Description
Technical field
The utility model relates to urban road engineering technical fields, and in particular to a kind of sponge urban water-through road structure.
Background technique
Traditional urban road surfaces are generally made of impermeable materials such as asphalt or cement concretes, road surface row
Water is realized by crown slope.However, the rainwater within the scope of rainy day road surface cannot be laterally rejected to outside the range of road surface in time, make
At surface gathered water；Lead to skid resistance of pavement seriously and reduce, vehicle driving is easily drifted about, and traffic safety is influenced, be easy to cause friendship
The generation of interpreter's event.In addition, making waterproof pavement changes the original hydrology ecological environment in city, municipal drainage system is increased
The pressure of system easily causes the generation of urban waterlogging in the case of heavy rain.
Road surface is the important carrier of city space, and solves the problems, such as an important ring for urban waterlogging.With ground surface material
Continuous development, porous pavement for solve urban waterlogging provide feasibility.Porous pavement is mixed using the biggish pitch of voidage
Material or cement concrete are closed, road surface has preferable permeability, can reduce road table ponding with vertical drainage；Simultaneously by Lu Biaoyu
Water is discharged into sub-surface or roadbed, and city cavernous body storage road table water serves as in roadbed or base, and the Urban Natural hydrology is promoted to follow
Ring mitigates the pressure of sewerage system.
Porous pavement can effective solution urban waterlogging, adjust urban heat land effect, it has also become construction sponge city weight
Want approach.Current porous pavement is directed to pavement or non-motorized lane mostly, and the load of effect is smaller.Friendship on car lane
Logical load is larger, and porous pavement will not only meet drainage requirement, it is also necessary to have enough bearing strengths.If car lane using
Road table rainwater is discharged into roadbed by full porous pavement, is be easy to cause roadbed softening intensity insufficient, is led to pavement destruction.Such as patent
A kind of permeable road structure based on sponge the idea of the city that CN 207176431U is announced, although can be realized road surface drainage storage
Water function, but roadbed is easy to happen the use on harm influence road surface.Thus.Design it is a kind of can Quick drainage, water storage it is motor-driven
Lane line structure, while roadbed, pavement strength can not also be influenced, for solving urban waterlogging, realizing that sponge city is very necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of sponge urban water-through road structure, which can be in not shadow
The rainwater within the scope of road surface is effectively excluded in the case where ringing motor vehicle road surface bearing strength, reduces urban waterlogging, promotes city certainly
Right Hydrology circulation.
The purpose of this utility model is realized through the following technical scheme.A kind of sponge urban water-through road structure,
Including car lane, non-motorized lane, greenbelt, roadbed, kerbstone and kerb cushion block；It is characterized by: car lane is from upper
Successively including surface layer, Drainage Base, semi-rigid type base and underlayment in drainage surface layer, draining under and；Drainage Base and semi-rigid
Sealing is provided between property base.
Non-motorized lane successively includes permeable surface layer, porous base course and permeable underlayment from top to bottom.Non-motorized lane
Impervious barrier layer is provided between permeable underlayment and roadbed.
Greenbelt includes planting soil, and planting soil is embedded with drainpipe, and drainpipe periphery is equipped with rubble filter layer, rubble mistake
Filtering layer periphery is equipped with permeable anti-filter geotextiles；It drains tube wall and is equipped with large number of inlet opening, drainpipe and existing draining
System connectivity.The drainpipe being arranged in greenbelt is PVC drain pipe, so that road has enough drainabilities, works as greening
Water level with interior rainwater no longer rises when reaching the permeable base layer height of non-motorized lane, but is discharged into draining system by drainpipe
In system.The metalling of making and permeable anti-filter geotextiles around PVC drain pipe, preventing planting soil from entering PVC drain pipe causes to arrange
Water is not smooth.
Be equipped with fine sand layer between the semi-rigid type base of planting soil and car lane, draining underlayment, planting soil and roadbed it
Between be equipped with fine sand layer, above fine sand layer and planting soil bottom is equipped with anti-seepage geotextile.The anti-seepage geotextile of setting, for preventing
The rainwater being only stored in greenbelt, which enters roadbed, influences subgrade strength.The fine sand layer of making below geotextiles avoids applying
The rupture of work process anti-seepage geotextile.
Kerbstone and kerb cushion block are made of water-permeable cement concrete, and voidage is greater than 20%.Car lane with it is non-maneuver
Rainwater in lane is discharged into greenbelt by permeable road kerb, permeable kerb cushion block, and greenbelt undertakes road surface as reservoir
Water storage function mitigates sewerage system pressure.
Sponge urban water-through road provided by the utility model, can be in the case where not influencing road surface bearing strength effectively
The rainwater within the scope of road surface is excluded, the traffic safety on car lane road surface and non-motor vehicle road surface is improved, effectively solution city
Waterlogging problem promotes Urban Natural Hydrology circulation.
The water discharge technology principle of the utility model is sketched: car lane uses half permeable pavement structure, drainage surface thickness
Spend 40mm, voidage 15~20%, surface thickness 80mm, voidage 18~25% in draining, Drainage Base thickness 100mm, gap
Rate 20~25%；The moisture storage capacity on car lane road surface are as follows: 4 × 15%+8 × 20%+10 × 25%=47mm.Non-motorized lane is using complete
Permeable pavement structure, permeable surface thickness 180mm, voidage 10~15%, porous base course thickness 200mm, voidage 20~30%,
Underlayment 150mm, voidage 30~40%, non-motor vehicle road surface moisture storage capacity are as follows: 180 × 10%+200 × 20%+150 × 30%=
103mm.As it can be seen that car lane and non-motorized lane have enough water spaces, rapid discharge path table rainwater during having heavy rain
Ability.The sealing being arranged between car lane porous base course and semi-rigid underlayment, avoid rainwater penetrate into semi-rigid type base and
The intensity for reducing car lane underlayment and roadbed, ensure that the intensity and durability on road surface.
Compared with existing porous pavement, the utility model have it is following the utility model has the advantages that the utility model car lane
Using semi-transparent water channel line structure, road surface gathered water can quickly, be effectively discharged by road surface vertical drainage, rainwater is avoided to enter half
Rigid base, underlayment and roadbed cause to soften, and improve pavement strength and durability；Greenbelt is as reservoir, in not shadow
Rainwater is collected in the case where ringing subgrade strength, the rainwater within the scope of road surface is discharged into greenbelt, is reducing sewerage system pressure
Urban ecology water circulation is promoted while power.The ponding within the scope of road surface effectively can be quickly discharged in the utility model, improve
Road traffic safety reduces urban waterlogging, promotes Urban Hydrologic system circulation.
