A manhole repair structure is provided to reduce the time for curing a filler placed in the space around a manhole, thereby shortening the manhole repair time. A manhole repair structure comprises an anchor part(110), a height adjusting part(120), a first filler(130), and a second filler(140). The anchor part comprises anchors(111) which are inserted in anchor holes formed on a concrete structure, and anchor bolts(112) which are fitted in the anchors. The anchor part is fixed to the upper side of the concrete structure exposed through the space formed by cutting out a road pavement surface. The height adjusting part comprises a support(121) with a connection hole in which the anchor bolt is inserted, a reinforcing support(123) including a reinforcing plate bent in an arc shape, and a height-adjusting male screw part(124) which includes a contact member making in contact with the upper surface of the concrete structure and is screwed to a female screw part(125). The height adjusting part raises a manhole frame so that the manhole frame is flush with the road pavement surface. The first filler is ultra rapid-hardening cement filled and cured between the upper surface of the concrete structure and the manhole flange. The second filler is ascon of 120~160‹C filled between the upper surface of the first filler to the road pavement surface. |
