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 reconstructing a waterproof layer with a minimally invasive technique, the scheme is as follows:

[0031] Step 1: Block the cracks, clean up the cracks on the building surface that needs to be repaired, and then use the quick-curing mortar to seal up the surprise of the cracks;

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

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

[0034] With 20kg methacrylic acid, 10kg styrene, 15kg ricinoleate maleate and 0.1kg diallyl bisphenol A, add 0.8kg initiator after stirring and mixing, slowly add 30kg ethylene glycol butyl after stirring and mixing Add 15.6kg of expanded perlite, 10.2kg of mica powder, 3.2kg of expanded rubber powder and 1.5kg of carbon black powder into the reaction kettle after co...

Embodiment 2

[0043] A method for reconstructing a waterproof layer with a minimally invasive technique, the scheme is as follows:

[0044] Step 1: Block the cracks, clean up the cracks on the building surface that needs to be repaired, and then use the quick-curing mortar to seal up the surprise of the cracks;

[0045] Step 2: Drill holes, drill grouting holes on the building surface to be repaired, and the number of holes is 6 / m 2 , and bury the grouting needle in the grouting hole;

[0046] Step 3, inject filler, inject back filler from the grouting hole, and the back filler is prepared according to the following method:

[0047] After stirring and mixing 25kg methacrylic acid, 13kg styrene, 18kg ricinoleate maleate and 0.3kg diallyl bisphenol A, add 1kg initiator, slowly add 40kg butyl glycol ether after stirring and mixing control the temperature to 100℃ for 4h, after the reaction is completed, add 22.4kg expanded perlite, 13.6kg mica powder, 4.8kg expanded rubber powder and 2.5kg ca...

Embodiment 3

[0056] A method for reconstructing a waterproof layer with a minimally invasive technique, the scheme is as follows:

[0057] Step 1: Block the cracks, clean up the cracks on the building surface that needs to be repaired, and then use the quick-curing mortar to seal up the surprise of the cracks;

[0058] Step 2. Drill holes, drill grouting holes on the building surface to be repaired, and the number of holes is 8 / m 2 , and bury the grouting needle in the grouting hole;

[0059] Step 3, inject filler, inject back filler from the grouting hole, and the back filler is prepared according to the following method:

[0060] With 30kg methacrylic acid, 15kg styrene, 22kg ricinoleate maleate and 0.5kg diallyl bisphenol A, add 1.2kg initiator after stirring and mixing, slowly add 50kg ethylene glycol butyl after stirring and mixing Add 32.2kg expanded perlite, 16.6kg mica powder, 6.8kg expanded rubber powder and 4.5kg carbon black powder to the reaction kettle after the reaction is ...

Abstract

The invention relates to the field of building repairs. A method for rebuilding a waterproof layer with a minimally invasive technique of the invention includes the steps of sealing cracks, punching holes, injecting fillers, injecting waterproof sealants, and plugging grouting holes; The method of drilling injection injects the back filler and waterproof sealant into the interior of the building wall to achieve the purpose of reshaping and rebuilding the waterproof layer; the invention provides a preparation method for the back filler and waterproof sealant, and the viscosity of the two materials It is moderate, suitable for injection filling, and has good bonding performance between the two materials, and has excellent waterproof performance after complete curing; the operation procedure of the waterproof layer reconstruction method of the present invention is simple, saves materials and manpower, and saves on the original Some wall decorations are very less destructive and have a short construction period, which can efficiently and quickly solve the problems of leakage and water channeling.

Description

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