Description
Technical field
A kind of inlet for stom water is the utility model is related to, more particularly to a kind of early-stage rainwater for slope collects the rainwater of processing
Mouthful.
Background technology
As Urban Water Environment environmental protection concept is constantly strengthened, point-source pollution is effectively controlled, urban runoff pollution
Problem increasingly highlights.Urban runoff pollution level is relevant with different type in city land surface condition, is shown according to related data, city
The runoff pollution degree of city's land for roads is the most serious, and SS, COD, heavy metal, polycyclic aromatic hydrocarbon etc. are included in Runoff contaminants.
Runoff pollution control measure in sponge urban construction theory be widely used in runoff pollution control it is newly-built and
In the road construction project built up, its measure includes Rain Garden, grass planting ditch, biology and is detained band etc..
At present, build up road use more sets low influence development facility (can dissolve initial stage in the greenbelt of both sides of the road
The rainwater of pollution) control road runoff pollution.It is now current how early-stage rainwater to be introduced into the low influence development facility set
Urgent problem to be solved.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides the rain that a kind of early-stage rainwater for slope collects processing
The mouth of a river, greening outer interior low influence exploitation in both sides of the road can be used for after filtration treatment effectively by Initial Runoff rainwater-collecting
Facility, reduce the runoff pollution of early-stage rainwater.
To achieve these goals, the technical solution of the utility model is as follows：A kind of early-stage rainwater for slope is collected
The inlet for stom water of processing, including set on the slope with slopes degree identical inlet for stom water body, the inlet for stom water body
It is provided with rain perforaled strainer in upper port, the space under the road surface of the inlet for stom water body is divided into intercepting drain and overflow ditch, described section
The depth for flowing ditch is less than the depth of overflow ditch, and intercepting drain is located at the high side on slope, is set between the intercepting drain and overflow ditch
Downflow weir, climb over downflow weir after rainwater in intercepting drain is full and overflow to overflow ditch, cut a dirty pipe one end and connected with the bottom of intercepting drain,
Drainpipe connects with the bottom of overflow ditch, and the described section of dirty pipe other end is connected with the water inlet on continuous filter top, the continuous filter
Among set the bottom of overflow well described in overflow well to be connected with one end of the percolating pipe of continuous filter bottom, the percolating pipe it is another
One end is connected with overflow ditch bottom, and gravel layer is provided with the bottom plate of the continuous filter, and the top of the gravel layer sets multilayer
Filter layer, the porous drainage tube that early-stage rainwater is drawn to continuous filter is provided with the gravel layer.
Using such scheme, rain initial stage, the rainwater that overflow flows down from slope initially enters intercepting drain, passes through intercepting sewer
Continuous filter is incorporated into, by the filtration treatment of the filter layer of continuous filter, is then drained into from drainage tube in the greenbelt of both sides of the road
Low influence development facility in utilized.When Rainfall runoff is big, flow velocity is big, rainwater on the one hand can be by inlet for stom water
Rain perforaled strainer is flowed directly into overflow ditch, and on the other hand can climb over downflow weir into the rainwater in intercepting drain enters overflow ditch, this
When rainwater greatly reduce relative to initial rainwater pollutant.Municipal rain pipe is directly discharged into by drainpipe after into overflow ditch
Net, it is used for municipal greening water etc. after next step is handled.Now same rain flows into continuous filter from intercepting sewer, works as diafiltration
When the rainwater water surface in pond is higher than the well head of overflow well, rainwater overflows to percolating pipe from overflow well, and overflow is returned to by percolating pipe
Ditch.
In such scheme：The multiple layers of filters is quartz sand layer and geotextile layer, and the quartz sand layer is located at gravel layer
Top, the geotextile layer are located at the top of quartz sand layer.Geotextile layer can intercept larger debris, and quartz sand layer can be further
The effect for playing filtering.
In such scheme：The overflow well is coaxially disposed with continuous filter, is easy to arrange.
In such scheme：The width of the intercepting drain is less than the width of overflow ditch.So the volume of intercepting drain will compare overflow
The volume of ditch is much smaller, and the amount that later stage rainwater enters intercepting sewer is less.
Beneficial effect：Inlet for stom water of the present utility model can be realized effectively that the Initial Runoff of rainy initial stage or the when of spotting is dirty
Dye rainwater is separated with later stage rainwater, and the low of both sides of the road is drained into after effectively simple processing is carried out to Initial Runoff contaminated rain water
Influence in development facility, reduce pollution of the initial polluted rain water to the rainwater in municipal Storm Sewer Network, reduce municipal rainwater treatment
Cost.
