Be the biological arresting device structural representation of one embodiment of the invention referring to Fig. 1, described device include on to
Under set gradually layer 1 of regulating and storing, packing layer 2, plantation layer 3 and aquifer 4, described device also include multiple water suctions being vertically arranged
Material 12, in the plantation layer 3, the lower end of any absorbent material 12 is located at for the upper end of any absorbent material 12
In the aquifer 4.
Specifically, a kind of biological arresting device provided in an embodiment of the present invention is broadly divided into four modules, from top to bottom according to
Secondary is regulate and store layer 1, packing layer 2, plantation layer 3 and aquifer 4.Wherein, the height of layer 1 of regulating and storing is 10-20cm, for collecting runoff rain
Water.So-called runoff rainwater, then it is in Precipitation Process, due to the underlying surface into hardening can not be infiltered down, and under gravity
The rainwater flowed along earth's surface, wherein, underlying surface refers to the earth surface directly contacted with air lower floor.Rainwater flows through biology and is detained dress
Put adjacent hardening underlying surface and converge to layer 1 of regulating and storing, rainwater oozes to sequentially enter packing layer 2 and plant layer 3 under layer 1 of regulating and storing to be carried out
Filtering, the rainwater after filtering enter aquifer 4, realize regulating and storing, purifying with collecting for rainwater.In addition, said apparatus is also set up
There are multiple vertical absorbent materials 12 being interspersed in plantation layer 3 and aquifer 4, when planting that water loss is serious in layer 3, can lead to
Cross absorbent material 12 and absorb the rainwater accumulated in aquifer 4, moisture conveying is entered into plantation layer 3, planted for supplementing in plantation layer 3
Moisture needed for thing growth, according to this come realize rainwater from reuse and plant from irrigating.It should be noted that absorbent material 12
Should possess preferable water absorbing capacity and not perishable, for ensureing the water absorbing capacity and working life of absorbent material 12.
The embodiment of the present invention is by setting multiple vertical absorbent materials being interspersed in plantation layer and aquifer, when in soil
When moisture reduces, absorb the rainwater accumulated in aquifer and be used for keeping the skin wet to soil in plantation layer, meet plant growth moisture
Demand, realize being irrigated from oneself of reuse and plant for rainwater so that the device that embodiment is mentioned in the present invention can be filled
Divide reasonably application, the frequency that manual maintenance device is effectively reduced from reuse of rainwater, extend the maintenance period of device,
Reduce maintenance cost.
It is described as a kind of optional embodiment, in addition to an overflow pipe 5 being vertically arranged based on above-described embodiment
The upper end of overflow pipe 5 is regulated and stored in layer 1 positioned at described, and the lower end of the overflow pipe 5 is located in the aquifer 4.
Specifically, a kind of biological arresting device provided in an embodiment of the present invention also includes an overflow pipe 5 being vertically arranged,
The upper end of the overflow pipe 5 underlying surface at least low 5cm more adjacent than with device, it is at least higher 10cm than the top of packing layer 2, positioned at regulating and storing
In layer 1, the lower end of overflow pipe 5 is then in aquifer 4.When rainfall intensity is smaller, the rainwater height collected in layer 1 of regulating and storing does not reach
To overflow pipe 5 upper end tube nozzle height when, rainwater directly in layer 1 of regulating and storing under infilter into packing layer 2, plantation layer 3 reach water storage
Layer 4；And when rainfall intensity is larger, when the rainwater collected in layer 1 of regulating and storing did not had the upper end tube nozzle of overflow pipe 5 highly, part rain
Water carries out shunting via the overflow pipe 5 and dredged, and avoids because filter process is slower, and rainwater is hoarded in layer 1 of regulating and storing gradually, water level
Gradually adjacent with device underlying surface is equal for height so that runoff rainwater can not continue to be temporarily stored in layer 1 of regulating and storing.Overflow pipe 5 can be with
Unnecessary rainwater is excluded rapidly, and water level is maintained in certain limit so that layer 1 of regulating and storing can normally accumulate rainwater, unnecessary
Rainwater also from dredging on the ground into underground, reduce the water accumulating volume of earth's surface.
Based on above-described embodiment, as a kind of optional embodiment, the overflow pipe 5 includes horizontal branch pipe 6, apertured partition 8
With bottom delivery port 9, the bottom delivery port 9 is located at the bottom of the overflow pipe 5, and the bottom delivery port 9 is higher than described
