The invention relates to the technical field of tunnel construction, in particular to a dismantling device and dismantling method for a temporary outfitting piece on the pipe top of an immersed pipe, and the dismantling device comprises a transfer frame which comprises a supporting assembly and a hanging ring fixed to the supporting assembly; the embedded slideway is arranged on the central axis of the top of the immersed tube; the pulley assembly comprises a fixed pulley, a movable pulley block and a pull rope; the transferring frame is transferred to the position, close to a temporary outfitting piece, of the pre-embedded sliding way, the outfitting piece is hoisted to the transferring frame through the chain block, the second end of the pull rope is pulled, the pull rope is turned through the fixed pulley and the movable pulley set, the first end of the pull rope drives the movable pulley set to move, and the movable pulley set is pulled to move. Therefore, the transfer frame is driven to move to the centralized stacking area along the pre-buried sliding way. The labor force is greatly reduced, and the construction efficiency is obviously improved; and the cost of the pre-embedded slideways, the pulley assemblies and the transfer frame is low, and the pulley assemblies and the transfer frame can be repeatedly used, so that the cost is further reduced.

    本发明涉及隧道施工技术领域,尤其涉及一种沉管管顶临时舾装件的拆除装置及拆除方法,拆除装置包括转运架,包括支撑组件以及固定在支撑组件上的吊环;预埋滑道,设置在沉管管顶的中轴线上;滑轮组件,包括一定滑轮、一动滑轮组和拉绳;转运架转移至预埋滑道靠近临时舾装件的位置,手拉葫芦将舾装件吊装在所述转运架上,拉动所述拉绳的第二端,所述拉绳经过所述定滑轮以及所述动滑轮组的转向,所述拉绳的第一端带动所述动滑轮组移动,从而带动所述转运架沿所述预埋滑道移动直至所述集中堆放区;大幅度减少了人工劳动力的付出,显著提升施工效率;预埋滑道、滑轮组件、以及转运架成本较低,且滑轮组件和转运架可重复使用,进一步降低了成本。
