Urban road rainwater regulation and storage system

Abstract

The invention discloses an urban road rainwater regulation and storage system. The system comprises a water permeable pavement (1), and a grass planting furrow (2) and a water permeable side pavement (3), wherein the grass planting furrow (2) and the water permeable side pavement (3), and the water permeable pavement (1) are sequentially arranged in parallel; the water permeable pavement (1) comprises a foundation layer (11) and a water permeable asphalt surface layer (12), which are laid in sequence from bottom to top; the water permeable side pavement (3) comprises water permeable bricks (31) laid on the surface of the water permeable side pavement (3). According to the rainwater regulation and storage system disclosed by the invention, the water permeable pavement, the water permeable side pavement and the grass planting furrow between the water permeable pavement and the water permeable side pavement form the enhancing effects of purifying, filtering, regulating and storing ground surface rainwater, and the rainwater is effectively controlled and utilized, so that a sponge city is easily constructed; meanwhile, the rainwater regulation and storage system also has an afforestation landscape effect.

Description

technical field [0001] The invention relates to the technical field of municipal engineering, in particular to an urban road rainwater regulation and storage system. Background technique [0002] With the significant acceleration of urbanization in my country and the continuous expansion of urban scale, the area of ​​urban green space has gradually decreased. Most of the green areas, wetlands, ditches and other areas that originally had the function of water conservation have evolved into hardened ground, resulting in street flooding and reduced groundwater storage when the city faces heavy rainfall. It can only rely on municipal pipe network drainage, resulting in frequent waterlogging disasters Runoff pollution is serious. Statistics show that more than 360 cities across the country have suffered from waterlogging, and one-sixth of them have been submerged for more than 12 hours and the depth of waterlogging has exceeded half a meter. Cities such as Beijing and Jinan have...
