The box urban road rainwater of ecological water accumulation utilizes system, it is characterized in that: comprise trashrack, water storage device, impervious barrier and planting soil, described impervious barrier is arranged on bottom surface and the side of described water storage device, and described planting soil is on described water-tight device; Described trashrack is arranged on road surface, by water storage device described in retaining channel connection; Described planting soil plane is higher than road plane.
For preventing that upper strata planting soil is scattered, enter water storage device, between described planting soil and described water storage device, be equipped with geotextiles.
Described planting soil side has been built road kerb by laying bricks or stones.
Described impervious barrier is one deck waterproof film structure sandwiching between two-layer geotextiles, and the surface of described water storage device is lower than road surface.
Described water storage device is PP plastics rainwater-collecting modules.
Described planting soil thickness is 20-40cm.
Described planting soil plane is higher than road plane 5-15cm.
The box urban road rainwater of ecological water of the present utility model accumulation utilizes system, is arranged at centre and the edge of urban road, bottom solum compacting, and water storage device is imbedded in road.Rainwater by trashrack by pollutant filterings such as leaf, rubbish, oils and suspended solids, rainwater after purification enters water storage device, water storage device is rainwater storage, because the capillarity of planting soil absorbs the water in water storage device, completed accumulation and the utilization of rainwater.
The beneficial effect that the utility model is obtained:
1. the box urban road rainwater of ecological water accumulation utilizes system simulation " underground water and the surface water " principle of supply mutually, utilize the efficient water storage effect of PP plastics rainwater-collecting module and " capillarity " of planting soil that the rainwater of collecting is carried out to accumulation and utilization, system has the function of automatic adjusting, the automatic conversion of " holding " and " use " can be realized, workload and the input of follow-up manual maintenance can be reduced.
2. the box urban road rainwater of ecological water accumulation utilizes system outside to take the layering of double-deck geotextiles and waterproof film to lay, and can effectively solve that rainwater infiltrates road and the problem of the roadbed damage that causes.
3. the box urban road rainwater of ecological water accumulation utilizes that system adopts blocks dirty measure and seepage control measure can fully guarantee the water quality of the rainwater of accumulation, and prevents that pollutant is with rain infiltration, polluted underground water.
4. the water storage filler that water storage device adopts is PP plastics rainwater-collecting modules, has good compressive property, can effectively increase the application life that the box urban road rainwater of ecological water accumulation utilizes system.
5. the box urban road rainwater of ecological water accumulation utilizes system upper surface higher than road surface, even compared with heavy rainfall in the situation that, still draining is smooth and easy, can effectively solve waterlogging problem.
6. the box urban road rainwater of ecological water accumulation utilizes system to select suitable tree, grass seeds according to local weather and soil regime, drop into less, compliance is stronger.

In figure: 1 geotextiles; 2 waterproof films; 3 water storage devices; 4 planting soils; 5 trashracks; 6 retaining passages; 7 road kerbs.
The specific embodiment
Below by the specific embodiment, further set forth the utility model.
The box urban road rainwater of ecological water accumulation utilizes system to be arranged on urban road central authorities and edge, and the high nearly low natural grade that is 1-1.5% of preferred road great distance.As shown in Figure 1, the box urban road rainwater of ecological water accumulation utilizes the compacting of system bottom solum, and water storage device 3 is set thereon, the bottom surface of water storage device 3 and side are laid one deck geotextiles 1 from inside to outside successively, one deck waterproof film 2 and another layer geotextiles 1, water storage device 3 tops are provided with planting soil 4, between planting soil 4 and water storage device 3, be equipped with one deck geotextiles 1, water storage device 3 adopts PP plastics rainwater-collecting module water storage, its hole can store rainwater, trashrack 5 is concordant with road surface, convenient for cleaning and utilize the gradient on road surface that rainwater is imported to trashrack 5 places, trashrack 5 adopts steel design.Between trashrack 5 and water storage device 3, by retaining passage 6, be connected, retaining passage 6 is concrete structure, and retaining passage 6 has been accelerated the speed that rainwater enters water storage device 3.The side of planting soil 4 has been built road kerb 7 by laying bricks or stones.Wherein tamp soil thickness: 10cm; Water storage device 3 height: 80cm, wide: 150cm; Planting soil 4 thickness: 30cm, exceeds road surface: 10cm; Trashrack 5 is wide: 10cm; Retaining passage 6 height: 30cm, wide: 10cm.
The dynamic equilibrium mechanism that the box urban road rainwater of ecological water accumulation has utilized system simulation natural groundwater water storage environment and surface water and underground water transforms mutually, finally reaches the automatic accumulation of rainwater, supplies with the dynamic equilibrium pattern of green plants growth.As shown in Figure 2, rainwater on road surface can pass through other approach, for example evaporation is consumed, most of rainwater is by trashrack 5, isolated the pollutant in rainwater, the rainwater of high-quality enters PP plastics rainwater-collecting module by rainwater storage by retaining passage 6, rainwater is the equal of underground latent water layer in collection module, the rainwater of storage is supplied with plant growth by the capillarity of upper strata planting soil 4, reaching automatic supply plant needs the object of water, amount of precipitation is large, PP plastics rainwater-collecting module holds after full water, because the box urban road rainwater of ecological water accumulation utilizes system to exceed 10cm than road surface, rainwater can be discharged by pavement drainage facility, can not utilize system to damage to the box urban road rainwater of ecological water accumulation, guaranteed the stability of its impact resistance and operation.
Water storage device 3 is PP plastics rainwater-collecting modules, and it has good compressive property, can effectively increase the application life of ecological water tank system.PP plastics rainwater-collecting module void content is 90%-95%, and water space is larger, can store fully water source, for the growth of green plants provides sufficient water source, for " automatically regulating " of follow-up ecological cistern system provides basis; And not being subject to the impact of the things such as microorganism, bacterium and pitch, is a kind of good water storage facility.Between water storage device 3 and upper strata planting soil 4, lay one deck geotextiles 1, prevent that upper strata planting soil 4 is scattered into water storage device 3, and do not affect the capillarity of planting soil.Stored the water storage device 3 of high-quality rainwater, the green plants that can plant upward by the capillarity of planting soil 4 without precipitation arid time supplies water, oneself regulates output, reach the dynamic equilibrium of rainwater accumulation and utilization and automatically adjust, saved the irrigation water consumption of green plants, especially in semiarid zone, Precipitation distribution is uneven, and the weather that the normal form with heavy rain occurs, the box urban road rainwater of ecological water accumulation utilizes the advantage of system and practicality just to seem particularly evident.
