Initial-stage flow-abandoning gutter inlet for sponge city construction
The invention discloses an initial-stage flow-abandoning gutter inlet for sponge city construction. An initial-stage rainwater outlet pipe is arranged at the lower part of a rainwater well, a self-floating rising type gutter inlet sealing device is arranged in the rainwater well, the self-floating rising type gutter inlet sealing device is made of a light high-durability material with the densitysmaller than that of water, and a flat grate gutter inlet is blocked when the self-floating rising type gutter inlet sealing device floats upwards to the flat grate gutter inlet; and a vertical grategutter inlet is formed in the side part above the rainwater well, a concave green land or a biological retention facility is arranged on the outer side of the vertical grate gutter inlet, after rainwater enters the rainwater well, the self-floating rising type gutter inlet sealing device floats upwards until the flat grate gutter inlet is blocked, and the rainwater stops entering the rainwater well and enters the concave green land or the biological retention facility through the vertical grate gutter inlet. The device can effectively solve the problems that when rainwater on roads for spongecity construction needs to be discharged into source emission reduction facilities such as the concave green land or the biological retention facility, the initial-stage rainwater pollution degree ishigh, plant death is easily caused, and maintenance in the green land is difficult.
本发明公开了一种用于海绵城市建设的初期弃流雨水口，雨水井下部设初期雨水出水管，雨水井内设有自浮上升式雨水口密封装置，所述自浮上升式雨水口密封装置由密度小于水的轻质高耐久性材料制作，上浮至平箅雨水口时封堵平箅雨水口；雨水井上方侧部设立箅雨水口，立箅雨水口外侧为下凹式绿地或生物滞留设施，雨水进入雨水井后，自浮上升式雨水口密封装置上浮直至封堵平箅雨水口后，雨水停止进入雨水井，通过立箅雨水口进入下凹式绿地或生物滞留设施。本装置可以有效解决海绵城市建设道路雨水需排入下凹式绿地或生物滞留设施等源头减排设施时，初期雨水污染程度高，易导致植物死亡、绿地内维护难等问题。
