Abstract

The invention provides a main beam type tunnel segment assembly device and lining method, and solves the problems that the quality is unstable and the construction speed is slow when a tunnel is subjected to secondary lining by a traditional molding method; the main beam type tunnel segment assembly device comprises a tunnel initial lining and a main beam, the main beam is located at the center ofthe interior of the tunnel initial lining, and the main beam is provided with a front support boot group, a rear support boot group, and a lifting crawler wheel from left to right in sequence; the rear portions of the rear support boot group are provided with segment erectors and are hinged to one end of a connecting beam, the other end of the connecting beam is hinged to a slurry injecting trolley, a pea gravel injecting trolley is hinged to the slurry injecting trolley, a main control trolley in hinged to the pea gravel injecting trolley, and the lower portions of the connecting beam and the slurry injecting trolley are provided with segment lifting assemblies.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a main beam type tunnel segment assembly equipment and a lining method. Background technique [0002] At present, in the field of tunnel construction, the construction method of shallow burial and underground excavation is the main method of tunnel construction, and the main construction method for secondary lining of tunnels is the concrete mold construction method. Concrete is poured on site by trolley. This method of construction requires waiting for the concrete to solidify to meet the tunnel strength requirements before demoulding. The construction efficiency is low, and the poured concrete is greatly affected by the environment and the level of construction operators, resulting in unstable quality of the second lining of the tunnel. Problems such as voiding and water seepage are more common. Contents of the invention [0003] The invention proposes a main girder type tunn...
