Film.First impervious barrier and the second impervious barrier are all HDPE material, can be reliably connected with the casing of HDPE material.
Further, the protective layer is non-woven fabrics protective layer.Non-woven fabrics has water repellent, flexible, not combustion-supporting, nontoxic stingless
Swash property, it is cheap the features such as be widely used in the fields such as roof waterproof.
Further, there are gap between the end of groove inner sleeve and the first impervious barrier, the gap location is equipped with
HDPE filler.It will form certain gap between the end of casing and the first impervious barrier, this portion void filled with HDPE,
Ponding can be not only prevented, the intensity that casing is connect with the first impervious barrier can be also enhanced.
Further, the mode of the lap-joint of the first impervious barrier and casing hot air welding connects；Second impervious barrier and set
The mode of the intersection of pipe hot air welding connects.The first impervious barrier and casing, second can be prevented with the mode of hot air welding
An entirety, whole good water-proof effect are connected between infiltration layer and casing.
Further, filling with sealant between the end and casing of casing internal drainage pipe.It is sealed and is filled with sealant,
It can prevent rainwater from penetrating between drainpipe and casing.
Further, it is equipped with piece film in the lap-joint of casing and the first impervious barrier, one end of piece film extends along internal surface of sleeve pipe
To the end of drainpipe, the other end of piece film is connected with protective layer.Setting piece film is equivalent to increases one of waterproof layer, waterproof more
Better reliability.
Further, described is connected between film and casing with the mode of hot air welding；Piece film and the first antiseepage interlayer heat
The mode of wind welding connects.Hot air welding can link into an integrated entity piece film and casing, piece film and the first impervious barrier, the effect of waterproof
It is good.
