Abstract:
To realize a steel earth retaining material installation tool and a liner plate installation method capable of suitably installing a liner plate on a shaft wall while protecting the shaft wall of a shaft during excavation.SOLUTION: Since a shield material and a movable plate of the steel earth retaining material installation tool can slide relative to each other, by repeatedly installing steel earth retaining material installation tool on a wall of a shaft, joining a liner plate on the movable plate placed on a lower side of the shield material of the steel earth retaining material installation tool installed on a shaft wall, lowering the shield material along the shaft wall by its own weight while excavating the bottom of the shaft, releasing the movable plate and the liner plate and lowering the movable plate to the lower side of the shield material, and joining a new liner plate on the movable plate, the liner plate can be suitably installed on the shaft wall while protecting the shaft wall with the shield material of the steel earth retaining material installation tool.SELECTED DRAWING: Figure 1
