METHOD FOR TESTING ADHESION STRENGTH OF LOCK BOLT AND GROUT AND TEST PIECE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for testing the adhesion strength of a lock bolt and grout and a test piece thereof obtaining data for adequately and quantitatively evaluating the support effect of the lock bolt. SOLUTION: The method for testing the adhesion strength of the lock bolt 2 and the grout 3 flatly expands the lock bolt 2 and the grout 3 surrounding the lock bolt 2. A grout part 6 expanding on the surface of a lock bolt part 5 expanded applies a shear load to either the lock bolt part 5 or the grout part 6 against the test piece 7 with a laminated shape and therewith a vertical load.
