STRUCTURE OF PIPELINES AND UPDATE METHOD FOR PIPELINES
To provide a pipeline structure and an update method for the pipelines that reduce material cost and labor hours for construction as compared to conventional two-pipeline ventilation systems, and is applicable to mid-to-high-rise buildings.SOLUTION: A single system drainage channel is constructed by a combination of a drainage vertical pipe 2 and a lateral drainage pipe 3 connected to a main drainage pipe 8, a bend part 4 is provided between the drainage vertical pipe 2 and the lateral drainage pipe 3, a special drainage joint 5, which allows drainage while forming a ventilation space inside, is provided at a confluence part where drainage merges midway along the drainage vertical pipe 2, a first vent pipe is connected below the special drainage joint 5, which is located below the drainage of a middle floor of a building, a second vent pipe 6b is connected below the special drainage joint 5, through which the drainage of a lowest floor of the building passes, a third vent pipe 6c is connected below the bending part 4, at least in each drainage channel, the lateral drainage pipe 3 has an elbow EL in front of a connection point to the main drainage pipe 8, and a bypass vent pipe 6g is located at an upstream side and a downstream side of the elbow EL.SELECTED DRAWING: Figure 2
【課題】従来の二管路通気方式の管路に比べて資材コストや施工工数を減らし、中高層の建物に適用可能とする。【解決手段】排水竪管２と、主排水管８に接続される横行排水管３の組み合わせにより、一系統の排水路が構成されており、排水竪管２と横行排水管３との間に曲げ部４を有し、排水竪管２の途中で排水が合流する部分には、排水を通しつつ内部に通気空間を形成できる特殊排水継手５が設けられており、各系統の排水路にて少なくとも、建物中間階の排水が通されるうちで下側に位置する特殊排水継手５の下方に第１通気管が接続され、建物最下階の排水が通される特殊排水継手５の下方に第２通気管６ｂが接続され、曲げ部４の下方に第３通気管６ｃが接続されており、横行排水管３は、主排水管８への接続箇所の手前にエルボＥＬを有しており、エルボＥＬの上流側と下流側に接続されるバイパス通気管６ｇが配置されている。【選択図】図２
