Description
Technical field
The present invention relates to road construction technical fields, and in particular to a kind of roadway rainwater collection system in sponge city.
Background technique
In city, road is important infrastructure, and urban road would generally be laid to bituminous pavement, asphalt road mask
Have that flatness is good, durable and fluid-tight feature.Wherein, the advantages of impermeability is both bituminous pavement and disadvantage,
On the one hand it ensure that roadbed is not collapsed by rainwater excessive erosion；On the other hand, when rainfall is excessive, a large amount of rainwater can only
Drained by city sewer, and cannot be absorbed and be stored by urban surface, water resource is unable to get reasonable utilization.
With the proposition of sponge city concept, building, there is the road of rainwater collecting function to become one of developing direction.Such as
The Chinese utility model patent that Authorization Notice No. is CN206529670U, authorized announcement date is 2017.09.29 discloses a kind of sea
The road drainage system in continuous city, and specifically disclose road drainage system and include porous pavement and be set to porous pavement two sides
Road tooth diversion channel, porous pavement is equipped with purifying layer, and purifying layer is communicated with the first reservoir, and the first reservoir is communicated with first and overflows
Water pipe and first uses water pipe, and road tooth diversion channel is communicated with the second reservoir, and road tooth diversion channel is equipped with away from porous pavement side plants
By filter layer, the second reservoir is equipped with second with water pipe and the second overflow pipe being connected with vegetation filter layer upper end；Vegetation mistake
Filtering layer bottom is equipped with the pervious bed being connected to the first reservoir.Wherein, purifying layer include the haydite layer set gradually from top to bottom,
Fine sand layer and active carbon layer, the first reservoir are located at the lower section of active carbon layer.
When meeting with the weather conditions of heavy rainfall, a part of rainwater on road surface will by porous pavement and purifying layer into
Enter into the first reservoir, while having in the tooth diversion channel of the road another part rainwater Hui Cong and the second reservoir is entered by drainpipe
In, it is collected by the first reservoir and the second reservoir road pavement rainwater.But the first reservoir is set to full impregnated water route
The underface in face, it cannot be guaranteed that playing sufficiently stable supportive to road, after rolling use for a long time, road surface is likely to occur
The problem of collapsing；Moreover, specially the second reservoir of setting increases entire for collecting the rainwater being discharged into from the tooth diversion channel of road
The complex degree of structure and construction cost of roadnet.
Summary of the invention
To solve the above-mentioned problems, the object of the present invention is to provide a kind of road rainwater collecting systems in sponge city
System, is likely to occur collapsings to solve the road surface of roadnet in the prior art, and structure is complicated and construction cost is high asks
Topic.
The technical solution of the roadway rainwater collection system in sponge city of the invention are as follows:
The roadway rainwater collection system in sponge city includes the road pervious bed and base course set gradually from top to bottom, institute
It states and is folded with waterproof sealing between road pervious bed and base course, the waterproof sealing is located at the two sides difference in road width direction

The underground storage structure of aquaporin connection；
The two sides that the road pervious bed is located at road width direction are respectively equipped with spilling water channel, the spilling water channel connection
The space more than upper surface of road pervious bed, and the drainage channel respectively with the sky more than upper surface of the waterproof sealing
Between be connected to the spilling water channel.
The utility model has the advantages that roadway rainwater collection system adds the structure of waterproof sealing, road using road pervious bed, base course
The upper surface of pervious bed is the road surface of road, and rainwater on road surface, which can pass through under road pervious bed, to be seeped to waterproof sealing, then is passed through
Waterproof sealing carries out lower infiltration rainwater to be guided to drainage channel；If encountering heavy rainfall weather, the seepage velocity of road pervious bed
It is not enough to empty rainwater, then road surface Man Shui directly can be drained into drainage channel, drainage channel by the spilling water channel of both sides of the road
Lower infiltration rainwater can be collected and road overflows water, uniformly drain in underground storage structure, reduce the construction number of underground storage structure
Amount and project amount, underground structure simply can reduce difficulty of construction and construction cost；Moreover, underground storage structure is located at base course
Outside, ensure that the stable and firm of entire road basis, avoid the underface that underground storage structure is directly arranged in road and
It causes road to be in vacant state, prevents road after rolling use for a long time, the problem of road surface collapses occur.
Further, in order to ensure lower infiltration rainwater can be drainage ditch completely into drainage channel, the drainage channel,
The both sides of the edge that the waterproof sealing is located at road width direction extend respectively to the close waterproof sealing center of drainage ditch
Side inner wall.
Further, in order to improve waterproof sealing to the lower diversion effect for seeping rainwater, the upper surface of the waterproof sealing is
The arcuate surface low in intermediate high two sides along road width direction.
Further, in order to guarantee the waterproofness of waterproof sealing, the waterproof sealing is emulsified asphalt slurry seal.
Further, the water penetration and skid resistance of road pervious bed, the road pervious bed include permeable anti-in order to balance
Slip layer and water-permeable filter layer, the water-permeable filter layer are located at the downside of permeable skid layer；The permeable skid layer uses OGFC system
At the water-permeable filter layer is the concrete layer with gap.
Further, in order to meet the wearability of permeable skid layer, the thickness of the permeable skid layer be 2cm extremely
10cm。
Further, in order to guarantee the structural strength of concrete layer, the thickness of the concrete layer be 10cm extremely
30cm。
Further, in order to reduce the cost of road construction, the base course is cement stabilized macadam base.
Further, road overflows outside of the water flow to road in order to prevent, and the road pervious bed is located at road width side
To two sides be respectively equipped with curb, the curb is arranged in juxtaposition along link length direction and the spilling water in the spilling water channel enters
Mouth is opened on the side wall on close road surface of the curb.
Further, in order to play the role of quickly and effectively desanding, institute to the road surface Man Shui being expelled directly out through spilling water channel
The spilling water exit close to the spilling water channel for stating drainage ditch is equipped with riffler.
Further, in order to ensure that the clean-up performance of the rainwater stored in underground storage structure, the underground storage knot
Structure is set to the lower section of drainage ditch, and the inside of underground storage structure is equipped with section dirty removal of impurities structure for filtering rainwater.
Further, in order to give full play to the effect of rainwater itself, the underground storage structure is equipped with intake pipe
