2, flexible waterproof casing filler material: asphalt hemp wire, polystyrene board, polyvinyl chloride foam board.

3, sealing paste: polysulfide sealing paste, polyurethane sealing paste.

4, when the flexible waterproofing casing is rolled into a type, the permissible deviation of perimeter: D2 ≤ 600, D2> 600 ± 0.0035D2.

5, through the wall at the concrete wall thickness should not be less than 300, otherwise the wall should be thickened on one side or both sides of the thickening, thickening part of the diameter of at least D5 + 200.

6, flexible waterproof casing casing weight to L = 300 calculation, such as wall thickness greater than 300, should be calculated separately.
