Kneel for the waterproof construction scheme of the reservoir?

1, grassroots should strive to level off, firm, clean, clean, can not have floating ash, stains, etc. , comply with the design requirements and acceptance specifications.

2. When the groundwater level is high, the bottom and outside of the pond wall should be made into blind ditch filter layers.

Second, the waterproof layer construction:

1. After the base treatment meets the requirements, scrape a layer of PA-A polymer cement slurry with a thickness of about 1- 1.5 mm on the leveling layer with a water cement ratio of 0.4: 1 (weight ratio).

2. Before the initial setting of the base, a layer of PA-C beneficial cement can be scraped as the waterproof layer with a thickness of about 2 ~ 3 mm and a water cement ratio of 0.25 ~ 0.3: 1 (weight ratio). The construction of the second waterproof layer can only be carried out after the final set of the first waterproof layer.

3. The scraping direction of the second waterproof layer should be perpendicular to the first one, and the plastering should be dense, with a thickness of about 2 ~ 3 mm and a water cement ratio of 0.25 ~ 0.3: 1 (weight ratio). It is more economical to stick the second waterproof layer directly.

4. The waterproof layer should be constructed at the bottom of the pool behind the wall, and the internal angle should be made into an arc. It is required that the bottom of the pool should be completely scraped along the pool wall at one time, leaving no seams and no leakage. If you need to leave a seam, you should leave it on the wall at a height of about 300~500mm, which is higher than the original concrete construction joint. The bottom waterproof layer and wall waterproof layer should be circled.

5. If the pool is on the ground, a layer of PA-C and PA-A beneficial cement should be scraped on the front and back as the waterproof layer.

6. Using polymer beneficial cement as waterproof tile of pool can refer to the practice of toilet.

7, waterproof layer and tile construction is completed, need to be maintained at room temperature for 5-7 days, no water can be stored during the maintenance period.
