<p>PROBLEM TO BE SOLVED: To provide a drain confluence pipe in which a siphon phenomenon is not generated on the branch-pipe section side even when drainage is conducted in a main pipe section in the drain confluence pipe. SOLUTION: In the drain confluence pipe (1) composed of the main pipe section (2) in which drain flows and a branch pipe section (3) being installed so as to be projected in the side-face direction of the main pipe section (2) and making drain flow into the main pipe section (2) side, a drain inflow mechanism making a part of drain from the main pipe section (2) flow into the branch pipe section (3) side is mounted at the place of a connection with the branch pipe section (3) of the main pipe section (2). In the drain confluence pipe (1) consisting of the main pipe section (2) in which drain flows and the branch pipe section (3) being secured so as to be projected in the side-face direction of the main pipe section (2) and making drain flow into the main pipe section (2) side, the main pipe section (2) is deviated at the place of the connection with the branch pipe section (3) of the main pipe section (2), and the drain inflow mechanism making a part of drain from the main pipe section (2) flow into the branch pipe section (3) side is formed at the place of deviation.</p> |
