The complexity of the basement waterproofing is determined by the structure and use of the basement. How to waterproof, how to do waterproofing in the basement is a problem that everyone is very concerned about. The local lower room waterproof atlas is suitable for underground places where people stay for a long time or people often move. The underground continuous wall, the inner lining and the underground piled retaining wall directly become the basement of the outer model, including the subway, tunnel and pedestrian subway. Pay attention to the following points when doing protection: 1. General description of waterproof design of basement 2. Plane layout of hydrophobic layer in basement 3. Schematic diagram of drainage and drainage of basement 4. Combination of anti-discharge structure, foundation pit (or pile cap), section of drainage drainage pipe 5. Deep base pit of basement Pumping and drainage pre-buried well structure large sample 6. Basement waterproof design general description 7. Basement to pull template bolt (casing type, embedded type) node waterproof 8. Underground outdoor anti-adhesive waterproof structure diagram (I-level fortification) 9. Underground outdoor anti-outer coating waterproof structure diagram (П-level fortification) 10. Underground outdoor anti-outer waterproof structure (I-level fortification) 11. Underground outdoor defense External waterproof structure (I-level fortification) 12. Underground outdoor anti-outer coating waterproof structure. 14. Underground continuous wall waterproof structure diagram (П level fortification) 13. Underground outdoor anti-inner coating waterproof structure diagram (П level fortification) 15. Two-in-one underground continuous wall waterproof structure diagram (П-level fortification) 16. Basement overhead waterproof and waterproof Construction (Class I fortification) 17. Substrate floor and wall panel embedded with deformation joints. According to the national standard "Technical Specifications for Underground Engineering Waterproofing", "underground engineering must be designed waterproof, waterproof design should be accurate, reliable and economical." The basement of the project is not rated for waterproofing. In the case of high groundwater level and poor geographical environment, the underground waterproofing of the project should be designed with secondary waterproofing, that is, a structural self-waterproof and a flexible waterproof layer. However, this project only designs a structure that is self-waterproof, and does not have a flexible waterproof layer. It is inadequate for waterproofing and leaves a hidden danger. According to the on-site observation, there is no water in the contact between the north end corner of the basement and the ground. There are many cracks and water leakage on the ground. If there is a description of the basement floor or the reverse beam construction, it may be vibrated and not properly maintained, resulting in residual holes and cracks in the concrete; the backfill of the house is not enough to fill the soil and cause leakage. The above is the knowledge and related content of the basement waterproof atlas provided by Xiaobian.
