<P>PROBLEM TO BE SOLVED: To provide a joint for a horizontal main drainage pipe, capable of preventing revolution or turbulence of drainage water in proximity upstream of the leg joint. <P>SOLUTION: A joint 28 for a horizontal main drainage pipe has a horizontally extending tubular joint body 31 which allows air and drainage water to pass therethrough and socket parts 32 which are arranged at openings of the joint body 31 and can be connected to a midpoint of the horizontal main drainage pipe. The joint body 31 is internally provided with an air/water flow dividing part 37 which prevents the inflow drainage water from vertically revolving or suppresses the turbulence of the drainage water such that an air current portion and a drainage water current portion are vertically separated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
