　　1. After passing the inspection of the landscape greening foundation, a 100mm thick plain concrete cushion layer is poured as the base layer for laying the bentonite waterproof blanket.

　　2. After the final setting of the cushion concrete, a waterproof blanket can be laid. When laying, the non-woven fabric side of the waterproof blanket surface layer should face the water surface downwards. The waterproof blanket and the cushion should be fixed with shooting nails (steel nails), with a length of 25mm. The steel nails should be evenly arranged along the longitudinal and transverse joints of the waterproof blanket, with a spacing of 300mm between the steel nails.

　　3. If there are piles, pipes, and other objects protruding from the bottom of the plate, the outlet of this area should be sealed with slurry like bentonite. The overlapping width of longitudinal and transverse joints should not be less than 150mm, and adjacent end joints should be staggered by more than 300mm.

　　4. The laying of waterproof blankets around the base plate should exceed the underground outdoor wall surface by no less than 300mm, and meet the minimum staggered spacing between adjacent end joints. Effective protective measures should be taken to prevent damage caused by stepping, immersion, etc., which may affect the overall waterproof effect. After the waterproof blanket is laid, a mortar protective layer should be laid in a timely manner.

　　5. Based on the actual situation of the artificial lake, it is recommended to lay bentonite waterproof blanket (GCL) from top to bottom. For slopes with small angles, they can be directly uncoiled and laid on the slope bank. And prepare a protective layer as soon as possible.

　　6. The bottom bentonite waterproof blanket (GCL) of the revetment should be overlapped and fixed with the bottom bentonite waterproof blanket (GCL) to form a complete waterproof system.

　　7. When laying bentonite waterproof blanket (GCL), one side of the woven fabric should face the wall and the other side of the non-woven fabric should face the water surface. Bentonite waterproof blanket (GCL) should be avoided as much as possible from overlapping on the facade and slope bank.
