Bentonite waterproof blanket construction precautions
1. The storage and transportation of bentonite composite waterproof blanket (GCL) should be waterproof, moisture-proof and strong against sunlight. When storing, the ground should be padded by overhead method, and the bentonite composite waterproof pad (GCL) shipped to the site should be used up on the same day. 2. When carrying out the next process or adjacent construction, the bentonite composite waterproof pad (GCL) of the completed process should be properly protected and there should be no human damage. 3, should try to avoid wearing nail shoes, high heels on the bentonite composite waterproof pad (GCL) stepping on; vehicles and other machinery should not crush bentonite composite waterproof pad (GCL). 4. In the construction of GM/GCL composite liner, the completed GCL should complete the construction of HDPE film or lay a 300mm thick clay protective layer on the same day. The construction of HDPE film or clay protective layer cannot be completed on the same day, and the GCL should be covered. In order to prevent rain and snow, GCL will be hydrated first and strong sunlight will be exposed to GCL. 5. For the anti-seepage and waterproof construction of GCL single-layer liners, after the completion of construction and acceptance, the soil, sand or stone with a specific gravity greater than 2.0 should be quickly backfilled. In order to prevent the damage of GCL during backfilling, the backfill should not contain gravel with a particle size larger than 10mm, and the thickness of the backfill should not be less than 30cm. The backfill should be backfilled and graded, and the compaction should not be lower than 85%.
