Description
Technical field
The invention belongs to municipal engineering construction technical field, and in particular to a kind of roadway rainwater collection system and collection side
Method.
Background technology
Existing road draining generally collects rainwater on road surface by greenbelt both sides inlet for stom water, and rainwater on road surface passes through inlet for stom water stream
In entering rainwater inspection well, finally by Storm Sewer Network fed downstream water body.This drainage pattern has two kinds of drawbacks：One is in rainwater
When peak value, institute's rain is accessed into Storm Sewer Network, the load of Storm Sewer Network can be increased, cause downstream pipe network saturation even to fall
Fill；Two is that, by these are untreated, directly drain into downstream water with the early-stage rainwater for polluting to a certain degree, can so cause
The pollution of downstream water such as rivers and lakes etc., makes water quality degenerate or even eutrophication.
The content of the invention
It is an object of the invention to provide a kind of roadway rainwater collection system and collection method, the system and method can be to rain
Water carries out initial stage purification, the nervous situation of Storm Sewer Network discharge during reducing rainwater pollution, and alleviation heavy rain peak value.
What the present invention was realized in：
A kind of roadway rainwater collection system, including kerb, filter, ooze pipe, cistern, blow-down pipe, waste pipe；
The kerb is placed in greenbelt both sides, which is provided with some water inlets, and pavement of road rainwater is entered cistern by water inlet
In；
The filter is installed in the water inlet of kerb；
The pipe that oozes is embedded in greenbelt soil, is obliquely installed, for the water in greenbelt to be entered in cistern；
The cistern is used to collect rainwater, and carries out initial stage purification to rainwater；Including the first retaining room, the second retaining room,
Three retaining rooms, the first retaining room be used for collect from water inlet flow into rainwater and from ooze pipe inflow rainwater；First retaining room,
Second retaining room is separated by first baffle, and the first retaining room, the bottom of the second retaining room are connected；Second retaining room,
Three retaining rooms are separated by second baffle, and the second retaining room, the top of the 3rd retaining room are connected；In the second retaining room and
Three retaining rooms are provided with cover plate, and liquid level gauge is provided with the 3rd retaining room；
The blow-down pipe is connected with the 3rd retaining room, which is provided with valve, for the water of the 3rd retaining room to be vented；Work as liquid level gauge
When detecting in the 3rd retaining room water level and being less than certain liquid level, the valve closing；When liquid level gauge detects the 3rd retaining indoor water
When position is higher than certain liquid level, the valve opening, by the water discharge in the 3rd retaining room；
The waste pipe is connected with the first retaining room, for the water in the first retaining room to be entered in nearest sewage inspection well.
By such scheme, the blow-down pipe includes the first blow-down pipe and the second blow-down pipe, and the first blow-down pipe is according to certain slope
The nearest rainwater inspection well of degree slope aspect, the second blow-down pipe is connected with downstream water treatment facilities；First blow-down pipe is provided with motor-driven valve,
Second blow-down pipe is provided with manually or electrically valve.
By such scheme, the filter is trash rack.
By such scheme, immersible pump is provided with the 3rd retaining room, the immersible pump is connected with the second blow-down pipe.
By such scheme, the waste pipe is provided with manually or electrically valve, and normal condition is opened to close at the end of rainwater
Open.
By such scheme, the spacing between water inlet is 20 ~ 50 meters.
By such scheme, ooze pipe buried depth under greenbelt and be not less than 0.6 meter；Oozing, pipe surrounding fills gravel or other are porous
Material（Such as ceramic porous material, metal polyporous material etc.）, in the permeable geotextiles of filler outer wrap.It is described to ooze Guan Yushui
The angle of plane is 10-35 °.Oozing pipe can use perforated plastic pipe, sand-free concrete tube and gravel（It is broken）The combinations of materials such as stone are formed.
It is tube having holes to ooze pipe, and its porosity should meet infiltration and require.
In the present invention, the material of greenbelt both sides kerb, size and traditional road greenbelt kerb are not different.Water inlet
And trash rack arranges that its drainability must is fulfilled for road drainage requirement along greenbelt, i.e. its discharging capacity, it is necessary to more than pressing

Cistern collects the rainwater for oozing pipe and greenbelt both sides water inlets, will be polluted by itself special design structure
Rain water drainage is precipitated, and is stored；Blow-down pipe UNICOM cistern and rainwater inspection well or UNICOM's cistern and downstream water process
Device, can be vented to cistern：Waste pipe UNICOM cistern and sewage inspection well, by the waste water for precipitating by row
Useless pipe enters sewage network, and then is discharged downstream sewage treatment plant.
The present invention also provides a kind of method for carrying out rainwater-collecting using above-mentioned roadway rainwater collection system, including following step
Suddenly：
Rainwater on road is entered the first storage of cistern by the water inlet and the trash rack of water inlet on kerb
In hydroecium；The rainwater on greenbelt is entered in cistern in the first retaining room by oozing pipe；
During water in first retaining room flows into the second retaining room from the bottom of the first retaining room, the water overflow in the second retaining room enters
In 3rd retaining room；
When water level is higher than certain liquid level in liquid level gauge detects the 3rd retaining room, the motor-driven valve on the first blow-down pipe is opened, will
Water in 3rd retaining room is entered in rainwater inspection well；Certain liquid level is less than when liquid level gauge detects water level in the 3rd retaining room
When, the motor-driven valve on the first blow-down pipe is closed；When the water inlet liquid level of downstream water processing unit is higher than the 3rd retaining room liquid level, the
When water in three retaining rooms cannot realize gravity flow by gravity stream, by immersible pump by the water fed downstream water in the 3rd retaining room
Processing unit is processed；The sewage in the first retaining room is entered in sewage inspection well by waste pipe.
The beneficial effects of the present invention are：
First retaining room, the second retaining room are directly accepted greenbelt both sides water inlet and inlet screen, ooze the rainwater of pipe inflow,
Precipitation function by itself to rainwater, the rainwater after preliminary treatment enters the 3rd retaining room by overflow, realizes the net of rainwater
Change, reduce pollution of the rainwater to downstream water system；
The early-stage rainwater of a part can be retained, and the early-stage rainwater of preliminary purification is stored, both alleviate heavy rain peak
A part of early-stage rainwater can be carried out reject by value period subsurface stormwater pipe network again for the stressful situation that rainwater is discharged；
Rainwater is carried out into initial stage purification, the difficulty of subsequent treatment can have been reduced, be easy to the treatment of follow-up rainwater to utilize.
