Abstract:
1. A hydrodemolition machine for deconstructing a portion of a curved vertical wall of a building when the hydrodemolition machine is placed adjacent the wall, the hydrodemolition machine comprising: a static support frame assembly for placement adjacent the wall, the static support frame assembly having at least two opposed vertical members; a curved carrier-bar, opposed ends of said carrier-bar being movably connected to respective ones of said two vertical members so that said curved carrier-bar extends between said two vertical members so as to span substantially across the frame assembly, the curved carrier-bar being operative to move vertically along and between said two vertical members; and a nozzle assembly movably mounted on the curved carrier-bar and being operative to move along the curved carrier-bar between said vertical members, the nozzle assembly being operative to emit a jet of fluid against the wall of sufficient velocity to remove concrete from the wall.
