摘要：道路雨水径流含有大量污染物质，且初期雨水径流带来的污染物负荷最为严重。初期雨水径流污染不能仅靠分流制排水系统，由于分流制排水系统也存在一些缺陷，而且目前国内很多城市旧城区合流制的分流改造效果也不尽理想。因此，应改变传统的规划设计理念和施工技术，进一步改进与创新，通过新技术、新方法和新理念，达到解决城市排水系统和初期雨水径流污染问题。目前各种初期雨水控制设施都有其限制因素，本文提出一项“路沿式排水槽”新技术, 替代传统雨水管道，道路雨水通过“路沿式排水槽”的导流沟和过滤层净化过滤,有效控制道路初期雨水径流污染问题，降低雨水径流污染负荷，同时解决旧城区合流制的分流改造问题，达到控源截污，源头治理之目的。

Abstract： Road stormwater runoff contains a large number of pollutants, and the initial rainfall runoff is the most serious pollutant load. The initial rainwater runoff pollution cannot only depend on the drainage system, the drainage system has some defects, and many domestic old city reconstruction effect of confluence shunt is not ideal. Therefore, we should change the traditional planning design and construction technology, further improvement and innovation, through new technology, new methods and new ideas to solve the problem of city rainwater runoff pollution and early drainage system. The initial rainwater control facilities has its limitations, this paper proposes a new technology of road along the drainage groove, to replace the traditional rainwater pipes, rainwater through the edge of the road drainage trough "diversion ditch and filter layer filtration, road rainwater runoff pollution control, reduce rainwater runoff pollution at the same time load, solve the old city reconstruction system shunt confluence, achieve pollutant source control, the purpose of source control.
Key words： at the beginning of the road design of rainwater drainage drainage luyashi drainage ditch
