Embodiment Construction
[0010] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0011] like figure 1 and figure 2 As shown, the present invention comprises a diversion cover 1 and a drain pipe 2 connected to the lower part of the diversion cover 1, the top opening of the drain pipe 2 is a drain outlet 3, and the drain pipe 2 is extended upwards by 5-10 cm, equal to the height of the roof. Or the water outlet hole 4 that can drain in an appropriate amount is offered on the drainpipe 2 pipe wall of slightly lower place.
[0012] Since the drainage pipe 2 is extended upwards by 5 to 10 cm, the drain outlet 3 is higher than the roof, and the drainage water level of the roof is increased, when a heavy rain strikes, the roof can store a certain amount of water, so the present invention can delay the time of roof rainwater outflow and reduce the The flood peak flow of urban surface rainwater reduces the harm of urban waterlogging. And becau...
