内环线高架桥是上海市重大建设项目,长达29km的高架桥将是城市的快速干道,而桥下有非机动车道和人行道,并设停车场.因此桥面渗漏水不仅会腐蚀钢筋,影响高架桥安全和耐久性,对桥下车辆和行人造成危害,还会影响城市的美观,因此上海市内环线工程建设指挥部对高架桥桥面防水专门立题进行研究.从1991年4月开始,我们参加该课题的研究,历时两年多已完成该项目的科研和试验任务,并通过高架桥指挥部组织的专家评审验收.1993年在一期5.5km高架桥面进行了施工应用,效果很好.
Inner Ring Viaduct is a major construction project in Shanghai. The 29km-long Viaduct will be the city’s rapid trunk road with non-motorized and sidewalks under the bridge and a parking lot. Therefore, the seepage of the bridge deck will not only erode the reinforcement and affect the viaduct Safety and durability of vehicles and pedestrians in the bridge, but also affect the appearance of the city, Shanghai Inner Ring project construction headquarters to study the viaduct bridge deck waterproofing special subject. From April 1991 onwards, we participate The research of the subject, which lasted for more than two years, has completed the scientific research and test tasks of the project and was evaluated and accepted by experts organized by the viaduct command department.In 1993, the construction application was carried out on a 5.5km viaduct deck, and the effect was very good.
