PROBLEM TO BE SOLVED: To provide a cleaning method and a cleaning system of a siphon pipe conduit using sherbet-like fluid.SOLUTION: The cleaning method of a siphon pipe conduit 80 is provided for cleaning the siphon pipe conduit 80 for communicating and connecting an upstream side shaft 74 connected to an upstream side pipe conduit 72 and a downstream side shaft 78 connected to a downstream side pipe conduit 76 at a lower position than both pipe conduits 72 and 76, in a state of water staying in the upstream side shaft 74, the downstream side shaft 78 and the siphon pipe conduit 80. The cleaning method of the siphon pipe conduit includes (A) a sealed area forming process of forming a sealed area 12 in a lower area than the pipe conduit 76 connected to the shaft 78 of one shaft 78, and (B) a fluid flow sending process of sending a flow of fluid 20 toward the other shaft 74 in the siphon pipe conduit 80 by continuously executing the pressurization introduction by filling the introduced fluid 20 in a connection part 82 between the siphon pipe conduit 80 and the one shaft 78 by pressurization-introducing the sherbet-like fluid into the sealed area 12. |
