Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not intended to limit the scope of the present invention.

, it is necessary to which explanation, unless otherwise indicated, " multiple " are meant that two or two in the description of the utility model More than a；The instruction such as term " on ", " under ", "left", "right", " interior ", " outer ", " front end ", " rear end ", " head ", " afterbody " Orientation or position relationship are based on orientation shown in the drawings or position relationship, are for only for ease of description the utility model and simplification Description, rather than the device or element of instruction or hint meaning must have specific orientation, with specific azimuth configuration and behaviour Make, therefore it is not intended that limitation to the utility model.In addition, term " first ", " second ", " the 3rd " etc. are only used for describing Purpose, and it is not intended that instruction or hint relative importance.

Be the biological arresting device structure diagram of the utility model one embodiment referring to Fig. 1, described device include from What top to bottm was set gradually regulate and store layer 1, packing layer 2, plantation layer 3 and aquifer 4, described device further include multiple be vertically arranged Absorbent material 12, the upper end of any absorbent material 12 is in the plantation layer 3, the lower end of any absorbent material 12 In the aquifer 4.

Specifically, a kind of biological arresting device that the utility model embodiment provides is broadly divided into four modules, on to Under be followed successively by layer 1 of regulating and storing, packing layer 2, plantation layer 3 and aquifer 4.Wherein, 1 height of layer of regulating and storing is 10-20cm, for collecting footpath Flow rainwater.So-called runoff rainwater, then be in Precipitation Process, due to that can not infilter the underlying surface into hardening down, and make in gravity With it is lower along earth's surface flow rainwater, wherein, underlying surface refers to the earth surface directly contacted with air lower floor.It is stagnant that rainwater flows through biology The hardening underlying surface for staying device adjacent converges to layer 1 of regulating and storing, and rainwater oozes under layer 1 of regulating and storing sequentially enters packing layer 2 and plantation layer 3 Filtered, the rainwater after filtering enters aquifer 4, realizes regulating and storing, purifying with collecting for rainwater.In addition, above device is also Multiple vertical absorbent materials 12 being interspersed in plantation layer 3 and aquifer 4 are provided with, when planting that water loss is serious in layer 3, The rainwater accumulated in aquifer 4 can be absorbed by absorbent material 12, moisture conveying is entered into plantation layer 3, for supplementing plantation layer 3 Moisture needed for middle plant growth, according to this come realize rainwater from reuse and plant from irrigating.It should be noted that water-absorption material 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 utility model embodiment is by setting multiple vertical absorbent materials being interspersed in plantation layer and aquifer when soil When moisture reduces in earth, absorb the rainwater accumulated in aquifer and be used for keeping the skin wet to soil in plantation layer, meet plant growth Water demand, realizes being irrigated from oneself of reuse and plant for rainwater so that the device that embodiment is mentioned in the present invention can obtain To adequately and reasonably applying, the frequency that manual maintenance device is effectively reduced from reuse of rainwater, extends the maintenance of device In the cycle, reduce maintenance cost.

Based on above-described embodiment, as a kind of optional embodiment, an overflow pipe being vertically arranged 5 is further included, it is described 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 that the utility model embodiment provides further includes an overflow being vertically arranged Pipe 5, the upper end of the overflow pipe 5 underlying surface at least low 5cm more adjacent than with device is at least higher 10cm than the top of packing layer 2, is located at Regulate and store in layer 1, the lower end of overflow pipe 5 is then in aquifer 4.When rainfall intensity is smaller, the rainwater collected in layer 1 of regulating and storing is highly Not up to the upper end tube nozzle height of overflow pipe 5 when, rainwater directly in layer 1 of regulating and storing under infilter into packing layer 2, plantation layer 3 reach Aquifer 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, portion Dividing rainwater to carry out shunting via the overflow pipe 5 to dredge, avoid since filter process is slower, rainwater is hoarded in layer 1 of regulating and storing gradually, Gradually adjacent with device underlying surface is equal for height of water level so that runoff rainwater can not continue to be temporarily stored in layer 1 of regulating and storing.Overflow pipe 5 Unnecessary rainwater can be excluded rapidly, and water level is maintained in a certain range so that layer 1 of regulating and storing can normally accumulate rainwater, Unnecessary rainwater reduces the water accumulating volume of earth's surface also from dredging on the ground into underground.

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 water outlet 9, the bottom water outlet 9 is located at the bottom of the overflow pipe 5, and the bottom water outlet 9 is higher than described The bottom of aquifer 4；The apertured partition 8 is located inside the overflow pipe 5, and overflow pipe 5 is divided into two parts, described with holes Partition plate 8 is higher than 3 bottom of the plantation layer；The horizontal branch pipe 6 protrudes the side wall for being arranged on the overflow pipe 5, the horizontal branch pipe 6 In the top of the apertured partition 8, the horizontal branch pipe 6 is positioned at the lower section at 3 top of plantation layer.

Specifically, overflow pipe 5 mainly includes horizontal branch pipe 6, apertured partition 8 and bottom water outlet 9, wherein bottom water outlet 9 Positioned at the bottom of overflow pipe 5, for the rainwater in overflow pipe 5 to be imported aquifer 4.It should be noted that bottom water outlet 9 compared with At least high 5cm in 4 bottom of aquifer, for avoiding water outlet 9 water outlet in bottom not smooth.Apertured partition 8 is above water storage with horizontal branch pipe 6 The top of layer 4, wherein, apertured partition 8 is located at the inside of overflow pipe 5, and overflow pipe 5 has been divided into two parts, and band up and down Bottom of the level height of hole partition plate 8 higher than plantation layer 3；Horizontal branch pipe 6 is located at the top of apertured partition 8, plants under the top of layer 3 Side, the horizontal horizontal protrusion of branch pipe 6 are arranged on the side wall of overflow pipe 5, its caliber is identical with the caliber of overflow pipe 5, and and urban rainwater Pipe network is connected, and when water flow is larger in overflow pipe 5, a large amount of rainwater can be transported to Urban Rainwater Pipe Networks purification and recycled.
