Technical field
The utility model relates to sponge urban construction field more particularly to it is a kind of suitable for newly-built community based on sponge city
The rain water collecting system in city.
Background technique
The urban modernization construction in China is getting faster at present, earth-shaking variation all is occurring daily, city is increasingly
Flourishing, high building stands in great numbers, but the development mode of traditional grey facade lighting and the inexpensive short-term benefit of pursuit is inevitably brought
Some problems, such as: Urban Flood Waterlogging, water resource pollution, urban heat land effect, level of ground water decline etc..
Based on this, the theory in " sponge city " is suggested, and how with " green " measure to be solved the problems, such as rainwater, is made to live
Environment, city can have good " elasticity " in terms of adapting to environmental change and reply as sponge, from
And allow migratory movement of the water in city more naturally, make ecological, livable, low carbon city, so that harmony between man and nature is coexisted, is
Owner provides more comfortable living space, is those skilled in the art's problem to be solved.
Utility model content
In view of the deficiency of the prior art, the utility model provide it is a kind of for newly-built community based on sponge city
The rain water collecting system in city；The rain water collecting system uses distributed collection mode, and occupied area is smaller, to cell rainwater
The buried depth and status requirement of pipe network are smaller, can save high-quality tap water, and city water resource shortage is effectively relieved.
A kind of rain water collecting system based on sponge city is provided to achieve the above object, and the utility model uses following
Technical solution:
A kind of rain water collecting system based on sponge city, including infiltrative recessed greenery patches, the recessed greenery patches downside
It is successively arranged backfill artificial soil horizon, backfill coarse sands layer, the first geotextile layer rainwater-collecting module, the second geotextile layer；The rain
The antiseepage film for wrapping up rainwater-collecting module is equipped between water collection module and the second geotextile layer；The rainwater-collecting module
Rainwater is emitted into clear water reserviors by a drainage pipeline.
Preferably, the rainwater-collecting module is arranged on the sectional descending board of ground library top plate.
Preferably, the drainage pipeline is equipped with the venthole extended through on recessed greenery patches ground.
Preferably, the clear water reserviors are located at the lower section of building concentration, and pressurization is arranged in the lower section of the building concentration simultaneously
Equipment sets one for pouring the intake for spilling and nearby afforesting near building concentration.
Preferably, the recessed greenery patches is in building body and part road periphery scattering device.
Preferably, overflow port is set in the recessed greenery patches, the overflow port is connected to cell Storm Sewer Network, is used for nothing
The rainwater of method storage and infiltration is emitted into cell Storm Sewer Network.
Preferably, the recessed depth in the recessed greenery patches is 100~200mm, can be done according to the actual conditions of surrounding enviroment
Adjustment, while adapting to different water storage demands.
In the prior art, conventional needle is exactly in the rainwater-collecting of the Storm Sewer Network end of cell one to the rainwater-collecting of cell
Pond, while being equipped with mechanically or electrically dynamic rainwater in collecting pit upstream and pre-processing assembling device, it is equipped with purification device in downstream, finally
It is to be connected to clear water reserviors and water supply device.The beneficial effect of the utility model compared with the prior art is:
1) the utility model is directed to the construction theory in newly-built community combination sponge city, using the soil is porous, gas permeability is steady
Fixed recessed greenery patches, while plus the plant of surface plantation, it can be good at purification and the relatively large initial stage rain of osmosis pollution
Water keeps the storage capacity of itself stronger, while its scope of application is wider, can fit in any greening position of cell
With larger or lesser area can be selected according to the actual situation.And the utility model ground library top plate do sectional descending board with
Place rainwater-collecting module, rainwater can be directly collected by a root canal road and be discharged into clear water reserviors, using permeability by force under
Recessed greenery patches enhances the utilization to rainwater, and rainwater is stored, permeated and is purified.
2) the utility model is collected since source, and the pollution of rainwater is relatively small, by recessed greenery patches pretreatment and
After purification, the water quality of rainwater can be guaranteed, and avoid secondary pollution.
3) traditional rainwater-collecting is limited to the absolute altitude of Storm Sewer Network, needs excavation very deep, and the utility model uses and divides
The rainwater-collecting for dissipating formula, can be set on ground library, be limited by place smaller, while solve Di Kuding to a certain extent
The problem of plate drains.
4) traditional rainwater-collecting is to need to be laid with a whole set of pipe network in entire cell, is recycled after rainwater-collecting is concentrated
Rainwater carries out afforesting to pour spilling；And the distributing rainwater-collecting of the utility model, it is equivalent in traditional mode rainwater utilization pipe network
In intake, do not need to be laid with a large amount of pipe network, save the laying of pipeline.
In conclusion compared to traditional mode in Storm Sewer Network end setting rainwater collection pool, it is this distributed
Rain water collecting system is in contrast: occupied area is smaller, smaller to the buried depth and status requirement of cell Storm Sewer Network, and every
Nearby intake is arranged in monomer, can cover neighbouring greening, therefore does not need to be laid with a large amount of rainwater reuse pipe network in cell.
After the distributing rain water collecting system is purified using the primary filtration of the water storage in recessed greenery patches and surface greening plus soil natural
Until clean rainwater, it is stored in rainwater-collecting module.And recessed greenery patches can be set near building body or road
Near, it is unrestricted so as to accept the rainwater of roofing and road simultaneously, it is applied widely.

Recessed greenery patches is arranged in shunting road periphery, shares 490m2, recessed depth 180mm being capable of useful storage 88.2m3.This example is also in cell
North and south is arranged two, and totally 100 cubic metres of rainwater storage tanks, the discharge pressure of the municipal Storm Sewer Network during can mitigating heavy rain subtract
Few water pollution；The setting of rainwater collection pool, that is, clear water reserviors and rainwater storage tank is the utilization of resources, prevention flood, urban landscape and ring
The functions such as border improvement combine together.
Reach 75% according to Hangzhou sponge urban construction standard requirements annual flow overall control rate, looks into that " sponge city is built
If technical manual " learn that corresponding dependable rainfall is 21mm, the synthesis rain of the cell is calculated by the economic and technical norms of cell
Measuring runoff coefficient is 0.560, then the rainwater total amount for needing to control are as follows:
V=10 × F × Ψ × H
Wherein V --- design is regulated and stored volume, m3
H --- dependable rainfall, mm；Value 21mm
φ --- comprehensive rainfall runoff coefficient；Value 0.560
F --- catchment area, hm2；Value 2.4111
V=283.5m3,
Practical rainwater storage volume is 288.2m3。
