Problems solved by technology

[0003]The JS waterproof coating used for a long time will be affected by the environment, and cracks will appear to affect its waterproof performance. JS waterproof coating has a self-repair function, but the repair effect of the waterproof layer is affected by Influenced by the characteristics of the material itself, the second is affected by the surrounding environment, the surrounding environment of the underground structure is complex, and the influence of the surrounding environment of the underground environment in different areas on the repair process of the waterproof coating is difficult to control. Only relying on the characteristics of the waterproof material itself, the repair ability of the waterproof layer is limited or even unsatisfactory. Engineering waterproof requirements

Embodiment 1

[0043] Embodiments of the present invention disclose a JS waterproof coating repair and enhancement structure, reference Figure 1-4 However, including the top plate waterproof structure, the bottom plate waterproof structure and wall waterproof structure, the top plate waterproof structure includes a JS waterproof layer 2, a waterproof protective layer 3, a repair maintenance layer 4, and a repair reinforcing layer 5, and the bottom plate waterproof structure comprises JS waterproof layers. 2, the waterproof protective layer 3, the repair maintenance layer 4, repair the reinforcing layer 5 and the pad layer 6, the wall waterproof structure includes JS waterproof layer 2, repair the maintenance layer 4, repair the reinforcing layer 5 and the waterproof isolation layer 7, the The reinforcing layer 5 is a calcium salt coating, and the repair maintenance layer 4 is a geotextile laying layer.

[0044] A JS waterproof coating repair and enhancement construction method, including the fol...

Embodiment 2

[0052] Added on the basis of Example 1:

[0053] Refer Figure 2-4 The top plate waterproof structure is disposed on the top floor of the underground building, and the structure from the concrete layer 1 is sequentially the JS waterproof layer 2, the reinforcing layer 5, the repair maintenance layer 4 and the waterproof protective layer 3, the bottom plate waterproof structure setting Under the underground building floor, the structure from the concrete layer 1 is sequentially the waterproof protective layer 3, the JS waterproof layer 2, the repair maintenance layer 4, the reinforcing layer 5, and the pad layer 6, the wall waterproof structure is disposed underground. In addition to the construction wall, the structure from the concrete layer 1 is sequentially the JS waterproof layer 2, the reinforcing layer 5, the repair layer 4, and the waterproof isolation layer 7 are repaired.

[0054] The underground buildings include underground warehouses, underground parking lots, undergrou...

Embodiment 3

[0062] The increase in Embodiment 1 or Example 2 is increased:

[0063] The temperature change difference between the construction ambient temperature is controlled within 5 ° C through the blower and sprinkler operation during the spray construction.

[0064] The premise of controlling temperature is to choose the most uniform moment of temperature in the day. When the temperature is too high, the water and the blast treatment are used or the spray ice is lowered. When the temperature is too low, the warm water is sprayed or passed through the heater. Treatment, maintain the humidity of the construction surface in a reasonable range during cooling and temperature rise treatment.

[0065] The repair reinforcing layer 5 is sprayed with a high pressure sprayer during spraying, wherein the ratio of calcium hydroxide and water in the calcium hydraulic calcium hydroxide coating is 1: 2, and when the wall is sprayed, the angle is sprayed, and the pre-buried line is encountered. Spray ar...

Abstract

The invention relates to the technical field of building waterproof construction, in particular to a JS waterproof coating repairing and reinforcing structure and a construction method. The JS waterproof coating repairing and reinforcing structure comprises a top plate waterproof structure, a bottom plate waterproof structure and a wall waterproof structure, the top plate waterproof structure comprises a JS waterproof layer, a waterproof protection layer, a repairing and maintaining layer and a repairing and reinforcing layer, and the bottom plate waterproof structure comprises a JS waterproof layer, a waterproof protection layer, a repairing and maintaining layer, a repairing and reinforcing layer and a cushion layer. The wall waterproof structure comprises a JS waterproof layer, a repairing and maintaining layer, a repairing and reinforcing layer and a waterproof isolating layer, the repairing and reinforcing layer is a calcium salt coating, and the repairing and maintaining layer is a geotechnical cloth laying layer. The calcium hydroxide coating is additionally arranged, so that the structure has sufficient calcium ions, the requirement for the surrounding environment is lowered, and when cracks occur, calcium salt promotes the waterproof layer to form solid colloid linkage and accumulation to block a water inlet channel, and the leaking stoppage purpose is achieved.

Description

Technical field [0001] The present invention relates to the technical field of building waterproof construction, in particular, to a JS waterproof coating repair and reinforcing structure and construction method. Background technique [0002] JS waterproof coating is an organic liquid composed of polymer emulsions such as polyacrylate emulsion, ethylene-vinyl acetate copolymer, and various additives, and inorganic fillers such as cement, quartz sand, light weight calcium carbonate and various additives. The composition of the inorganic powder is a two-component, water-proof building waterproof coating made of composite, composite. [0003] Long-term JS waterproof coatings are affected by the environment, crack affects its waterproof performance, and JS waterproof coatings have self-repair function, but the waterproof layer repair effect is affected by the material itself, the second is affected by the surrounding environment, the underground structure The environment is complicat...
