Definitions

  • the present invention relates to a liquid shield for tunneling, consisting of a shield jacket and one in the area of the front seen in the direction of advance End of the shield shell arranged cutting wheel, being in the front area of the shield jacket with the help of a Pressure wall of a chamber partially filled with support fluid is formed by a baffle in the Cutting chamber with front cutting chamber and a rear one Chamber of Labor is divided by one recess opening formed by the baffle in the shield sole area communicates with the mining chamber and in which the support fluid using a compressed air cushion and an associated control device under a predetermined pressure can be set, the dated Cutting wheel extracted soil material together with Support fluid through the recess opening through a Stone crusher and through a rake over one in the area the delivery line leading to the pressure wall in the working chamber removable and the support fluid after removal of the soil material via a return line to the excavation chamber is traceable.
  • the support pressure control takes place of the type mentioned regularly such that the mining chamber is complete is filled with the support liquid, which mostly consists of a bentonite suspension.
  • the one behind the mining chamber lying working chamber is only partially with this Bentonite suspension filled.
  • the compressed air cushion Located above it the compressed air cushion.
  • the compressed air cushion is pressurized also the liquid in the working chamber under pressure set.
  • this pressure is based on the principle of communicating Tubes into the mining chamber so that the Support fluid in the area of the extraction chamber for support the face can be pressurized.
  • the opening also serves to promote the material soil removed by the cutting wheel.
  • a defined volume flow is generated via this delivery line the supporting fluid is withdrawn and a separating system fed.
  • the suspension is then returned to the mining chamber.
  • Stone blocks are to be excavated immediately a stone crusher behind the opening, usually a crusher or a jaw crusher, used, that breaks the stones and boulders down to an eligible level. This eligible measure is defined by the one in front of the intake pipe of the delivery line Rake with a defined opening width.
  • the object of the present invention is now this Material build-up in the sole area of the shield in the Prevent working chamber and in the mining chamber.
  • the solution to this problem according to the invention consists in that the shield sole area lying around the recess opening the Chamber of Labor through a between the Baffle and the partition wall arrangement extending is encapsulated in relation to the rest of the working chamber and the remaining working chamber through at least two supporting fluid lines is connected to the mining chamber.
  • the shield sole area is the work chamber encapsulated to a targeted Forced conveyance of the floor material to the suction nozzle to reach the delivery line. Stone crusher, rake and suction port of the delivery line are therefore encapsulated Area in which there are now no soil deposits can make more. Because of the encapsulation but the communication between the working chamber and the mining chamber to control the support pressure prevented. This Communication is now restored by the two additional support fluid lines. The result is so the function of soil material promotion from the function decoupled from the support pressure control.
  • the partition arrangement of about two radially from the shield sole to a central main bearing housing of the cutting wheel extending partition walls.
  • the supporting fluid lines are recommended in the range of the lowest of the rest Working chamber and above half the plate height in the Let the baffle open and / or in at least one of the two support fluid lines in particular a positive conveyor to be arranged in the form of a screw conveyor.
  • the opening as known through a sliding gate can be closed, e.g. a 1/3 lowering of the support fluid in the extraction chamber to be able to perform.
  • the same possibility opens up but also if, alternatively or in combination, in the Delivery line a gate valve is provided.
  • the partition to be provided with a pipe breakthrough that the encapsulated The sole of the working chamber is interspersed and the lower areas of the rest of the working chamber combines.
  • the liquid shield shown in the figures is for determines and consists of tunneling First build with a shield jacket 1 rear shield tail seal 2 and a cutting wheel 3, that in the area of the front seen in the direction of advance End of the shield shell 1 is arranged.
  • a Pressure wall 4 a partially filled with support liquid Chamber 5, 6 formed.
  • This chamber 5, 6 is in turn through a baffle 7 into a cutting wheel 3 front extraction chamber 5 and a working chamber behind it 6 shared.
  • the working chamber 6 projects through a the recess 7 formed in the shield sole area 8 with the mining chamber 5 in connection.
  • the Working chamber 6 is the supporting fluid with the help of a Compressed air cushion 9 and an associated, not shown Control device under a predetermined pressure settable.
  • the working chamber 6 is via compressed air locks 10 walkable.
  • the soil material extracted from the cutting wheel 3 is together with the support fluid through the recess opening 8 over a stone crusher 11 and through one subsequent rake 25 in the area of the pressure wall 4 conveying line 12 opening into the working chamber 6 can be removed.
  • the support fluid is after removal of the soil material via a return line 13 into the mining chamber 5 traceable.
  • this is around the recess opening 8 lying shield area 14 of the working chamber 6 by a between the Baffle 7 and the partition extending partition 15 encapsulated relative to the rest of the working chamber 16 and the latter through two supporting fluid lines 17 the mining chamber 5 connected.
  • the partition arrangement 15 of two approximately radially from the shield sole to a central main bearing housing 18 of the cutting wheel 3 extending partitions 19 formed.
  • the encapsulated sole area 14 of the working chamber 6 is through accessible flaps 20 in the partition arrangement 15 and / or pressure wall 4 accessible.
  • the support fluid lines 17 lead on the one hand in the area of the deepest of the remaining working chamber 16 and on the other hand above the half of the shield height in the baffle 7. Both supporting fluid lines 17 are in shape with a positive conveyor 21 a screw conveyor and with a slide slide 26 to close the respective support fluid lines 17 provided.
  • the recess opening 8 is through a baffle 22 closable.
  • 12 is in the delivery line a gate valve 23 is provided. Otherwise you can see in the partition arrangement 15 one formed by a tube Breakthrough 24 of the encapsulated thyroid area 14 penetrates the working chamber 6 above the rake and the two lower areas of the remaining working chamber 16 connects with each other.
