It connects and penetrates like a main drainage pipe, and the sewage and miscellaneous water from the living area on each floor is carried through side branch pipes. The drainage system is designed to flow into the drainage standpipe, and the drainage from the side branch pipes on each floor is The receiving part consists of a tubular body with a larger diameter than the drainage standpipe, and a side branch pipe is attached to the circumferential side of the tubular body. A collecting pipe with a protruding joint is interposed in the middle of the drainage standpipe.

【0003】 この一管式排水配管における問題点は、排水が排水立管内を流下するとき、上 階から下階に降下するに従って管内空気圧力の変動が大きく、又、排水騒音が発 生することである。 そこで、従来、上記問題点を解決するための一策として、大径管状の排水集合 管内周面に、その始端部と終端部に向って徐々に幅員を狭くした螺旋状の羽根を 突出状に形成したものが提案されている(特公昭57−18015 号公報参照) 。0003 The problem with this one-pipe drainage piping is that when the wastewater flows down inside the drainage standpipe, the As you descend from floor to floor, the air pressure inside the pipe fluctuates greatly, and drainage noise is generated. It is to live. Therefore, as a way to solve the above problems, conventionally, large-diameter tubular drainage collection was used. A spiral blade with a width that gradually narrows toward the beginning and end is placed on the inner circumferential surface of the pipe. A protruding shape has been proposed (see Japanese Patent Publication No. 18015/1983).
