What method can be used to repair the water leakage in the pool?
1, surface repair method is mainly suitable for slender joints. Usually, film materials such as epoxy resin or resin-impregnated glass cloth are laid along the same crack surface. For the clean water tank, non-toxic and pollution-free environmental protection materials must be used, and suitable materials should be selected according to the cited requirements.
2. Filling method When the crack is wide, a V-shaped or U-shaped groove can be formed along the surface of the cracked concrete, which can be filled with resin mortar materials, and the surface can be reinforced by using materials such as impervious mortar or asphalt. Similarly, after treatment, it is necessary to wait for 7 days before the subsequent construction, so as to avoid the failure of the filling material.
3. Injection method When the crack width is small and deep, the repair method of injecting repair materials into concrete can be adopted. Firstly, an injection tube is arranged at the crack, and then it is closed by surface treatment.

Method of selecting suitable filling materials:
1. Waterproof cement mortar can be applied to the water surface for cracks with a large number of cracks and little competition between cracks, and the five-layer waterproof method with better effect is especially suitable for low water head. You can also use nitrile coating for waterproofing, that is, apply nitrile slurry on the leakage surface to form a waterproof covering layer. This is a treatment method with good effect and convenient construction.
2. For competitive and permeable cracks, sealing measures should be taken. The principle is to change large leakage into small leakage, change line leakage into point leakage, and change sheet leakage into empty leakage, so that the leakage is concentrated at one or several points and finally blocked.
The commonly used plugging material is coagulant mortar, that is, a proper amount of coagulant is added to cement slurry or cement mortar (at present, the commonly used coagulant is mainly water glass, which is prepared by adding a certain proportion of copper sulfate and potassium dichromate). For plugging without strength requirements, coagulant materials such as cyanine pulp and acrylic pulp can also be used.
