Definitions

  • the invention relates to a knife shield jacking device and a method for breaking out and / or finishing the construction of tunnels, tunnels, shafts or the like. Longitudinal structures, knives supported by support frames or guide bows being driven in succession and the support frames proceeding after all knives have been driven.
  • jacking knives are used which have lateral wedges.
  • the individual knives have a relative mobility with one another during the advance, so that curves or directional corrections can be made.
  • a disadvantage of this known device is that, in order to achieve a relative mobility during the feed for correction purposes, all jacking knives are always in a certain order, i.e. usually starting with the ridge knife and then continuously to the right and left of it.
  • This constructive sequence of advancing the individual tunneling knives which is not to be changed during tunneling, is disadvantageous if, for example, knives have to be driven in a different sequence in the case of uneven floors in order to secure the face.
  • a self-supporting support unit for small stud cross-sections which is formed from knife planks.
  • the knife planks are constantly rigidly guided to one another via dovetail-like guides, so that directional corrections which require the knives to move relative to one another cannot be carried out.
  • knife boards are also arranged on the tunnel sole, which greatly impairs the handling of this known device.
  • the invention has for its object to provide a method and a device with which an excavation and / or ready removal of a tunnel or the like. Without disruptive device parts and complex support frames is possible, a blade shield driving device is easily controllable, in which no tunneling knife is specified as the knife to be driven first and in which the tracking of the remaining knives can take place without additional precautions.
  • the guides on the jacking knives consist of wedge elements guided in brackets, and that in the front area of each jacking knife a fastening device is provided for a pressure device acting on an adjacent jacking knife. This ensures that a relative movement of the jacking knives with respect to one another is possible, that each jacking knife can be used as the knife to be driven first, and that the other knives take up their position parallel to the knife first driven without any communication effort.
  • a fastening device for a pressure device acting on an adjacent knife is provided in the front area of each tunneling knife.
  • two pressure units which in particular consist of piston-cylinder units, can be fastened via a quick-release fastener.
  • the brackets are U-shaped and a section is provided on the wedge elements, the width of which corresponds approximately to the distance between the legs of the U-bracket. This section is taken up by the legs of the U-shaped bracket when all knife ends lie in one plane, i.e. when all knives are advanced equally. In this position, all knives have a parallel position and are connected to each other with little play.
  • the wedge elements taper to both ends, starting from the section of constant width formed as a central section. This ensures that the knife to be driven first can be controlled to the right or left at the start of the advance movement and that the parallel knives to be driven thereafter are pivoted in the direction of the first knife by sliding the surfaces of the wedge elements on the legs of the U-bends.
  • a bracket is arranged on one side of each jacking knife and a wedge element is arranged on the other side, or a bracket is arranged on every second jacking knife and a wedge element is arranged on each side of every jacking knife in between.
  • all jacking knives can be designed identically, so that the storage and exchange of defective jacking knives are simplified.
  • the U-bracket is preferably open at the top and the wedge element engages between the legs of the bracket from above.
  • the wedge element on each jacking knife is preferably attached to the long side of the jacking knife via a cantilever plate.
  • wheel chocks are arranged on the jacking knives, which are arranged in the region of curvature of a tunnel cross section, between the U-bracket and the wedge element, so that the position of the bracket and wedge element is adapted to the tunnel cross-section.
  • the contacting inner surfaces of the bracket legs and the outer surfaces of the wedge element are preferably rounded.
  • the knives are mutually supported by lateral support members when the system is at rest and are self-supporting without a connection on the sole side.
  • a long, cross-sectionally T-shaped support member with a transverse leg pointing downward is arranged on one side of each knife, and a short, cross-sectionally U-shaped support member with upwardly directed legs is arranged on the other side of each knife, the L- Shaped support member of a knife engages in the U-shaped support member of an adjacent knife and on the T-shaped support member, starting from central sections of constant width, wedge-shaped run-up ramps are arranged.
  • the legs of the U-shaped support member rest on the regions of constant width of the T-shaped support member, so that the knives are in direct contact with one another.
  • an adjustable stop element is provided on the U-shaped support member.
  • This stop element can be designed in the form of a screw which, by screwing in and unscrewing, enables the play between the support members to be adjusted.
  • lifting devices acting on the sole-side knives are arranged transversely to the longitudinal axis of the knife and are designed in particular as hydraulic or pneumatic piston-cylinder units. After all the knives have been advanced, the lifting devices are actuated so that each knife can be brought into direct contact with the neighboring knife so that no uncontrolled movement of the knives towards the sole can take place after the support arches have been lowered. The pressure is then fed into the sole via the piston-cylinder units.
  • lifting devices are arranged on the guide arches or support frames at the ends on the sole side. With these lifting devices, the support arches can be lowered so that when the system is at rest, i.e. when the knives are self-supporting, the arches can be moved into a new support position. After a new arrangement, lifting devices are actuated and the upper side of the guide arches is brought into contact with the lower side of the knives so that the knives receive the required guidance during the advance.
