Improved regulation and storage system for urban road rainwater collection and green land conservation

[0032] Such as figure 1 As shown, the improved urban road rainwater collection, regulation and storage system for conserving green spaces includes a control system, drain ditch 2, coarse filter tank 4, fine filter tank 5 and storage tank 8 that are sequentially connected, and coarse filter tank 4 and storage tank 8. The backwashing device 7 for flushing by the fine filter tank 5; the drainage ditch 2 is arranged on both sides of the road, and it can simply improve the drainage ditch 2 on both sides of the current road and just can realize the filtering effect.

[0033] To realize the filtering function, the drainage ditch 2 can improve its structure in the following ways. Specifically, the drainage ditch 2 includes a wall body 21 made of resin concrete and a plurality of equidistant installations on the top to collect rainwater from the road. The rainwater grate 23 in the drainage ditch 2 is hung with a frame-shaped filter grid 22 that filters the rainwater collected by the ra...

[0045] This embodiment is a further improvement made on the basis of embodiment 1 to the coarse filter pool 4 and the fine filter pool 5, specifically refer to figure 2 , the present embodiment is provided with silt collection boss 41 and silt collection groove at the bottom of coarse filter tank 4, and the bottom of fine filter tank 5 is provided with mud collection boss 51 and mud collection tank; Sewage pipe 43 is installed in the sediment Where the collection tank is located, the mud discharge pipe 52 conducts the mud collection tank and the silt collection tank.

[0046] The top surface of silt collection boss 41 and mud collection boss 51 is an inclined slope, and the direction of inclination of the two is all towards respective silt collection groove and mud collection groove, after setting like this, can realize to silt and The mud plays a certain role in diversion, so that the sediment is collected in the sediment collection tank, and the mud is collected in the mud ...

[0049] This embodiment is a further improvement on the arrangement of the sediment collection boss 41 and the mud collection boss 51 on the basis of Embodiment 2. The specific improvement method is the inclined surface of the sediment collection boss 41 (i.e. The top surface of the platform 41) faces the fine filter tank 5, and the inclined surface of the mud collection boss 51 (that is, the top surface of the mud collection boss 51) faces the coarse filter tank 4.

[0050] The unique arrangement of the top surface of the mud collection boss 51 and the silt collection boss 41 faces, its main purpose is to make the mud collection tank and the sediment collection tank close to each other, so that the cleaning coarse filter tank 4 and the fine filter tank 5 are gathered together Together, uniformly discharged into the soil. From figure 2 It can be seen that after this embodiment is set in this way, the mud collection tank and the sediment collection tank are only separated by a...
