A kind of sponge urban ecology square rainwater utilization structure enhancing water storage
Technical field
The present invention relates to environmentally friendly urban construction technical fields, and in particular to a kind of sponge urban ecology square rainwater for enhancing water storage Utilize structure.
Background technique
Sponge city is a kind of urban construction new concept that country proposes.National house and town and country construction portion are required to 2020 Year, the area of 20% or more completed region of the city reaches target call, and the area to 80% or more the year two thousand thirty reaches target call.By This can be seen that country improve resident living environment and Urban Water Environment there is an urgent need to sponge city requirement city is being rained When have the function of seeping, be stagnant, store, is net, use, row.It is about 30% that square, which is mated formation in the specific gravity that entire city is mated formation, and there is rainwater The problem of road surface leads to runoff pollution, water resource waste is washed away, therefore, gives full play to the work of square and square in sponge city With extremely important.
Currently, sponge urban construction starts to widely popularize application at home, wherein the sponge on square transform sponge city as A core point in construction.The sponge transformation on existing square is mostly that its structure sheaf is changed to aquifer, and surface layer uses permeable pavement, Only reached in sponge engineering and seeped, is stagnant, storing three point requirements, for it is net, be related to seldom with, row.This for sponge theory not It is realized completely, being used without for rainwater resource is given full play to.
Summary of the invention
The present invention provides a kind of sponge urban ecology square rainwater utilization structure for enhancing water storage, collects and stores rain Water, then the rainwater saved is introduced into ecology isolation pier, moisturizing is carried out for the green plants soil in ecological hard shoulder.
To achieve the above object, a kind of sponge urban ecology square rainwater utilization knot enhancing water storage according to the present invention Structure is arranged between square and car lane, and the Roadbed Soil on the square is followed successively by permeable surface layer, permeable coagulation by pushing up the bottom of to Soil layer, graded broken stone layer tamp plain soil layer, and the Roadbed Soil of the car lane is followed successively by road bituminous layers, road by pushing up the bottom of to Road concrete layer and the plain soil layer of compacting,
It includes ecology isolation pier and water storage box, the ecology isolation pier setting in pervious concrete layer, the ecology every , bottom outdoor from pier top portion is connected to graded broken stone layer, and planting soil and suction for plant growth are equipped in the ecology isolation pier Plain soil layer is being tamped in water bar, the water storage box setting, and in planting soil, the other end is arranged in water storage the setting of described water suction one end In case.
Further, between the graded broken stone layer and the plain soil layer of compacting, between road concrete layer and the plain soil layer of compacting Equipped with waterproof geotextiles.
Further, the water suction item spiral shape funnel-shaped in the ecology isolation pier.
Further, the water storage box is also connected with feed pipe.
Further, U-shaped ecological ditch, the U-shaped ecology are equipped between the road concrete layer and pervious concrete layer The permeable grid for wrapping up permeable geotextiles is equipped at the top of ditch.
Further, the permeable grid is equipped with planting soil, and kind has plant on the planting soil.
Further, the water level electric control gear for controlling feed pipe water supply is additionally provided in the water storage box.
As preference, the ecology isolation pier be equipped with it is multiple, the multiple ecology isolation pier is arranged successively.
As preference, the ecology isolation pier is flower tubular construction.
As preference, water-absorbing sponge is equipped in the water suction item.
The present invention has the advantages that its water storage box by tamping plain soil layer, realization store the collection of rainwater.By burying The rainwater saved is introduced life by capillary phenomenon principle by the water suction item that water storage box and planting soil are connected in graded broken stone layer In planting soil in state hard shoulder, moisturizing is carried out for the green plants in ecological hard shoulder.It is also replaced using the U-shaped ditch of ecology sleeping Stone ditch, after square aquifer saturation, rainwater can be flowed into the U-shaped ditch of ecology by slope aspect, to the utilizing status of greening and rainwater Further promoted.This structure construction is convenient, energy conservation and environmental protection, promotes rainwater utilization and urban green coverage rate, cheap, maintenance letter The multiple advantages such as single.
