XUE CHANGLI / PEI XUEFENG / CHE PING / LIU ZHIGUO / SUN WEIGUO

The invention provides a remote-control adjustable steel box girder cantilever construction channel and a construction method thereof. The construction method comprises the following steps of lofting calculation, size adjustment, steel box girder construction, construction channel construction and use of the construction channel so as to construct a cantilever. The channel is simple in structure and does not need additional investment; a lower support and an upper support are combined, supporting is stable, and construction is accurate without shaking; a remote controller drives the construction channel to transversely move, construction continuity is effectively guaranteed, manpower is saved, and construction efficiency is improved; the size of the construction channel can be adaptively adjusted according to the size change of the cantilever, and universality is high.

提供一种遥控可调节式钢箱梁挑臂施工通道及其施工方法，包括如下步骤：放样计算‑调节尺寸‑钢箱梁施工‑施工通道施工‑施工通道的使用进而对挑臂施工。本发明结构简单，无需另行投入；下支撑和上支撑结合，支撑稳定，施工精确无晃动；遥控器驱动施工通道横移，有效保证施工连续性，节省人力，提高施工效率；根据挑臂尺寸变化，可适应性调节施工通道尺寸，通用性强。
