VALVE DEVICE USED WHEN RENEWING DRAINAGE HORIZONTAL PIPE AND RENEWAL CONSTRUCTION METHOD OF DRAINAGE HORIZONTAL PIPE COMPRISING RENEWING DRAINAGE HORIZONTAL PIPE
To provide a valve device used when renewing a drainage horizontal pipe and a renewal construction method of the drainage horizontal pipe, that prevent damage to downstream residences even in an event of accidental water discharge.SOLUTION: A valve device 100 for dividing a drainage horizontal pipe arranged to extend in a lateral direction into an upstream drainage horizontal pipe 210 arranged upstream and a downstream drainage horizontal pipe arranged downstream, and for renewing the downstream drainage horizontal pipe to a new downstream drainage horizontal pipe while storing drainage flowing into the upstream drainage horizontal pipe comprises: a valve part 50 that has a first joint 10 attached to a downstream end part of the upstream drainage horizontal pipe, an openable/closable valve 20 located downstream of the first joint, and a second joint 30 for attaching the downstream drainage horizontal pipe to an upstream end part of the new downstream drainage horizontal pipe; a hose part 80 that is detachably attached to the second joint in the valve part; and a tank part 90 that is attached to the hose part and stores drainage flowing into the upstream drainage horizontal pipe.SELECTED DRAWING: Figure 1
【課題】うっかり排水をしたとしても下流の住居内に被害が及ばない、排水横引き管を更新するときに使用するバルブ装置と、排水横引き管更新工法を提供する。【解決手段】横方向に延在するように配置された排水横引き管を、上流に配置された上流排水横引き管２１０と下流に配置された下流排水横引き管と、にそれぞれ分割し、前記上流排水横引き管に流入した排水を貯留しつつ、前記下流排水横引き管を新規な下流排水横引き管に更新するために、前記上流排水横引き管の下流端部に取り付ける第１継手１０と、第１継手の下流に配置する開閉可能なバルブ２０と、新規な下流排水横引き管の上流端部に取り付けるための第２継手３０と、を具備するバルブ部５０と、バルブ部における第２継手と取り外し可能に取り付けるホース部８０と、ホース部に取り付けられ、上流排水横引き管に流入した排水を貯留するタンク部９０と、を有するバルブ装置１００である。【選択図】図１
