Rapid masonry-lining roadway forming device

Abstract

The invention discloses a rapid masonry-lining roadway forming device. The rapid masonry-lining roadway forming device comprises a sliding module; the sliding module comprises a top arc plate, upper arch plates and side arc plates; the top arc plate is positioned between the outer surfaces of the top ends of the two upper arch plates; the side arc plates are positioned at the outer surfaces of thelower ends of the upper arch plates; upper cross beams are fixedly mounted between the inner side surfaces of the top arc plate; an upper longitudinal beam is fixedly arranged between the two upper cross beams; a jack is arranged on the outer surface of the lower end of the upper longitudinal beam; middle longitudinal beams are fixedly mounted on the outer surface of the lower end of the jack; amiddle cross beam is fixedly mounted between the two middle longitudinal beams; and a lower cross beam and a lower longitudinal beam are arranged below the middle longitudinal beam. The problems thatthe lining construction speed of a traditional roadway is low, channel steel templates are repeatedly disassembled and assembled and are low in repeated utilization rate, a construction method is complex and the surface smoothness is poor are solved, the rapid masonry-lining roadway forming device is convenient and quick and has high mechanization degree, and the lining pouring efficiency and quality of the roadway can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of roadway forming devices, in particular to a fast roadway forming device for masonry roadways. Background technique [0002] The coal-bearing strata of the Jurassic Yan'an Formation in Northwest China are dominated by water-rich soft rocks, the hydrogeological conditions are relatively complex, the strata are poorly cemented, soft and brittle, easily weathered and muddy, and the surrounding rock itself has low bearing capacity. The amount of deformation after anchoring, net spraying support is very large. If the permanent support of reinforced masonry is not used, the roadway after deformation cannot meet the needs of safe production. Therefore, some coal mines use reinforced masonry for the whole rock development roadway with a long service life. permanent support. After the permanent support of reinforced masonry, the roadway deformation is effectively controlled. [0003] In the process of realizing t...
