PROBLEM TO BE SOLVED: To provide a drain pipe-line structure, a construction method of a drain pipe-line and a drain pipe-line construction set capable of preventing the accumulation of waste-water in a flexible pipe and improving workability when the flexible pipe is inserted in a sleeve. SOLUTION: The drain pipe-line structure is so constituted that it is buried in the foundation 2 of a building by passing through the bending sleeve 3A, the flexible pipe 4 is inserted in the bending sleeve 3A to connect an indoor drain pipe 7 communicating with the indoor drainage equipment to an upstream side of the flexible pipe 4, and an outdoor drain pipe 9 communicating with the outdoor drainage equipment is connected to a downstream side of the flexible pipe 4. The bending sleeve 3A is inclined as a whole so as to become low from the upstream side to the downstream side, and the drain pipe-line structure 1 inclined so that the downstream end section of the bending sleeve 3A can become lower, the construction method of the drain pipe-line and the drain pipe-line construction set are provided.
