News Abstract: looking for the part of water seepage is a necessary condition for the next step of work; the water leakage in the inner wall of the reservoir is divided into inner side system vulnerability and two side system vulnerability,.
The leakage stoppage methods of professional pool are as follows:
1. Traditional leak stoppage construction method
The first step is to find the part of water seepage, which is a necessary condition for the next step of work. The water leakage on the inner wall of the reservoir is divided into inner side system vulnerability and two side system vulnerability. We should first identify the location of the inner side system vulnerability. In the next two sides system vulnerability search, it is very easy to find that they do not have the same horizontal line The mark of inner leakage point is 1.22 times larger than that of both sides.
In the specific project construction, we can choose Zhuoxing moisture-proof plugging and waterproof raw materials. We should first expand the gap of 4-6cm wide and 3-4cm deep. If the quality of concrete is not up to standard, the deep layer and total width can be expanded again. After cleaning, the tap water can be wet, and the expanded position will be covered with leakage to ensure tamping! Finally, carry out the ground leveling solution for the leakage location, and wipe the waterproof coating and moisture-proof coating here!
2. Grouting construction method
The key raw materials of leak filling grouting in the moisture-proof sales market are foam polyurethane rapid leak filling materials. When meeting water, such raw materials will rapidly produce chemical changes, resulting in a lot of foam plastics bonding concrete to each other, resulting in a water impermeable overall. Due to the introduction of a unique waterproof coating, the leakage location including the surrounding concrete will become a ground waterproof with elastic deformation working capacity, waterproof performance! When we carry out the actual project construction, we must open holes in the parts of water seepage or cracks, and the total number of openings should be solved according to the water seepage situation on the spot. In the grouting stage, the grouting from top to bottom is generally selected for the vertical leakage parts, and the horizontal cracks are grouted from one end to the other end or from both sides to the middle; when the working pressure of the grouting equipment is stable at 0.3-0.5cpa, the grouting can be terminated; if no leakage is detected, the grouting head shall be removed and the hole shall be smoothed with mixed mortar and other raw materials.
