Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1~Fig. 5, a kind of rainwater for mountain area sponge urban construction described in the utility model recycles System, including infiltration system, cistern 2, detention system, cleaning system 3 and the irrigation system connected by drainage system, wherein Drainage system is mainly interconnected and is formed by a plurality of infiltration pipeline 7, discharge pipe line 8 and artificial drainage groove.Since mountain area has There is physical features height difference, can be flowed down automatically in the local excessive rainfall close to mountain area side slope 200, if not arranging rainwater quickly Walk, 200 rainwater of side slope can be caused to accumulate, cause the natural calamities such as landslide.In the position construction infiltration system pair close to side slope 200 Rainwater is quickly permeated, and infiltration system includes building oozes porous pavement 1 and infiltration Water Plaza 4 in 200 side of side slope, wherein Oozing porous pavement 1 includes road main body 11 and positioned at the lawn 10 of 11 both sides of road main body, in road main body 11 and lawn 10 Between be equipped with drainage groove, and road main body 11 includes impermeable stratum 112, the infiltration water layer 111 being laid with successively from top to bottom, no The rainwater connected with drainage groove is equipped with pervious bed 112 and collects pipeline, when rainwater is waterproof by permeating the entrance of water layer 111 After layer 112, flow directly into drainage groove, on the one hand ground is protected, avoid excessive rainfall from damaging ground.Waterproof The lower section of layer 112 is also embedded with the infiltration pipeline 7 for collecting rainwater in soil, when the rainwater in soil exceedes the adsorption capacity of soil Afterwards, flowed out by the water seepage hole on pipeline 7 that seeps water, since infiltration pipeline 7 is connected with discharge pipe line 8, so that by drainage groove It is transported in cistern 2 and is stored with the rainwater in infiltration pipeline 7.Likewise, infiltration Water Plaza 4 is included from top to bottom successively The impermeable stratum 112 and infiltration water layer 111 of laying, are also embedded with for collecting rainwater in soil below impermeable stratum 112 Seep water pipeline 7, and rainwater is transported in cistern 2 by infiltration pipeline 7 again by discharge pipe line 8.General square can only be by rain Water penetration is into the soil of below ground, and not accounting for the water adsorption ability of soil has limit, and excessive moisture is be easy to cause Building depression, collapse and split, and can easily cause traffic paralysis in road surface stroke ponding.By seeping water, pipeline 7 can be by unnecessary water Point be collected, will not break can be in soil original content, on the one hand protect soil to be in natural humidity state, will not be due to Excessive rainfall causes surface gathered water, is not easy to walking and is on the other hand also recycled unnecessary moisture, improves water resource Utilization rate.
Cistern 2 can follow road together to build, and existing reservoir, lake etc. can also be used to collect rainwater.Cistern 2 In water can be discharged in dry days, by irrigation system by rainwater vegetation, lawn 10, for conserving water and soil.In the present embodiment In, a kind of prior purposes is, according to porous pavement 1 is oozed or that permeates Water Plaza 4 builds mode, landscape is built in side Rainwater is made full use of on green building as detention system, makes full use of water resource by pond.
Cleaning system 3 is equipped between cistern 2 and detention system, the water in cistern 2 is purified, is avoided stagnant Environmental pollution by water in water system, be unfavorable for landscape plant existence, wherein cleaning system 3 include be sequentially communicated sedimentation basin 31, Biological purifying tank 32, purification water pool 33, carry out preliminary sedimentation, by sludge etc. when the rainwater in cistern 2 enters in sedimentation basin 31 Precipitated, the water after precipitation is further cleaned into workable water into biological purifying tank 32, then in purification water pool It is collected in 33, purification water pool 33 is connected with detention system, so as to supplies water in detention system.Detention system includes The backwater wetland of artificial formula and greening backwater roofing 6, wherein backwater wetland are sunk type construction, including sinking meadow 51 and in grass The integrate draining pond 52 dug among ground, is embedded with the infiltration pipeline 7 connected with integrate draining pond 52 below sinking meadow 51, infiltration Pipeline 7 is also connected with discharge pipe line 8, is flowed back in cistern 2, so as to ensure the activity of the water in backwater wetland, will not produce dirt Dye, is viewed and admired beneficial to pedestrian.The infiltration tree well of sunk type can be set on greening backwater roofing 6, green plant is supported for planting water Thing, expands the usage range of purified water, makes full use of the rainwater in cistern 2.
Rainy day, rainwater is by oozing porous pavement 1, infiltration Water Plaza 4 is collected in cistern 2, then passes through cleaning system 3 Water purification is provided to artificial landscape pond, construction backwater wetland, greening backwater roofing 6, view and admire easy to pedestrian, build green building, symbol Implementation theory, dry days, moreover it is possible to irrigated by irrigation system vegetation, meadow etc. are protected in cyclization.The whole rainwater circulatory system pair Rainwater is collected, and is recycled, and fully rainwater is collected in the rainy day, prevents 200 excessive rainfall of side slope from causing to slide Slope etc., is also avoided that rainwater on road surface deposits, causes to have inconvenient traffic;Rainwater is made full use of to save water resource, protection fresh water money Source.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, can be to this The technical solution technical scheme is modified or replaced equivalently of utility model, without departing from the objective and model of technical solutions of the utility model Enclose, it should all cover among the right of the utility model.
