Description
技术领域 technical field
本发明涉及道路路面结构技术领域，特别涉及一种完全透水性复合式路面结构。 The invention relates to the technical field of road pavement structures, in particular to a completely water-permeable composite pavement structure.
背景技术 Background technique
在城市建设中，许多城市大量采用水泥混凝土、沥青混凝土等封闭地表，取代原有的土壤表面，对道路人行道、非机动车道等公共场所，也喜欢用整齐漂亮的石板材或水泥彩砖铺设。封闭地表在改善交通和道路状况、美化环境的同时，也对城市生态和气候环境产生显著的不利影响。 In urban construction, many cities use cement concrete and asphalt concrete to replace the original soil surface. For public places such as roads, sidewalks and non-motorized vehicles, they also like to use neat and beautiful stone plates or cement colored bricks. While improving traffic and road conditions and beautifying the environment, the closed surface also has significant adverse effects on urban ecology and climate.
其中，封闭地表由于逐步被阻水材料所硬化覆盖，水分难以下渗，降水很快成为地表径流，进入河道或者地下排水管道，从而形成了生态学上的“人造沙漠”。 Among them, the closed surface is gradually hardened and covered by water-blocking materials, making it difficult for water to infiltrate. Precipitation quickly becomes surface runoff and enters rivers or underground drainage pipes, thus forming an ecological "artificial desert".
封闭地表造成的不透水路面缺乏对城市地表温度、湿度的调节能力，雨水蒸发快，地表易干燥，扬尘污染重；且雨后水分快速蒸发，空气湿度大，使人感到闷热难耐，而后又异常干燥，从而产生气象学上的城市“热岛效应”。 The impermeable pavement caused by the closed surface lacks the ability to adjust the temperature and humidity of the urban surface, the rainwater evaporates quickly, the surface is easy to dry, and the dust pollution is heavy; after the rain, the water evaporates quickly and the air humidity is high, making people feel hot and unbearable, and then abnormal Dry, resulting in meteorological urban "heat island effect".
封闭地表造成的不透水路面阻止了地下水补给路径，加之城市地下水的过量抽取，导致城市地下水位越来越低，引发地面沉降，沿海地区还会导致海水倒灌，从而造成地质学上的“漏斗型”地下水位。 The impermeable pavement caused by the closed surface prevents the groundwater recharge path, coupled with the excessive extraction of urban groundwater, the urban groundwater table is getting lower and lower, causing land subsidence, and coastal areas can also lead to seawater backflow, resulting in a geological "funnel" "Water table.
封闭地表造成的不透水路面还使城市中用来调节小气候的地表植物生长困难，有的树木甚至因根系缺水死亡、倒伏，从而丧失生态作用。 The impermeable pavement caused by the closed surface also makes it difficult for the surface plants used to adjust the microclimate in the city to grow. Some trees even die and fall due to lack of water in the root system, thus losing their ecological functions.
因此，亟需提出一种具有良好透水性的路面结构以增加了城市的透水透气空间，达到调节城市小气候、保持生态平衡的良好效果。 Therefore, it is urgent to propose a pavement structure with good water permeability to increase the water-permeable and breathable space of the city, so as to achieve the good effect of adjusting the urban microclimate and maintaining ecological balance.
