Description

一种海绵型透水路面结构A sponge-type permeable pavement structure

技术领域technical field

本实用新型涉及路面技术领域,尤其涉及一种海绵型透水路面结构。The utility model relates to the technical field of pavement, in particular to a sponge-type water-permeable pavement structure.

背景技术Background technique

随着城市化进程的加速,大量的硬质铺装改变了原有的生态本底和水文特征,一方面由于降雨不能及时下渗,地下水得不到及时补充,另一方面传统的城市排水体系却难以适应强降雨时形成的径流量洪峰,导致我国一些城市水资源短缺、水环境污染、洪涝灾害和生态环境恶化等问题已非常严重。雨水作为水循环系统的一个关键要素,在构建城市可持续水循环系统过程中发挥着重要作用。因此,如何对城市雨洪实施有效的控制利用已成为规划、建设、环保、水利等部门的一个重要课题。在海绵城市改造施工过程中,大部分道路改造措施为对道路基层进行储水层设置,部分埋设包裹透水土工布的开孔渗管接入市政管网,用于对积蓄过多的雨水进行过滤排放进入市政管网,这种渗、排方法仅起到对雨水排放的调节作用,未能发挥城市道路在海绵城市建设中的“滞、蓄、净、用”功能。With the acceleration of urbanization, a large number of hard pavements have changed the original ecological background and hydrological characteristics. On the one hand, due to the infiltration of rainfall in time, groundwater cannot be replenished in time. However, it is difficult to adapt to the flood peaks of runoff formed during heavy rainfall, resulting in serious problems such as water shortage, water environment pollution, flood disasters and ecological environment deterioration in some cities in my country. As a key element of the water circulation system, rainwater plays an important role in the process of building a sustainable urban water circulation system. Therefore, how to effectively control and utilize urban rainwater has become an important issue for planning, construction, environmental protection, water conservancy and other departments. In the process of sponge city reconstruction, most of the road reconstruction measures are to set up water storage layers on the road base, and some of the open-hole seepage pipes wrapped with permeable geotextiles are buried and connected to the municipal pipe network to filter the excess accumulated rainwater. When the discharge enters the municipal pipe network, this infiltration and drainage method only plays a role in regulating rainwater discharge, and fails to play the "stagnation, storage, purification and use" functions of urban roads in the construction of sponge cities.
