Description
Technical field
The invention belongs to sponge city technical field, more particularly to it is a kind of integrate accelerate the recessed of diafiltration and water storage
Formula greenery patches structure and method.
Background technology
In recent years, as the fast development of human industry, Urban Environmental Problem are increasingly serious, it is well known that urban green space
Refer to transplant trees flowers and plants and arrangement auxiliary facility, substantially covered by green plants, and be assigned to certain function and
The place of purposes.Urban afforestation can improve Urban Natural ecological quality, be advantageous to environmental protection；Improve City Life Quality,
Debugging enironment psychology；Increase the aesthetic effect of City landscape；Increase urban economy benefit；Be advantageous to city guard against disaster；Purify air
Pollution.Among the greenery patches of numerous forms, concave herbaceous field is one of them important part, and concave herbaceous field is a kind of
Elevation is less than the public lawn on surrounding road surface, also referred to as Low elevation greenbelt.With " flower bed " on the contrary, its theory is accepted using open space
With storage rainwater, have the function that to reduce outside runoff and arrange, in general Low elevation greenbelt there are certain requirements to recessed depth, Er Qieqi
How unmodified soil property is.It is mainly that " face " can accept more rainwater compared with " wire " of Glassed swale, and in it
Portion plant is more based on the draft of native country.
At present, water storage is one of main function of traditional concave herbaceous field；The water storage function of traditional concave herbaceous field is main
Determined by two aspects：First, the size of lower concave space, two, the water-holding capacity of greenery patches in itself；Obviously, it is preceding once lower concave space determines
What the reservoir storage of person was to determine；And the water-holding capacity of the latter is then mainly determined by the infiltration rate made skin graft, the infiltration rate of skin-grafting
Bigger, then within the unit interval, more rainwater can be imported underground and be stored by greenery patches；Due to existing concave herbaceous field
The speed ratio that seeps water is relatively low, therefore when heavy rain arrives, rainwater can not quickly be infiltrated underground deep layer, and then cause substantial amounts of rainwater
It is wasted into city planting ductwork.Therefore, design and develop a kind of by accelerating greenery patches infiltration speed and then raising rainwater utilization
Technology seem it is particularly important.
The content of the invention

300~400mm of filling height.
Non-woven geotextile bed course 5：It is arranged between artificial back fill course and sandy gravel stratum, prevents that upper layer of soil, impurity etc. are stifled
Collector pipe 7 is filled in, while certain catharsis also is played to the rainwater of infiltration.
Sandy gravel stratum 6：Purification is played a part of to the rainwater permeated, prevents from blocking collector pipe 7, it is artificial to maintain upper strata
The water and soil structure of back fill course 4.The water storage space of concave herbaceous field is added simultaneously.Gravel particle diameter is more than osmosis type collector pipe 7
Opening diameter.
Osmosis type collector pipe 7：It is arranged between sandy gravel stratum, collects the water that mozzle 3 flows down.Catchment on tube wall uniformly
Permeability hole is laid, the aperture of perforate and perforate density determine according to the permeance property of upper strata back fill course.Portion can so be met
Divide water to be seeped under continuing by collector pipe in lower soil, part water is flowed into cistern 11 again, play water conservancy diversion, infiltration is one
The function of body.Two layers of collector pipe is set, and every layer of osmosis type collector pipe is in netted laying, adds water storage, water seepage function.In order to anti-
Only osmosis type collector pipe 7 blocks, in the outer wrapping non-woven geotextile of osmosis type collector pipe 7.
Native soil 8：The original soil of unmodified processing.
Overflow pipe 9 is set along position on concave herbaceous field 1, for collecting rainwater that concave herbaceous field overflows extremely
Municipal storm sewer.
Electromagnetic valve 10 is installed in the interface of osmosis type collector pipe 7 and cistern 11；Electromagnetic valve 10 is arranged at infiltration
On type collector pipe 7, for controlling the rainwater into cistern 11, electromagnetism is closed when water level reaches and sets water level in cistern 11
Valve, rain-water accumulating is set to be stored in concave herbaceous field.The rainwater that cistern can not be entered is discharged into from overflow pipe 9 to municipal rain
Waterpipe.
Cistern 11：The rainwater that osmosis type collector pipe 7 flows into is collected, when cistern 11 is full, unnecessary rainwater can be by overflowing
Head piece 12 is discharged in Urban Rainwater Pipe Networks.
Cistern overfall 12：The rainwater that overflows of cistern 11 is collected to municipal storm sewer.
Immersible pump 13：It is arranged in cistern 11, for extracting the rainwater in cistern 11, by spray irrigation pipe 14, filtering
Device 15 is back to greenery patches sprinkling irrigation through shower nozzle 19.
Spray irrigation pipe 14：Collect rainwater to the shower nozzle 19 that immersible pump 13 extracts and carry out greenery patches sprinkling irrigation.
Filter 15：The granule foreign extracted by immersible pump 13 in the rainwater to come up is intercepted, prevents rain impurities in water to spray
Fill the blocking of pipe 14 and shower nozzle 19.
Liquid level induction meter 16：It is arranged in cistern 11, is consistent with the height of overflow pipe 12, when water level reaches liquid level
The electromagnetic valve 10 on signal-off osmosis type collector pipe 7 is transmitted during induction meter, letter is transmitted when water level is less than liquid level induction meter
The electromagnetic valve 10 on osmosis type collector pipe 7 number is reopened again.
Switch board 17：Control electromagnetic valve 10 and liquid level induction meter 16.
Inspection shaft 18：Each pipeline such as spray irrigation pipe 14 and shower nozzle 19, osmosis type collector pipe 7 is observed and safeguarded.
Shower nozzle 19：Carry out Greenland Irrigation.
The course of work of above preferred embodiment is：
The system integrates the functions such as infiltration, water storage and reuse.Infiltration facility can either be played to rainfall infiltration and net
Change acts on, and rainwater-collecting can be got up be used again.
When rainfall intensity is smaller, greenery patches surface without water storage or water storage height not less than the height of mozzle 3, into up concave type
The rainwater in greenery patches all passes through artificial back fill course 4, non-woven geotextile bed course 5, the seepage flow of sandy gravel stratum 6.
When rainfall intensity exceed it is a certain amount of when, due to the speed by being oozed under artificial back fill course 4 be far smaller than rainfall speed
Degree, along with the rainwater on surrounding road surface can be flowed into concave herbaceous field by receiving water pipe 2, so can be stored above concave herbaceous field
More rainwater.When just beginning to rain, rainwater can pass through artificial back fill course 4, non-woven geotextile bed course 5, the seepage flow of sandy gravel stratum 6；
When the rainwater that greenery patches top layer is collected highly exceedes 3 upper port of mozzle, part rainwater, which begins through mozzle 3 and flowed directly into, to be oozed
In saturating type collector pipe 7, the water section in collector pipe 7 continues to ooze to periphery deeper soil, partly flows into cistern 11.When logical
When crossing liquid level induction meter and sensing that cistern 11 is full, electromagnetic valve 10 is closed by switch board 17 and prevented in osmosis type collector pipe 7
Rainwater go successively in cistern 11, rain-water accumulating is stored in concave herbaceous field.It can not be oozed by concave herbaceous field storage more
Remaining rainwater in overflow pipe 9 through being discharged into municipal storm sewer.Stormwater overflow is so both prevented, and can is received to rainwater
Collect and be used.
Rainwater in cistern 11, spray irrigation pipe 14 is drawn into by immersible pump 13, intercepted by filter 15 in rainwater
Granule foreign, through shower nozzle 19 for concave herbaceous field spray.
