A conduit repair structure in which solid objects are less likely to accu mulate on a conduit bottom and that, even if solid objects accumulates on th e conduit bottom, facilitates removal of the solid objects. A hollow frame-l ike reinforcement body laid substantially along a cross-sectional shape of a conduit (1) is constructed using a reinforcement member (2) having fitting sections (2p) arranged at predetermined intervals on the inner side of the c onduit (2). Resin inner face members (10) are attached to the inner side of the reinforcement body, and an indurative filling material is placed in the space formed by the inner face members (10) and a conduit inner wall (1a) to form a filling material layer (3). A body section (10c) of each inner face member (10) is formed recessed in its width direction. The recessed shape of the body sections (10c) forms riblets on the bottom of the conduit, and thi s reduces resistance to water flowing in the conduit. Even in conduits, such as a horseshoe-shaped conduit and a rectangular conduit (box culvert), havi ng flat bottoms and in which objects flow at low speed, the structure allows the objects to flow easier.
