Abstract
A hydrodemolition rig for an inclined surface comprises a frame, a carriage, and a plurality of wheel assemblies. The wheel assemblies are spaced from one another about the frame, with at least two of the wheel assemblies comprising a wheel and a hydraulic assembly for selectively adjusting the spacing between the wheel and the frame. The carriage is configured to reciprocate within the frame and to carry one or more nozzles for delivering water for hydrodemolition.
Claims18
A hydrodemolition rig for an inclined surface comprising:
- a frame;
- a carriage configured to reciprocate within the frame and to carry one or more nozzles for delivering water to hydrodemolish the surface underlying the frame;
- and
- a plurality of wheel assemblies spaced from one another about the frame for supporting the frame on the surface, at least two of the wheel assemblies comprising:
- a wheel;
- and
- a hydraulic assembly for selectively adjusting a spacing between the wheel and the frame,
- wherein each hydraulic assembly adjusts the spacing between the respective wheel and the frame independently of the other hydraulic assemblies.
A hydrodemolition rig for an inclined surface comprising:
- one or more nozzle assemblies for delivering water for hydrodemolishing the inclined surface;
- and
- a plurality of wheel assemblies at various locations on a periphery of the hydrodemolition rig, wherein each of the wheel assemblies comprises:
- a wheel for travel along the inclined surface;
- and
- a hydraulic assembly connected to the wheel, wherein the hydraulic assembly is adapted to adjust a height of the hydrodemolition rig proximate to the respective location with respect to the wheel;
- wherein each of the hydraulic assemblies are configured to increase or decrease the height proximate to their respective locations independently of the other hydraulic assemblies.
A method of hydrodemolishing a surface of an inclined wall, the method comprising the steps of:
- providing on said inclined wall a hydrodemolition rig comprising a frame, at least one nozzle assembly and a plurality of wheel assemblies, each of said wheel assemblies comprising:
- a wheel;
- and
- a hydraulic assembly connected to the wheel and to a location on the frame, wherein the hydraulic assembly is adapted to adjust a height of the frame proximate to said location with respect to the wheel,
- directing said nozzle assembly to hydrodemolish a portion of said surface underlying said rig;
- moving said rig transversely about said wall to hydrodemolish a further portion of said surface, wherein said rig straddles a hydrodemolished portion of said surface and an undemolished portion of said surface yet to be treated;
- adjusting a tilt of the frame to orient the frame substantially parallel to said undemolished portion, by adjusting a height of said frame at at least one of said respective locations by means of said respective hydraulic assembly.
