Description

Natural permeable quarrying paving structure for sponge city

Technical Field

The utility model relates to a sponge city technical field specifically is a natural structure of mating formation of quarrying that permeates water in sponge city.

Background

At present, urban roads are mostly laid in a waterproof way, the waterproof road surface seriously hinders the infiltration of rainwater, so that the rainwater can be discharged through a road surface and the flood discharge capacity is very limited, and when strong rainfall weather occurs, large-range water accumulation occurs on the road surface; meanwhile, the impermeable road surface reduces the humidity of urban air, so that an urban heat island effect is formed, and the existence of the impermeable road surface also destroys a normal water ecological circulation system in the environment and seriously influences the normal growth of urban vegetation. In the rainfall process, rainwater carries a large amount of urban surface pollutants into the natural water body on the surrounding surface, secondary pollution is generated, and the pollution degree of the natural water body is increased.

Along with the country impels ecological sponge city construction vigorously, the road of permeating water to pave receives attention increasingly, and the road that permeates water accelerates rainwater infiltration and discharges, can effectively reduce the peak discharge, prevents and treats urban waterlogging, can purify the rainfall runoff simultaneously and pollute. However, the prior permeable asphalt pavement paving material has larger porosity, so that the material is loose in early stage and low in strength, is easy to sink and crack under the direct action of long-term vehicle load, and has poorer pavement durability.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome current defect, provide a natural stone facing structure that permeates water in sponge city, increased the bituminous paving's that permeates water bearing strength, avoid the damage to the bituminous paving that permeates water through the rational distribution of bituminous paving and ordinary bituminous paving simultaneously, can effectively solve the problem in the background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a natural stone quarrying structure that permeates water in sponge city, includes permeable asphalt pavement and ordinary asphalt pavement, permeable asphalt pavement lays in the intermediate position and the both sides of road, and ordinary asphalt pavement lays between two permeable asphalt pavement, ordinary asphalt pavement sets up for the slope, has laid ordinary asphalt layer under the ordinary asphalt pavement, has laid permeable asphalt layer under the permeable asphalt pavement, and permeable concrete has been laid to permeable asphalt layer lower extreme, and the rubble basic unit has been laid to the concrete lower extreme that permeates water, and the ground basic unit has been laid to rubble basic unit lower extreme.

As the utility model discloses a preferred technical scheme, rubble basic unit intermediate position is equipped with the drainage french drain, and the drainage end of drainage french drain is linked together with the underground drainage canal that sets up at the road both ends.

As an optimized technical scheme of the utility model, the drainage french drain sets up for inclining to both sides from the centre.

As an optimal technical scheme of the utility model, the geotechnical cloth has been laid between rubble basic unit and the ground basic unit.

Compared with the prior art, the beneficial effects of the utility model are that: this natural stone quarrying structure that permeates water in sponge city is through laying pervious concrete in proper order at the bituminous layer lower extreme that permeates water, rubble basic unit and foundation bed, the bearing strength and the steadiness of the bituminous paving that permeates water have been increased, cross laying through pervious bituminous paving and ordinary bituminous paving makes the vehicle normally travel on ordinary bituminous paving, the rainwater absorbs the rainwater along the ordinary bituminous paving that permeates water that the slope set up to the bituminous paving that flows to both sides when raining, the effectual damage of having avoided the bituminous paving that permeates water, the durable usability of the road of mating water has been improved.
