Description
Technical field
The present invention relates to surface drainage technical field, it is specifically related to a kind of multi-level environment-friendly type road draining and leads
Water system.
Background technology
Current when raining for convenience, road surface is generally that centre is raised slightly, and the both sides near curb are compared in the middle of road surface
The structure for slightly declining, is so to ensure that the road location of road surface center section does not have ponding as far as possible.Existing ground
Draining is all by collector nozzle and the sewer pipe draining for being arranged on roadside.The ratio that rains is larger, precipitation speed exceedes
During the permeation rate of seepy material, rainwater is failing to go down from the pervious bed infiltration of road surface center section then can be along road surface
The gradient flow at the curb in roadside, form ponding, and can be cumulative, or even curb is covered, by strong influence
The normal traffic and walk of vehicle.
On the other hand, with urban construction, perfect, the urban ground coverage rate more and more higher of road network.Current city road
Use closely knit, impermeable material making more on the road surface of road, urban ecological environment is faced with some distinct issues：1) during rainy season
A large amount of rain drainages will greatly increase the burden of sewerage system；2) table ponding in road splashes in the presence of driving vehicle, right
Nearby vehicle and pedestrains safety have a negative impact；3) closely knit, fluid-tight road surface lacks to urban surface temperature, the tune of humidity
Energy-conservation power, dust pollution weight；4) road surface prevents recharge of ground water path, makes in city for adjusting the ground flora of miniclimate
Growth is difficult, and tropical island effect is protruded.
Structure type being used current edge drainage system, by longitudinal drainage pipe or rhone and horizontal outlet pipe, most more
Terminating enters municipal drainage pipeline.Using this kind of road surface drainage method, drainage asphalt pavement address only rainy day surface not ponding,
Driving is safer, reduces the problem of dust pollution, but does not solve the subject matter in urban ecological environment simultaneously：1) underground is reduced
Water, recharge of groundwater resource；2) burden of sewerage system is reduced；3) improve urban surface temperature, humidity, improve Urban Thermal
Circulation, alleviates tropical island effect.
