In order to realize above-mentioned target, this utility model adopts the following technical scheme that:
The miniature reservoir of savings urban rainwater, including: for collecting the Each reservoir body of rainwater, the inhalant region being positioned at Each reservoir body top and the water reserve being arranged on Each reservoir body diapire, the water inlet of described inhalant region is equipped with cobblestone, described water reserve includes that the water storage module of an engraved structure, described water storage module are wrapped with permeable geotextiles；Urban rainwater can be saved by this miniature reservoir, a large amount of rainwater-collectings stored rather than is directly discharged into pipe network, reducing flood peak pressure, alleviate the discharge pressure of city planting ductwork, and water storage module is conducive to rainwater infiltration, recharge of groundwater and deposit water source.
Preferably, the vertical section of aforementioned Each reservoir body is shaped as the inverted trapezoidal that Di great Kou is little, and the shape of cross section of described Each reservoir body is strip or ellipse, specifically can arrange flexibly in conjunction with the practical situation of surrounding enviroment.
More preferably, aforementioned water inlet at least two, it is divided into the both sides of Each reservoir body.
It is highly preferred that the mean diameter of aforementioned cobblestone is 3-8cm, thickness is also to plant on 5-15cm, and cobblestone to be implanted with Rhizoma Acori Graminei, during plantation can on cobblestone a small amount of planting soil of spreading, the pollutant in rainwater are played the preliminary effect intercepted and purify.
It is further preferred that be additionally provided with the high fence of 50-100cm around aforementioned Each reservoir body, in Each reservoir body, at fence, kind is implanted with parasol grass, and parasol grass not only can be with purifying rainwater, additionally it is possible to play the effect beautifying surrounding enviroment.
Yet further, aforementioned water storage module is made up of PP material, and this material has stronger acid-alkali-corrosive-resisting, free from extraneous odour after immersion, without precipitate, surrounding will not be produced secondary pollution.
Further, aforementioned water reserve also includes: the plantation soil layer for planting floatingleaved plant being positioned on water storage module, utilizes the floatingleaved plant can pollutant in purifying rainwater further.
Preferably, aforementioned plantation soil thickness is 5-15cm, and described floatingleaved plant is beaverrot.
Of the present utility model have the beneficial effect that miniature reservoir of the present utility model can be used for save urban rainwater, a large amount of rainwater-collectings are stored rather than is directly discharged into pipe network, reduce flood peak pressure, alleviate the discharge pressure of city planting ductwork, water reserve is conducive to rainwater infiltration, water source can be laid in, it is ensured that the hydrological characteristics of natural environment is recovered while recharge of groundwater；And, this miniature reservoir floor space is little, can be in conjunction with the practical situation flexible design of subdistrict greening, utilize cobblestone and the interception of water plant, purification can effective purifying rainwater, store rainwater can be used in water sprinkling path, green area irrigation, vehicle cleaning etc., it is achieved that after rainwater-collecting again with, saved great lot of water resources, the light hydropenic problem of China can be made up to a certain extent, there is good Social benefit and economic benefit.
