<p>PROBLEM TO BE SOLVED: To provide a joint structure of a pipe body such as a box calvert and a shield tunnel to be embedded in the ground submerged and capable of providing a water stop function while allowing relative displacement in each direction between adjacent pipe bodies. SOLUTION: This flexible joint structure constituted by connecting adjacent cylindrical rigid members 5 by a beltlike elastic member 2 is constituted in such a way that water-tight mounting parts 3 with the cylindrical rigid members 5 are provided at both ends of the beltlike elastic member 2, a distance between both water-tight mounting parts of the beltlike elastic member 2 is longer than a straight line distance L between mounting parts of adjacent cylindrical rigid members, and the shape formed by mounting parts 10 of both of the cylindrical rigid members 5 mutually is a v shape when viewed in a cross section.</p> |
