What are the precautions for the construction of bentonite waterproof blanket?

　　Construction precautions for bentonite waterproof blanket:

　　1. Waterproof blankets should be protected from direct sunlight during transportation, and attention should be paid to waterproofing and moisture resistance. During storage, it should be elevated, and the waterproof blanket transported to the site should be used as early as possible on the same day.

　　2. During construction, construction workers should wear cloth shoes or soft soled shoes, avoid wearing hard soled shoes (such as spiked shoes and high heels), and walk or step on the waterproof blanket to avoid damage to the blanket.

　　3. When the next process or adjacent engineering construction is required to complete a certain progress of laying, the soil waterproof blanket that has already been constructed should be protected from human damage. Vehicles or other machinery should be reduced from rolling on the waterproof blanket.

　　4. During the construction of waterproof blankets, acceptance is required for the completed waterproof blankets. After passing the acceptance, clay should be promptly backfilled as a protective layer. When backfilling, attention should be paid to preventing damage to the bentonite waterproof blanket. The backfill soil should not contain crushed stones with a particle size greater than 10mm, and the thickness of the backfill soil should not be less than 30cm. The compaction degree of backfill should not be less than 85%.

　　5. When the construction cannot be completed on the same day, the unfinished waterproof blanket should be covered to prevent the weather and climate from affecting the waterproof blanket by hydration or strong sunlight exposure, reducing damage to the waterproof blanket.
