Construction technology for reconstructing durable waterproof layer by using minimally invasive method

Abstract

The invention discloses a construction technology for reconstructing a durable waterproof layer by using a minimally invasive method. Firstly, defects of a construction surface are treated; 2-8 grouting holes are formed per square meter of the construction surface, and hollow needles connected with feed valves are embedded in the grouting holes in a connection mode; secondly, epoxy acrylate is injected in the grouting holes to serve as a back-surface filling agent to reinforce a back-surface layer, and an AHA turbine sealant is injected in the grouting holes; after the AHA turbine sealant overflows from the hollow needles in every two adjacent grouting holes, the feed valve on the previous hollow needle is closed, and then the AHA turbine sealant is injected again in the hollow needles where the AHA turbine sealant overflows until all the feed valves are in a closed state; after the AHA turbine sealant is cured for 24 hours, the hollow needles are removed, and the grouting holes are blocked off. The construction technology has the following advantages that the process is simple, labor is saved, energy conservation and environmental protection are achieved, and resources are saved.

Description

technical field [0001] The invention belongs to the technical field of waterproof engineering, and in particular relates to a construction technique for recreating a durable waterproof layer by using a minimally invasive method. Background technique [0002] In recent years, with the rapid development of my country's construction industry, residential buildings, various shopping centers, underground comprehensive pipe corridors, and tunnel engineering projects are increasing. During the rapid development of these civil engineering projects, residential floors, basement walls, tunnels The problem of water leakage on walls and pipe gallery walls has become increasingly prominent; although waterproof layers were installed in the initial construction process, due to improper construction of the waterproof layer, thermal expansion and contraction caused gaps between building constructions, etc., the floor slabs in the building , water seepage, water channeling and other problems in...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned conventional repair methods have the following disadvantages: 1. The process is cumbersome, time-consuming and labor-intensive. A large amount of manpower will be wasted if the paved indoor floor tiles or basement concrete floors are smashed, and high-power electric picks will be used. A large amount of electric energy 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 labor-intensive , which is a waste of resources; 3. For underground pipe galleries and tunnels, repairing cracks can only solve the temporary water seepage problem, and cannot fundamentally solve the problem of seepage at one time. Severe leakage will not be able to effectively solve the fundamental water seepage problem in the end
