Underground pipeline leakage plugging treatment plan
Jan 08,2025
The settlement joints of underground projects are prone to water leakage. The treatment of water leakage in the settlement joints of underground projects has always been a major difficulty in maintenance. Usually, as long as there is a water leakage point in the settlement joint, it should be indicated that the embedded water stop belt has failed and the overall sealing treatment must be carried out. If only local treatment is carried out, water will flow into other parts and cause the failure of the plugging work.
Underwater special anti-corrosion and anti-seepage slurry is a new type of anti-corrosion and anti-seepage slurry. It is a special dry mixed slurry composed of dozens of inorganic components. It is gray in color, non-toxic and tasteless, flame retardant, environmentally friendly, and can be used in food and drinking water projects.
Solution for underground leakage plugging: First, chisel off the surface plaster layer, and the chiseled area should be 50-100mm wider than the crack area. Find the cracks or leaks on the cast-in-place slab. For those parts or gaps that are just seeping and the amount of leakage is not too serious, you can use the chisel to enlarge and deepen it, and then use a plugging agent (waterproof treasure, water-proof, plugging spirit, 801 plugging agent, plugging powder, etc.) to directly plug the leaking hole or gap, and squeeze or lightly hit it with a wooden stick or finger to squeeze it around to stop the water, and then apply a permanent sealing waterproofing agent on the surface to strengthen the waterproof effect. Those cracks are large, the leakage is serious, and the gaps are
