摘要： PROBLEM TO BE SOLVED: To shorten time required for removing operation of deposits and graphitized corroded part on cast iron pipe outer surfaces.SOLUTION: An excavation pit 7 is dug toward a ductile cast iron pipe 25 buried underground, a blast agent and high pressure water supplied from a high pressure pump are jetted together from a nozzle gun 4, toward the deposits which are stuck to the cast iron pipe outer surfaces 26 of the ductile cast iron pipe 25 exposed in the excavation pit 7 and toward the graphitized corroded part in which iron of the cast iron pipe outer surfaces 26 is corroded and a graphite layer remains on the cast iron pipe outer surfaces 26, and thus, the deposits and the graphitized corroded part are removed from the cast iron pipe outer surfaces 26. Consequently, only with a series of operations of jetting the blast agent and the high pressure water together from the nozzle gun 4, both the deposits and the graphitized corroded part can be scraped off from the cast iron pipe outer surfaces 26 with the blast agent jetted from the nozzle gun 4, and time required for the removing operation of the deposits and the graphitized corroded part on the cast iron pipe outer surfaces 26 can be shortened.

摘要： PROBLEM TO BE SOLVED: To objectively grasp the state produced of damage or peeling of coating on the inner peripheral surface of piping, without requiring an imaging means that has a complex structure or a complex work.
SOLUTION: The observed image of the inspection region W, set to the inner peripheral surface of the piping P, is acquired from the outside in the piping axis direction of the inspection region W and the feature part K, where a damage or the peeling of coating is produced, in the observed image is extracted to calculate the area ratio J of the feature part K occupied in the inspection region W, on the basis of the area of the feature part K on the observed image. If the observed image is acquired from the outside, in the piping axis direction of the inspection region W, the observed image of the inspection region W as a whole can be acquired, without revolving the imaging means 2, or the like, and the imaging means 2 having the complicated structure or the complicated work is not required. Furthermore, if the area ratio J of the feature part K, occupied in the inspection region W, can be calculated on the basis of the area of the feature part K on the acquired observed image, the state of the damages or peelings of coating produced on the inner peripheral surface of the piping P can be grasped objectively.

摘要： PROBLEM TO BE SOLVED: To provide a centering tool for a pressing ring capable of securing a watertight action of a rubber ring by directly and uniformly pressing the rubber ring with the pressing ring while maintaining the condition that the pressing ring is centered.SOLUTION: The centering tool 1 for the pressing ring is formed by welding a centering section 4 to be inserted between an inserting side tube 2 and the pressing ring 3, and a fixing section 5 having a magnet 6 and fixed to the pressing ring 3 at an approximately cross-sectioned L shape. The inserting side tube 2 wherein the pressing ring 3 and the rubber ring 8 are passed through in advance is inserted into a receiving side tube 9, and the centering section 4 of the centering tool 1 is inserted into the top of an outer peripheral surface which is a gap between the outer peripheral surface of the inserting side tube 2 and an inner peripheral surface of the pressing ring 3. Further, the magnet 6 arranged on the fixing section 5 is fixed by making the magnet stick to an inserting side end face of the pressing ring 3. Thus, the pressing ring 3 can maintain its centered state since the centering tool 1 can be hardly slipped off during pushing of the pressing ring 3 by making the centering tool 1 fix with the pressing ring 3, and the watertight action of the rubber ring 8 can be secured for a long period since the rubber ring 8 is directly pushed with the pressing ring 3.
