The invention discloses an arch foot maintaining device and a maintenance method for achieving multi-degree-of-freedom displacement of an arch foot. The device includes a plurality of supporting structures, and the supporting structure includes a base (1), two base supporting seats (7), a hydraulic jack (2), a roller (3), and a roller supporting seat (4). The base (1) is a cuboid with equal length and width, a through hole running through side surfaces of the base (1) is provided on the base (1). A vertical guide groove is provided on each of the two base supporting seats (7). The roller supporting seat (4) is U-shaped and located between the two base supporting seats (7), and the roller (3) is rotatably supported in the roller supporting seat (4). Two ends of a central axis (14) of the roller (3) are respectively located in the two guide grooves, the hydraulic jack (2) is disposed within the base (1), and a top of the hydraulic jack (2) abuts against a bottom of the roller supporting seat (4). A plurality of supporting structures are freely combined to form an arch foot maintaining device, and an arch foot is sectioned and lifting/lowering of each roller (3) is controlled to achieve translation and rotation of the arch foot. The invention is simple in structure, flexible, convenient in operation, and highly adaptable, and therefore may be widely applied in arch foot maintenance and strengthening.
