DRAIN PIPE CLEANING METHOD
To provide a drain pipe cleaning method capable of reliably preventing backflow of muddy water due to cleaning of a drain pipe particularly for an individual house on a lower floor.SOLUTION: A drain pipe cleaning method comprises: a first step of inserting a vertical pipe cleaning nozzle 5 attached to a water hose 6 from the top of a vertical pipe 2 into the lower bottom of the vertical pipe without jetting high-pressure water, a second step in which, simultaneously with or before or after the execution of the first step, a horizontal pipe cleaning nozzle 7 attached to a water hose 8 from the downstream side of a horizontal pipe 3 is advanced toward the lower bottom of the vertical pipe while jetting high-pressure water, a third step of cleaning the inside of the vertical pipe by pulling up the vertical pipe cleaning nozzle 5 located at the lower bottom of the vertical pipe while jetting high-pressure water inside the vertical pipe, and a fourth step of moving the horizontal pipe cleaning nozzle 7, during the execution of the third step, from the lower bottom of the vertical pipe toward the downstream side of the horizontal pipe while jetting high-pressure water from the horizontal pipe cleaning nozzle 7.SELECTED DRAWING: Figure 1
【課題】特に下層階における個別の宅内に対して、排水管の洗浄による泥水が逆流するのを確実に防止させることができる排水管の洗浄工法を提供すること。【解決手段】立管２の上部から、送水ホース６に取り付けられた立管洗浄用ノズル５を、高圧水の無噴射の状態で立管の下底部に挿入する第１工程と、第１工程の実行と同時に又は前後して、横引き管３の下流側から送水ホース８に取り付けられた横引き管洗浄用ノズル７を、高圧水を噴射させながら、立管の下底部に向かって進行させる第２工程と、立管の下底部に位置させた立管洗浄用ノズル５から高圧水を噴射させながら、立管内で引上げることで、立管内を洗浄する第３工程と、第３工程の実行中において、横引き管洗浄ノズル７から高圧水を噴射させながら、横引き管洗浄ノズル７を、立管の下底部から横引き管の下流側に向かって移動させる第４工程が実施される。【選択図】図１
