HORIZONTAL DRAIN PIPE
To provide a horizontal drain pipe that can solve the following problems, wherein in the conventional horizontal drain pipe, at the elbow pipe section, there was a risk of generating grooves due to protrusions caused by burrs during the cutting of the straight pipe, or due to the cut surface of the straight pipe not being perpendicular and flat, as a result, waste water or sewage was more likely to adhere to the protrusions or grooves inside the horizontal drain pipe, or microorganisms were more likely to proliferate, leading to the occurrence of so-called slime, and causing a problem that periodic cleaning of the drain pipe became necessary.SOLUTION: The horizontal piping 1 has one or more bent portions bent with a bending radius of 8 to 12 times the nominal diameter of the pipe, and is formed to connect from a fixture drain port side connection hole 9 of a drainage fixture requiring drainage to a riser side connection hole 8 of a riser pipe with a single thermoplastic resin pipe.SELECTED DRAWING: Figure 2
【課題】従来の横引き排水管のエルボ管の部分については、直管の切断時におけるバリによる突起や、直管の切断面が直角かつ平面でないことにより溝が生じるおそれがある。このため、横引き排水管の内部の突起や溝があることにより、前述の雑排水や汚水が付着し易くなり、微生物の繁殖がし易くなり、所謂ヌメリが発生することになった。そのため、定期的に、排水管の掃除が必要になるという問題があった。【解決手段】横引き配管１は、管の呼び径の８倍から１２倍の曲げ半径で曲げられた曲げ箇所を１か所以上有し、排水が必要な排水付器具の器具排水口側接続孔９から、立て管の立て管側接続孔８までを、１本の熱可塑性樹脂管で接続するように形成されている。【選択図】図２
