Summary:PROBLEM TO BE SOLVED: To obtain a waterway structure which makes a lining board hardly separable by improving water sealing properties and joining properties without imparting a butt structure to the lining board. SOLUTION: In this structure, a plurality of lining boards 23, which are composed of a thermoplastic resin and provided with a plurality of parallel anchor protrusions 21 with a widened leading end, are connected to a surface on the side of a wall-to-be-repaired in a downflow direction, while a gap 25 is formed in such a manner that the anchor protrusions 21 are directed to the wall-to-be-repaired 1a of a waterway 1; and concrete 27, which is infilled between the wall 1a and the lining board 23, is solidified. In a connecting section between the lining boards 23 connected together in the downflow direction, the upstream-side lining board is arranged on an upper layer; the downstream-side lining board is arranged on a lower layer; and the finishing inner surface of the lower lining board is joined to the surface, on the side of the wall-to-be-repaired from which the anchor protrusions 21 of the upper lining board are removed.
