Description
Technical field
The utility model relates to urban rainwater reutilization technology fields, and in particular to a kind of rain for sponge urban construction
Water warfare structure.
Background technique
In recent years, meet rain must flood be increasingly becoming the chronic illness in many cities.Therefore, to not " seeing sea in city ", not
It is so simple only to carry out pipeline dilatation.All using fast row's mode, rainwater falls on hardened ground can only be from current many cities
Concentrate fast row in pipeline, heavy rainfall is once all not enough to feel to repair great pipeline, and this mode allows 70% in city
Rainwater lost in vain.
Sponge city refers to that city can be as sponge, in terms of adapting to environmental change and reply
By the water stored " release " when can absorb water, water storage, infiltration, water purification, and need with good " elasticity ", when for example, raining
Out and it is used.Therefore, sponge city realizes rain under the premise of ensuring municipal drainage prevention waterlogging safety to the maximum extent
Water to promote the recycling and ecological environmental protection of rainwater resource, and then is realized in the accumulation, infiltration and purification of urban area
The high standard and new demand that country proposes Urban Storm Flood management.
If most of rainwater is left rather than is drained, rainwater can be realized in the product of urban area to the maximum extent
It deposits, permeate and purifies, promote the utilization and ecological environmental protection of rainwater resource.That is, ' sponge city ' be expected to will be original
The water for largely draining into pipe duct end the links such as pass through absorptions in advance, save, permeate and digesting, and become and crack having for ' meeting rain flooded '
Effect approach, rather than by repairing big drainpipe.
Rainwater purification refers to rainwater is collected according to demand after, and by the rainwater of collection carry out purified treatment after
Reach the system met using standard.The rainwater of collection is roughly divided into two classes, roof rain water and rainwater on road surface, it is contemplated that at present I
State's atmosphere pollution situation is more serious, and the rain and impurity being collected into is more, and contamination sources are complicated.
Currently, it is too poor that the recycling water handled by rainwater purification still has water quality in sponge urban construction
The problem of, it can not only meet the use of city system well in this way, cause the rainwater comprehensive utilization rate collected low, because
This, also can not meet the theory and requirement of sponge urban construction and ecological environmental protection.
Utility model content
The utility model in order to solve the above problems existing in the present technology, provides a kind of for sponge urban construction
Rainwater purification structure, the rainwater structure realize rainwater in city under the premise of ensuring city prevention waterlogging safety to the maximum extent
Collection, infiltration, purification and utilization in range promote rain to not only can be effectively relieved and reduce the pressure of urban waterlogging
The utilization of water resource, moreover, very well satisfying the requirement of sponge urban construction.
The technical solution adopted in the utility model are as follows: a kind of rainwater purification structure for sponge urban construction, including press
Rainfall runoff direction is disposed with the preposition pool, Swampy Areas, discharge bay, the preposition pool and the water inlet for surface rain confluence
Mouth is connected, and accumulation has the rubble for filtering rainwater, the preposition pool and Swampy Areas setting between the water inlet and the preposition pool
There is water distribution gabion, the Swampy Areas include 2 malezales areas and 2 banados areas, it is provided with filter layer below the discharge bay,
Gravel is provided with below the filter layer, the periphery of the gravel is provided with permeable geotextiles, the permeable geotextiles lower section
It is provided with soil base, the delivery pipe being connected with urban rainwater canal system system, the discharge bay are provided in the water outlet
Inside it is provided with the inclination discharge tube and vertical overflow pipe of connection delivery pipe.
2 malezales areas are trapezium structure.
The banados area depth of water is 0-0.3m, and the malezales area depth of water is 0.3-0.5m.
Kind, which is implanted with, on the edge on the preposition pool resistance to rushes plant.
300~500mm of thickness of filter layer, the filter layer are coarse gravel.
The tube top mouth for stating vertical overflow pipe is concordant with the highest design water level of discharge bay, and the tube top mouth of overflow pipe is set
There is the grid for filtering.
The utility model has the beneficial effects that
It includes the preposition pool, Swampy Areas and the discharge bay being arranged by rainfall runoff direction that the utility model, which passes through, so that this reality
Sufficiently rainwater-collecting, purification, recycling and the theory of sponge urban construction can be combined with novel, thus ensuring city
Under the premise of safety of preventing waterlogging, collection, infiltration, purification and utilization of the rainwater in city scope are realized to the maximum extent, so not
It only can be effectively relieved and be reduced the pressure of urban waterlogging, promote the utilization of rainwater resource, but also very well satisfy sponge
The requirement of urban construction.
