At the construction site of the bentonite waterproof blanket, the bentonite waterproof blanket for paving should be carried out on the same day. For construction that cannot be carried out on that day, the bentonite waterproof blanket should be covered to avoid rain or snow that may cause the bentonite waterproof blanket to be damaged. Solidification and sun exposure.

1. At the construction site of the bentonite waterproof blanket, the bentonite waterproof blanket for paving should be carried out on the same day. For construction that cannot be carried out on that day, the bentonite waterproof blanket should be covered to avoid rain or snow that may cause the bentonite waterproof blanket to be damaged. Solidification and sun exposure.

2. When backfilling soil, damage to the bentonite waterproof blanket should be avoided. Sand and gravel should not be included in the backfill, and the thickness of the backfill should be less than 30 cm. Backfilling shall be graded and classified backfill soil, and the density shall not be less than 85%.

3. Sodium bentonite particles have a strong water absorption capacity, so they are required to be kept dry during production, warehousing and transportation. In addition to requiring that the bentonite waterproof blanket be closely attached to the surface of the rural grassroots and not produce large wrinkles, it must also be Solve the rough conditions on the surface of rural grassroots.

4. When the sodium bentonite blanket is paved directly on the shotcrete base surface, there are often many tiny suspended positions between the blanket body and the surface of the rural base.

5. For the pile structure with relatively standard convex and concave fluctuations, the flatness of the surface is required to reach a turning radius of not less than 40cm. At this time, the joints between the bottom plate and the axillary corners must be carefully processed to ensure that the sodium bentonite at the bottom plate and side walls is The blanket can be smoothly connected.

How many years can fish pond anti-seepage membrane be used?

The fish pond membrane is particularly suitable for situations where the soil cannot retain water. In some areas, the sandy soil is filled with water and will leak out in a short time. In this case, the cost of using an anti-seepage membrane is lower than the traditional anti-seepage foundation. Construction is faster and subsequent maintenance is more convenient.
