Split integrated underground passage steel mold plate trolley and construction method thereof

The invention discloses a slit integrated underground passage steel mold plate trolley and a construction method thereof, relates to the technical field of underground passage building concrete construction, and aims at the problems that the existing underground passage construction equipment is large in occupied area, the construction method is long in curing time, and continuous pouring construction cannot be realized. The steel mold plate trolley comprises at least three frame-type mold plate supporting devices which are connected integrally through detachable box-shaped cross beams, and at least two groups of posterior disassembly top mold plate supporting devices; a traveling mechanism at the lower part of the steel mold plate trolley can drive the frame-type mold plate supporting devices to move along longitudinal tracks; the two frame-type mold plate supporting devices positioned on the outer side can move in the horizontal direction under the operational control of a horizontal hydraulic oil cylinder group; each frame-type mold plate supporting device can lift in the vertical direction under the operational control of a vertical hydraulic oil cylinder group which is mounted on the corresponding frame-type mold plate supporting device; the at least two groups of posterior disassembly top mold plate supporting devices are respectively connected between the two adjacent frame-type mold plate supporting devices by bolts; universal wheels used for travelling are mounted at the bottom parts of the posterior disassembly top mold plate supporting devices.
