Method and apparatus for concrete sheathing and timbering work in underground structure

Abstract

Abstract PURPOSE:To simplify the process of concrete sheathing and timbering work as well as eliminate the downtime of the work by a method in which the lower timbering work is constructed by using formworks for bottom and sides, hung down from the upper concrete sheathing and timbering work already constructed, and the hanging places of the formworks are orderly switched to lower places. CONSTITUTION:A bottom formwork 7 is set through a load receiving black 6 on the upper part of a hanging member 3, a side formwork 8 is integrally provided on one side of the bottom formwork 7 in an inclinable manner, and the bottom formwork 7 and the hanging member 8 are thrust from above at the lower end of a hanging rope 1 having detachable and vertically movable hooks to make up a formwork device to be hung down. The bottom formwork 7 and the side formwork 8 are hung down from the upper concrete sheathing and timbering work 15 already constructed to construct the lower timbering work 16, and the hanging places of them are orderly switched to the lower timbering work to construct the subsequent timbering work.
