Urban Road Cross Section Eco-Design Based on Storage-Infiltration of Rainwater and Snowfall
In order to deal with the problem of flood disaster, water balance system damage and eco-environment deterioration for cities with development of urbanization in rain and snow area, an urban road cross section eco-design program with storage-infiltration utilization of rainwater and snowfall was proposed with the purpose of groundwater eco-replenishment, water conservation and snowfall stack, also ecological cross section form that can be used in practical engineering and enhancement of infiltration capability for sunken green space of urban road were put forward, and some effective anti-infiltration measures for subgrade and pavement were proposed to prevent the adverse action on urban road from the water in the sunken green space. The eco-design program increases storage-infiltration of rainwater and snowfall with holding the function of traffic organization, drainage and road landscape that belongs to the traditional urban road cross section, and it changed a single drainage system into a compositive storage-infiltration-drainage system. The eco-design program provided a basis and reference for urban road cross section eco-design in rain and snow area.
