Abstract

The invention discloses an arch foot maintenance device and a maintenance method for realizing arch foot multi-degree-of-freedom displacement. The device includes a plurality of support structures, the support structure comprises a base, two base supports, a hydraulic jack, a roller and a roller support mount, the base is a cuboid of equal length and width, the base is provided with a through holethrough the side of the base, the two base support seats are provided with vertical guide grooves, the roller support seat is U-shaped and located between the two base support seats, the roller is rotatably supported in the roller support seat, the two ends of the roller central shaft are respectively located in the two guide grooves, and the hydraulic jack is arranged in the base and abuts on the bottom of the roller support seat. The invention freely combines a plurality of supporting structures to form an arch foot maintenance device, and realizes the translation and rotation of the arch foot by cutting the arch foot and controlling the lifting and lowering of each roller. The invention has the advantages of simple structure, flexible and changeable, convenient operation and strong adaptability, and can be popularized and applied in arch foot maintenance and reinforcement.

Description

technical field [0001] The invention relates to the technical field of arch foot maintenance of arch bridges, in particular to an arch foot maintenance device and a maintenance method for realizing multi-degree-of-freedom displacement of arch feet. Background technique [0002] Arch bridges have a long history of construction and are beautiful in appearance. They are one of the important bridge types in the field of bridges today. Due to the frequent occurrence of geological disasters, arch bridges have different degrees of bridge diseases due to foundation settlement and deformation. For bridges with diseases, if they continue to operate without maintenance, there will be great safety hazards, and premature demolition and reconstruction will cause huge economic losses. Therefore, it is of great practical significance to repair and strengthen arch bridges with arch foot displacement. Common bridge maintenance and reinforcement methods in previous projects mainly include ex...
