<p>PROBLEM TO BE SOLVED: To efficiently crush an object to be crushed such as a base rock, a concrete structure, and a rock.SOLUTION: A crushing method includes: a first step of forming a drilled hole 2 on an object 1 to be crushed such as a base rock, a concrete structure, and a rock; a second step of inserting a crushing force generation member 3, a wedge member 4, and movable members 5, 5 into the drilled hole 2 in this order, arranging the wedge member 4 movably in the formation direction of the drilled hole 2 at a position close to the crushing force generation member 3, and arranging the movable members 5, 5 slidably on an inclined surface formed on the wedge member 4; and a third step of pressing the movable members 5, 5 against an inner wall surface of the drilled hole 2 by generating crushing force in the drilled hole 2 by the crushing force generation member 3 and moving the wedge member 4 to an opening side of the drilled hole 2 with the crushing force, so as to crush the object 1 to be crushed.</p> |
