Construction process of rebuilding durable waterproof layer through space displacement method

Abstract

The invention discloses a construction process of rebuilding a durable waterproof layer through a space displacement method. The construction process includes the steps that a construction surface defect is processed; five grouting holes are drilled in the construction surface, a hollow grouting needle head connected with a feed valve is buried in the grouting hole in the center, and hollow overflow needle heads are connected into the grouting holes in the four corners in a buried mode; epoxy acrylate is injected into the grouting hole through the hollow grouting needle head and serves as back face filler to enhance the back face layer, and then an AHA turbo sealant is injected into the corresponding grouting hole; after slurry overflows from the hollow overflow needle heads, the feed valve is switched off; after the AHA turbo sealant is cured for 24 h, the hollow needle heads are removed, and the grouting holes are blocked. The construction process has the advantages of being simple, saving manpower and energy, protecting environment and saving resources.

Description

technical field [0001] The invention belongs to the technical field of waterproof engineering, and in particular relates to a construction technique for rebuilding a durable waterproof layer by using a space replacement method. Background technique [0002] In recent years, with the rapid development of my country's construction industry, residential buildings and various shopping mall projects are increasing. During the rapid development of these construction projects, the problem of water leakage in kitchens, bathrooms, and public toilets in shopping centers has become increasingly prominent; Although a waterproof layer was installed during the initial construction process, due to improper construction of the waterproof layer, thermal expansion and contraction caused gaps between building constructions, etc., water seepage and channeling occurred in the floors and walls of the building. For the above-mentioned problems such as leakage and water channeling, the bathroom or k...

Problems solved by technology

[0003] The above-mentioned conventional repair method has the following disadvantages: 1. The process is cumbersome, time-consuming and labor-intensive. It will waste a lot of manpower to smash the paved indoor floor tiles or basement concrete floors, and it will use high-power electric picks, which will It consumes a lot of electricity and does not comply with environmental protection policies; 2. It causes a waste of resources. Whether it is to re-make the waterproof layer indoors or find the source of leakage in the basement to block it, the ground must be re-paved after the end, which is not only expensive. Manpower is a waste of resources; 3. When doing secondary waterproofing, it is difficult to combine the old and new waterproof layers well, and the new waterproof layer is prone to secondary leakage, which cannot fundamentally solve the problem.
