Description

Pavement structure for sponge city
Technical field
The invention belongs to sponge urban infrastructure technical fields, and in particular to a kind of road surface knot for sponge city Structure.
Background technique
The construction in sponge city, it is important to can absorb water, permeable " sponge in city ".City sponge depends on city sea Continuous " matter " and " amount ".Expand metropolitan sponge amount, is the key that one of sponge urban construction.If urban area will be accounted for About 30% Hard base layer (road, square etc.) is changed to can be permeable, then, the soil layer below these Hard base layers is just Rainwater can be obtained, the cavernous body in city can be become, can increase 30% cavernous body in city, just so as to improve city soil property.
Nowadays in the construction of urban road, the construction of surface layer is the hard surfacing of cement or pitch compacting, hard road The laying in face is difficult in the arriving in rainy season effectively by rain penetration into underground, and there is a large amount of ponding on road surface, influences Pedestrian passes through, and especially in the driving process of vehicle, will increase braking distance, and pavement reflecting when night running is easy to happen thing Therefore.
Summary of the invention
The present invention solves the technical problem of:A kind of pavement structure for sponge city is provided, it is existing to solve Sponge city road storage capacity it is poor, enough water can not be adsorbed, the present invention has water storage effect good and water suction effect The good feature of fruit, simple structure and reasonable design are conducive to promote the use of.
In order to solve the above technical problems, the technical scheme is that:A kind of pavement structure for sponge city is provided, Including coating, planting soil layer, filter layer, reservoir bed, impervious barrier and base, the coating is located at the planting soil layer Top, the planting soil layer is located at the top of the filter layer, and the filter layer is located at the top of the reservoir bed, described Reservoir bed is located at the top of the impervious barrier, and the impervious barrier is located at the top of the base;
The filter layer includes metalling, fine sand layer and geotextile layer, and the metalling is located at the top of the fine sand layer, The fine sand layer is located at the top of the geotextile layer;
The base is that multiple arched supports are closely coupled;
The coating with a thickness of 20-30cm, the planting soil layer with a thickness of 30-50cm, first protection Layer with a thickness of 15-25cm, the filter layer with a thickness of 20-40cm, the metalling with a thickness of 10-20cm, it is described thin Layer of sand with a thickness of 10-20cm, the geotextile layer with a thickness of 1-5cm, the reservoir bed with a thickness of 20-40cm, it is described Impervious barrier with a thickness of 10-20cm.
Further say, the coating with a thickness of 25cm, the planting soil layer with a thickness of 40cm, described first Protective layer with a thickness of 20cm, the filter layer with a thickness of 30cm, the metalling with a thickness of 15cm, the fine sand layer With a thickness of 15cm, the geotextile layer with a thickness of 3cm, the reservoir bed with a thickness of 30cm, the impervious barrier with a thickness of 15cm。
It further says, the reservoir bed is the mixture of rock wool, fine sand and coarse sand.
It further says, the coating is gravel.
It further says, the base is that the arched support of multiple concretings is closely coupled.
It further says, the height of the arched support is 50-100cm.
Beneficial effects of the present invention are as follows:
The water storage effect for the pavement structure for sponge city that the present invention designs is good and the good advantage of soaking effect, in this way It can effectively restore, recharge of groundwater, maintain belowground ecosystem balance, prevent urban waterlogging and road surface from collapsing;And it is several layers of For arch support structures are arranged, sound construction, design rationally, are conducive to promote the use of.
