First, the toilet is leakproof.
1. When there is obvious water accumulation on the ground after the urinal is used, the water leakage at the water inlet of the squatting pit at the joint between the urinal and the drain pipe should be considered first. At this point, the ground at the water inlet of the urinal can be gently removed to check whether the rubber bowl is in good condition. If damaged, it must be replaced immediately. If it is bound with the original iron wire, it must be replaced with copper wire. 14, and the two wires are staggered and tied tightly, so that one end is firmly connected with the big head and the other end is firmly connected with the small head. The flushing riser must be connected to the toilet at a low angle.
2. Flooding effect of the floor drain with accumulated water is not good. When there is frequent water accumulation, the ground around the floor drain should be chiseled and the slope should be found again to make the floor drain. The edge of the floor drain should be carved into a splayed mouth. The floor drain should be sealed tightly with GK quick-setting plugging agent, and should be 30m below the ground. Then embed elastic cement waterproof coating and smooth it with HRM high-strength crack-resistant waterproof cement mortar.
3, wear floor riser should be embedded casing, and 20mm higher than the floor, casing external use GK rapid setting plugging agent sealing tightly, the gap between casing and riser sealed with elastic cement waterproof coating. When the floor needs to be chiseled, the chisel can be used to dig the hole, and it is forbidden to hit the hole with a sledgehammer. It is forbidden to block the hole with bricks, crushed concrete, wood blocks and aerated blocks. HRM high-strength crack-resistant waterproof pisolite concrete shall be used for filling, and the board surface shall be sunken to 10mm, and it shall be leveled twice with HRM high-strength crack-resistant waterproof mortar. The pipe root and internal angle should be smeared with small rounded corners or splayed grooves. Pick a hole and open a slope of 30 ~ 50 mm outside the hole edge.
4. The waterproof layer of toilet and toilet is the key to waterproof and anti-leakage. During the construction of waterproof layer, the leveling layer should be smooth and clean, and the roots of walls and pipes should be dense. For cast-in-place floor slab, chamfering should be done when tamping the floor slab, and the slope of the surface layer at the root of the wall should be as steep and smooth as possible.
Second, the cause of toilet leakage
1. Leakage at the joint between the toilet bowl and the drain pipe: because the height of the drain pipe is not enough, the depth of the toilet bowl outlet inserted into the drain pipe is not enough, and the joint is not tightly packed; The waterproof treatment of the bathroom is not good. After the toilet is used, there is water on the ground, the wall is wet, and even the roof wall below is wet and dripping.
2. Water leakage at the entrance of the well on the squat pit: during construction, the water inlet joint of the squat pit was smashed but not found, the rubber bowl on the squat pit was not firmly bound, or the iron wire rusted and broke after being bound with iron wire, and the joint between the rubber bowl and the water in the squat pit broke, resulting in water accumulation on the ground and wet walls after the squat pit was used. The lower roofs and walls are also wet and dripping with water.
3, sanitary ware installation is not firm, the reason is that the embedded wooden bricks are not allowed or not embedded during construction, sanitary ware installation is not firm, sanitary ware is loose and unstable when used, resulting in damage or leakage of pipe fittings.
4. Water seepage at the lower outlet of the floor drain: the elevation of the lower outlet does not adapt to the elevation of the ground or sanitary equipment, resulting in backward flow, poor drainage of sanitary equipment, water leakage at the weak part of the linoleum or rotting of the linoleum; The height of the water outlet on the floor sleeve is too small, so the water leaks directly from the sleeve to the lower roof.
5. Local or general leakage of the lower roof: due to the local aging and cracking of the unprotected linoleum after the linoleum is protected, and the hollowing and cracking of the leveling layer, the pipes passing through the floor are not jacketed, the holes are not handled properly after drilling, and there are impurities such as bricks and sawdust in the concrete, resulting in cracks at the junction between the blocked concrete and the ground, which leads to the weak bonding between the waterproof layer and the leveling layer and the formation of the water inlet. Water enters the structural layer through defects, making the roof leak.
6, waterproof height is not enough, so that wet spots or flow marks appear on the other side of the bathroom wall, and even flow to the next floor along the pipeline interface.
7, linoleum vertical rub mouth paste not firm, rub mouth become warped edge, or because of local deformation at the grass-roots level, resulting in linoleum flat facade junction rupture, resulting in the lower wall, pipeline holes around wet spots or weak flow marks.
