A kind of horizontal repair hole wall protection method of house wall

Abstract

A wall protection method for a horizontal repair hole in a wall of a house, comprising the following steps: a. sending a drill pipe into the repair hole where the wall has been drilled; b. injecting wall protection slurry into the horizontal hole; c. coating the hole wall with the wall protection slurry; d. The retaining rods are left in the transverse holes, and the retaining wall layer is composed of the retaining wall slurry layer and the retaining rods. On the one hand, the method of the invention can effectively prevent grout from seeping out and contaminating the wall during the grouting and anchoring process, and on the other hand, can greatly improve the strength of the repair hole, thereby effectively improving the overall repair strength of the brick masonry wall. The wall protection slurry provided by the invention has the characteristics of high viscosity, good anti-seepage performance, good cohesiveness, easy curing, high consolidation strength, etc., and solves the problem of easy leakage of conventional grouting.

Description

technical field [0001] The invention relates to a method for repairing a house, in particular to a method for protecting a wall in a horizontal repair hole of a house wall. Background technique [0002] In the repair and reconstruction project of old houses, it is often necessary to penetrate steel bars or reinforcing beams in the walls of the houses to reinforce the walls, so as to improve the safety of the old houses and prolong the service life. The wall repairing process first needs to drill horizontal repair holes (ie holes along the extension direction of the wall) on the wall to be repaired. After completing the horizontal drilling in the wall, the wall is then grouted and anchored with steel bars or steel tie rods. The problem with this traditional construction method is that some old houses have thin walls and brick masonry, which has low impermeability. The brick masonry has gaps and pre-buried pipelines or existing leaks. In the process, it will often cause the l...

AI Technical Summary

Problems solved by technology

The problem of this traditional construction method is that some old houses have thin walls and brick masonry, which has low impermeability. The brick masonry has gaps and pre-buried pipelines or existing leaks. It will often cause the leakage and running of the grouting slurry, so that the surface of the wall of the house, especially the built-in wall, will be stained.

This problem is especially prominent for the repair of old houses with cultural relics. Once the grouting slurry leaks to the wall surface, it will cause irreparable losses to the cultural relics houses.

In addition, the walls of some old houses are severely pulverized, and the strength of the transverse holes punched is insufficient, which seriously affects the effect of grouting and anchoring through steel tie rods.
