Description

发明名称:海绵城市用模块化道路雨水径流处理系统及处理方法 技术领域  Title of Invention: Modular Road Rainwater Runoff Treatment System and Processing Method for Sponge City Technical Field
[0001] 本发明属于海绵城市建设低影响幵发技术领域, 具体涉及一种海绵城市用模块 化道路雨水径流处理系统及处理方法。  [0001] The invention belongs to the technical field of low impact bursting of sponge city construction, and particularly relates to a modular road rainwater runoff processing system and a processing method for a sponge city.
背景技术  Background technique
[0002] 近年来, 随着中国城市化的快速发展, 地下水位以惊人的速度下降, 城市内涝 已成为人们关注的热点问题, 而道路交通系统是内涝出现的高发地带。 过去城 市对雨水追求"一排了之", 城市排水标准偏低和雨水利用系统缺乏是造成资源成 为灾害的主要原因。 随着"海绵城市" LID (Low Impact Development) 理念的提 出, 建立"渗、 滞、 蓄、 净、 用、 排"六位一体的新型城市道路雨水处理系统成为 治理城市内涝顽疾的重要手段。  [0002] In recent years, with the rapid development of urbanization in China, the groundwater level has dropped at an alarming rate. Urban shackles have become a hot issue of concern, and the road traffic system is a high-risk zone where guilt arises. In the past, the city pursued “one row” of rainwater. The low urban drainage standards and the lack of rainwater utilization systems are the main causes of disasters. With the concept of LID (Low Impact Development), the establishment of a new urban road rainwater treatment system that is “infiltration, stagnation, storage, net, use and platoon” has become an important means to control the ills of the city.
[0003] 在构建符合 LID理念的城市排水系统中, 现有规划设计理念是优先利用植草沟 、 渗水砖、 雨水花园、 下沉式绿地等 "绿色 "措施来组织排水, 以"慢排缓释"和" 源头分散"控制为主, 更多的实际处理方式是将雨水径流通过路缘石的雨水导入 口直接进入路缘石分隔的道路绿化带或者街边绿地。 这类做法虽实现了源头分 散, 但初期道路雨水径流中携带漂浮垃圾、 砾石、 泥沙等固态物质与重金属离 子、 病原体、 有机污染物等, 直接排入不仅容易堵塞雨水导口与排水口, 还会 影响植物生长。 除此之外, 在降雨频繁或暴雨吋期, 雨水容易在路面上形成高 速水流, 会严重冲击并破坏道路绿化或者街边绿地的植被。 再者, 路缘石不仅 施工步骤繁琐, 还需要综合考虑天气、 温度等外在因素, 其次, 运输途中易缺 棱掉角, 影响施工进度与美观。  [0003] In the construction of the urban drainage system in line with the LID concept, the existing planning and design concept is to preferentially use the "green" measures such as planting ditch, seepage brick, rain garden, and sinking green space to organize drainage, with "slow release" The "and" source dispersion is dominated. The more practical treatment is to pass the rainwater runoff through the rainwater inlet of the curbstone directly into the road greenbelt or the streetside greenbelt separated by the curb. Although such practices have achieved a divergent source, the initial road rainwater runoff carries solid materials such as floating garbage, gravel, and sediment, and heavy metal ions, pathogens, and organic pollutants. Direct discharge is not only easy to block the rainwater inlet and outlet, It also affects plant growth. In addition, during frequent rains or heavy rains, rainwater can easily form high-speed water on the road, which can seriously impact and destroy the greening of roads or the vegetation of street greens. Moreover, the curb stone is not only complicated in construction steps, but also needs to consider external factors such as weather and temperature. Secondly, it is easy to lack corners during transportation, which affects the construction progress and appearance.
[0004] 因此, 为了贯彻海绵城市 LID理念及其做法, 很有必要研发设计一种道路雨水 径流处理系统, 有利于城市良性水文循环, 提高对道路径流雨水的渗透、 调蓄 、 净化、 利用和排放能力, 从而利于解决地下水位降低的问题。  [0004] Therefore, in order to implement the sponge city LID concept and its practices, it is necessary to develop and design a road rainwater runoff treatment system, which is conducive to urban benign hydrological cycle, improve the penetration, storage, purification, utilization and Emission capacity, which is conducive to solving the problem of lower groundwater level.
