Definitions

  • the invention relates to a method for sinking shafts by means of a partial cutting shaving machine, which has a shaving arm that can be pivoted on all sides and carries a crawler chassis, preferably in the form of a crawler chassis, in which the shaft along a helical surface, the axis of which is in the axis of the shaft to be sunk lies, is sunk, whereby the cutting machine is moved on the spiral surface.
  • the invention aims to enable the use of conventional cutting machines for sinking shafts and to simplify the sinking process.
  • the invention essentially consists in that the helical surface is cut in sections in sections, that at the beginning of the cutting of a section the cutting machine is brought into a position in which the cutting head touches the shaft wall when the cutting arm is in the center, and in which the longitudinal axis of the cutting machine in the shaft cross section encloses an acute angle with the tangent at the point of contact to the shaft wall, and that after the sole cut made in this position by pivoting the cutting arm, the cutting machine in the direction of its axis travels one sole cutting width to the rear and thereupon the The following sole cut is carried out until the cutting arm touches the shaft wall in its maximally swiveled-out position, from which position the last sole cut of the section is carried out.
  • the shafts up to an inclination of 75 ° and more to the horizontal.
  • the area on which the cutting machine can be moved is limited by the diameter of the shaft to be sunk.
  • the method according to the invention is particularly simple to carry out, since during the cutting process, only the cutting machine is moved back in its track approximately by the width of the sole cut, the pivoting range of the cutting arm being best utilized.
  • the procedure is such that the length of the sections in the direction of the swivel arc of the cutting arm extends from the shaft wall to at least near the shaft axis and the width thereof corresponds to several bottom sections in the direction of the swivel radius.
  • ballast can advantageously be applied to the front part of the cutting machine.
  • a conventional cutting machine can be used, in which at least the majority of the parts projecting beyond the chassis, such as the loading ramp, conveyor and rear floor support, have been removed.
  • the slope of the helical surface can be chosen to be the same as the depth of the bottom cuts achieved with the cutting machine in the same position.
  • Several sole cuts can be carried out with the cutting machine in the unchanged position, the first sole cut being deepened by the following sole cuts.
  • only one sole cut is carried out in the unchanged position of the cutting machine, the depth of which is limited by the possible depth of penetration of the cutting head, which corresponds, for example, 3/4 of the cutting head diameter.
  • the lowering depth of the cutting arm is limited and the cutting arm is so inclined in the lowered position that it already comes into contact with the rock after the first cut. This is taken into account by the measure of only making one sole cut at a time. Apart from this the pitch of the helix is reduced in this way without increasing the amount of work.
  • the sole cuts are expediently placed directly against one another.
  • the cutting machine can be rotated about its vertical axis in the last position of the cutting machine, which is furthest to the rear, and the rest of the section in an analogous manner by making sole cuts which run essentially in the same direction as the sole cuts of the already cut part of the section. Since the cutting machine is moved from front to back, the easiest way to get it from this last position is to simply turn it around the vertical axis of the machine into the new position. In this way, arcuate sections can be cut, each of which extends from the shaft wall to the shaft axis or near the shaft axis.
  • the cutting machine is then brought into a new position which corresponds to the starting position when the first section is being cut and the next section is connected to the previous section, these sections being able to overlap.
  • the helical surface is scoured from gear to gear until the desired depth of the shaft is reached.
  • the cutting head or the cutting heads When using cutting machines, in which the cutting head or the cutting heads rotate about an axis which is horizontal and perpendicular to the cutting arm axis, the cutting head or cutters are preferably driven such that the chisels on the side facing away from the cutting machine and on the Side facing the cutter. This has the advantage that the cut pile is conveyed away from the machine and does not hinder the subsequent sole cut.
  • the shaft walls are clad in the usual way with segments.
  • Vertical ribs naturally remain on the shaft wall: the cut diameter must therefore be chosen so large that the segments can be easily inserted taking these ribs into account.
  • a conventional cutting machine can be used to carry out the method.
  • an angle piece is installed between the vertical swiveling mechanism of the cutting machine and the cutting arm, by means of which the cutting arm is bent downwards relative to the swiveling mechanism.
  • This has the advantage that the cutting arm is made steeper so that the cutting head can penetrate deeper into the sole without parts of the cutting arm colliding with the sole. Furthermore, the point of attack of the cutting head on the sole is moved closer to the machine, which increases stability. Overall, the largest possible undercut is made possible.
  • the cutter gear housed in the cutter arm is preferably equipped with circulating lubrication. This has the advantage that even with such a steep position of the cutting arm, all parts of the cutting gear are lubricated. When using splash lubrication, however, the lubricating oil would accumulate in the front area of the cutting arm in view of this steep position of the cutting arm, so that the lubrication in the rear area could be deficient.
  • the cutting machine 1 can be moved in the usual manner on caterpillars 2.
  • the cutting arm 3 can be pivoted about a vertical axis 4 and about a horizontal axis 5, so that it can be pivoted on all sides.
  • the cutter arm 3 carries cutter heads 14 which rotate in the direction of the arrow 16 about a horizontal axis 15 lying perpendicular to the axis of the cutter arm 3.
  • the direction of rotation is selected so that the chisels move upwards on the side 17 facing away from the cutting machine 1 and downwards on the side 18 facing the cutting machine 1.
  • 8 represents the central axis of the cutting machine 1.
  • an angle piece 6 is installed, so that the cutting arm 3 arrives in a downwardly bent position.
  • FIG. 2 9 indicates the circumference of the shaft to be sunk or the wall of the shaft.
  • 10 is the axis of the shaft to be sunk.
  • the top course of a spiral surface is made. Since the surface of the earth is mostly made of soft material, such as humus, this top course of the spiral surface can be made by hand or with excavators.
  • the use of the cutting machine is only necessary when you encounter rock.
  • the cutting machine 1 is thus set up in a position 1a, the center of the cutting machine being designated 8a and the pivot point of the cutting arm 4a.
  • the cutting arm 3 is aligned in the position 3a, in which it stands in the direction of the longitudinal axis 11, which is in the position 11a.
  • the position of the axis 11a must be set so that this axis axis forms an acute angle a with the tangent 13 placed at the intersection 12 on the shaft wall 9.
  • the cutting machine is advanced so far that the cutting heads 14 touch the shaft wall 9 in the position 14a. Starting from this position, the first sole cut 19 is carried out. Then the Cutting machine back in the direction of its axis 11, that is to say in its track, by a sole cut width b and executes the next sole cut 20 in this position. The cutting machine is then moved back again by a sole cut width b and executes the sole cut 21 in this position. In this position, the axis 8 of the cutting machine is in position 8b and the pivot axis of the cutting arm is in position 4b.
  • the cutting machine is then brought back into a new position in which the cutting heads touch the shaft wall when the cutting arm is aligned.
  • a subsection 26 is again cut in an analogous manner, which is indicated by a dash-dotted border 27 and a subsequent subsection 28, which is delimited by a dash-dotted line 29.
  • the next section 26, 28 is cut, which overlaps the previously cut section 23, 24.
