现浇预应力混凝土连续箱梁是高速公路桥梁工程中常采用的一种结构型式,施工方法主要以移动模架法和满堂支架法为主,但当山区地势陡峭、跨沟跨河、相邻墩台高差较大时,其应用受到一定限制。依托实际工程,在对比分析现浇箱梁不同施工方法优缺点基础上,探讨了山区复杂地形条件下现浇箱梁贝雷梁自行式工作平台的安装技术,总结了适于不同地形及施工环境的三种工作平台的拼装方法,可为山区公路类似现浇箱梁施工提供参考和借鉴。
Cast-in-place prestressed concrete continuous box girder is often used in expressway bridge engineering, a type of construction, the construction method is mainly to move the shelf method and full house stent method, but when the mountainous terrain steep, across the ditch across the river, adjacent piers When the height difference is large, its application is subject to certain restrictions. On the basis of comparative analysis of the advantages and disadvantages of different construction methods for cast-in-place box girder, this paper discusses the installation technology of Bei Liang self-propelled work platform with cast-in-place box girder under complex terrain in mountainous area, The assembling method of the working platform can provide reference and reference for the similar construction of mountainous highway box girder.
