Abstract

The invention discloses a replacing device for a concrete tied arch bridge flexible suspension rod. The replacing device comprises a suspension rod replacement tensioning device, a suspension rod replacement executing device and a suspension rod replacement monitoring device; the suspension rod replacement tensioning device comprises a cross-core hydraulic jack, an oil conveying pipeline, an oil hydraulic pump and an oil valve, the cross-core hydraulic jack is connected with the oil valve through the oil conveying pipeline, and the oil valve is communicated with the oil hydraulic pump. The invention further provides a using method of the replacing device for the concrete tied arch bridge flexible suspension rod. The replacing device is suitable for replacing suspension rods different in distance and length; two replacing devices are independently arranged at the two sides of the suspension rod and are easy to operate and high in controllability and achieves dual safety guarantee. The replacement process is low in cost, and occupied bridge floor space is small. Concrete leveling blocks are cast on an arch rib in a on-site mode, replacement operation is convenient, and vertical displacement of the bridge floor and the arch rib at all suspension rods can be controlled accurately.

Description

technical field [0001] The invention relates to a flexible suspender replacement device for a concrete tie-bar arch bridge and a method for using it, and belongs to the technical field of bridge engineering reinforcement and maintenance. Background technique [0002] Concrete tied arch bridges have the advantages of reasonable structure, clear force, and high vertical rigidity. This type of bridge not only has advanced technical and economic indicators, but also has low requirements on geological conditions, so it is widely used. The suspender is one of the main load-bearing members of the tied arch bridge, which transmits the bridge deck load to the arch rib. In the long-term use process, various diseases will appear in the suspenders of concrete tie-bar arch bridges, mainly including: first, sheath damage; second, suspender steel wire corrosion; third, anchorage corrosion. Therefore, when the suspenders reach their service life, these old suspenders will be replaced in t...
