the method comprises the following steps: drilling a row of outdoor grouting holes with the aperture of 75mm and the depth of 2m lower than the depth of a foundation at the position of 2-3m away from the outer wall of the basement of the house on the side with larger settlement of the house, wherein the distance between the outdoor grouting holes and the outdoor grouting holes is 2m, so that the outdoor grouting plugging is realized, and the indoor grouting overflow is prevented;

step two: 15 days after the first step is finished, drilling a row of indoor grouting holes with the aperture of 75mm and the depth of 0.5m lower than the depth of the foundation in the underground chamber on the side with larger settlement of the house, wherein the distance between the indoor grouting holes and the indoor grouting holes is 2m, and realizing indoor grouting to harden the foundation soil;

step three: after 3-5 months after the second step, drilling a row of water injection holes with the diameter of 25mm and the depth of 1.5m lower than that of the foundation in the underground chamber at the position 0.8m away from the outer wall of the underground chamber on the side with smaller settlement of the house, wherein the distance between the water injection holes and the water injection holes is 3.5m, so that the foundation soil is softened by injecting water indoors, and the settlement is accelerated on the side with smaller settlement of the house;

step four: settlement observation points are arranged outdoors on the outer wall of the basement on the side with larger settlement and outdoors on the outer wall of the basement on the side with smaller settlement, settlement observation is carried out on the house through the settlement observation points every day, and grouting amount, grouting depth and water injection amount are adjusted according to observation data so as to correct the deviation degree of the house.

According to the method, through the steps of external grouting plugging, indoor grouting for hardening foundation soil, indoor water injection for softening foundation soil, settlement observation and the like, and through adjustment of grouting amount, grouting depth and water injection amount, settlement is accelerated on the side with smaller settlement of the house, the balance of the house is restored, and correction of the house is realized.

The aim of the invention can also be solved by the following technical measures:

more specifically, the distance between the outdoor grouting hole and the outer wall of the house is 2.5 m.

The invention has the following beneficial effects:

according to the method, through the steps of external grouting plugging, indoor grouting for hardening foundation soil, indoor water injection for softening foundation soil, settlement observation and the like, and through adjustment of grouting amount, grouting depth and water injection amount, settlement is accelerated on the side with smaller settlement of the house, the balance of the house is restored, and correction of the house is realized.
