PROBLEM TO BE SOLVED: To improve working environment during inspection by reducing obstruction of downflow in a main pipe and suppressing splashing of sewage, in making falling fluid from a perpendicular vertical pipe immediately above the main pipe flow out into the main pipe in sewerage.SOLUTION: A bridge pipe 10 of an outflow pipe device 3 is constructed in an upper portion than the intermediate portion in the height direction inside a main pipe 1, so as to cross a vertical pipe 2. A connecting portion for a vertical pipe 20 is provided on an upper face portion 11 of the bridge pipe 10, and is connected to a lower end portion of the vertical pipe 2. An outflow pipe 30 is extended downwardly from an end portion of the bridge pipe 10 along an inner periphery of the main pipe 1. An outflow port 35 is formed in a lower end portion of the outflow pipe 30.SELECTED DRAWING: Figure 1
【課題】下水道における幹管の直上の垂直な縦管からの落下流体を幹管へ流出させる際、幹管における流下阻害を低減するとともに、下水の飛沫化を抑制して、点検時の作業環境を改善する。【解決手段】幹管１の内部の高さ方向の中間部より上側の部分に、流出管装置３の架設管１０を、縦管２と交差するように架設する。架設管１０の上面部１１に縦管接合部２０を設け、縦管２の下端部と接続する。架設管１０の端部から流出管３０を幹管１の内周に沿って下方へ延ばす。流出管３０の下端部に流出口３５を形成する。【選択図】図１
