Definitions

  • the invention relates to a method for tunneling in different geological formations, namely non-stable, uneven soils below the water table, the face constantly with the required back pressure through a medium such as water and / or a thixotropic liquid when propelling or air during pausing breaks, for example for repair purposes acted upon and in any case by means of a removal tool located in front of the printing plate, with the formation of overburden, whereby the mixture of overburden in the medium formed in the chamber between the working face and the printing plate is conveyed away and the mining space from the tunnel that has already been driven over in a pressure-tight manner the print shield can be sealed off.
  • a medium such as water and / or a thixotropic liquid when propelling or air during pausing breaks
  • the invention further relates to a device for carrying out the method with a pressure plate, with a removal tool attached in front of it in the direction of advance and with a conveying line for the flowable mixture, with a storage space, which is sealed off from the tunnel which has already been driven, in the direction of advance behind the pressure plate and which is arranged with the chamber is communicatively connected via an opening in the printing plate, the receiving-side end of a mechanical conveyor being arranged between the removal tool and the printing plate, which is led through the opening in the printing plate and extends with its discharge-side end into the storage space, and in which Storage space is connected to the mechanical conveyor a stone crusher, which is connected pressure-tight to the delivery line.
  • Such a method is carried out by means of known so-called hydroshield devices, which is particularly advantageous because the entire tunnel is only under atmospheric pressure and compressed air diseases of the operating personnel can thus be avoided.
  • the overburden contains, for example, stones, foreign bodies or other larger parts which, after accumulation of a certain volume must be manually removed from the chamber in front of the printing plate.
  • This is done in that the liquid level of the medium is lowered to the tunnel base by pumping and this extraction space or the chamber is placed under compressed air so that an operator can be introduced through the security gate into the space between the face and pressure wall to manually remove the larger parts to eliminate.
  • a device of the type mentioned at the outset can be found, for example, in DE-U-85 30 392, a stone crusher being additionally arranged in the storage space under the discharge end of the mechanical conveyor, on which a delivery line for liquid transport of the mixture is arranged, which is led out of the storage space in a pressure-tight manner to the tunnel that has already been driven, which should make it unnecessary for operating personnel to step in to remove coarse rock.
  • the invention is therefore based on the object of proposing a method and a device for carrying out the method, with which, even when larger parts, such as stones, foreign bodies or the like, occur, the tunnel can be continuously switched to dry transport in liquid transport, if necessary.
  • the method according to the invention is essentially characterized in that, for the purpose of liquid transport when the pressure shield is sealed off in a pressure-tight manner, the flowable mixture comprising water and / or the thixotropic liquid is preferably mechanically arranged in a direction of advance behind the pressure shield and communicating with the chamber via a
  • the first opening connected and from the tunnel that has already been driven in a pressure-tight manner is transported for the compressed air that the larger parts, such as stones, foreign bodies or the like, are separated from the mixture in the storage space and the separated larger parts are mechanically shredded and again in shredded form Mixture are supplied and the flowable mixture is transported away from the storage space in a pressure-tight manner via a delivery line, and that for the purpose of dry transport the pourable over
  • a device for carrying out the method is essentially based on the above-mentioned embodiment characterized in that a coarse sieve for the larger parts in the mixture is arranged above a collecting container for the sieve passage in the storage space under the discharge end of the mechanical conveyor Collection container a delivery line for liquid transport of the mixture is arranged, which is led out pressure-tight from the storage space to the tunnel that has already been driven, that the coarse screen is assigned a stone crusher for the screenings, which is connected to the delivery line, and that the storage space via a a second opening, closed by a closing door, can be opened towards the tunnel, a mechanical second conveyor being insertable through the second opening when the closing door is open, below the discharge end of the first conveyor.
  • the invention thus proposes a method and a device for carrying out the method in which the working face is supported hydrostatically, but the liquid level of the medium is not loaded under compressed air, as in known methods, between the pressure wall and a plunger wall arranged in front of it in which a pressure storage space led out through the first opening in the pressure plate, but otherwise sealed, takes over the function of the accumulator that is loaded with compressed air.
