Abstract
PURPOSE: To reduce the number of days required for construction by jetting an abrasive-mixed, highly compressed water from a cutting fluid jetting nozzle provided at a contiguous position to a cutter heater outer periphery, and thereby cutting obstacles. CONSTITUTION: A cutting fluid jetting nozzle 3 is provided at a contiguous position to the cutter head 2 outer periphery of a shield machine 1, and abrasive- mixed, highly compressed water having an abrasive blended in highly compressed water is jetted toward obstacles 4 from a nozzle 3. When obstacles 4 are cut, the nozzle 3 is moved in the crossing direction of the obstacles 4, and the obstacles 4 are cut by jetting abrasive-mixed, highly compressed water from the nozzle 3. Consequently, the obstacles 4 can easily be cut by jetting abrasive-mixed, highly compressed water even in hard obstacles such as concrete.
