交通枢纽道路雨水控制与利用技术研究

Study on Control and Utilization Technology of Road Rainwater in Transportation Hub

针对交通枢纽雨水内涝问题,从高架道路、地下道路与地面道路角度,分别提出雨水控制与雨水利用的技术措施,以保证枢纽道路服务能力。对于高架道路,采用了排水性沥青路面、雨水浅层蓄渗技术,以减少路表径流;通过雨水处理与利用装置,实现了雨水循环利用。对于地下道路,可采用自流排水、调蓄排水与抽升排水,同时可选择排水交通复合型隧道防洪。对于地面道路,可采用透水铺装、生态植草沟等措施进行雨水控制。

Aiming at the rainwater waterlogging problem of transportation hub, the article proposes the technical measures of rainwater control and rainwater utilization from the angles of elevated road,underground road and ground road to guarantee the service capacity of hub road. The drainage asphaltpavement and rainwater shallow-layer storage infiltration technology is used to reduce the surface runoff of elevated road. The cycle utilization of rainwater is realized by the rainwater treatment and utilization device.The self-flow drainage, storage drainage and pumping lift drainage can be used for the underground road.Also the drainage and traffic combined tunnel can be selected for flood control. The measures of permeable paving and ecological grass ditch can be taken to control rainwater of ground road.
