Specific embodiment
The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing It is not limited to as described below.
As shown in Figure 1 to Figure 3, under a kind of sponge city automatic irrigation Rain Garden, including from top to bottom set gradually Permeable formation 1, soil matrix layer 2, filter layer and drainage blanket 5.Reservoir 6, the pool wall of reservoir 6 are provided with below drainage blanket 5 Top is provided with drainpipe 9.
Permeable formation 1 is paved by active carbon, and several implantation holes are reserved on permeable formation 1.The permeable formation 1 can permeate rainwater, And having some strength, the soil matrix layer 2 being effectively ensured below is not lost by rain drop erosion.
Soil matrix layer 2 containing the sandy loam there are many nutriment by constituting, and kind is implanted with several plants 12, the plant thereon 12 kinds are planted in above-mentioned implantation hole.The plant 12 selects the plant for having landscape, vitality strong.Plant 12 selects in the present embodiment With sedum lineare, adaptability is extremely strong, does not select soil, can be grown in relatively thin matrix, have stronger Drought resistance and Tolerance to cold.As the growing tension in soil is disposed on roof for the Rain Garden under sponge city, energy Preferably utilize idle roof.And roof planting sedum lineare can play the role of it is good it is heat-insulated, cooling and it is energy-efficient, together When, the root system of sedum lineare is weak and thin, takes root shallow, form grass roots and matrix overall plate, not only can preventing rain wash fall matrix, and And the ability of roof waterproof layer is not penetrated, destruction will not be generated to roof structure.
Filter layer sets gradually quartz sand layer 3 and soil when implementing for being filtered to the rainwater of infiltration from top to bottom Work cloth 4 carries out two layers of filtering to rainwater, can reach better purifying water effect.Meanwhile geotextiles 4 can effectively obstruct soil Grain, avoids it from falling into drainage blanket 5, results in blockage, influence its drainage effect.
Drainage blanket 5 selects plastic draining board, and array is provided with several drainage holes on drainage blanket 5.It is selected when specific implementation poly- Styrene or polyethylene plastic cement drain bar, lighter in weight is firm in structure, while cost is relatively low.Array is multiple on drain bar Filtered rainwater can be quickly discharged into reservoir 6 below by drainage hole.
Each outer surface of reservoir 6 is coated with the waterproof roll that pitch is mixed with polyurethane, rainwater can be effectively prevent to leak.If More rainwater can be stored by setting reservoir 6, and the Rain Garden is made to have stronger water-holding capacity.Meanwhile being stored in reservoir Rainwater is handled by filtration, purification, can also be supplemented auxiliary domestic water and be used.The upper wall of reservoir 6 is provided with drainpipe 9, the rainwater in reservoir 6 more than setting water level can be expelled to outside the Rain Garden.When it is implemented, the drainpipe 9 is selected PPR pipe, the other end are connected to extraneous pond.
Further, which further includes fixing sheet frame 7.Above-mentioned permeable formation 1, soil matrix layer 2, filter layer, row Water layer 5 and reservoir 6 are all set in fixing sheet frame 7, and fixing sheet frame 7 is for supporting and fixing.Permeable formation 1, soil Be provided with waterproof layer between earth hypothallus 2, filter layer, drainage blanket 5 and reservoir 6 and the inner wall of fixing sheet frame 7, prevent rainwater from It is leaked in fixing sheet frame 7, influences the water storage effect of Rain Garden.
The Rain Garden is additionally provided with automatic irrigation device, automatic irrigation device be used in fine day automatically to plant 12 into Row is irrigated.When it is implemented, automatic irrigation device includes controller, aqueduct 8, humidity sensor 10, water pump 11, water supplying pipe 13 It is connected to one end of several spray heads 14, aqueduct 8 with reservoir 6, the other end is connected to the suction inlet of water pump 11, water pump 11 Delivery outlet is connected to water supplying pipe 13, and water supplying pipe 13 is connected to several spray heads 14, and several spray heads 14 are respectively arranged at several plants 12 top;Humidity sensor 10 is for detecting ambient humidity, humidity sensor 10 and controller Electricity Federation.It is especially dropped in fine day Signal is fed back to controller, controlled by water few season when the ambient humidity that humidity sensor 10 detects is lower than its setting value Under the control of device processed, water pump 11 starts automatically, extracts the water in reservoir 6 by aqueduct 8 and is pumped into water supplying pipe 13, each to spray First 14 respectively irrigate plant 12.By the irrigation time of setting, water pump 11 stops working, and irrigates and stops, while can set It sets controller not responding the signal of humidity sensor 10 in certain time later, avoids heavy irrigation.
Further, which is powered by battery 16.The Rain Garden is additionally provided with solar panels 17 and hollow support rails 15, solar panels 17 be set to the top plate of hollow support rails 15, can preferably absorb solar energy, and utilize Solar energy charges to battery.15 interior hollow region of hollow support rails is cable-through hole, and connection line is set to the cable-through hole It is interior.
The above is only the preferred embodiment of the utility model, it should be understood that the utility model is not limited to herein Disclosed form, should not be regarded as an exclusion of other examples, and can be used for other combinations, modifications, and environments, and Can be in contemplated scope described herein, modifications can be made through the above teachings or related fields of technology or knowledge.And this field The modifications and changes that personnel are carried out do not depart from the spirit and scope of the utility model, then all should be in right appended by the utility model It is required that protection scope in.
