Ladder used for communication inspection wells
The invention discloses a ladder used for communication inspection wells. The ladder comprises two support bars and foot rests; the plurality of foot rests are arranged between the support bars at intervals; the foot rests are of arc-shaped structures, and arc curvature of the foot rests matches that of the inside walls of the communication inspection wells. According to the ladder, structure optimization is adopted, so that reasonable using of the special space of inspection wells is realized, more larger action space is provided when servicemen come in and go out of the inspection wells using the ladder, and uncomfortableness caused by collision of knees with the ladder is avoided.
