Since the material is cut with ultra-high pressure water, it is possible to easily perform the crushing work such as crushing shearing in the next stage, and not only the upper and lower shear blades that are bent inward, but also the movable upper blade. Due to the synergistic effect of the tip of the unit and the pointed part of the fixed lower blade unit intersecting, crushing shearing or cutting work is performed by wrapping the FRP material or shaped steel material, so the FRP material etc. pops out during the work. It is possible to reliably prevent inconveniences such as falling off and falling off, so that the crushing process can be performed efficiently and inexpensively. Furthermore, fine dust of reinforcing materials such as glass fibers generated during lumping work can be reliably prevented from scattering to the surroundings by forming a water film by the water spray mechanism, so there is no fear of impairing the health of workers. And its practical effect is extremely large.
