A kind of landscape wetland system adopting reuse water to be applied to underground garage top
Technical field
The utility model relates to a kind of landscape wetland system adopting reuse water to be applied to underground garage top.
Background technology
Along with the raising of people's living standard, car also come into more and more the common people other, and along with the increase of car, garage, community area is also increasing, and the area in garage, community increases, and causes the green coverage of community correspondingly to reduce.In order to increase the green coverage of community, people at top, garage planting plants, because top, garage pedosphere is general thinner, retaining and water retention capacity poor, in order to meet the requirement of plant-growth, the frequency of man-made irrigation increases, this increases manual labor amount, meanwhile, greening water also increases, and further increases the maintenance cost of subdistrict greening.On the other hand, natural rainwater but directly drains into municipal rain system when not being fully used.
Utility model content
The utility model is for the deficiencies in the prior art, a kind of landscape wetland system adopting reuse water to be applied to underground garage top is provided, by rain sewage collecting, disposal and utilization, realize supply and the self-equilibrating certainly of community underground garage top greening water, ecological, environmental protective, have community scenery concurrently simultaneously, increase green coverage.
For this reason, the utility model is by the following technical solutions:
A kind of landscape wetland system adopting reuse water to be applied to underground garage top, comprise the growing area (1) being located at garage end face, it is characterized in that: described growing area (1) has the gradient downward-sloping from outside to inside, its end connects landscape wetland pond (2), spilling water wall (3) is set between growing area (1) and landscape wetland pond (2), growing area (1) comprises plantation layer (11) and water proof stopping area (12) from top to bottom, floating plant district (21) is formed in described landscape wetland pond (2), emergent district (22) and hydrobiont district (23), filtering layer (24) and water reservoir (25) are formed successively on the bottom in landscape wetland pond (2), water reservoir is provided with water pump and rising pipe in (25).By growing area is arranged to the downward-sloping gradient, and its end connects landscape wetland pond, wetland pond is utilized to collect and process rainwater, through the acting in conjunction of wetland plant, wetland ecotourism and filtering layer, rainwater is purified, water after purification, that meet greening water supply standard is stored into water reservoir, for supplying growing area plant water sources.
Further, described filtering layer (24) comprises fine sand layer (24a), zeolite layer (24b) and metalling (24c) from top to bottom successively.Rainwater adsorbed and filters, removing the impurity in water and microorganism.
Further, described growing area (1) forms xerophyte district (13), mesophyte district (14) and hygrophyte district (15) from outside to inside successively, described spilling water wall (3) is a little more than plantation layer (11), the top of spilling water wall (3) is provided with garbage barrier net (31), also be provided with waterways (32) in the below of garbage barrier net (31), the water inlet of waterways (32) is provided with filtering net (32a).Arrange the plant of different qualities according to the landform on top, garage, improve the surviving rate of plant, scientific and reasonable; Spilling water wall, waterways can get rid of unnecessary rainwater during, excessive rainfall comparatively large at rainfall amount.
Further, described landscape wetland pond (2) is rounded, and growing area (1) is around whole outer circle setting Monday of landscape wetland pond (2).Take into account the greening of community and attractive in appearance.
Therefore, the utility model can increase green coverage and the view area of community on the one hand, can realize supply and the self-equilibrating certainly of community underground garage top greening water on the one hand, ecological, environmental protective.

Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1-2, employing reuse water of the present utility model is applied to the landscape wetland system on underground garage top, comprise the growing area 1 being located at garage end face, as shown in Figure 1, growing area 1 has the gradient downward-sloping from outside to inside, the end of growing area 1 connects landscape wetland pond 2, spilling water wall 3 is set between growing area 1 and landscape wetland pond 2, growing area 1 comprises plantation layer 11 and water proof stopping area 12 from top to bottom, plantation layer 11 is for planting plants, and water proof stopping area 12 is for protecting underground garage jacking row, prevent moisture, root system of plant damages it, simultaneously, also the rainwater being beneficial to top, garage flows by the predetermined flow direction.
Floating plant district 21, emergent district 22 and hydrobiont district 23 is formed in landscape wetland pond 2, filtering layer 24 and water reservoir 25 are formed successively on the bottom in landscape wetland pond 2, and filtering layer 24 comprises fine sand layer 24a, zeolite layer 24b and metalling 24c from top to bottom successively.The rainwater on top, garage is collected in landscape wetland pond 2, and is processed by the aquatic animals and plants system in wetland pond, and the rainwater after process filters through filtering layer again, makes rainwater meet the standard of greening water, and saves in water reservoir 25.Be provided with water pump and rising pipe in water reservoir 25, the water pump in water reservoir 25 gone out, for the irrigation of vegetation in community by water pump and rising pipe.
Growing area 1 forms xerophyte district 13, mesophyte district 14 and hygrophyte district 15 from outside to inside successively, described spilling water wall 3 is a little more than plantation layer 11, garbage barrier net 31 is provided with above spilling water wall 3, also be provided with waterways 32 in the below of garbage barrier net 31, the water inlet in waterways 32 is provided with filtering net 32a.In growing area, form more arid growing area, intermediate species plant and comparatively moistening growing area according to the distance from landscape wetland pond 2, correspondingly, select drought life, neutrality and hygrophyte to plant, the survival rate of plant can be improved, reduce manual maintenance cost; Unnecessary rainwater when spilling water wall, waterways can get rid of, excessive rainfall comparatively large at rainfall amount, is suitable for the place that the rainwater such as the south of the River are more.
In the present embodiment, landscape wetland pond 2 is rounded, and growing area 1 is around whole outer circle setting Monday in landscape wetland pond 2.Certainly, landscape wetland pond 2 and growing area 1 also can adopt other shape, determine according to community scenery and Greening Design.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
