Does anyone know the methods and professional tools of waterproof and plugging, the matters needing attention and the detailed use methods of later maintenance and water leakage prevention?

A, waterproof plugging method and matters needing attention:

(1) For the buried tap water pipe joint, if it is found that it falls off or runs water, it is necessary to first remove the covering soil at the pipe joint, hollow out the pipe up and down, and expose the pipe joint with the length of1~1.5m. Clean all the attachments on the inner wall of the joint and dry the water marks. The socket and ferrule of the pipe joint are reset and straightened. First, plug them tightly in the upper and lower joints of the tap water pipe with flax.

(2) The method of repairing the exposed tap water pipe joint is to chisel the leaking joint into a vertical bell mouth, clean up the surrounding sundries, and then operate according to the plugging procedure.

(3) The water-tightness ratio (weight ratio) of ash and water is generally 7: 3, that is, 7kg of water does not leak powder. Add 3kg of water and stir it into a uniform slurry before use. When stirring, there is no water leakage, the water consumption should be strictly controlled, and the slurry should not be too dry or too thin, just right. one

(4) The conventional operation method of plugging with impermeable materials is relatively simple, as long as the water in the mixing spoon does not leak slurry, and it is quickly pressurized in the direction of slurry leakage and does not loosen. Thick pipes can be sealed like rubber or plastic film for several minutes. When the temperature is below zero in winter, you can also bake the joints with an open flame for 3-5 minutes to accelerate the solidification of cement slurry. When blocking water, the mortar mixed with ordinary cement with strength grade of 42.5 is cured for 3 days, and the effect is better.

(5) Used for plugging and repairing pools (pits), cabins, etc. Water can be put directly into the pool without leakage, pressed by a flat object with a certain weight, and then released after a few minutes of condensation and hardening.

(6) For cracks with serious water leakage, drainage method can be used, that is, plugging the joints first, then plugging the joints, and finally plugging the drainage holes.

(7) For large-scale water leakage, first find out the water leakage point, plug it with water, then add about 0.5% retarder with waterproof powder, and wipe the coral quickly with this slurry, and the effect is also quite good.

Second, waterproof plugging does not need special professional tools, but only common tools such as waterproof plugging materials and common construction flat shovel.

Third, the use of water leakage:

1. First cut the leaking point or joint into a vertical bell mouth, clean up the sundries or loose powder and moisten it with water.

2. Put one kilogram of quick-acting plugging agent into a pot or other stirring container, add 0.3~0.35 kilograms of water, and stir quickly to make slurry. When it is lower than 5oC, it should be stirred with water above 20oC.

3. Put the prepared plugging cement on your hand. When the cement feels slightly hot and hard, you can quickly press it in the direction of water leakage for a certain period of time before releasing it. Generally 10 minutes can block the water.

4. After water plugging, plaster with waterproof mortar for 7 days.

5. For the seepage pit, you can directly put the dry powder of quick plugging agent into the into the pit, then step on it with your feet, and then loosen your feet after hardening.

6. For joints with serious water leakage, the drainage method is used to plug the joints first, then the joints are blocked, and finally the drainage holes are blocked.

7. For large-area leakage, find out the leakage point, first block it with quick-acting plugging agent, and then plaster it with waterproof mortar.
