The main structure of the vertical shaft integral mobile metal formwork is a single-seam annular knot formed by connecting multiple arc-shaped metal plates, and several layers of rings are connected to form a rigid formwork with only one contraction port. The formwork support demoulding action is driven by a pneumatic hydraulic pump to drive a group of telescopic hydraulic cylinders and realized by a manual hydraulic valve. The lower blade foot installed at the lower end of the main formwork can prevent concrete from running and realize the downward walling method. The formwork has the characteristics of high rigidity, high overall strength, and small deformation after multiple disassembly and assembly. The hydraulic contraction mechanism can flexibly demould and erect the formwork. Therefore, it is widely used in the walling of coal mines and metal mines.
