Abstract

The invention discloses a beam bridge system reinforcing device of a boom arch bridge, which comprises a newly added longitudinal beam arranged along the longitudinal bridge direction of the boom archbridge, positioned between two arch feet of the boom arch bridge, and connected with a cross beam or a stiffening beam of the boom arch bridge through a first connecting piece; a newly-added pier stud located between two arch feet of the boom arch bridge, and connected with the newly-added longitudinal beam through a second connecting piece so as to support the newly-added longitudinal beam. Theinvention further discloses a girder bridge system reinforcing method of the boom arch bridge. The arch ring stress of the boom arch bridge can be replaced, meanwhile, the effect of newly adding archbridge tie bars can be achieved, the traffic influence in the construction process is reduced, the boom arch bridge safety reserve is improved, boom stress is reduced, the service life of boom is prolonged, the possibility of accidents caused by failure of a single boom is eradicated, the bridge maintenance cost is reduced, and universality is high.

Description

technical field [0001] The invention relates to the technical field of bridge construction. More specifically, the present invention relates to a reinforcing device and method for a girder bridge system of a hanger arch bridge. Background technique [0002] Suspension arch bridges are widely used because of their good economy and strong spanning ability. After the large-scale construction period in the last century, most suspension arch bridges need to be repaired and strengthened. However, due to the design concept, design method and construction method of some hanger arch bridges, there are hidden dangers in the girder bridge system of the existing hanger arch bridges. [0003] At present, the existing reinforcement methods of hanger arch bridges mainly include: adding longitudinal beams, replacing hangers, etc. Adding a new longitudinal beam will increase the dead load, resulting in insufficient safety reserve of the suspender, and replacing the suspender cannot complet...
