Cantilever scaffold for well wall in open caisson and construction method of cantilever scaffold
The invention provides an open caisson inner well wall overhanging scaffold and a construction method thereof. The construction method comprises the steps of installing pre-buried high-strength bolts, installing prefabricated steel guide rails, assembling a supporting structure of the overhanging scaffold, installing the supporting structure of the overhanging scaffold, erecting the overhanging scaffold, conducting open caisson well wall construction and dismantling the overhanging scaffold. The overhanging type scaffold comprises a prefabricated steel guide rail, and the prefabricated steel guide rail is fixed to the inner well wall of the open caisson through high-strength embedded bolts and high-strength nuts. Supporting assemblies in sliding connection are arranged in the prefabricated steel guide rails, and steel pipe hoops are arranged on the upper surfaces of the supporting assemblies. The construction method can be suitable for the open caisson construction process, one-time erection can be completed, the repeated erection and disassembly process of a floor type scaffold in the open caisson sinking earth cutting process is reduced, the construction progress is accelerated, the construction period is shortened, the labor input is reduced, and therefore the engineering cost is saved.
本发明提供一种沉井内井壁悬挑脚手架及其施工方法，施工方法为安装预埋高强度螺栓—安装预制钢导轨—拼装悬挑脚手架的支撑结构—安装悬挑脚手架支撑结构—搭设悬挑脚手架—沉井井壁施工—拆除悬挑脚手架。悬挑式脚手架包括预制钢导轨，预制钢导轨通过高强度预埋螺栓和高强度螺母固定于沉井内井壁；预制钢导轨内设置滑动连接的支撑组件，支撑组件上表面设置钢管抱箍。本发明能够适用于沉井施工过程，能够一次搭设完成，减少了落地式脚手架因沉井下沉挖土过程中重复搭设和拆卸的过程，加快了施工进度，压缩了施工工期，减少人工投入，从而节省了工程成本。
