Description

Road surface drainage structure

Technical Field

The utility model relates to a based on sponge city theory, relate to town road technical field, specifically be a road surface drainage structure.

Background

The sponge city construction emphasizes that the 'green' measures such as grass planting ditches, rain gardens, sunken greenbelts and the like are preferably utilized to organize drainage, and the 'slow drainage and slow release' and 'source dispersion' control are taken as main planning and designing concepts, so that flood disasters cannot happen in a large range in the whole city macroscopic state, when the weather of short-time heavy rainfall occurs, the phenomena of submerging and waterlogging still exist in local low-lying areas in the city, the problems of urban waterlogging, ponding and the like are easily caused, and a great deal of inconvenience is brought to passing vehicles and pedestrians.

The existing road surface drainage system mostly adopts a mode of arranging drainage channels at two sides of a roadbed, water outlets are arranged at two sides of the roadbed, but when the drainage system is positioned at a low-lying position of a city, the drainage channels are blocked due to waterlogging or heavy rain, accumulated water cannot be timely discharged, and a great number of potential safety hazards are brought to the city.

Disclosure of Invention

The utility model discloses it is anticipated to provide a road surface drainage structure to solve urban road surface drainage problem.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a pavement drainage structure comprises a base layer, a water guide assembly, a baffle and a water seepage layer which are sequentially arranged from bottom to top; the water guide assembly comprises a water guide plate and a vertical plate, the water guide plate is laid on two sides of the base layer in the width direction and is V-shaped; a plurality of vertical plates are vertically fixed on the water guide plate, and a water guide channel extending along the inclined direction of the water guide plate is formed between the adjacent vertical plates; the baffle covers the upper part of the vertical plate, the water seepage layer is laid above the baffle, and the baffle is provided with water seepage holes.

The beneficial effect of this scheme does:

1. can discharge urban road surface rainwater fast. When there is ponding road top, ponding passes through the infiltration layer infiltration road below to on the infiltration hole through the baffle flows to the water deflector, based on the guide of water deflector, make rivers flow downwards to the ponding ditch through the water guide channel and discharge away through the ponding ditch, do benefit to and discharge away the ponding on ground fast, in order to avoid the phenomenon of local flooding, waterlogging, can eliminate because the potential safety hazard that ponding leads to. And because whole road surface can both permeate ponding, water guide plate and ponding ditch of flow direction below compare other drainage structures and carry out the drainage from the both sides on road surface, and drainage ability is limited, and this design can in time discharge more ponding from the road surface in urban waterlogging or torrential rain.

Because whole road surface all can the infiltration drainage, so water guide channel from the top down rivers can be bigger and bigger, take this kind of connected mode, not only can increase the intensity of structure, the connecting plate can not block water guide channel's rivers moreover. Because the closer to the middle of the road surface, the larger the distance between the connecting plate and the water guide plate is, the more and more unblocked water flow of the water guide channel from top to bottom can be ensured.

Preferably, as an improvement, the bottom of the vertical plate is provided with a water passing groove, and the water passing groove enables the adjacent water guide channels to be communicated, so that the water guide channels are mutually connected to form a water guide network, and the blockage of the water guide channels can be avoided.

Preferably, as an improvement, the lowest part of the water guide plate is fixedly connected with the edge of the ponding channel so as to directly guide the water flow into the ponding channel, so that the ponding can be discharged more quickly.

Preferably, as an improvement the water guide assembly further comprises a positioning column, the water guide plate is provided with a positioning hole, the positioning column penetrates through the positioning hole and is implanted into the base layer, so that the water guide plate can be more stably fixed on the base layer, the overall structure of the water guide plate is strengthened, the collapse problem of the water guide plate is avoided, and the service life of the device is prolonged.

Preferably, as an improvement the permeable layer includes a stone layer and a permeable concrete layer, the granularity of the stone layer is greater than on the baffle the aperture of the permeable hole, the stone layer is laid on the baffle, the permeable concrete layer is laid on the stone layer. The pervious concrete layer is also called porous concrete, sand-free concrete and pervious terrace; it is a porous light concrete which is prepared by mixing aggregate, cement, reinforcing agent and water, and does not contain fine aggregate. The pervious concrete is a cellular structure with uniformly distributed pores formed by coating a thin layer of cement slurry on the surface of coarse aggregate and bonding the thin layer of cement slurry, so that the pervious concrete has the characteristics of air permeability, water permeability and light weight. The granularity of the stone layer is larger, so that a large amount of materials of the base layer can be prevented from falling on the water guide plate, and the stone layer is also used as a barrier layer to further support and block the pervious concrete layer. The arrangement greatly enhances the drainage performance of the road surface, and no accumulated water remains on the road surface; and because other sundries are blocked and only accumulated water is discharged, the problem that the drainage capacity is reduced due to blockage of objects such as silt, garbage and the like in the conventional drainage mechanism is solved.

Preferably, as an improvement, a space is left between the bottom of the connecting plate and the water guide plate, so that accumulated water can flow down smoothly along the water guide plate without being blocked by the connecting plate.

Preferably, as an improvement the ponding canal has drainage channel, drainage channel and city main drainage pipeline intercommunication, can be faster with the ponding drainage pipeline that collects in the ponding canal, avoid ponding to stay in the polluted environment and the sanitary safety scheduling problem that the ponding canal brought for a long time.
