Definitions

  • the invention relates to a method for retrofitting an underground waterproofing under a landfill according to the preamble of claim 1 and an apparatus for performing the method.
  • Such a method is the subject of EP-A-0 230 667.
  • two construction pits running parallel to one another are built at the edge of the landfill, the depth of which corresponds to the depth at which the landfill is to be passed.
  • the tunneling shield then drives underneath the landfill from one construction pit to the other, with soil being mined on its front. Soil is filled in at the back of the tunneling shield and a strip of a sealing layer is introduced.
  • the tunneling shield is supplied and disposed of through a tunnel pipe installed in this underpass, which is composed of individual tunnel pipe rings.
  • the tunneling shield Once the tunneling shield has reached the other excavation pit, it is moved through 180 ° and drives under the landfill in the direction of the one excavation pit, with an adjacent strip of a covering layer being introduced and at the same time the previously constructed tunnel tube being dismantled. After reaching one excavation pit, the tunneling shield is moved again by 180 ° and drives under the landfill as described above in the direction of the other excavation pit, with a new tunnel pipe being laid.
  • the disadvantage here is that when dismantling the tunnel tube, if the tunneling shield from one to the other Excavation pit moves, the dismantled tunnel pipe rings either have to be carried by the tunneling shield or have to be transported through the still existing piece of tunnel pipe.
  • the object is to improve the method in such a way that the dismantling of the tunnel tube does not pose any difficulties.
  • the method consists in laying a tunnel pipe at the foot of the landfill in a trench, along which a feed press moves along the side facing the landfill, which picks up the soil on the front and compresses it on the back, with one continuously on the back water-impermeable layer is introduced as a strip and the tube rings of the tunnel tube are continuously dismantled with the advance of the press and laterally offset to be reassembled to form a new tunnel tube.
  • the tunneling shield can be a film roll have, which unwinds continuously by the advancing movement of the sign, such that the film comes to rest under the landfill. Also continuously with the feed movement, the film is welded to the edge of the previously laid film.
  • the device is turned through 180 ° so that it can insert and weld the next film web under the landfill in the same way.
  • the tube rings of the tunnel tube are partially inclined, so that bending of the tunnel tube is possible by radial twisting.
  • the sealing base can be installed like a trough at the ends up to the surface of the earth under the landfill.
  • a personal pressure lock and an inlet funnel for mineral sealing materials which can be installed above and below the film, can be arranged.
  • Conveying devices for transporting the sealing materials are arranged inside the tube. The energy supply for the conveyor systems and the tunneling shield follow along the tunnel tube.
  • the tunnel tube can be filled with compressed air to retain any groundwater in the partially open tunneling shield.
  • the ventilation is done by pressure pipes.
  • the tunneling shield consists of a base plate and a cover plate that projects above it and is connected to a hydraulic cylinder.
  • the hydraulic cylinders are moved more or less quickly when the advance shield penetrates into the ground in order to reduce the roof pressure.
  • a horizontal feed press At the rear end is above the rolling film a horizontal feed press, behind the folded upper part of which the soil removed in front of the tunneling shield is filled and pressed.
  • the shield of the feed press on the back is made twice so that filter material (gravel) to be installed can be installed on the film surface.
  • the gravel is transported through the rear tunnel tube.
  • the clay to be installed under the film is transported along the tunnel tube on the front.
  • the top and bottom plates of the tunneling shield have movable knife shields at the front and rear end that enable horizontal control.
  • the vertical control is carried out by correspondingly different loading of the horizontal feed press and a hydraulic cylinder supported on the rear tunnel tube.
  • Another feature of the method is that the individual tunnel tube rings have a horizontal separation joint, so that these element halves can be transported along the tunnel tube and installed or removed in the tunneling shield in the event of length changes.
  • the individual tunnel tube rings can be watertightly connected to one another by means of automatically operated hydraulic quick releases.
