Repairing process for water leakage of parapet wall

Abstract

The invention relates to a repairing process for water leakage of a parapet wall. The repairing process comprises the following steps that S1, the wall root of a parapet wall body and the ground are excavated to a structural layer; S2, the groove walls of a horizontal construction groove and a vertical construction groove are coated with waterproof layers, and then waterproof coiled materials adhere to the upper portions of the waterproof layers; S3, a waterproof plate is in lap joint with the horizontal groove wall of a lap joint groove, the waterproof plate is pressed against the positions, located in the lap joint groove, of the waterproof coiled materials, a waterproof skirt edge abuts against the positions, located in the vertical construction groove, of the waterproof coiled materials, and a grouting groove is formed between the waterproof plate and the waterproof coiled materials; S4, slurry is injected into a grouting groove through slurry passing through grooves until the slurry flows out of the last slurry passing through groove; and S5, the abutting side of the waterproof plate and the waterproof coiled materials is sealed, and finally the surface of the waterproof plate and the exposed surfaces of the waterproof coiled materials are coated with protective surface layers. According to the repairing process, the water leakage part of the parapet wall can be well repaired, and the construction efficiency is high.

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
