高空大跨径软弱地基固定式提升站设计与施工关键技术

Design and Key Construction Technology of Fixed Lifting Station Under High Altitude and Large Span and Soft Foundation Working Conditions

结合现场实际工况,主要从施工成本、安全性、可操作性等方面进行对比分析,设计出一种适用于高空、大跨径、软弱地基、有限空间等工况条件下的固定式提升站,并成功应用于温州瓯江北口大桥钢混组合梁安装施工。

Combined with the actual working conditions of the site,mainly from the construction cost,safety,operability and other aspects of the comparative analysis,a fixed lifting station which is suitable for high altitude,large span,soft foundation,limited space and other working conditions is design,the lifting station is successfully applied to installation construction of composite girder of Wenzhou Oujiang Beikou Bridge.
