Automatic hydraulic inverted arch trestle trolley and construction method thereof

The invention discloses an automatic hydraulic inverted arch trestle trolley which comprises a trestle system and inverted arch mold frame systems, wherein a trestle bogie is arranged on the trestle system, and is connected with the inverted arch mold frame systems; each inverted arch mold frame system comprises an inverted arch mold longitudinal beam and an arc inverted arch template group; each arc inverted arch template group comprises a fixed inverted arch template and a movable inverted arch template; a stretching mechanism is arranged between each movable inverted arch template and the corresponding inverted arch mold longitudinal beam; lifting supporting legs are arranged at the bottom of an inverted arch template transversal beam; an inverted arch travelling mechanism capable of stretching up and down is arranged at the bottom of the tail end of each inverted arch mold longitudinal beam; transversal moving mechanisms are arranged at the two ends of the trestle system in the longitudinal direction; trestle travelling wheels are arranged at the tail ends of the trestle system. A trolley construction method comprises the following steps: moving trestle in position, excavating inverted arch, binding steel bars, demolding the inverted arches, moving molds in position, and molding and pouring. According to the invention, quick inverted arch operation conduction of a whole tunnel on the same fracture surface can be realized, assembly and disassembly of the templates are avoided, the labor intensity of workers is greatly reduced, and the construction efficiency and the construction quality are improved.
