移动模架的主梁长度一般会长于桥梁跨径约1/4,进行整体横移时,必须要越过桥梁的已施工完成的下部结构,才能移位到桥梁的另一幅。在泽蒙—博尔察大桥滩桥施工过程中,通过自主创新,首创绕行法移动模架主梁横移施工技术,在狭小的空间范围内成功地将移动模架主梁整体转幅,克服了当地设备资源限制,避免移动模架主梁再次拼装和预压而耗费时间,加快了施工进度,并总结了施工要点及适用条件,为整体横移技术在类似边界条件下的应用提供借鉴。
The length of the main girder of the movable formwork will generally be longer than about 1/4 of the span of the bridge. When carrying out overall traversing, it is necessary to cross the under construction completed substructure of the bridge to be able to be displaced to another one of the bridges. During the construction of beach bridge in Zemun - Borna Bridge, through the independent innovation, the first bypassing method moves the main beam of the movable formwork and traverses the construction technology, transforms the main beam of the movable formwork entirely in a narrow space, It overcomes the limitations of local equipment resources, avoids re-assembling and pre-pressing of the main girder of the movable mold frame, takes time, speeds up the construction progress, summarizes the construction points and applicable conditions, and provides reference for the application of the whole traverse technology under the similar boundary conditions. .
