Technical Field
The utility model relates to a drainage road surface drainage retaining structure belongs to road construction technical field.
Background
With the continuous development of economy in China and the continuous acceleration of urbanization process, urban inland inundation phenomena begin to occur frequently. In China, the urban waterlogging disaster is caused not only by difficult drainage or geographical factors, but also by the fact that the water area of an urban rainwater pipe network is reduced due to the damage to the ecological environment in the urbanization process, the hard pavement is continuously increased, and the drainage pressure of the urban rainwater pipe network is increased, so that the urban waterlogging is caused.
The drainage asphalt pavement is characterized in that a pavement structure layer is paved by an asphalt mixture with larger gaps, and the general void ratio can reach 18-25%. When raining, rainwater can enter the interior of the road surface through the material gaps and then is transversely discharged along the road cross slope or continuously seeps into the interior of the middle and lower surface layers. In actual engineering, after carrying out appropriate rivers passageway and drainage facility design, drainage bituminous paving can absorb rapidly and remove the road surface moisture when the rainfall, store simultaneously, moisturizing is in order to alleviate city "heat island effect" when high temperature in summer, help alleviating urban drainage pipe network pressure, be favorable to promoting sustainable development's city green space construction, can also improve bituminous paving's anti rutting ability in summer, extension road surface life, reduce drainage system's construction cost by a wide margin, improve driving safety and travelling comfort and reduce the noise that the vehicle travel.
However, the existing drainage pavement has a single structure, only the upper layer is replaced by asphalt mixture, the drainage surface layer and the lower structure are not tightly combined, and no drainage ditch exists or a rainwater pipeline is used for drainage; if the rainfall is too large or the discharge speed is too slow, the rainwater can stay in the gap of the road surface for a long time, the service capacity of the drainage road surface is influenced, and the road surface structure can be damaged to cause dispersion.
