Arching method for stiff skeleton concrete arch bridge
The invention belongs to the technical field of bridge engineering, and particularly relates to an arching method for a stiff skeleton concrete arch bridge. The arching method sequentially includes the following steps that A, segments of an arch ring stiff skeleton are spliced till the segments are folded; B, concrete in steel pipes of the arch ring stiff skeleton is pressed and poured; C, secondary fastening cables are tensioned; D, outer wrapped concrete of the arch ring stiff skeleton is poured; and E, the secondary fastening cables are detached. According to the arching method, due to tensioning of the secondary fastening cables, in the outer wrapping pouring process, no other supporting components need to be arranged for supporting the arch ring stiff skeleton; firstly, the construction cost is reduced, and the construction difficulty is lowered; meanwhile, due to the fact that the fastening cables are used for tensioning the arch ring stiff skeleton, the occupied space is smaller than that of other supporting manners during connection of the fastening cables and an arch ring; and blocking in the following concrete pouring process is reduced, and following concrete pouring construction is further facilitated.
