摘要
结合预应力混凝土空心板的调坡顶升改造工程,对城市立交匝道桥梁调坡顶升改造施工关键技术进行初步探讨,从顶升反力系统施工、支撑系统施工、同步顶升三方面对匝道桥顶升改造施工工艺进行阐述。
The key technologies of slope adjustment and reconstruction of urban city overpass are discussed in the light of the reconstruction project of prestressed concrete hollow board,and the construction technology of city overpass is expounded from three aspects: the construction of the top rise recoil system,the construction of the support system,and the synchronization of the top rise.
