It is a kind of to strengthen the sponge urban ecology square rainwater utilization structure of retaining
Technical field
The present invention relates to environmentally friendly urban construction technical field, and in particular to a kind of sponge urban ecology square rainwater of enhancing retaining Utilize structure.
Background technology
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 completed region of the city more than 20% reaches target call, and the area to the year two thousand thirty more than 80% reaches target call.By This can be seen that country improve resident living environment and Urban Water Environment in the urgent need to sponge city requirement city is being rained When with oozing, it is stagnant, store, function net, with, row.The square proportion mated formation in whole city of mating formation is about 30%, there is rainwater The problem of road surface causes runoff pollution, water resource waste is washed away, therefore, the work of square and square in sponge city is given full play to With extremely important.
At present, sponge urban construction starts to widely popularize application at home, and the sponge on wherein square transform sponge city as A core point in construction.The sponge transformation on existing square is generally that its structure sheaf is changed into aquifer, and surface layer uses permeable pavement, Only reached oozed in sponge engineering, it is stagnant, store three point requirements, for it is net, be related to seldom with, row.This does not have for sponge theory Realized completely, for rainwater resource be used without give full play to.
The content of the invention
The present invention provides a kind of sponge urban ecology square rainwater utilization structure of enhancing retaining, and it collects and stores rain Water, then the rainwater saved is introduced into ecology isolation pier, it is that the green plants soil in ecological hard shoulder carries out moisturizing.
To achieve the above object, the sponge urban ecology square rainwater utilization knot of a kind of enhancing retaining involved in 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, the plain soil layer of compacting, the Roadbed Soil of the car lane are 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, and the ecology isolation pier is arranged on pervious concrete layer, it is described it is ecological every , bottom outdoor from pier top portion is connected with graded broken stone layer, and planting soil and suction for plant growth are provided with the ecology isolation pier Water bar, the water storage box is arranged on the plain soil layer of compacting, and described water suction bar one end is arranged in planting soil, and the other end is arranged on retaining In case.
Further, between graded broken stone layer and the plain soil layer of compacting, between road concrete layer and the plain soil layer of compacting Provided with waterproof geotextiles.
Further, the water suction bar in the ecology isolation pier is in funnel-form spiral shape.
Further, the water storage box is also associated with feed pipe.
Further, U-shaped ecological ditch, the U-shaped ecology are provided between the road concrete layer and pervious concrete layer Provided with the permeable grid for wrapping up permeable geotextiles at the top of ditch.
Further, the permeable grid, which is provided with to plant on planting soil, the planting soil, plant.
Further, the water level electric control gear for controlling feed pipe to supply water is additionally provided with the water storage box.
As preference, the ecology isolation pier is provided with multiple, and the multiple ecology isolation pier is arranged in order.
As preference, the ecology isolation pier is flower tubular construction.
As preference, water-absorbing sponge is provided with the water suction bar.
The advantage of the invention is that:It realizes that the collection to rainwater is stored by the water storage box of the plain soil layer of compacting.By burying The water suction bar of connection water storage box and planting soil, the rainwater saved is introduced by capillarity principle and given birth in graded broken stone layer It is that the green plants in ecological hard shoulder carry out moisturizing in planting soil in state hard shoulder.It also replaces sleeping using ecological U-shaped ditch Stone ditch, after the aquifer saturation of square, rainwater can be flowed into by slope aspect in ecological U-shaped ditch, to greening and the utilizing status of rainwater Further lifting.This structure construction is convenient, energy-conserving and environment-protective, lifting rainwater utilization and urban green coverage rate, it is cheap, safeguard letter The multiple advantages such as single.
