Non-woven geotextile bed course 5:It is set between artificial back fill course and sandy gravel stratum, prevents upper layer of soil, impurity etc. stifled Collector pipe 7 is filled in, while also playing certain catharsis to the rainwater of infiltration.
Sandy gravel stratum 6:Play the role of purification to the rainwater permeated, prevents from blocking collector pipe 7, it is artificial to maintain upper layer The water and soil structure of back fill course 4.The water storage space of concave herbaceous field is increased simultaneously.Gravel grain size is more than osmosis type collector pipe 7 Opening diameter.
Osmosis type collector pipe 7:It is set between sandy gravel stratum, collects the water that diversion pipe 3 flows down.It catchments on tube wall uniformly Permeability hole is laid, the aperture of trepanning and trepanning density are determined according to the permeance property of upper layer back fill course.Portion can be met in this way It is seeped into lower soil under dividing water to continue by collector pipe, and part water is made to flow into cistern 11, 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, increases water storage, water seepage function.In order to anti- Only osmosis type collector pipe 7 blocks, in 7 outer wrapping non-woven geotextile of osmosis type collector pipe.
Native soil 8:The original soil of unmodified processing.
Overflow pipe 9 is set in the upper edge position of 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 set to infiltration On type collector pipe 7, for controlling the rainwater into cistern 11, electromagnetism is closed when water level reaches setting water level in cistern 11 Valve makes rain-water accumulating be stored in concave herbaceous field.The rainwater that cistern cannot 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, extra rainwater can be by overflowing Head piece 12 is discharged in Urban Rainwater Pipe Networks.
Cistern overflow port 12:The rainwater that overflows of cistern 11 is collected to municipal storm sewer.
Immersible pump 13:It is set 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 nozzle 19.
Spray irrigation pipe 14:It collects rainwater to the nozzle 19 that immersible pump 13 extracts and carries 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 nozzle 19.
Liquid level induction meter 16:It is set 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 when induction meter, and 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 nozzle 19, osmosis type collector pipe 7 is observed and safeguarded.
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.
When rainfall intensity is smaller, greenery patches surface is less than 3 height of diversion pipe without water storage or water storage height, into up concave type The rainwater in greenery patches all passes through artificial back fill course 4, non-woven geotextile bed course 5,6 seepage flow of sandy gravel stratum.
When rainfall intensity is more than a certain amount of, since the speed by being oozed under artificial back fill course 4 is far smaller than rainfall speed Degree, along with the rainwater on surrounding road surface can be flowed by receiving water pipe 2 in concave herbaceous field, 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 5,6 seepage flow of sandy gravel stratum; When the rainwater height that greenery patches surface layer is collected is more than 3 upper port of diversion pipe, part rainwater, which begins through diversion pipe 3 and flows 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 is prevented in osmosis type collector pipe 7 Rainwater go successively in cistern 11, so that rain-water accumulating is stored in concave herbaceous field.It cannot be oozed by concave herbaceous field storage more Remaining rainwater in overflow pipe 9 through being discharged into municipal storm sewer.Stormwater overflow is not only prevented in this way, but also rainwater can be received Collect and is used.
Rainwater in cistern 11 is drawn into spray irrigation pipe 14 by immersible pump 13, is intercepted in rainwater by filter 15 Granule foreign, through nozzle 19 for concave herbaceous field spray.
