Definitions

  • the invention relates to a method for sinking shafts. So far, shafts have been sunk in drilling and shooting operations or mechanized in partial or full cut, the shaft sinking device being able to be moved vertically by means of ropes and ashes.
  • the heap conveyance was carried out with a loading device that picks up the heap on the bottom of the shaft and with bucket conveyance that the heap will pass from the loading device.
  • the invention aims to use conventional cutting machines for sinking shafts and to simplify the sinking process.
  • the invention relates in particular to a method for Sinking manholes by means of a partial-cut cutting tool and consists essentially in the fact that the shaft uses a partial-cut cutting machine, which has a cutting arm that can be pivoted on all sides and has a crawler chassis, preferably designed as a crawler chassis, along a helical surface, the axis of which is to be sunk Shaft lies, is sunk, whereby the cutting machine is moved on the spiral surface. In this way it is possible to use a cutting machine which can be used for the extraction work in tunnels to sink the shaft.
  • the expensive and complex devices for the suspension of the heavy sinking device, which are in the Shaft must be lowered.
  • the cutting machine travels downward from helical gear to helical gear, the shaft being deepened further and further in the specified shaft axis. Since the cutting machine travels on the helical surface, it is also possible to sink inclined shafts in this way, since the axis of the helical gears must then simply be predefined accordingly. For example, it is easily possible to sink the shafts up to an inclination of 75 ° and more to the horizontal.
  • ballast can be applied to the front part of the cutting machine.
  • a conventional cutting machine is therefore preferably used, in which at least the majority of the parts projecting beyond the chassis, such as loading ramp, conveyor device and rear floor support, have been removed.
  • the slope of the helical surface is equal to the depth of the sole cuts achieved with the cutting machine in the same position.
  • Several sole cuts can be made 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, to Schr of the cutting head diameter.
  • the lowering depth of the cutting arm is limited and the cutting arm is also so inclined in the lowered position that it already comes into contact with the rock that has stopped after the first cut of the base. 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 bottom of the sole are expediently placed directly next to one another.
  • the helical surface is cut in sections in sections, the length of which 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 base cuts in the direction of the swivel radius. It can then be moved back and forth in each track when cutting a section, the cutting machine simply from sole cut to sole cut.
  • the method is preferably carried out in such a way 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 axis of the cutting machine with the tangent placed at the point of contact on the shaft wall includes an acute angle, and that after completion of the sole cut carried out in this position, the cutting machine moves backward in the direction of its axis one sole cut width and then the following sole cut is carried out until the swivel arm in its maximally pivoted position touches the shaft wall, from which Starting from the last sole cut of the section.
  • arcuate sections are 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. Since the machined helical surface itself forms the driving surface for the cutting machine, according to the invention the ribs between the sole cuts can be leveled with small cuts.
  • the cutting head or cutters are preferably driven according to the invention such that the chisels on the side facing away from the cutting machine go up and are moved down on the side facing the cutting machine. 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 by tubbings on the non-stable rock. Vertical ribs naturally remain on the shaft wall. The cut-out diameter should therefore be chosen so large that the segments can easily be inserted taking these ribs into account.
  • a conventional cutting machine can be used to carry out the method.
  • the cutting machine and the cutting arm there is between the vertical swivel mechanism the cutting machine and the cutting arm an angle piece is installed, through which the cutting arm is bent downwards relative to the swivel 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 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.
  • FIG. 1 shows a cutting machine in use for the method according to the invention.
  • Fig. 2 shows the implementation of the method when sinking a shaft.
  • the cutting machine i can be moved in the usual way 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 cutting arm 3 carries cutting heads 14 which rotate in the direction of the arrow 16 about a horizontal axis 15 lying perpendicular to the axis of the cutting arm 3.
  • the direction of rotation is selected so that the chisel is solicit from the cutting machine 1 turned side 17 up and down on the side facing the cutting machine 1 18.
  • 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 la, the center of the cutting machine being designated 8a and the pivot point of the cutting arm being designated 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 adjusted so that this axis 11a forms an acute angle 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.
  • the cutting machine is then moved 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 by a sole cutting width b and leads in this position the sole cut 21. 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 heads 14 are in the position 14b, in which they touch the shaft wall 9 when approximately the maximum cutting area is used.
  • an area 23 is thus cut out, which is circumscribed by line 22.
  • This surface 23 does not yet reach close to the axis 10 of the shaft.
  • the cutting machine is therefore pivoted about its vertical axis 8b from the longitudinal axis position 11a to a longitudinal axis position 11c from the position in which the machine center is in position 8b and the pivot axis is in position 4b, and is then advanced so far that the cutting heads 14 connect to the bottom cut 19 when the cutter arm is straightened.
  • a surface 24, which is framed by the line 25, is then cut in an analogous manner.
  • a section 23, 24 is now completed.
  • 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.
