Definitions

  • the invention relates to a method for cutting rock, natural rock or the like with the aid of a jet of medium under high pressure, and to a device of this type according to the preambles of claims 1 and 6.
  • rock has been cut in such a way that blocks are removed from natural rock by blasting and these are e.g. with diamond saws.
  • Propulsion in the rock by a combination of mechanical devices in connection with water jets under high pressure is also known. From this, a method is also known for imparting rotation to a nozzle head with the aid of water under high pressure, which is supplied through a rigid lance, in order to achieve a drilling effect.
  • a disadvantage of this prior art is that either only holes can be drilled or that only cuts of small depth can be made.
  • a nozzle head having a nozzle in a straight longitudinal guide or on an axis of rotation and to ensure that the nozzle head moves in a straight line along the longitudinal guide or pivots about the pivot axis, for which purpose special drive devices are required.
  • Devices of this type are used, for example, for lifting asphalt coverings from road surfaces or for knocking concrete off the concrete reinforcements.
  • this device for cutting rock known from GB-A-2 027 776 is not possible if relatively narrow and deep cuts have to be made in the rock.
  • the drive devices known from GB-B-1 460 711 for driving the nozzle head also mean an undesirable special effort.
  • the object of the invention is to improve the method and the device of the type mentioned at the outset with simple means, which can also cut hard natural rock quickly and at low cost.
  • the medium under high pressure is itself used as a drive means for the nozzle or on one or more nozzles having a nozzle head, in which the medium sets the bendable supply line to the nozzle or nozzle head in a free-flowing movement, which is carried out by guides or stops is limited to a swivel angle. No swiveling shafts, pendulum drives or the like are required for this.
  • the movement path of the nozzle or the nozzle head is determined by a guide, so that not only straight cuts, as preferred, but also curved cuts can be carried out. It has been shown that this method offers numerous advantages in terms of handling, but also in terms of success, since there is practically no scrap apart from the cut material.
  • the medium under high pressure sets the nozzle or a nozzle head with nozzles in whip-like deflections which are limited by stops.
  • the medium under high pressure is preferably fed to the nozzle head through a flexible high-pressure hose.
  • the working pressure is e.g. between 400 and 3600 bar, preferably at about 600 bar, the pressure also having an influence on the working speed, i.e. on the speed of the movement of the nozzle head.
  • water is preferably used as the medium under high pressure, but it is also possible to use compressed air or compressed air in conjunction with solid particles and, if appropriate, water.
  • compressed air or compressed air in conjunction with solid particles and, if appropriate, water.
  • sand, quartz sand or iron shot can be considered as solid particles.
  • the device according to the invention has a feed line 1, preferably in the form of a flexible high-pressure hose, with a nozzle head 3 and nozzles 5, and a guide 6 with stops 4.
  • a feed line 1 preferably in the form of a flexible high-pressure hose, with a nozzle head 3 and nozzles 5, and a guide 6 with stops 4.
  • it preferably has a guide 2 which, together with the nozzle head 3 and in cooperation with the guide 6, leads to a controlled striking movement or vibration of the feed line and nozzle head between the stops 4 leads.
  • the nozzle head 3 with the nozzles 5, which can have different angles of attack with respect to the longitudinal axis of the feed line 1, represents the state of the art and can be designed according to the requirements; So it is sufficient with soft rock, such as sandstone, to leave the nozzles 5 at a relatively small angle of attack to the axis, while with harder rock a larger angle of attack will be chosen to shape the cutting width so that the guide 6 in the cut can be tracked.
  • the stops 4 consist of an elastic material that can take the form of rubber blocks or springs. With these stops 4, a longer service life, especially of the guide 6, is possible compared to an embodiment without such stops.
  • the guide 6 can, as shown in the figures, consist of a metal frame, but it can also have other shapes, for example a sieve-like reinforcement, through which the material removed by the cutting process can flow off with the pressure medium.
