上海在日前完工的人行道改造中,首次使用了全新的生态透水道路系统,道路像人体呼吸一样,雨天可以吸收雨水,夏天可以“排汗”。专家表示,一般的行道砖中纤维是密闭的,这种新型行道砖则可以渗水,雨水可以通过地砖直接渗透入土壤,使雨水转为地下水,回升了地下水位,可以缓解因地下水流失而导致的地表沉降现象,同时也有利于排解积水。高温季节,这个系统还能反向蒸发水气,缓解城市的热岛效应。
For the first time in its reconstruction of the sidewalk completed recently, Shanghai used a new ecological water-permeable road system that absorbs rainwater in rainy days and “perspiration” in the summer as the human body breathes. Experts said that the common road brick fiber is airtight, this new type of brick can be seepage, rainwater can penetrate directly into the soil through the floor tiles, so that rainwater to groundwater, the groundwater level rise, can alleviate the loss due to groundwater Surface subsidence phenomenon, but also conducive to resolve the water. During the hot season, this system also reverses evaporation of moisture to ease the urban heat island effect.
