Waterproof structure construction method

Abstract

The invention discloses a waterproof structure construction method, and relates to the field of waterproof structure construction. According to the scheme, after a layer of alkaline permeable base layer treating agent or acidic permeable treating agent is constructed on the surface of a base layer, an acidic self-adhesive waterproof roll is constructed on an alkaline permeable base layer treatingagent layer, or an alkaline self-adhesive waterproof roll is constructed on an acidic permeable base layer treating agent layer; or an acidic waterproof coating is firstly applied to the alkaline permeable base agent layer, and then the acidic or alkaline self-adhesive waterproof roll is applied, or the alkaline waterproof coating is firstly applied to the acidic permeable base agent layer, and then the acidic or alkaline self-adhesive waterproof roll is applied. Through the chemical reaction of acid-base neutralization between the base layer treating agent and the self-adhesive roll or between the base layer treating agent and the waterproof coating, the problem that the self-adhesive waterproof roll and the base layer are not firmly combined can be effectively solved, and the bonding performance and integrity of the waterproof roll and the base layer are enhanced.

Description

technical field [0001] The invention relates to the field of waterproof structure construction, in particular to a waterproof structure construction method. Background technique [0002] At present, the construction technology of polymer modified asphalt self-adhesive waterproofing membrane is widely used in the field of waterproofing by dry bonding method or hot laying method. During construction, the base (construction surface) is usually cleaned first, and the Clean the dust, construction waste and other impurities on the base, and then use a roller (similar to a tool for painting the wall) to apply the base treatment agent to the base, the purpose of which is to enhance the adhesion between the waterproof material and the base After the base treatment agent dries, strengthen the joints, such as yin and yang corners, and through-board pipes. The waterproof membrane is directly attached to the base surface coated with the base treatment agent or the self-adhesive membrane...

AI Technical Summary

Problems solved by technology

[0007] 1. Even if the base layer is cleaned, a small amount of dust will still remain. At this time, it is difficult for the base treatment agent to be bonded to the base layer reliably. At this time, if the self-adhesive coil or paint is pasted, it may be damaged later Empty drums appear and the paste is not firm enough to easily cause water leakage

[0008] 2. Since the base layer itself is not sticky, even if the self-adhesive waterproof membrane is pasted on the base layer through the base treatment agent, the adhesion is only achieved through the adhesive properties of the membrane itself, and the membrane and the base layer cannot be integrated. slightly less waterproof

[0009] 3. Due to the characteristics of concrete, some tiny cracks will appear in the later stage of the base layer. If this problem is not solved in advance when constructing the waterproof layer, the risk of leakage will increase

[0010] 4. Due to the need for vibration during concrete construction, during the vibration process, the aggregate sinks and the slurry floats up, so the strength of the surface of the base layer is slightly poor, and it is easy to powder and sand, and the adhesion effect between the waterproof membrane and the base layer is not ideal
