The invention discloses a seamlessly-connected flexible rail. The seamlessly-connected flexible rail comprises a first guide rail and a second guide rail which are spliced in the length direction, thefirst guide rail comprises a first guiding face, and the second guide rail comprises a second guiding face; and the flexible rail comprises a mounting face and a sliding face which are arranged oppositely and extend in the same direction, the first guiding face and the second guiding face are sequentially covered with the mounting face in the length direction, the sliding face is used for supporting routing inspection equipment, and the routing inspection equipment is slidably arranged on the sliding face in the length direction of the sliding face. According to the seamlessly-connected flexible rail, the jolt and vibration frequency of the routing inspection equipment during transition moving between adjacent subrails is lowered, the monitoring effect of the routing inspection equipmentis improved, the problem of rail sticking is avoided, the frequency that the routing inspection equipment impacts on a routing inspection rail is decreased, the service life of the routing inspectionrail is prolonged, and the using cost of the routing inspection rail is lowered.
