Many friends in the basement, pay attention, before we were not sure what this is the waterproofing of the underground wall , then let us Xiaobian now introduce you to the waterproofing practice of the underground wall, and everyone should understand What are the preparations for the waterproofing of the underground outdoor wall and what are the basic rules and precautions for this underground outdoor wall waterproofing practice. First, the underground outdoor wall waterproof preparation 1. Review the drawings before construction, clearly understand the structural and technical requirements in the construction drawing of the basement project, and prepare the construction plan and technical measures for the waterproofing of the basement. 2. The construction of the basement waterproofing project should be carried out according to each process. After each process is qualified, the next process can be carried out. 3. The waterproof material used in the construction must have a certificate of appearance, and the materials must meet the design requirements. 4. The construction must comply with the current national fire protection and environmental protection regulations. 5. The relevant construction technicians shall hold the professional construction personnel's employment certificate for the market construction committee. Second, the basic requirements for waterproof design of underground outdoor walls 1, the protection of the underground outdoor waterproof layer, you can take a soft protective layer, such as polystyrene board. 2, the basement waterproof engineering design plan, should abide by the basic principles of prevention and supplementation. 3. The underlying project is more complicated. The designer should understand the underground soil quality, water quality and groundwater level, and take effective defense to ensure the waterproof quality. 4. When the maximum water level in the basement is higher than the basement floor, in order to ensure the waterproof effect, the design should consider the overall reinforced concrete structure. Third, the underground outdoor wall waterproofing practices 1. The outdoor enclosure waterproofing project is divided into ç ¼ structural engineering and anti-seepage ç ¼ structure self-waterproof. The mixing ratio of the basement floor of the basement to 0.6Mpa waterproof structure shall be determined by the laboratory, and the impermeability level shall be one level higher than the design level (0.2Mpa). 2, the base plate waterproof layer is two, using a coil-paint combined with waterproof anti-case. The coil is made of 1.5mm thick EPDM waterproofing membrane, and the waterproof coating is made of 2mm thick polyurethane waterproof coating. 3. The underground outdoor enclosure structure is self-waterproof except for the anti-seepage structure of the underground outdoor wall. The same two waterproof layers are made of coil-paint combined with waterproofing scheme. The coil is made of 1.5mm thick EPDM waterproofing membrane. The waterproof coating uses 2mm thick polyurethane waterproof coating. The protective layer of the waterproof layer is made of 40 thick polystyrene board. After the side wall protection layer is excavated within 1 m, the 2:8 lime soil is layered and tamped backfill. The compaction factor is >0.95. 4. When the basement roof is not inside the upper building main body, the top plate should be waterproof. The waterproof layer is also made of coil-paint combined with waterproofing scheme. The waterproof layer protective layer is 50mm thick C20 fine stone enamel. Fourth, underground outdoor wall waterproofing precautions 1. When the basement waterproofing construction work, relevant operators should wear helmets. 2. The construction materials are flammable, and the materials storage and construction site must comply with the relevant national fire protection regulations. 3, the use of solvents such as xylene should be the corresponding anti-virus measures. 4. When working with waterproof construction personnel, do not wear waterproof layer on the shoes with nails, pay attention to the protection of finished products. What is the waterproofing practice of this underground outdoor wall? We have introduced above, there are some preliminary preparations before the waterproofing of the underground outdoor wall, and what are the basic requirements of the waterproofing practice of this underground outdoor wall. I hope that these underground outdoor wall waterproofing practices of Xiaobian are introduced. Can help you, everyone continues to pay attention to our decoration home network.
