Problems solved by technology

This problem has always been a common problem in the quality of construction projects, which has brought great troubles to people's lives.
For the waterproof treatment of basement side wall cracks, grouting and waterproof coating are generally adopted, but the effect achieved is not ideal. The main reasons are: 1) The method of grouting cannot achieve long-term plugging effect, because the concrete slab will As time changes under the action of internal stress and external force, the cracks of the concrete slab will also change, and the original grouting will lose its effect after the cracks change
2) The method of applying waterproof coating is firstly that the coating film formed by waterproof coating itself lacks toughness, and the bonding performance between the coating film and the concrete surface also directly affects the plugging effect

Embodiment 1

[0037] A basement outdoor wall crack waterproof treatment device, comprising:

[0038] A fixing mechanism installed on a wall structure, the fixing mechanism includes three straps 1 arranged outside the pressurized sealing mechanism, and self-tapping screws 2 installed at the ends of the straps 1 and connected with the wall structure.

[0039] The pressurized sealing mechanism installed on the inner side of the cuff and covered on the periphery of the crack, the pressurized sealing mechanism includes a pressurized protective cover 3 fixedly installed with the cuff 1, painted on the periphery of the crack and connected with the pressurized protective cover 3 The polyurethane coating corresponding to the position, this layer of polyurethane coating is used to seal the gap between the pressurized protective cover 3 and the wall structure to prevent pressure leakage, and the flexible spacer 4 arranged inside the pressurized protective cover 3, The flexible spacer 4 divides the pre...

Embodiment 2

[0042] Embodiment 2: A method for sealing cracks of a basement outdoor wall crack waterproof treatment device, comprising the following steps:

[0043] S1: Apply polyurethane coating on the periphery of the crack, set the pressurized protective cover 3 on the outside of the crack, and fix the pressurized protective cover 3 and band 1 with self-tapping screws 2, and paint on the cracks on the inner wall of the wall structure plugging king;

[0044] S2: injecting waterproof and weather-resistant glue into the interior of the flexible spacer 4 through the glue injection nozzle 8 and pressing it into the crack under its pressure;

[0045] S3: Pressurize the glue part 5 through the pressurizing nozzle 7, apply the internal pressure of the pressurizing part to the flexible spacer 4, and press the waterproof and weather-resistant glue inside the flexible spacer 4 into the crack.

[0046] Wherein, the waterproof and weather-resistant adhesive press-in process in the S2 step includes: ...

Embodiment 3

[0051] Embodiment 3: A waterproof treatment device for cracks in the outdoor wall of a basement, including a blind installation hole 9 obliquely opened on the wall structure. The blind installation hole 9 runs through the crack and a pressure grouting mechanism is embedded in the hole. The grouting mechanism includes a fixing part 10, an adjusting part 11 and a tensioning part 12. The fixing part 10 is a hollow structure and one end is provided with a fixed plate 13. Outside the fixing part 10 and between the adjusting part 11 and the fixing plate 13 , the tensioning part 12 includes a moving part 14 and an elastic blocking part 15 integrally connected. Through the adjustment member 11 (preferably a nut), the adjustment member 11 moves to the side close to the fixed plate 13 and squeezes the tension member 12, so that the elastic sealing part 15 of the tension member 12 will block the installation blind hole 9 , through the external pressurized glue injection device connected ...

Abstract

The invention discloses a basement outer wall crack waterproof treatment device and a crack blocking method, and belongs to the field of building crack blocking construction. The waterproof treatment device comprises a fixing mechanism installed on a wall structure and a pressurization plugging mechanism installed on the fixing mechanism and covering the periphery of a crack, waterproof and weather-proof glue is pressed into the crack through the pressurization plugging mechanism, and the crack of the inner side wall of the wall structure is coated with a plugging agent in advance. A pressurized injection type is adopted for plugging the crack for waterproof treatment, a pressurized protective cover covers the outer side of the crack, waterproof and weather-proof glue is injected in a pressurized mode through a flexible isolation piece, then the outer side is pressurized, the waterproof and weather-proof glue on the inner side of the flexible isolation piece is pressed into the inner side of the crack, the complete plugging effect is achieved, and DuLouWang in the cracks and at the inner side cracks can be connected into a whole, so that the durability of the plugging materials is better facilitated.

Description

technical field [0001] The invention relates to the technical field of construction crack plugging construction, in particular to a waterproof treatment device for cracks in outdoor basement walls and a crack plugging method. Background technique [0002] The side wall of the basement is prone to cracks due to temperature or uneven settlement, and the cracks are prone to water seepage. This problem has always been a common problem in the quality of construction projects, which brings great troubles to people's lives. For the waterproof treatment of basement side wall cracks, grouting and waterproof coating are generally adopted, but the effect achieved is not ideal. The main reasons are: 1) The method of grouting cannot achieve long-term plugging effect, because the concrete slab As time changes under the action of internal stress and external force, the cracks of the concrete slab will also change, and the original grouting will lose its effect after the cracks change. 2)...
