Background

The sponge city is characterized in that the city can be like a sponge, has good elasticity in the aspects of adapting to environmental changes, coping with natural disasters and the like, absorbs water, stores water, seeps water and purifies water when raining, releases and utilizes the stored water when needed, is constructed according to the principles of ecological priority and the like, combines natural approaches and artificial measures, furthest realizes the accumulation, permeation and purification of rainwater in urban areas on the premise of ensuring the safety of urban drainage and waterlogging prevention, promotes the utilization of rainwater resources and ecological environment protection, and is characterized in that in the construction process of the sponge city, the systematic nature rainfall, surface water and underground water are comprehensively planned, and the water recycling links such as water supply, drainage and the like are coordinated, and the complexity and the long-term property are considered.

The sponge city needs good permeability on ground in the construction, and for this reason ground can adopt the water permeability material in the construction, nevertheless the rainwater permeates to the ground end after, is difficult to discharge, and in case the rainwater is too much, the road surface also is difficult to carry out hydrophobic, can cause the rainwater to be difficult to the problem of discharging equally, has proposed a rainwater infiltration structure for the sponge city for this reason.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a sponge is rainwater infiltration structure for city possesses the advantage of the rainwater of discharging, has solved and can adopt the water permeability material in the construction, however the rainwater permeates to the end of the land after, is difficult to discharge, and in case the rainwater is too much, the road surface also is difficult to carry out hydrophobic, can cause the rainwater equally to be difficult to the exhaust problem.

The utility model provides a following technical scheme: the utility model provides a rainwater infiltration structure for sponge city, includes the rammed earth layer, be provided with waterproof barricade on the rammed earth layer, the rubble layer that is located waterproof barricade one side has been laid on the rammed earth layer, the rubble layer upper berth is equipped with the filter layer, the filter layer upper berth is equipped with the planting soil layer, be provided with a plurality of catch basins that are located waterproof barricade opposite side on the rammed earth layer, the catch basin upper berth is equipped with the isolation layer, the isolation layer upper berth is equipped with the gravel layer, the gravel layer upper berth is equipped with the concrete that permeates water, the concrete upper berth.

Preferably, a plurality of perforated pipes are arranged inside the crushed stone layer.

Preferably, waterproof films are laid on the ramming layer and the water storage tank.

Preferably, be provided with the water pipe between the catch basin, and the water pipe that is close to waterproof barricade department runs through waterproof barricade and extends to in the rubble layer.

Preferably, the waterproof retaining wall divides the ground into a planting area and a road area.

Compared with the prior art, the utility model discloses possess following beneficial effect:

this rainwater infiltration structure for sponge city, divide into planting district and road surface district with ground through waterproof barricade, prevent the rainwater mutual interference of two district infiltration, plant the district, the rainwater is through planting the soil layer and filtering the earth that carries through the filter bed, filter most impurity through the metalling again, then the rainwater gets into and discharges in the perforated pipe, and the road surface district, the rainwater gets into the intraformational filtration of sandstone through the brick that permeates water and the concrete that permeates water, later the rainwater passes the isolation layer and collects in the cistern, and the water pipe is with every cistern intercommunication, make the rainwater in the cistern arrange to the intraformational gravel in planting district, discharge from the perforated pipe at last, reach the mesh of discharge rainwater, and as long as timely discharge the rainwater, the situation of ponding just can not appear on ground.
