PROBLEM TO BE SOLVED: To provide a connection structure between flexible water cutoff members for divided flexible precast concrete members, which dispenses with special-shaped joint portion of a flexible water cutoff rubber between unit blocks formed by transversely dividing the flexible water cutoff rubber, facilitates connection thereof to each other, and contributes to easy execution of work in a short time, and to provide a connection method for the flexible water cutoff members. SOLUTION: A two-divided box culvert 10 is formed by vertically combining two caissons, i.e. the upper caisson 10U and the lower caisson 10L, with each other, and the flexible water cutoff rubber 13U for the upper caisson 10U is connected to the flexible water cutoff rubber 13L for the lower caisson 10L via a core member 21 inserted into a cylinder portion 13A of the flexible water cutoff rubber 13, and a joint rubber plate 22 interposed between both abutting end faces of the flexible water cutoff rubbers.
