What are the methods of waterproof and plugging?

Waterproof and leak-filling, the traditional idea is to fill the leak. The latest waterproof and leak-proof method is to abandon this traditional concept. If the waterproof layer leaks, it is necessary to do a good job of waterproofing and leakage prevention outside the tiles. As long as the surface of the tile outside is waterproof, the waterproof effect is the same. Construction method of waterproof and leak-patching: use a knife to remove waterproof cement or glue between tiles, use a dryer to dry the ground for one day, and then fill the ditch with cement of the same color as the ground (the ground is filled with white cement and the ground is filled with black water mud, which is for indoor beauty. Then slowly inject a special CPC waterproofing agent into the cement. 1-2 days later, the waterproof agent and cement will be firmly adsorbed on the ceramic tile, effectively forming a stable waterproof layer. 1. Ultra-early strength self-leveling new cement-based grouting material is a kind of cement-based hydraulic grouting material with adjustable setting time, which has the characteristics of ultra-early strength, high strength, slight expansion, self-compaction, self-leveling, good groutability and simple construction. This product is a powdery material, which is convenient to use. According to the cement ratio of 0.35~0.45, directly add water and stir evenly to use. After pouring, there is no need to vibrate. This product is especially suitable for emergency repair projects, such as railway subgrade disease treatment project (without affecting train operation), grouting plugging project of Dabanshan Highway Tunnel in Qinghai at an altitude of 3,800 meters (in cold areas), Baihushan Tunnel in Yunnan, Tao Jing Tunnel outside Shanghai, etc. , has been successfully applied. In the rapid repair of No.4 blast furnace in WISCO, the ultra-early strength prepared from the developed ultra-early strength grouting material was adopted. 13. construction method: a. drilling: the principle of hole arrangement is to make it sparse first and then dense, then center the hole and punch it with a blower to thoroughly clean the ballast and silt in the hole. Through drilling, we can know the connectivity between holes, so as to determine grouting holes and exhaust holes; B. Grouting: Before grouting, water injection test shall be conducted to check whether the holes are unblocked, and then the ultra-early strength self-leveling cement-based grouting material shall be pulped with a blender according to the ash-water ratio of 1:0.4. After the prepared slurry is put into the slurry storage barrel, it is pumped to the working face by pressure for grouting. The grouting process can depend on the setting time of the slurry to ensure its stone strength.