  • larger stones, boulders or the like which occasionally appear up to the bottom of the chamber or the tunnel bottom of the mining space, can occasionally transport larger stones, boulders or the like into the storage space, where they are separated and mechanically crushed and then returned to the liquid transport circuit are fed.
  • the construction of the device can also be kept shorter in the invention and the operating personnel introduced into the chamber through the personal lock can more easily get through the baffle not present there in order to carry out any repair or other work.
  • the storage space can be opened and a second mechanical conveyor can be introduced quickly and easily through the second opening that has become free, and preferably up to below the discharge end of the first mechanical conveyor in the storage space, so that continuous dry conveying to the available soil - dolly or the like can be performed.
  • the first conveyor is a screw conveyor, a belt conveyor or a chain or chain scraper conveyor, with a screw conveyor being able to compensate for earth pressure by selecting the pitch of the screw and the speed.
  • This is preferably supported by mechanically, hydraulically and / or pneumatically actuated support plates between the extraction arms.
  • the excavation tool has a multi-armed, conical drill head, which - while eliminating the center cutters available in the prior art - also causes centering when drilling the soil.
  • the device designated overall by 5, has a removal tool 6 arranged at the front in the direction of advance according to the directional arrow 7 and which has a plurality of drilling arms 8 on the drilling basket 9 which radiate from the center and which are provided with the actual drilling tools 10.
  • the drilling arms 8 span a conical surface and can be tilted and exchangeably arranged on the drilling basket 9.
  • the tilt axis can be arranged on the outer or inner abutment of the drill cage 9.
  • Support plates 11 that can be adjusted hydraulically, mechanically and / or pneumatically in the direction of drive forward and backward as well as adjustable can be arranged between the drilling arms 8.
  • the drill cage is arranged in front of the pressure plate denoted by 12 and driven by a drive denoted overall by 13, which is guided through the pressure plate 12 in a pressure-tight manner.
  • a double-chamber personal airlock 14 is arranged, through which one can get into the chamber, denoted overall by 15, between the removal tool 6 and the printing plate 12 can, which is sealed pressure-tight by the pressure shield 12 from the rear part of the device 5.
  • a storage space 16 is arranged behind the printing plate 12 and is located on the underside in the upper half 18 with respect to the longitudinal axis 17 of the device 5.
  • the storage space 16 is connected to the chamber * 15 via a first opening 19 in the printing plate and via a pipe 20.
  • the receiving end of a first mechanical conveyor designed as a chain conveyor 21 extends close to the bottom of the chamber 15 and is guided through the first opening 19 and the tube 20 to the storage space 16 in which its discharge end is arranged. * communicating
  • an inclined coarse sieve 23 is arranged above a collecting container 24 for the sieve passage, to which a conveying line 25 for liquid transport is connected.
  • a stone crusher 26 also with a collecting container, which is also connected to the delivery line 25 via a line 27.
  • the storage space 16 can also be connected to the tunnel 30, which is already supported by tubbings, via a second opening closed by a closing door 28.
  • a second mechanical conveyor 31 can be pushed through this second opening for the purpose of dry transport directly under the discharge end 22 of the chain conveyor 21, so that the excavated material can be transported directly into soil transport wagons or the like (not shown), the coarse sieve 23 if necessary must be omitted.
  • the tubbing 29 is transported to a tubbing conveyor 32 known per se in the direction of advance 7 to the actual device 5 and set there by means of an erector 33, which is also known per se. Feed presses 34 known per se are supported on the one hand on the tubbing already set, on the other hand on the device 5 or the printing plate 12.
  • a feed pump 35 for water and / or a thixotropic liquid is provided, which is led via a line 36 into the chamber 15 and exits there in the region of the first opening 19 via a flushing nozzle 37.
  • the first opening 19 can be sealed off in a pressure-tight manner by means of a slide which can be actuated mechanically, hydraulically or pneumatically and which is schematically designated 38 in order to also be able to carry out repair work in the storage space 16.
  • the crusher 26 is expediently only switched on when there is a certain amount of stone.
  • a level measuring device 40 for adjusting the air pressure 16 in the storage chamber can preferably be provided in the tube 20, which can then be exerted on the liquid surface and thus on the liquid filling the entire chamber 15 and thus on the working face in front of the removal tool 6 .
