长春长北立交桥挂篮悬浇施工技术

摘要

长春长北立交桥为预应力混凝土连续刚构结构，采用挂篮悬浇施工。文章主要介绍了菱形挂篮的设计构造，挂篮拼装、挂篮预压、混凝土、钢筋、预应力施工等各施工阶段要点，为同类挂篮悬浇施工提供参考、借鉴。%Changchun north overpass is a prestressed concrete continuous rigid frame structure and the bridge was constructed by the form travelers with cantilever casting method. This paper introduces the design, structure, installation, the pre-pressure test of rhombic hanging basket, the concrete engineering,,thesteel bar engineering, and the prestress construction control points in each stage of the construction, providing reference for the construction of the same style bridges.
