Abstract
A full-circle secondary lining inverted arch construction formwork system for a long-distance tunnel and a formwork transporting method adopt a customized steel formwork, a steel pipe support, and a turn buckle. The steel pipe support is arranged on the longitudinal main edge, and is provided between the longitudinal rails and a primary lining for supporting vertical buoyancy. The turn buckle is arranged between two sides of the formwork and a reserved steel bar for resisting horizontal load generated during asymmetric pouring. A cantilever gantry crane and a transportation flat car are used for formwork transporting, wherein travel rails of the cantilever gantry crane and the transportation flat car are integrated on the customized steel formwork, and there is no other rail. According to the present, the formwork has high strength and rigidity, the formwork system is simple.
