Abstract
Apparatus for cutting erosive materials such as stone and the like includes a high-velocity, high-pressure water lance which can be raised and lowered as necessary. The lower end of the water lance carries a cutting head in the form of a nozzle assembly able to be rotated about the longitudinal axis of the water lance. The water lance is mounted upon a carriage which can be propelled in directions at right angles to each other and the water lance may be supported by a vertically-disposed truss, which itself may be relocatable about the longitudinal axis of the lance.
Claims13
Apparatus for accurate cutting of erosive materials, using hydraulic means along, comprising a rigid high velocity, high pressure water lance, said water lance including a water directing cutting head at the lower end thereof,
- means for selectively translocating said lance and head about 3 independent axes with respect to a surface of the material to be cut, and
- wherein said water lance is further supported by a truss which is able to be swung into at least three different positions relative to said water lance.
Apparatus for accurate cutting of erosive materials, using hydraulic means alone, comprising only one rigid high velocity, high pressure water lance, said water lance including a water directing cutting head at the lower end thereof,
- means for selectively translocating said lance and head about 3 independent axes with respect to a surface of the material to be cut, and
- wherein said cutting head has a horizontal conduit extending therefrom for the making of undercuts.
Apparatus adapted for accurate cutting of erosive materials, using hydraulic means alone, comprising only one rigid high velocity water lance, said water lance including a water directing cutting head at the lower end thereof, and means for selectively translocating said water lance and cutting head about 3 independent axes with respect to a surface to be cut, so as to allow said cutting head to operatively cut in 3 substantially perpendicular planes within a body of material and hence permitting the removal of said erosive material in block form.