  • the lifting devices on the support arches are preferably hydraulic or pneumatic piston-cylinder units.
  • guide elements are preferably arranged at the ends of the support frame on the sole side, which engage in guides arranged on base plates.
  • the lifting devices for the support frames are preferably arranged on the base plates, which enables that after Retracting the lifting devices when lowering the guide arches, the base plates are raised together with the guides in order to be moved with the guide arches.
  • engaging and displaceable struts are preferably provided in guides that can be laid on the sole.
  • the plates with the guides are raised at the same time and the struts are also supported on rails, so that the guide arches, which are then no longer in contact with the jacking knives, can be moved.
  • the pressure devices are preferably piston / cylinder units.
  • a method according to the invention in particular using a knife shield driving device according to the invention, is characterized in that when the system is at rest or after all the knives have been fed, the knives are placed in a mutual lateral position and become self-supporting, that the support frames are lowered and continue to advance, and that after the support frames are raised, the Knives are advanced again.
  • the knives supported by the support frames during the advance take over the support, i.e. when all the knives have been driven. they directly absorb the pressure exerted by the mountains and direct it into the tunnel floor. In this state, the guide arches or support frames can be lowered and continue to take over the support when the knives are advanced again. With this method, a second pair of support frames can therefore be dispensed with, which on the one hand makes the device more economical and on the other hand creates fewer obstacles during work. In addition, the knives can be made shorter, so that cornering or directional corrections are easily possible.
  • the knives are supported on both sides of the sole while they take over the support. No knives are arranged across the width of the sole.
  • each knife 10 to 18 has a U-shaped bracket 20 on its left side and wedge elements 22 and 24 on its right side.
  • the wedge elements 22 and 24 start from a central region 26 which has a constant width. From this area 26, the wedge elements 22 and 24 taper towards their opposite ends.
  • the wedge elements 22 and 24 together with the central section 26 form a longitudinal guide which is guided between the legs 26 and 28 of the U-shaped bracket 20.
  • the play between the knives 10 to 18 is almost zero, since the width of the middle section 26 is approximately equal to the distance between the legs 26 and 28 of the U-shaped bracket 20.
  • the guides 22, 24 , 26 form a wedge element 30, which is arranged below a cantilever plate 32, which is attached to the long side of a knife 10 to 18.
  • the wedge element 30 engages from above between the legs 26 and 28 of the upwardly open bracket 20.
  • FIG. 1 The position of the jacking knives 10 to 18 shown in FIG. 1 shows the starting position in front of a new jacking section. It is assumed that the tunneling knife 14, which can be arranged at any point in the tunnel cross section, is to be driven as the first knife.
  • hydraulic presses 34 and 36 in the form of piston-cylinder units are arranged on the knife 12 and on the knife 16, which are adjacent to the knife 14. Suitable devices for quick fastening of such hydraulic presses are provided on each longitudinal side of each knife 10 to 18. Two such hydraulic presses are sufficient for the direction-controlled advance of the advance meters 10 to 18.
  • Fig. 2 shows a cross section through the knives 10 to 14.
  • the knives consist of an upper wall 38 and a lower wall 40, which are connected to one another via side walls 42 and 44.
  • a guide bracket 20 is attached to the side wall 42 and a wedge element 30 is attached to the side wall 44 via a cantilever plate 32.
  • FIG. 3 shows the arrangement according to FIG. 1, the knife 14 being driven relative to the knives 10, 12, 16 and 18 via a hydraulic press, not shown. Since the hydraulic presses 34 and 36 are loaded equally, the knife 14 is driven parallel to the other knives.
  • FIG. 4 shows the arrangement according to FIG. 1, the knife 14 compared to the knives 10, 12, 16 and 18 was driven diagonally. Since after a driving distance, which corresponds approximately to the length of the central section 26 of the wedge element 30, a wedge of the wedge surface occurs in the U-shaped brackets, the knife 14 can be extended by extending the piston of the hydraulic press 34 and correspondingly retracting the piston of the hydraulic press 36 can be pivoted to the right.
  • the outer leg of the bracket 20 attached to the left side slides on the inner inclined surface of the wedge surface attached to the right side of the knife and the rear inner wedge surface of the wedge element 30 on the right side of the jacking knife 14 slides on the outer leg of the bracket 20 is arranged on the left side of the knife 16.
  • the hydraulic pressure cylinders on the knives 12 and 16 are removed and, starting with the knife 12, the knives arranged to the left of the knife 14 are driven in order, by sliding the wedge element on the knife 12 in the bracket on the knife 14, the knife 12 is automatically aligned parallel to the knife 14.
  • the knife 10 is aligned with the knife 12.
