HUANG QUNGUANG / TANG XIAOJUN / GAO CE / WANG HONGYI / WANG GANG / ZHU XUESONG

The invention discloses a method for dismantling a Bailey beam support across a road and a river, and relates to the method for dismantling the Bailey beam support. A problem that an existing Bailey beam support system is not easy to disassemble is solved. The method comprises the specific steps of determining a lengthening length of a distribution beam during installation according to specific sizes of longitudinal damage blocking facilities such as the installed maximum Bailey beam group, an on-site pier body and the like; installing a Bailey beam transverse moving power device at a lengthened end of the distribution beam, and realizing that a stainless steel plate wraps and makes contact with the Bailey beam at the position of the distribution beam under assistance of a jack; synchronously controlling an electric control hoist to realize transverse movement of the Bailey beam group, and transversely moving the Bailey beam group out of a longitudinal dragging damage blocking unit ofthe Bailey beam group such as a bridge pier and the like; moving the Bailey beam group to a longitudinal dragging rolling shaft through cooperation of the jack; longitudinally dragging the Bailey beamgroup; and repeating transverse movement, longitudinal dragging and dismantling construction of the Bailey beam group. The invention belongs to the field of constructional engineering.

一种用于跨路、跨河流贝雷梁支架拆除方法，它涉及一种贝雷梁支架拆除方法，具体涉及一种用于跨路、跨河流贝雷梁支架拆除方法。本发明为了解决现有贝雷梁支架体系不易拆除的问题。本发明的具体步骤为根据安装的最大贝雷梁组及现场墩身等纵向挡害设施的具体尺寸，确定安装时分配梁的加长长度；分配梁加长端安装贝雷梁横向移动动力装置，并通过千斤顶协助作业实现不锈钢板包裹接触分配梁位置贝雷梁；同步控制电控葫芦，实现贝雷梁组的横向移动，横移至桥墩等贝雷梁组纵向拖拉挡害单位之外；通过千斤顶配合将贝雷梁组移动至纵向拖拉滚轴上；进行贝雷梁组纵向拖拉；重复贝雷梁组横向移动、纵向拖拉、拆除施工。本发明属于建筑工程领域。
