Grouting stoppage and guide repair method for leakage of deformation joint and special grouting device for grouting stoppage and guide repair method for leakage of deformation joint

Abstract

The invention discloses a grouting stoppage and guide repair method for leakage of a deformation joint and a special grouting device for the grouting stoppage and guide repair method for the leakage of the deformation joint. The construction comprises the following steps of: clearing the deformation joint; arranging a grouting hole; inserting a grouting pipe; mixing and grouting; removing rapid hardening mud; and installing a stoppage and guide strip. The special grouting device can ensure reasonable ratio of glue solution and water; the mixing and grouting pipe can be used for mixing the synchronously pressed-in glue solution and water before the grouting, so that the mixed liquor can rapidly take reaction to generate a new water stoppage layer in soft puddle shape after being subjected to the grouting, and one-level effective leakage stoppage can be realized; the stoppage and guide strip is installed at the outer side opening of the deformation joint in a sealing way to realize secondary leakage stoppage and leakage guide for the deformation joint, even if trace leakage exists in the deformation joint, trace permeated water is also guided to an underground drainage system, and no influence is caused on normal use of a basement. The repair method provided by the invention not only can thoroughly solve the leakage of the deformation joint, but also is simple in operation, lower in cost and strong in practical applicability.

Description

【Technical field】 [0001] The invention relates to a method for repairing leakage from deformation joints of underground building walls. 【Background technique】 [0002] In underground buildings, the walls are all concrete structures. According to the design requirements, deformation joints (commonly known as expansion joints) must be set when the length of the building reaches a certain distance. In order to prevent leakage at the deformation joints, the deformation joints must be filled with asphalt The glue composed of hemp silk, after it is cooled and solidified, fills the deformation joint. In order to prevent the filler from expanding out of the joint, a rubber water retaining plate composed of a circular tube body and a side plate is usually added to the exposed part of the deformation joint. The decorative board is used outside the rubber water retaining board to beautify and decorate the wall, thereby further improving the anti-leakage performance. The anti-leakage s...

AI Technical Summary

Problems solved by technology

However, the leakage conditions in the deformation joints are different, and the mixing ratio of glue and water cannot be guaranteed, and the glue and water can not be mixed evenly before grouting, which directly affects the performance of the new leakage blocking layer after grouting. Formation and solidification, it is difficult to guarantee the sealing effect. Although this repair method can meet the acceptance, it will still leak after a long time, and will find the construction unit. Therefore, Party A will withhold the construction unit's project payment. This is the construction The industry is very troublesome technical problems
