Description
Technical field
The utility model relates to a kind of rainwater treatment system for road improvement ponding, and particularly a kind of road rain water is collected and drainage system.
Background technology
At present, the face of land of modern city is constantly covered by the building construction of steel concrete and fluid-tight road surface, because the motor vehicle road surface of portland cement concrete lacks the ability that absorbs heat and infiltration rainwater, and the People's Bank of China road surface has certain permeability, but the People's Bank of China road surface is higher than the motor vehicle road surface usually, therefore the ponding on motor vehicle road surface can only enter to city planting ductwork by the rain double-edged fine-toothed comb that is arranged on the roadside, a series of problems have been brought like this: (1), when concentrating rainfall in the short time, because a large amount of rainwater can only enter the river by drainage, have increased the weight of the burden of drainage greatly; Therefore, road ponding is not easy to discharge, and brings adverse effect for comfortableness and the safety of vehicles and pedestrians.(2), the fluid-tight road surface rainwater that allows to permeate the ground is less, causes groundwater table sharply to descend, industrial production and the modern life are doubled and redoubled phreatic extraction amount; Water deficient in the soil, anoxic, temperature rise etc., thereby directly influenced the health of urban vegetation, further aggravated arid, the water shortage problem in city.(3), fluid-tight road surface is difficult to and air carries out the exchange of heat and humidity, is easy to generate " heat island effect ", makes that the urban inner temperature is too high, causes climatic deterioration.
In order to solve above technical problem, Chinese patent CN102251456A discloses a kind of environmental permeable stratum structure.It comprises having infiltrative top layer and be positioned at the aquifer that top layer below can storage of water, is closely connected being folded with between top layer and the aquifer and can guides the permeable formation that oozes under the current.This permeable road structure makes the ponding on the road surface infiltrate into the aquifer of downside, realizes storm-water drainage and the collecting action on road surface; When being in the high temperature drying weather in the external world, the rainwater of collection can feed back in the face of land, plays and regulate humidity, reduces effects such as temperature.But this road structure can only be tackled the lower situation of amount of precipitation, and when running into strong convective weather, amount of precipitation is generally per hour more than the 50mm, and the moisture storage capacity of aquifer under the saturated situation, then can't realize continuing retaining in this structure, causes surface gathered water; Because existing city planting ductwork ubiquity design standard is low, the dilatation difficulty, the not enough problem of drainability between storm period even this reservoir is connected directly to city planting ductwork, also can cause the city planting ductwork rainwater to pour in down a chimney.Simultaneously, the laying structure of this road as can be seen, this laying structure can only be applied to underloading road surfaces such as sidewalk, and can not be applied on this heavily loaded road surface of motor road, and city ponding mainly is to cause because of the ponding by concrete mixer motor-car road surface, therefore, this technical scheme still can not prevent the motor vehicle surface gathered water effectively.
Because changing the motor vehicle road surface of original cement concrete still all is a very engineering of waste on material resources at manpower, therefore, the utility model has proposed a kind of road rain water and has collected drainage system at the motor vehicle road surface of existing cement concrete.
