A kind of parapet wall seepage water repair technology

Abstract

This application relates to a parapet water leakage repair process, comprising the following steps: S1, excavating the root of the parapet wall and the ground to the structural layer; S2, coating a waterproof layer on the walls of the horizontal construction groove and the vertical construction groove, Then attach the waterproof coiled material above the waterproof layer; S3, lap the waterproof sheet on the horizontal groove wall of the lap groove, press the waterproof sheet to the position where the waterproof coil is located in the overlap groove, and make the waterproof skirt tight The waterproof coiled material is located at the position of the vertical construction groove; a grouting tank is formed between the waterproof sheet and the waterproof coiled material; S4, inject slurry into the grouting tank through the grouting channel until the last grouting channel flows out Slurry; S5. Seal the tight side of the waterproof sheet and the waterproof membrane, and finally coat the surface of the waterproof sheet and the exposed waterproof membrane with a protective surface layer. The application can not only well repair the water seepage part of the parapet wall, but also has high construction efficiency.

Description

technical field [0001] The present application relates to the field of building restoration, in particular to a technique for repairing water leakage in a parapet wall. Background technique [0002] The parapet is the low wall around the roof of the building. The parapet can not only protect the safety of personnel, but also play a decorative role on the facade of the building, and can also prevent the rainwater from overflowing on the roof; but the parapet often affects its use because of cracking. After the wall is cracked, it will form a leaking channel, which will make the water flow bypass the waterproof layer of the parapet wall and invade the roof insulation layer, which will not only make the roof saturated with water in a large area, but also leak into the room after spreading in a large area, affecting people's health. Normal life. [0003] The Chinese patent with the application number CN201810065107.2 discloses a parapet wall leakage repair process, which includ...

Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that whether it is the painting of waterproof paint, the pasting of waterproof coiled materials, or the pouring of crushed stone concrete, it is necessary to reduce the generation of gaps and cavities as much as possible, so as not to affect the subsequent waterproof effect, so The construction workers must be pressed layer by layer, which is very laborious and the construction efficiency is low
