海绵城市理念在公路项目中的设计实例研究

Research on the Design Practice of Sponge City Concept in Highway Project

通过对公路项目在城市中设置海绵设施,满足海绵城市的建设要求。本实例海绵城市设计主要的情况包括:(1)本岛侧道路区域非机动车道、人行道设计为透水路面,道路设置环保型雨水口;(2)本岛侧环岛东路互通区域设置雨水花园、雨水湿地、透水铺装等设施;(3)翔安侧在桥下设置雨水花园,非机动车道、人行道设计为透水路面;(4)翔安侧滨海东大道互通区域设置雨水湿地、透水路面等设施。通过对海绵设施的复核计算,设计的海绵设施能够满足厦门海绵城市的建设要求。

The design practice of sponge city concept is based on the Xiamen Second East Passageway project. The construction requirements of sponge city is satisfied by setting sponge facilities in urban highway projects. The designs of sponge city in this project practice include:(1) permeable pavement is set for non motorized lanes and sidewalks in the road area on the side of the island, and environmental friendly rainwater inlets are set on the road;(2) rainwater garden, rainwater wetland, permeable pavement and other facilities are set in the interchange area of Huan dao East Road on the side of the island;(3) at Xiang’an side, a rainwater garden is set under the bridge, and permeable pavement is set for non motor vehicle lanes and sidewalks;and(4) the interchange area of Binhai East Avenue on the side of Xiang’an is equipped with rainwater wetland, permeable pavement and other facilities. Through the review and calculation of sponge facilities, the design of sponge facilities in Xiamen Second East Passageway Project can meet the construction requirements of Xiamen sponge city.
