Problems solved by technology

[0006] The above method and the existing leakage repair method need to destroy the wall or the bottom plate in a large area to expose the damaged waterproof layer, and then set a new waterproof layer. After the completion, the backfill soil needs to be backfilled again, so the operation is complicated and the construction period is long. Long, large amount of material

Embodiment 1

[0030] A method for rebuilding a waterproof layer with a minimally invasive technique, the scheme of which is:

[0031] Step 1. Seal the cracks, clean up the cracks on the building surface that need to be repaired, and then seal the cracks with fast-curing mortar;

[0032] Step 2: Drill holes, drill grouting holes on the building surface that needs to be repaired, the number of holes to be drilled is 4 pcs / m 2 , and bury the grouting needle in the grouting hole;

[0033] Step 3: Inject the filler, inject the back filler from the grouting hole, and prepare the back filler according to the following method:

[0034] Stir and mix 20kg methacrylic acid, 10kg styrene, 15kg castor oil maleate and 0.1kg diallyl bisphenol A, then add 0.8kg initiator, stir and mix evenly, slowly add to 30kg butyl glycol In the ether, control the addition within 30 minutes, control the temperature to 90°C and react for 3 hours. After the reaction is completed, add 15.6kg of expanded perlite, 10.2kg of...

Abstract

The invention relates to the field of building repairing, and particularly relates to a method for reconstructing a waterproof layer through a minimally invasive technology. The method comprises the steps of crack blocking, punching, filling agent injection, waterproof sealant injection, grouting hole blocking and the like. According to the method, a back filling agent and a waterproof sealant are injected into a building wall through a drilling injection method, and the purpose of reconstructing the waterproof layer is achieved. The invention provides a preparation method of the back filling agent and the waterproof sealant. The two materials are moderate in viscosity and suitable for injection filling, good bonding performance is achieved between the two materials, and excellent waterproof performance is achieved after complete curing. The method for reconstructing the waterproof layer is simple in operation procedure, materials and manpower are saved, damage to original wall decoration is very small, the construction period is short, and the problems of leakage and water channeling can be efficiently and rapidly solved.

Description

technical field [0001] The invention relates to the field of building repairs, in particular to a method for rebuilding a waterproof layer with a minimally invasive technique. Background technique [0002] With the increase in the number of high-rise buildings, basements are generally designed in the design of urban buildings now. Considering the safety of the building structure, the depth of the building buried in the ground will also increase, the depth and number of floors of the basement, and the number and types of basement projects will also increase. Most buildings are now reinforced concrete structures. Once the concrete cracks, the moisture that enters is not just as simple as penetrating into the room. What's more serious is that moisture will corrode the steel bars inside the concrete, which will have a very serious impact on the entire building structure. The worst result is to greatly reduce the bearing capacity of the building, so the problem of waterproofing ...
