Problems solved by technology

[0005] 1. Due to the deviation of the cast-in-place concrete during the installation process of the waterstop, the position of the waterstop is deviated or the force is large, it is easy to fall off or tear, the waterproof is invalid, and it is difficult to replace
[0006] 2. There will be structural gaps between the rubber waterstop and the concrete, and these gaps will seep and leak under long-term water pressure
[0007] 3. After the actual installation of the waterstop, the concrete under the waterstop is poured. Beca...

Embodiment 1

[0049] Such as Figure 2~3 As shown, the present invention discloses a method for waterproof sealing of deformation joints of pipe gallery, the steps of which include:

[0050] St1: construction preparation;

[0051] St2: Pre-treatment of bonding base;

[0052] St3: Apply chemical adhesive to the bonding base surface;

[0053] St4: Casting cavity construction;

[0054] St5: pouring of elastomer waterproof seals;

[0055] St6: Fixing and maintenance of elastomer waterproof seals;

[0056] St7: Clean up the scene.

[0057] In the steps of the method for waterproofing and sealing the deformation joints of the pipe gallery according to the present invention, in step St2, the pre-adhesive treatment of the bonding base is mainly to remove the pre-embedded foam board, bond the weak interface on the surface of the cast-in-place concrete, and remove holes and numbness. surface, etc., including the removal and grinding of the pre-embedded foam boards in the deformation joints, the...

Embodiment 2

[0071] As an embodiment of the present invention, such as Figure 4 As shown, in the step St2 bonding base treatment, after the concrete base surface treatment, add the step St21 beam joint inspection, by checking whether the concrete water content between the deformation joints of the pipe gallery is less than 25%, if so, go to step St3 Apply chemical adhesive to the bonding base surface; if not, dry the deformation joints of the pipe gallery, and then transfer to the step of St21 beam joint inspection until the concrete water between the deformation joints of the pipe gallery is less than 25%, enter step St3 to apply chemical adhesive on the bonding base surface.

[0072] This setting further ensures the reliability of the bonding surface between the elastic body waterproof seal 8 and the concrete 4 , and ensures the durability and shear resistance of the bond between the elastic body waterproof seal 8 and the concrete 4 .

Embodiment 3

[0074] As an embodiment of the present invention, such as Figure 5 As shown, compared with Example 2, before applying the chemical adhesive on the bonding base surface in step St3, the process of grinding the deformation joints of St23 is added to polish the deformation joints of the pipe gallery, and then enter the step St3 bonding base surface Apply chemical adhesive. This setting makes the surface of the treated concrete base should be flat, clean, and dry without hollowing, looseness, honeycomb pitting, scum, floating soil, release agent, oil and other dirt. This setting is more conducive to elastomer waterproof seals 8. Better adhesion between chemical adhesive and concrete.

Abstract

The invention discloses a waterproof sealing method for a pipe gallery deformation joint. High-elastic state waterproof sealing resin is cast in the deformation joint of an urban comprehensive pipe gallery in site, and thus waterproof sealing of the pipe gallery deformation joint is achieved. Concrete casting quality is not influenced by waterproof sealing, elastomer waterproof sealing pieces and concrete are subjected to seamless bonding, and possibilities of water seepage and water leakage do not exist; double-component polyurethane elastomer sealing materials are adopted, and the shearing action on stretching and contracting and large displacement at the end of the concrete can be met; meanwhile, the method furthermore has the beneficial effects of being relatively simple in construction process and rapid; and in addition, no waste liquid, waste gas and the like are generated in production of a high-elastic state waterproof sealing resin material, and the high-elastic state waterproof sealing resin material belongs to a green and environmentally friendly material and meets the requirement for construction of a smart and green city.

Description

technical field [0001] The invention relates to the technical field of pipe gallery construction, in particular to a waterproof sealing method applied to reserved deformation joints of urban underground comprehensive pipe gallery. Background technique [0002] Pipe corridors originated in Europe, the United States and other countries. At present, China is gradually carrying out pilot projects and vigorously promoting construction. It is the only way to build a modern smart city. As an arterial project of urban comprehensive facilities, it has long-term strategic significance for my country's urbanization construction. [0003] The application number is CN201420118478.X, which discloses a basement deformation joint waterproof device with a hydrophobic structure. A pre-embedded rubber waterstop extending into the basement floor is provided in the middle of each deformation joint, and a water stop is provided at the top of each deformation joint. The second rubber waterstop, by...
