Introduction: Flexible waterproof casing is generally applicable to buildings with vibration or tight waterproof requirements where the pipeline crosses the wall; rigid waterproof sleeve is generally applicable to buildings requiring general waterproof at the place where the pipeline crosses the wall; if the wall where the flexible waterproof sleeve passes through the wall, in case of non coagulation

flexibility Waterproof casing It is generally applicable to buildings with vibration or strict waterproof requirements where the pipeline crosses the wall; Rigid waterproof casing Where general building waterproofing is required; Flexible waterproof casing If the wall passing through the wall is not concrete, it should be changed into concrete wall, and the casing pipe should be solidified in the wall at one time; the waterproof sleeve is applied to construction, chemical, steel, tap water, sewage treatment and other enterprises. Flexible waterproof casing is generally applicable to buildings with vibration or strict waterproof requirements where the pipeline crosses the wall. After the casing part is processed, the surface of the casing pipe shall be painted with one coat of top coat (including camphor Dan or cold primer oil). Waterproof casing is divided into rigid waterproof casing and flexible waterproof casing. The flexible waterproof casing is mainly used in places with high requirements such as civil air defense wall and pool, while the rigid waterproof casing is generally used in the basement where the pipeline should pass through. Shanghai Luoying pipeline equipment Co., Ltd. reminds you to indicate the diameter of flexible water-proof casing pipe when ordering. Products over DN 1400 and wall thickness more than or less than 300 mm can be customized. Next, the paper analyzes the requirements of flexible waterproof casing used in basement
1. In the design of basement waterproof engineering scheme, the flexible waterproof casing should follow the basic principle of prevention first and drainage auxiliary, and suit measures to local conditions, with advanced design, reliable waterproof and reasonable economy. The design can be carried out according to the requirements of basement waterproof engineering fortification table.
2. According to the actual situation, flexible waterproof casing or rigid waterproof casing can be selected for basement flexible waterproof casing, and rigid flexible combined waterproof scheme can be selected when necessary. Under special requirements, multiple fortification schemes, such as empty frame and sandwich wall, can be selected.
3. The underground engineering is relatively complex, so the underground soil, water body and groundwater level should be mastered in the design, and the effective fortification should be adopted in the design to ensure the waterproof quality.
4. When the underground outdoor waterproof working face is used, the external anti sticking method can be used, and the external anti sticking method can be used to construct the flexible waterproof casing.
5. When the basement water level is higher than the basement ground, the overall concrete structure should be considered in the basement design to ensure the waterproof effect.
6. Soft protective layer, such as polystyrene board, can be used for the protection of underground outdoor waterproof layer.
7. The determination of the basement fortification elevation is based on the water level elevation provided by the survey materials, plus 500mm as the fortification elevation. The upper end can be waterproof, and the underground water is designed according to the waterproof basement.
8. For general basement waterproof engineering design, the key anti pressure or self waterproof function of the wall shall be applied, and then the external waterproofing of coiled material (i.e. treatment of upstream water surface) shall be conducted. The waterproofing method of coiled material shall be constructed in accordance with relevant requirements.
