摘要
为研究生态敏感区公路施工期土壤侵蚀类型及特点,对生态敏感区公路施工期对水环境污染影响的途径进行研究,主要包括施工营地废水、施工场地废水、碎石场及隧道施工期产生的污水。提出了生态敏感公路施工期污染防治技术体系,构建了降雨资源化利用技术系统。基于降雨及径流形成规律,为满足路域植被生态需水量,对公路路域进行系统化研究设计,包括排水路面,盲沟灌溉网络、生态护坡与道路集水井、边沟设计,以及设置雨水径流蓄水排水净化设施。形成了一个完整的收集净化排蓄体系,包括雨水收集、净化、储蓄、节水灌溉等综合性系统化的技术体系削减路面径流,达到削减洪峰流量和降低径流污染以及降雨资源化集约利用的效果。
In order to study the types and characteristics of soil erosion during highway construction in ecological sensitive areas,the ways of influence on water environment pollution during highway construction in ecological sensitive areas are studied,mainly including waste water of construction camp,waste water of construction site,waste water of gravel yard and sewage of tunnel construction period.The technical system of pollution prevention and control during the construction of ecological sensitive highway is put forward,and the technical system of rainfall resource utilization is constructed.Based on the rule of rainfall and runoff formation,in order to meet the ecological water demand of vegetation in the road area,the systematic research and design of the road area are carried out,including drainage road surface,blind ditch irrigation network,ecological slope protection and road catchment wells,side ditch design,and the installation of rainwater runoff storage and drainage purification facilities.A complete system of collection,purification and storage,including rainwater collection,purification,storage,water-saving irrigation and other comprehensive and systematic technical system to reduce road runoff,to lower the peak flow and reduce runoff pollution and intensive use of rainfall.
