Water inlet 1 place is provided with vertical reinforcement as trash rack 10, and this trash rack 10 blocks dirt as the first accepting rainwater. Designing a downward slope between water inlet 1 and ground D, the existence on this slope facilitates rainwater to flow rapidly in water inlet 1 from ground. The rainwater on ground or road surface causes water inlet 1 through organized domatic, gutter, and water inlet 1 is the interface that surface runoff enters water-accumulating body, and its position, quantity and dimension of opening should calculate according to catchment area, aquifer reservoir storage, design standard etc. be determined. General catchment area 8��30m2Should arranging a water inlet, the situation in conditions permit should arrange more, in order to collects rainwater nearby.
Arranging a U-shaped baffle plate 2 between water inlet 1 and the planting soil of greening pool, this U-shaped baffle plate 2 arranges a cover plate, this cover plate is used for preventing external impurities from falling in inlet well 3. U-shaped baffle plate 2 is highly for the thickness of plantation layer 4. U-shaped baffle plate 2 and cover plate are that conventional rebar is concrete prefabricated.
Arranging an inlet well 3 in the groove of U-shaped baffle plate 2, inlet well 3 is filled to aquifer 5 by coarse material (such as cobblestone, rubble etc.). The end face (namely in coarse material) of this inlet well 3 arranges a garbage barrier net 30, and rainwater is carried out second and blocks dirt by garbage barrier net 30. The end face of inlet well 3 is lower than water inlet 1 place plane 50��100mm, and the effect of this inlet well 3 is that rainwater causes aquifer 5 as early as possible, and before rainwater enters water-accumulating body, the foreign material such as the silt in current is precipitated, it is prevented that foreign material enter aquifer 5.
Water-accumulating body is made up of urban afforestation ground and the underground space, from being spatially divided into three layers: plantation layer 4, aquifer 5, basal layer 6. The greenery patches shape utilized is not limit, it is possible to be variously-shaped. Water-accumulating body abatement waterlogging mainly by the porous material quick adsorption in aquifer 5 and storage rainwater characteristic, utilize greenery patches that this device is set and have a large capacity and a wide range, can reach to receive rainwater on the spot, avoid concentrate runoff purpose; Utilize aquifer 5 to store a large amount of rainwater simultaneously, gradually rainwater is added to subsoil water, it is achieved the comprehensive utilization of rainwater.
Plantation layer 4 is green land topmost a layer, is generally all above the ground level or road surface (being commonly referred to sunk type when lower than road surface or ground). Plantation layer 4 thickness of earth covering first has to meet the minimum thickness of plant growing, and its thickness is also relevant with the kind of plant and the kind of earthing, and general thickness of earth covering is preferably greater than 30cm. Enough scopes should be reserved, it is ensured that the required soil body for arbor. Plantation layer is aquifer 54 times, arranges one layer of geotextiles 7 between two-layer. The effect of plantation layer 4 is the bedding providing growth for plant, meanwhile, also can absorb and store a small amount of rainwater time rainy.
The top side of aquifer 5 is connected with the bottom of inlet well 3, and the bottom side of aquifer 5 is provided with a discharge outlet. Aquifer 5 is positioned at plantation layer 4 times, by the porous material filling of strong permeability, high absorption property, as: building brick slag, cinder etc., its size is determined by required reservoir storage. The bottom surface of general aquifer 5 should be higher than level of ground water, between the original soil layer that aquifer 5 four sides is adjacent with periphery, all should arrange one layer of geotextiles 7. Aquifer 5 end face should smooth after re-lay geotextiles 7, the effect of geotextiles 7 is soil particle limit adjacent soil layer with water inflow aquifer 5. The effect of aquifer 5 is the water-holding capacity and the adsorption fouling thing ability that increase water-accumulating body, but also to take into account economic and practical principle simultaneously. Therefore, the porous material such as the Rhizoma Begoniae Willsonii in building waste, flyash all can become the object of selection. These porous material water absorbing capacities are strong, it is possible to implicit substantial amounts of rainwater at short notice, reach the effect that peak clipping reduces discharging. Porous material has the function of the pollutant such as adsorption of nitrogen, phosphorus, it is to avoid ground rainwater is directly discharged into underground, polluted underground water. Porous material wide material sources and cheap, reasonably utilize, it is possible to reach energy-saving and emission-reduction, turn waste into wealth. Aquifer packing material should remove the foreign material without absorbability such as grass roots, plastic bag, wooden unit wood flour.
Basal layer 6 can adopt original soil layer, should arrange one layer of geotextiles 7 between basal layer 6 and aquifer 5, and geotextiles 7 completely spreads the coarse sand that thickness is not less than 100mm above. When basal layer is for backfill soil, cohesive soil should be adopted to backfill, and compaction in layers.
