Machine and method for deconstructing a vertical wall

摘要

A machine and method are disclosed for deconstructing walls and other substantially vertical surfaces. The machine comprises a static, stand-alone support-frame. A carriage is movably mounted on the support-frame, which carriage can be raised and lowered along the support-frame. The carriage includes a carrier-bar, which may be straight or curved. One or more nozzles are mounted to the carrier-bar by means of a nozzle carrier that moves back and forth along the length of the carrier-bar. The nozzles are connected to a high-pressure supply of an erosive material, preferably water. The erosive material, when forced through the nozzles, form jet streams that are directed against the surface of the workface, thereby eroding the surface. Optionally, the invention comprises means of yawing and rotating the nozzles, and means of adjusting the nozzles towards or away from the workface. Optionally, the invention comprises a work platform mounted on the support-frame.

主权项

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.
