PURPOSE: A method for splitting bedrock using the pressure of fluid is provided to split bedrock by independently controlling pressure based on the formation state of the bedrock. CONSTITUTION: A method for splitting bedrock using the pressure of fluid is as follows. A free space(170) is formed on the surface of a bedrock(S). Multiple boreholes(100) parallel to each other are formed on each free surface(P) formed in the free space. Expansion units(200) are inserted into the formed boreholes. A cutting line(L) is formed by supplying high-pressure fluid to the expansion units and expanding the boreholes, and the surface of the bedrock is cut along the cutting line. |
