<p>PROBLEM TO BE SOLVED: To provide an efficient inspection method of a drain pipe of a siphon drainage system after construction.SOLUTION: An inspection method of a siphon drainage system comprising a horizontal pipe 30C for discharging drain water from a water section implement 12C, and a vertical pipe 32C which is connected to a downstream-side end part of the horizontal pipe 30C, and arranged at a lower part in a vertical direction comprises: a first process for connecting a downstream-side end part of another piping (siphon drain pipe 16D) whose upstream-side end part is opened to air and a downstream-side end part of the vertical pipe 32C; a second process for making an inspection fluid flow from an upstream-side end part of the horizontal pipe 30C therein; and a third process for inspecting whether or not there exists fluid leakage at the horizontal pipe 30C, the vertical pipe 32C and the other piping 16D after the inspection fluid reaches an upstream-side end part of the other piping 16D.</p> |
