Description of the Related Art In recent years, in high-rise houses such as apartments and condominiums, drainage devices A such as toilets and bathtubs on each floor are connected to a collecting pipe C by a horizontal drawing pipe B as shown in a partial longitudinal sectional view in FIG. A drainage system is used in which the upper and lower sleeves of the collecting pipe C are connected to the upstream and downstream ends of the double-layer pipe D.

The upper end of the ventilation path is open to the atmosphere. The collecting pipe C covers the outer peripheral side of the inner collecting pipe C1 with the outer collecting pipe C2, and the inner and outer collecting pipes C1, C2
The inside of the inner collecting pipe C1 is always maintained at the atmospheric pressure through the ventilation path. For this reason, the drainage flowing into the collecting pipe C from the horizontal drawing pipe B smoothly falls into the downstream inner pipe 1 while turning along the inner peripheral wall of the inner collecting pipe C1.
