为从源头上控制公路项目运营环境风险事故对城乡饮用水环境的影响,保护公路建设中跨越饮用水源二级区,防范危险化学品运输环境风险,以广西横县至宾阳二级公路工程竣工环保验收阶段,对桩号K5+374处跨越饮用水源保护区的清水河中桥增设的环保工程措施为例,阐述具体桥梁工程采用的饮用水源风险防范环保工程设计与投资费用,分析了环保工程设计的有效性。

For controlling the highway environment risk impact on urban and rural source of drinking water, pile K5+374 is taken as an example. It is an environmental engineering in drinking water protectionarea at the final completion and acceptance stage of the road engineering of secondary highway from Hengxian County to Binyang In this case, drinking water source risk prevention and environmental protection design and investment costs in bridge engineering are illustrated, and the effectiveness is analyzed at the meantime, aiming at providing reference and guidance to similar bridge project environmental impact assessment, environmental design and acceptance.