  • the knives present on the right of the knife 14 proceed from the knife 16.
  • This knife slides on with its bracket the wedge element 20 on the knife 14 until the outer leg of the bracket rests on the central portion of constant width of the wedge element and thus the knife 16 assumes a parallel position with respect to the knife 14. The movement of the knife 18 and any knives adjoining this knife take place accordingly.
  • a guide knife is therefore determined at the beginning of the knife advance depending on the circumstances.
  • This guide knife is first advanced and advanced in the desired direction with the help of hydraulic presses which are arranged on adjacent knives. Then the knives are advanced continuously to the right and left of the guide knife.
  • the U-shaped guides on one side of the knife cooperate with the wedge element attached to the neighboring knife, so that the advancing knife automatically aligns itself with the knife that has already been driven and comes into a position parallel to it. It is therefore sufficient to steer just any knife of the entire knife shield in the desired direction. All of the knives located to the right and left of this guide knife are then automatically brought into the direction determined by the guide knife during advance, without the need to report any deviated knives.
  • FIG. 5 shows a cross section through two knives 50 and 52.
  • the inner surfaces 56 and 58 of the upwardly directed legs 60 and 62 are rounded.
  • the outer surfaces 64 and 66 of wedge surfaces 68 and 70 of a wedge element 72 are also rounded in order to reduce frictional forces and constraints between the bracket 54 and the wedge element 72.
  • the wedge element 72 is fastened to the knife 50 via a cantilever plate 74.
  • FIG. 6 shows a cross section through two knives 80, 82, which are arranged in the region of a curvature of a tunnel cross section.
  • a wedge element 84 is fastened to the knife 80 and a guide bracket 86 is fastened to the knife 82.
  • a wedge 90 is arranged between the wedge element 84 and the side wall 88 of the knife 80 and a wedge 94 is arranged between the side wall 92 of the knife 82 and the guide bracket 86, whereby the contact surfaces of the guide bracket 86 and the wedge element 84 run parallel to one another, although the knife 82 is pivoted to the knife 80.
  • a guide bracket is arranged on one side of each knife and a wedge element on the other side of each knife.
  • the storage and replacement of knives, which have a guide bracket on one side and a wedge element on the other, is easier and therefore preferable.

  • the knives 110 to 136 are self-supporting, that is to say, by their mutual connection at the longitudinal edges, rock pressure forces are transferred into the bottom-side knives 110 and 136 and there via the piston / cylinder units 138 and 140 into the Transfer sole.
  • the knives are self-supporting and absorb the rock pressure and discharge them into the sole.
  • the support frames or guide arches 142 and 144 which are connected to one another via piston / cylinder units 180 are arranged in a position under the knives 110 to 136 (knife 124 is shown), from which the knives are driven for the further outbreak.

  • the guide arch 142 By pulling in the piston of the piston / cylinder unit 180, the guide arch 142 is displaced towards the guide arch 144. In the next possible position of the guide arch 142 to the guide arch 144, the piston / cylinder units of the guide arch 142 are actuated again and the guide arch 142 is raised, whereby it comes into contact with the underside of the knives 110 to 136. Thereafter, the guide bow 144 is lowered and moved by advancing the piston of the piston / cylinder unit 180 in the direction of advance until it comes under the front end of the knife. 11 shows the position in which the guide arch 144 has been raised again so that it can take over the guidance of the knives to be re-driven together with the guide arch 142. As can be seen from FIGS.
  • the guide arches 142 and 144 are alternately in a support and in a traveling position.
  • the support elements arranged between the individual knives are only effective when all knives 110 to 136 of the hood have been displaced and in this stage the knife hood takes over the function of a self-supporting unit.
  • the self-supporting function of the knife hood is released in order to enable the relative mobility of the knives among one another in the circumferential direction of the knife hood, which is required for cornering and directional corrections.
  • FIGS. 12 and 13 shows a top view, for example, of the longitudinal edges of the knives 122 and 124 arranged next to one another. Approximately in the region of the position on that of the guide arch 144 in FIG. 8 and in the region of the position of the guide arch 142 in FIG. 9 are on the longitudinal sides of the knives 122 and 124 support members 190 and 192, respectively.

  • the area 220 and the run-up ramps 222 and 224 are semicircular in cross section, so that a linear load is achieved with the inside of the leg 196 of the support member 190.
  • the rounded or hemispherical design of the head 206 of the screw 202 and the semicircular design of the run-up ramps 222 and 224 as well as the central region 220 enable the knives to be mutually supported when the knives are rotated in the arcuate shape of the support frames 142, 144 .
  • Knives or knife-like formwork planks with lateral support members and guide arches can also be used in the concreting area of a tunnel in the same way as in the excavation area. Due to the self-supporting function of the knives or formwork planks, an obstructive support or a scaffolding can be dispensed with.
