PROBLEM TO BE SOLVED: To provide a drain pipe closure detecting system capable of precisely detecting a residual or an accumulated state of a solid or the like in a drain pipe and a drain pipe closure automatic prevention system making use of the drain pipe closure detecting system even if the solid or the like is mixed in waste water. ;SOLUTION: The drain pipe closure detecting system includes a blast means 20 for sending an air to the inside of the drain pipe 2, an air pressure detecting means 21 for detecting an air pressure produced by the blast means and an operation controlling means 15 for analyzing/recording variations in a value detected by the air pressure detecting means, and it detects the closure by the residual or the accumulation of the solid or the like in the drain pipe by detecting the variations in the air pressure by the operation controlling means.;COPYRIGHT: (C)2003,JPO
