Arch bridge web arch ring reinforcing structure

Abstract

The invention discloses an arch bridge web arch ring reinforcing structure which comprises a web arch ring body. The two ends of the web arch ring body are both provided with supporting walls. The sides, close to each other, of the two supporting walls are each provided with a plurality of bases. The portions, between the two bases, of the opposite positions of the two supporting walls are both provided with longitudinal arch ribs. At least one cross beam is arranged between the longitudinal arch ribs. Steel pull rods are all arranged between the longitudinal arch ribs and the web arch ring body, between the cross beams and the web arch ring body as well as between the supporting walls and the bases. The longitudinal arch ribs, the cross beams and the bases are all internally provided with steel bar net racks connected with the steel pull rods. By adoption of the structure, the web arch ring body, the bases, the longitudinal arch ribs and the cross beams form a whole and are jointly stressed, the purposes of arch bridge bearing capacity improvement and safe storage are achieved, and compared with traditional structures, light-weight reinforcement is achieved, the numbers of construction sections and masonry are decreased, the construction difficulty and project cost are lowered, and damage to an arch bridge is small; and meanwhile, dead loads generated in the later period are effectively reduced, and the structure has large engineering application value.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a reinforcement structure for the arch ring of an arch bridge. Background technique [0002] With the rapid development of road transportation in our country, the traffic volume is increasing day by day, the speed of vehicles is generally increasing, and the number of heavy vehicles is also increasing day by day. Bridge reinforcement has become an increasingly important project. At present, most of the arch bridges built in China have been built for a long time, and the design load level is relatively low. In addition, after years of operation, the bearing capacity and safety reserve of the bridge can no longer meet the needs of the existing traffic volume, and more and more arch bridges need to be repaired. Reinforcement treatment to improve bridge bearing capacity and safety reserves. [0003] At present, the reinforcement of the arch ring of the arch bridge is mostly reinforc...

AI Technical Summary

Problems solved by technology

[0004] 1. The construction section of the whole set of arches is large, the number of masonry works is large, the damage to the bridge caused by the drilling holes of the original bridge is large, and the construction is difficult;

[0005] 2. The increased dead load of the entire arch is relatively large, and the construction of the entire arch requires a large amount of materials, and the construction cost is high
