The present invention relates to a flexible joint to be inserted between culvert sections. In a culvert joint which consists of anchor members attached to the opposing culvert sections, a flexible member extending between said anchor members and a large number of strengthening members arranged in parallel at the internal and external positions of said flexible member, said strengthening members being classified into one with projections and one with holes to regulate the distance between them; the projections of said member with projections fit into the holes of said member with holes to overlap each other, thereby regulating the distance between them to follow an expansion and contraction or an uneven subsidence of the culvert and therefore, bearing earth pressure sufficiently. |
