Description
Technical field
The utility model relates to a kind of urban rainwater discharging facility.
Background technology
City dilatation has now reduced the permeable area in the face of land, can not get effectively replenishing after making the underground water extraction, has not only reduced groundwater resources, and has caused the urban ground sinking, forms the underground funnel in city.Existing urban rainwater discharging facility has only discharge function, the main duct of discharging facility, arm and connection pipe, for the ease of discharging, be not less than 2/1000 with the gradient of horizontal plane, the manhole that is disposed has only very shallow clear mud pit, do not see through function, rainwater all directly is discharged among the rivers and lakes.In addition because all underground structures all adopt brick mix structure, to enter storm-water system very general so private connects sewage, thereby caused the severe contamination of water of river and lake, makes abundant rainwater resource loss, can not go down with adding to.Because amount of rainfall can not in time discharge when big, form the urban road floods easily in flood season in addition.
Summary of the invention
Only discharge impermeable deficiency in order to overcome existing urban rainwater discharging facility, the utility model provides a kind of have filtration and infiltration function, replenishes the urban rainwater discharging facility of underground water source.
The technical solution of the utility model is at the main duct of discharging facility, arm and connection pipe seepage well to be set, promptly part water inlet, manhole in the existing urban rainwater discharging facility, the well casing in the clear mud pit under the flow surface is deepened to 50 centimetres by 10 centimetres under the flow surface---and 300 centimetres, below well casing, open wide, under well casing, there are 50 centimetres---100 centimetres of dark holes, in the hole, fill up natural sand, ore deposit permeable filtering material that is cut, constitute seepage well.In the time of in rainwater deposits to seepage well, because the infiltration shaft bottom is to the high water of water of flow surface more than 50 centimetres, under the effect of hydraulic pressure, the hydraulic pressure that has strengthened at the bottom of the seepage well is strong, has quickened the infiltration to the stratum, and most of rain penetration is to underground.Simultaneously, can reduce main duct, arm and connection pipe, slow down the flow velocity of water, strengthen infiltration capacity the gradient of horizontal plane or parallel with horizontal plane.Though urban rainwater is not really clean, underground through entering behind the permeable material filtration and infiltration, again through the filtration, purification function of soil, enter underground water and can not constitute pollution underground water.
This urban rainwater discharging facility comprises main duct, arm, connection pipe and manhole, the head end of connection pipe is connecting water inlet, the end of connection pipe is connected logical with arm or main duct by manhole, the head end of arm is connecting manhole, the end of arm is connected logical with the main duct by manhole, it is characterized in that: main duct, arm, connection pipe are not have and ooze the concrete reinforced pipe in hole; Water inlet that has and manhole do not ooze the steel concrete wall in hole for having yet, seepage well tube of the no end is being set under these water inlets and the manhole, the degree of depth of the seepage well tube of water inlet is to be 50 centimetres to seepage well tube lower end at the bottom of the minimum water pipe from flow surface---200 centimetres, under the water castor of water inlet, collecting sewage reticular lamin is being set, the degree of depth of the seepage well tube of manhole is 150 centimetres from flow surface to seepage well tube lower end---300 centimetres, the cross-sectional area in the seepage well tube of manhole is 6 square metres---and 8 square metres.Under the seepage well tube, there are dark 50 centimetres---100 centimetres leaking well, fill up permeable natural sand, ore deposit quarrel filtering material in the leaking well.
For slowing down the flow velocity of rainwater in facility, the sloping gradient of main duct, arm, connection pipe is 0 to 2/1000.
In above-mentioned urban rainwater discharging facility, groundwater reservoir and first sedimentation basin and second sedimentation basin and filtering ponds supporting and that communicate are set, filtering ponds are arranged between second sedimentation basin and the groundwater reservoir, at the main pipe duct three driftings are set, first filtering ponds are connected logical with the main pipe duct by water inlet main duct and three driftings, groundwater reservoir connects logical through going out water conduit tube duct and another three drifting with the main pipe duct.First sedimentation basin precipitation filter quarrel, second sedimentation basin precipitate behind the clear mud by high water level enter that filtering ponds carry out disinfection, deodorizing, fine filtering, enter groundwater reservoir then.Through the rainwater after clean the processing, can directly supply the city and use, as providing water for fire-fighting, environmental sanitation, urban construction, gardens.
The utility model is provided with seepage well at main duct, arm and the connection pipe of discharging facility, and under the effect of hydraulic pressure, the hydraulic pressure that has strengthened at the bottom of the seepage well is strong, has quickened the infiltration to the stratum, and most of rain penetration is to underground.Simultaneously, can reduce main duct, arm and connection pipe, slow down the flow velocity of water, strengthen infiltration capacity the gradient of horizontal plane or parallel with horizontal plane.Underground through entering behind the permeable material filtration and infiltration, again through the filtration, purification function of soil, enter underground water and can not constitute pollution underground water.Most of rainwater is seeped into underground, not only makes underground water source obtain effective supply, and improves city fight-flood disaster reduction in flood season ability effectively.Groundwater reservoir is set, also can alleviates the water supply contradiction in city effectively being stored to groundwater reservoir behind the rainwater purification.
