NONDESTRUCTIVE TESTING METHOD FOR UNDERWATER CONCRETE STRUCTURE USING REBOUND HAMMER

摘要: PROBLEM TO BE SOLVED: To solve a problem wherein measuring function is not operated sufficiently to allow an accurate test, because water intrudes into inside of rebound hammer when used under water, as the execution test taken consideration in conventional method. SOLUTION: This nondestructive testing method for underwater concrete structure uses built pressure-resisting vessel preventing intrusion and influence pressure, has performance having all functions same those on land.
