High-strength anchor net mortar pouring, reinforcing, leaking stoppage and repairing method for underground structure leakage

Abstract

The invention discloses a high-strength anchor net mortar pouring, reinforcing, leaking stoppage and repairing method for underground structure leakage. According to the high-strength anchor net mortar pouring, reinforcing, leaking stoppage and repairing method for underground structure leakage, on the basis that roughening is carried out on a leakage surface, blocking is carried out on large-strand water flow through drainage, grouting and the like; short anchor bolts are arranged in a structure leakage area according to a certain row spacing and depth; a steel wire mesh is arranged, and fixing the steel wire mesh and the anchor bolts together is carried out; compact mortar with certain slump is prepared, and a proper amount of anti-crack fiber is added; and mortar materials are distributed in the leakage area, vibration pouring is carried out through template fixing, gas in the mortar is exhausted, and the compactness of the mortar is improved. Thus, after the mortar is solidified to form strength, a high-strength compact flexible mortar waterproof anchoring layer is formed on the structure leakage inner surface, and a seepage channel is permanently blocked; so that the whole leakage treatment time is short, the manufacturing cost is low, and the extremely important application and popularization value is achieved.

Description

technical field [0001] The invention belongs to the field of structural waterproofing engineering, and relates to a leaking high-strength anchor net mortar pouring reinforcement plugging repair method for underground structures. Background technique [0002] Underground structural engineering has the characteristics of large construction area, wide scope, large embedding depth, and high construction technology requirements. It is particularly difficult to control the structural leakage problem. In general, the waterproofing of underground structures adopts the principle of "combination of rigidity and flexibility, multiple fortifications", among which the self-waterproofing of structural concrete is the main one. In view of the high compressive strength and low tensile strength of the concrete structure, during the pouring process, it is very easy to cause shrinkage cracks, coupled with the damage or discontinuity of waterproof materials, improper handling of construction jo...

AI Technical Summary

Problems solved by technology

[0004] (2) Quality problems of structural pouring

During the pouring process of concrete structures, due to untimely supply of raw materials and improper distributing methods, etc., "cold joints" and insufficient pouring and vibration are prone to occur, forming non-dense areas inside the concrete, and large areas of wet stains and open water leakage;

[0005] (3) Conservation issues

[0006] (4) Structural force problem

[0011] At present, after the leakage of the underground structure, there are generally many ways to repair it by grouting, but repeated leakage will occur in a short period of time

Finally, drainage is mostly done by setting intercepting ditches. There is still no good implementation method for the radical cure of seepage prevention in the world.
