Limit.
A kind of method that rainwater is controlled to be utilized that existing utility is transformed into of the present invention, as illustrated in fig. 1 and 2, should
Method is that existing for city greenbelt is transformed into the sunk type greenbelt 1 less than surrounding road or square, sunk type greenbelt 1
Transverse section use trapezoidal or arc-shaped structure, the plant that plantation rhizome is deeper in sunk type greenbelt；Sunk type greenbelt 1 end
Portion is embedded with rainwater soakaway trench 10；Along sunk type greenbelt 1 length direction, one overflow-type rainwater is set at interval of a segment distance
Mouth 2, overflow-type inlet for stom water 2 is higher than sunk type greenbelt 1 bottom surface；A cistern is built in each overflow-type inlet for stom water 2 side；
Being provided with permeable wall 6 in cistern and cistern is separated into two cavitys of A, B, wherein A cavity 4 is through rainwater collection collector 3 and overflow-type
Inlet for stom water 2 connects, and A cavity 4 is connected with relief sewer 8；B cavity 5 is connected with rainwater soakaway trench 10 through rainwater reuse pipe 9.Store
Pond is brick or the box pond of armored concrete, and the exterior wall in pond is waterproof body of wall, A the cavity 4 and B cavity 5 of cistern
Top is respectively equipped with cleanout 7, and cleanout 7 is provided with cover plate, and cover plate is concordant with districts and cities' road or square.
A kind of urban rainwater of the present invention according to said method composition controls to utilize system, and as illustrated in fig. 1 and 2, this is
System includes sunk type greenbelt 1, and sunk type greenbelt 1 is less than surrounding road or square, and the transverse section of sunk type greenbelt 1 is ladder
Shape or circular arc, plant in sunk type greenbelt 1 and be implanted with the plant that rhizome is deeper；Rainwater infiltration it is provided with bottom sunk type greenbelt 1
Pipe 10；Along sunk type greenbelt 1 length direction, one overflow-type inlet for stom water 2, overflow-type inlet for stom water 2 are set at interval of a segment distance
Higher than sunk type greenbelt 1 bottom surface；It is provided with cistern in each overflow-type inlet for stom water 2 side；A cavity 4 and B is included in cistern
Cavity 5, A cavity 4 is connected with overflow-type inlet for stom water 2 through rainwater collection collector 3, and A cavity 4 is connected with relief sewer 8；B cavity 5 warp
Rainwater reuse pipe 9 is connected with rainwater soakaway trench 10.Cistern is brick or the box pond of armored concrete, and the exterior wall in pond is not
Permeable body of wall, A cavity 4 and B cavity 5 top of cistern is respectively equipped with cleanout 7, and cleanout 7 is provided with cover plate, cover plate and ground
City's road or square are concordant.
Embodiment
As illustrated in fig. 1 and 2, this example sunk type greenbelt 1 uses less than surrounding road and square 150～200mm, transverse section
Trapezoidal or circular arc, preferably plants the plant that rhizome is deeper in sunk type greenbelt 1, with supplementing of more preferably absorbing that cistern bleeds back
Water.Sunk type greenbelt 1 arranges overflow-type inlet for stom water 2 at a certain distance, and spacing should be according to local rainfall by calculating really
Fixed, overflow-type inlet for stom water 2 is higher than bottom sunk type greenbelt 1 50～100mm, and overflow-type inlet for stom water 2 can use precast concrete
Or the material such as plastics, cast iron make, should water inlet position install 2cm between left and right away from grid (bar) miscellaneous to intercept larger volume
Thing, floating thing etc., prevent rainwater collection collector 3 blocked.Overflow-type inlet for stom water 2 connects rainwater collection collector 3, stormwater overflow drain pipe
8, reuse rainwater outlet pipe 9 typically can use the plastic pipe such as polyethylene, UPVC, it is possible to uses precast concrete pipeline, caliber
Being 100～200mm, drainage grade is not less than 0.01.Cistern can use armored concrete or waterproof brickwork construction to be outer wall
Leakage proof wall, volume determines through calculating according to local rainfall runoff control rate, and cell body is divided into two lattice by permeable wall 6, permeable
Wall 6 can use silica sand drainage brick, permeability concrete etc. to construct, and pond two lattice are respectively provided with cleanout 7, and cleanout 7 uses circle
Shape, diameter 700mm, cleanout 7 cover plate end face is equal with ground.Rainwater soakaway trench 10 uses PE or UPVC material, and seep water speed
Should not be too big, keep the water storage in cistern can continue within the time period of not rainfall slowly as far as possible and mend in greenbelt soil
Water, the time that arid area can bleed back according to practical situation proper extension.
The work process of the present invention and principle
During rainfall, rainwater enters sunk type greenbelt 1 after road surface, square etc. are collected, and in greenbelt 1, rainwater will be through soil
Under infilter into soil, rainwater is tentatively removed relatively bigger material at sunk type greenbelt 1 through plants such as flowers and plants and collects, and rainfall is further
Being enlarged to water level in greenbelt when being lifted to certain altitude, stormwater overflow enters overflow-type inlet for stom water 2, and overflow-type inlet for stom water 2 is
Floating thing, larger volume foreign material are intercepted by guard type water inlet, and overflow-type inlet for stom water 2 passes through rainwater by after rainwater-collecting
Collecting pipe 3 enters cistern storage, and cistern is divided into two lattice, lattice to be non-purified rainwater by permeable wall 6, and rainwater passes through permeable wall
6 enter an other lattice storage rainwater simultaneously will be cleaned, and after cistern storage is full, rainwater is expelled to Water in Rainwater Drainage by overflowing rain water pipe 8
In grid or gutter, after the permeable wall 6 of cistern purifies, side picks out reuse rainwater outlet pipe 9, rainwater outlet pipe 9
Pick out water permeating pipeline 10 by rain penetration after purification to greenbelt soil.
The present invention, mainly in combination with sunk type greenbelt and cistern, utilizes the purification that water-permeable brick or concrete have simultaneously
The effect purifying rainwater of rainwater is stored in cell body simultaneously, in conjunction with seepage well way will purify after rainwater bleed back in greening
Band, whole device define a rainwater infiltration, retain, collect, purify, reuse and the circulating system of discharge.This installation optimization
The purification technique that cistern is complicated, utilizes the mechanism of natural filtration, optimizes seepage well and directly bleed back the rainwater volume collected
Causing blocking well body or the drawbacks of pipeline such as mud foreign material, this invention simultaneously is particularly suited for arid area, can by rainwater slowly
Bleed back supplementary greenbelt subsoil water, alleviate arid area greenbelt plant because of the present situation of arid death, minimizing green land irrigation use
The water yield.
Needing emphasis that permeable body of wall is carried out process during the enforcement of this invention, permeable body of wall is recommended to use silica sand drainage water-permeable brick
Building by laying bricks or stones, the coagulation local product built by laying bricks or stones uses pervious concrete；The infiltration flow of soakaway trench need to carry out process, rainfall according to practical situation
Relatively multizone can strengthen infiltration flow, and arid area controls to bleed back flow and ensures that rain time does not stores persistently returning of rainwater as far as possible
Ooze.
