Embodiment 2
Referring to Fig.1,2 and 4, a kind of construction method of urban road rainwater collecting and treating system includes the following steps:
Step1: four mounting grooves are first opened up in the two sides on the road surface of urban road 30, successively by sludge-tank 1, rainwater-collecting Pond 2, biological tank 3 and water storage tower 4 are put into mounting groove, and the discharge port 15 of rainwater collection pool 2 and sludge-tank 1 are passed through discharge nozzle 5 The discharge outlet 17 of rainwater collection pool 2 is connected to biological tank 3 by drainpipe 6 by connection, and the biological tank 3 and water storage tower 4 pass through Standpipe 7 is connected to;
Step2: being laid with cement solidification in mounting groove, and roadbed 28 is formed above cement.Roadbed 28 and urban road Between form gutter 29, the depth in gutter 29 is from both ends toward intermediate increase, and the entrance of rainwater collection pool 2 is placed exactly in row The centre in ditch 29,4 part of water storage tower are located at roadbed 28;
Step3: leakage board 31 is laid with above gutter 29.
The course of work: for urban road in design, the level height among road surface 30 is higher than the level height of two sides.Therefore When rainwater is fallen on the road surface 30 of urban road, rainwater can flow to the two sides on road surface 30 under self gravitation effect.Rainwater warp The gap for crossing leakage board 31 enters in gutter 29.And after rainwater flows into gutter 29, rainwater is past under self gravitation effect The intermediate convergence in gutter 29.Therefore, rainwater flows into rainwater collection pool 2 just past strainer 18.
With accumulation of the rainwater in rainwater collection pool 2, the water surface is gradually risen.When the water surface is flushed with discharge outlet 17, rain Water flows out discharge outlet 17 and enters biological tank 3 by drainpipe 6.Biological tank 3 to rainwater carry out biological treatment after by water tank Into water storage tower 4, water storage tower 4 puts aside rainwater.
And when needing the road surface 30 to urban road to sprinkle water, water pump 19 is started to work, and the rainwater of savings is conveyed It is located at the top of 28 top of roadbed to water storage tower 4.Since water pump 19 is supplied to the biggish power of rainwater, rain-impact driving Plate 26 impacts positioning plate 22 behind gap of the rainwater across adjacent two pieces of driving plates 26.Due to rainwater rushing to positioning plate 22 Power overcomes the gross weights such as positioning plate 22, driving plate 26 and limit plate 24, thus positioning plate 22, driving plate 26 and limit plate 24 etc. along The axial direction of locating shaft 21 is moved to positioning plate 22 towards the top of water storage tower 4 and abuts with the top of water storage tower 4.And when rain-impact drives When movable plate 26, since driving plate 26 is inclined to set, driving plate 26 is divided into along the circle of limit plate 24 impulse force of rainwater The component of circumferential direction and the component axial along locating shaft 21.Driving plate can be driven along the component of 24 circumferencial direction of limit plate 26 rotate around locating shaft 21, so that limit plate 24 be driven to rotate.When watering trough 25 is directed at connectivity slot 20, rainwater can pass through Watering trough 25 and connectivity slot 20 spray, and parabolically fall on road surface 30 under the effect of gravity.As limit plate 24 rotates, spray Sink 25 also rotates with it, so that rainwater emission direction also circumferentially rotates.Due to there are two the settings of watering trough 25, when One of watering trough 25 and connectivity slot 20 misplace, another watering trough 25 is aligned with connectivity slot 20 just, so as to guarantee Road pavement 30 is sprayed water always in 24 rotation process of limit plate.And when water pump 19 stops working, rainwater is no longer to positioning Plate 22, driving plate 26 and limit plate 24 etc. are impacted, therefore positioning plate 22, driving plate 26 and limit plate 24 etc. are in self gravity Lantern ring is moved to towards the top orientation far from water storage tower 4 along locating shaft 21 under effect to abut with limited block 27.At this point, limit plate 24 abut with the side of water storage tower 4, so that the rainwater in water storage tower 4 be avoided directly to be connected to ambient atmosphere, play to rainwater Protective effect.
And in the flow process of rainwater, rainwater can carry silt secretly, therefore silt also can enter rainwater-collecting with rainwater Pond 2.And silt is deposited under the effect of gravity on arc-shaped partition 12.And rainwater is then in the top of silt.When rainwater collection pool 2 In when being deposited with more silt, silt for arc-shaped partition 12 active force be greater than 12 self-deformation resistance of arc-shaped partition and Spring 8 for arc-shaped partition 12 active force when, arc-shaped partition 12 is cut from arc-shaped partition 12 towards the bottom of rainwater collection pool 2 Change to the bottom that arc-shaped partition 12 deviates from rainwater collection pool 2.The deformation band of arc-shaped partition 12 is moved, and deformation occurs for spring 8, thus band The both ends that moving armature 11 is moved to armature 11 are abutted with the first contact 9 and the second contact 10 respectively.At this point, circuit is in connected state State, motor 13 drive closed plate 16 mobile, and discharge port 15 is in the open state.Due to the silt mobility in rainwater collection pool 2 It is relatively strong, therefore flow out discharge port 15 and flow into sludge-tank 1 by discharge nozzle 5.
