Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with the examples.
[0012] The present invention mainly includes two major parts of assembling and hoisting of arch plates.
[0013] In the assembly link, the preparation before assembly is carried out first. The arch slab assembly frame is made according to the span, width and sag height of the arch slab after assembly, and the assembly frame is welded with 18-caliber channel steel. In the span direction, two channel steels with a diameter of 18 are used, and the distance between them is 1.5m. Constraint baffles are made at both ends according to the 15mm span of the arch plate, and a sagittal shelf is set in the middle of the span. A lead screw with a diameter of P=38mm and a length of 500mm is set on the top of the vertical frame, and an E18 channel steel movable support is placed on the top of the lead screw. The ground at the lower part of the assembly frame is tamped and leveled wit...
