摘要
Abstract
The top arch of the outlet gradient transition section of the diversion tunnel from the Yangtze River to the Han River is affected by adverse geological conditions,resulting in excessive settlement and non-conver-gence of the outlet slope of the tunnel.Due to the short period of the construction contract,if the traditional support plane template method is used to pour the edge and top arch,the construction period of the outlet sec-tion cannot meet the safety and schedule requirements of the contract.The article elaborates on the successful application of customized steel formwork trolley in the construction process of the concrete lining for the outlet gradient transition section of the diversion tunnel,which saves 7 days of construction time compared with the flat formwork.The appearance quality of the steel formwork concrete is better than that of the traditional flat large formwork lining for the transition section,which not only saves construction costs but also saves time for subsequent tunnel excavation.The experience and achievements obtained can be used as a reference for similar projects.关键词
