Construction system and construction method for ribbon deformation height steel box decorative multi-arch landscape bridge

Abstract

The invention provides a construction system and a construction method for a ribbon deformation height steel box decorative multi-arch landscape bridge. A ribbon ground pre-assembled shaped jig frame,an arch rib installation adjustable temporary oblique supporting system, a side span bent cap consolidation arch foot installation auxiliary support system, a middle span bent cap consolidation archfoot installation auxiliary support system and a sidewalk longitudinal beam arch rib suspender installation system are arranged. The ribbon ground pre-assembled shaped jig frame provided with the jacking devices, the threaded positioning ribs and the universal wheels is adopted for assembling the steel box, the jig frame is convenient to move and install, the assembling effect is good, and the construction progress is accelerated; by arranging the arch rib installation adjustable temporary inclined supports and the auxiliary support for installing the arch feet of the consolidation of the sidespan capping beam and the middle span capping beam, the stability of the installation process is good, and the safety of steel box bridge body construction is guaranteed; the operation platform is erected on the lower portion of the sidewalk for suspender construction, the sleeve is pre-buried, a suspender installation system is formed, the suspender installation speed is increased, and accuracyis good.
