Abstract
The invention discloses a tunnel secondary lining construction formwork trolley based on rectangular supports. The tunnel secondary lining construction formwork trolley comprises a rectangular supporting frame and a trestle assembly located at the bottom of the rectangular supporting frame, a formwork supporting system used for a formwork assembly for tunnel secondary lining construction is arranged on the outer side of the rectangular supporting frame, and the rectangular supporting frame and the trestle assembly are connected into a whole; the rectangular supporting frame comprises a left travelling beam, a right travelling beam, the rectangular supports and longitudinal connecting structures, the left travelling beam and the right travelling beam are arranged on the same plane, the rectangular supports are installed on the two travelling beams, the longitudinal connecting structures are connected among the rectangular supports, and travelling mechanisms are installed at the bottoms of the two travelling beams respectively; the trestle assembly comprises a trestle body located on the inner side of the rectangular supporting frame and a trestle hydraulic lifting device used for lifting the trestle body. The tunnel secondary lining construction formwork trolley is simple in structure, reasonable in design, easy and convenient to use and operate, safe and reliable in use process and capable of effectively solving the problems that side wall supports are unreasonable, side walls are prone to retraction deformation, and formwork shifting and upward floating occur in the construction process of traditional trolleys.
Description
technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a formwork trolley for the construction of the second lining of the tunnel based on a rectangular support. Background technique [0002] The tunnel formwork trolley usually refers to the concrete lining trolley, which is a special equipment that must be used in the secondary lining construction during the tunnel construction process, and is used for the construction of the concrete lining on the inner wall of the tunnel. With the rapid development of national infrastructure, the pace of railway construction is making great strides forward. During the construction of the second lining of the single-track railway tunnel, due to the narrow section size of the tunnel, the formwork trolley of the traditional structure is insufficient in the foundation bearing capacity during the stress formation process of the side wall, and the formwork of the side wall often ...
