description The present invention relates to a single-hinge 10000-ton horizontal swivel construction method of a steel pipe arch bridge. The steel pipe arch is separated into two parts which are respectively assembled and welded to form a half-span arch on the assembling supports of both banks, one end of the half arch of the steel pipe arch is fixed on a horizontal hinged support, a balance measure is applied to separate steel pipes from the supports, bearings form a swivel on the horizontal hinged support, and finally the swivel is driven to horizontally rotate in order to realize the closure of the steel pipe arches of both banks. The present invention relates to a single-hinge 10000-ton horizontal swivel construction method of the long-span steel pipe arch bridges of roads and railways, and the weight of the related single swivel is over 10000 ton. The present invention is particularly applied to occasions in which a canyon needs to be spanned or the clearance under a bridge is not occupied, and has the advantages of
