Description

Hold integrative ecological ditch of straining of clean rainwater

Technical Field

The utility model relates to a sponge city field, in particular to hold integrative ecological ditch of straining of clean rainwater.

Background

Rainwater is a part of natural water circulation, can play a role in adjusting and supplementing regional water resources, and is often not effectively utilized due to factors such as concept, technology and the like in urban environment. Combines natural approach and artificial measure, and realizes rainwater infiltration, purification and storage to the maximum extent. Traditional escape canal can't collect and utilize the rainwater. The ecological filter ditch mainly collects road surface rainwater of roadways and sidewalks, but initial rainwater can generate a large amount of pollutants in surface runoff and cannot be directly recycled.

Disclosure of Invention

In order to solve the problems and disadvantages of the prior art, the utility model provides an integrated rainwater storage and purification ecological filtering ditch which can be applied to sponge cities, and can store and purify rainwater for secondary utilization; the construction is convenient and flexible; can be suitable for urban roads; is economical and beautiful.

The utility model discloses the technical scheme who realizes is:

the utility model provides an it strains ditch to hold integrative ecology of clean rainwater, includes filter layer, drainage blanket, concrete support plate, overflow pipe, cistern, its characterized in that: be equipped with the cistern under greenbelt or green planting, lay concrete support board, drainage blanket, filter layer directly over the cistern from the bottom up in proper order, the cistern is close to concrete support board department and installs the overflow pipe, and the overflow pipe is connected to the lake. The filtering layer can be used for planting plants and intercepting initial rainwater surface runoff pollutants, the drainage layer is used for conveying rainwater, the concrete supporting plate is used for filtering pollutants with larger particles, the water storage tank is used for precipitating pollutants such as floating small particles and weeds, and the precipitated rainwater flows into an artificial lake or a natural lake through the overflow pipe after reaching a certain storage height.

The utility model discloses still include geotechnological cloth, geotechnological cloth is laid between filter layer and drainage blanket.

The filtering layer is a sandy planting soil layer, and the thickness of the filtering layer is 80-200 mm.

The drainage layer is a natural gravel layer, the particle size of the gravel is 40-60mm, and the thickness of the gravel layer is 280-320 mm.

The concrete support plate is a concrete grid plate, the distance between grids is 20-30mm, and large-particle pollutants and gravels are prevented from entering the reservoir.

The reservoir is built by cement mortar, and is used for greening maintenance and road cleaning after rainwater is precipitated.

The overflow pipe is wrapped by non-woven fabrics, and the purified rainwater is discharged into a lake for secondary utilization.

The utility model discloses ecological operating principle who strains the ditch is: the filtering layer is sandy planting soil, so that initial rainwater surface runoff pollutants can be intercepted on the premise of ensuring the survival rate of plants; the natural gravel drainage layer of the drainage layer has the particle size of 40-60mm, and the large pores can ensure rainwater transmission; the concrete support plate is a concrete grating plate and is used for filtering pollutants with larger particles in rainwater; rainwater enters the reservoir, and pollutants such as small floating particles, weeds and the like are precipitated and then discharged into a lake through the overflow pipe.

The utility model discloses an ecological ditch of straining can collect and purify the rainwater, furthest's realization rainwater retrieval and utilization. The utility model provides an ecology is strained the ditch and can be drawn materials on the spot, preparation, simple to operate to because of its characteristic that can hold and purify the rainwater, can save a large amount of manual works, reduce construction cost. The utility model has the characteristics of reasonable in design, the construction is nimble, safe guaranteed, green.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings:

as shown in fig. 1, the utility model discloses constitute its characterized in that by filter layer 1, drainage blanket 2, concrete support plate 3, overflow pipe 5, cistern 4, geotechnological cloth 6: be equipped with cistern 4 under greenbelt or green planting, lay concrete support plate 3, drainage blanket 2, geotechnological cloth 6, filter layer 1 directly over cistern 4 from the bottom up in proper order, and 3 department's installation overflow pipes 5 of cistern 4 near concrete support plate, and overflow pipe 5 is connected to the lake. Filter layer 1 is the sandy planting soil layer, thickness is 150mm, both can plant the plant and can also cut off initial stage rainwater surface runoff pollutant, drainage blanket 2 thickness is 300mm natural gravel layer, the gravel particle diameter is 40-60mm, the great rainwater transmission that can guarantee of hole, concrete support plate 3 is the concrete grid board, grid interval 25mm, the great pollutant of filter particle, cistern 4 is built by laying bricks or stones by cement mortar, deposit and float the tiny particle, pollutant such as weeds, rainwater after the sediment reaches certain storage height and flows into the lake through

overflow pipe

5, 5 outsourcing one deck non-woven fabrics of overflow pipe, prevent that the overflow pipe from blockking up.

Use the utility model discloses the time, adopt the better material of water permeability to collect the rainwater under the prerequisite of guaranteeing the view, through grit, gravel, concrete support board etc. tentatively purify the rainwater, the rainwater deposits and secondary purification after getting into the cistern, set up the overflow pipe in cistern one side, treat that the rainwater deposits and arranges into the lake through the overflow pipe after accomplishing, the rainwater of arranging into the lake carries out the self-purification through the aquatic attitude system in the lake, rainwater after the self-purification can be maintained the afforestation, the road washes etc..
