Inland water pressure compressed strength ON test method null of closed-end cylindrical

摘要

PROBLEM TO BE SOLVED: To provide an internal water-pressure pressurizing strength test method wherein a destructive stress at an arbitrary part of a closed-end cylinder body at will. ;SOLUTION: With rubber tube 15 having a shape complementary to the inside part of a closed-end cylinder body 1 set inside the closed-end cylinder body 1, a fluid is ingtroduced from an opening part of the closed-end cylinder body 1 to the rubber tube 15, and the fluid is applied with a pressure, so that a destructive stress of the closed-end cylinder body 1 is examined. At a part other than where a destructive stress of the closed-end cylinder body 1 is measured, a sleeve 5 which is not deformed under a water pressure is placed between the rubber tube 15 and the inside wall of the closed-end cylinder body 1.;COPYRIGHT: (C)1998,JPO