  • the tunneling shield consisting of the roof plate 2 and the base plate 3, which are connected to one another via the vertical hydraulic cylinders 5. Knife plates 4a, 4b, can be pivoted on the plates 2, 3 at the front and rear in each case about horizontal axes, 4c and 4d arranged.
  • the rear feed press 6 has an upper, horizontally articulated plate 7. The plate 7 is actuated by a hydraulic cylinder 8. The feed takes place by means of the press 6 by actuating the hydraulic cylinder 9.
  • the film roll 10 rotates in the direction of the arrow 11, so that the film 12 comes to rest under the landfill 1. At 13, the film web 12 is welded to the film web 14 laid in the previous pass.
  • the tunneling shield moves in the direction of arrow 15.
  • the drainage material (gravel) to be installed on the film is transported through the rear tunnel tube and the clay 17 to be installed under the film is transported through the front tunnel tube.
  • the clay and the gravel are each introduced through a funnel 18 onto the conveyor belt in the tunnel tubes.
  • the personnel lock 19 at the end and beginning of the tunnel tubes hermetically seals them.
  • the tunnel tube rings 20 are alternately divided at an angle and connected to one another by hydraulic quick-releases 22.
  • 23 represents a clearing device for mining the soil.
  • the mined material is transported along arrow direction 24 behind the rear feed press 6 and its plate 7.
  • the tunnel tube ring 25 is moved along the arrow direction 26 in the position 25 'and there connected to the tunnel tube ring 28 by means of the hydraulic clamping devices 22.
  • the hydraulic cylinder 27 is supported on the ring 28.
  • 29 shows the horizontal parting line of the rings for separation in two half-shells. 29 'shows the offset of the parting line 29 in order to achieve the angling of the tunnel tube shown in FIG. 1.
  • 30 is the foil sealer.
  • a tunnel pipe consisting of the tunnel pipe rings 20 is laid along the landfill in an excavation pit, for example the upper tunnel pipe according to FIG. 2 . Gravel is applied to this part of the film 12.
  • the clearing device 23 can be moved horizontally and vertically between the plates 2 and 3.
  • the excavated soil reaches the plate 7 via a conveyor belt in the direction of arrow 24 and behind the press 6 to the gravel layer located on the film 12.
  • the last tunnel tube ring 20 is then transported between the plates 2, 3 in the direction of arrow 26 to form a further tunnel tube, in FIG. 2 the lower tunnel tube.
  • This procedure is now repeated, ie applying gravel to the further unwound film 12, Dismantling the soil next to one tunnel pipe in front of the tunneling shield, moving this soil behind the tunneling shield next to the other tunneling pipe, placing the clay layer in front of the tunneling shield and next to the one tunneling pipe, pressing the excavated soil behind the tunneling shield next to the other tunneling pipe while simultaneously advancing the tunneling shield and removal of the last tunnel tube ring from one tunnel tube and attachment to the further tunnel tube.
  • one tunnel pipe is dismantled and another tunnel pipe is built at the same time.
  • a layer of clay was introduced, a film was laid on the clay layer during the dismantling of this other tunnel tube and when laying the next tunnel tube, applied to this gravel and the mined soil compacted over this layer of gravel.
  • the tunneling shield When the excavated soil behind the tunneling shield is compacted, the tunneling shield can be pulled forward by hydraulic drives on one tunnel pipe and supported on the other tunnel pipe by the hydraulic cylinder 27, which promotes the feed movement in the direction of arrow 15.
  • the gravel can be fed through one tunnel pipe, while the clay is fed through the other tunnel pipe. Cleared soil can also be transported away via one of the two tunnel tubes, which is necessary if the cleared soil cannot be pressed sufficiently behind the tunneling shield.
  • Pipe system for suctioning seepage water This pipeline system is connected to a pump station and a treatment station, the latter being chemically treated in the latter. It is then fed anew to the surface of the landfill for washing out pollutants.
  • tunnel tube rings 20 alternately have an end face 21 that runs perpendicularly and obliquely to the tube axis, it is possible to bend the tunnel tube rings 20 about their axis, as shown in FIG. 1 on the right.
  • the cover plate 2 of the tunneling shield is preferably significantly larger than the base plate 3.
  • the tunneling shield has laterally movable shields 31.

Abstract

Pour pousser une presse d'alimentation (6), pourvue d'une bobine de film (10) se déroulant en continu, le long d'un conduit de tunnel constitué de différents tronçons et réalisé sous la décharge (1), on recueille la terre à l'extrémité avant et on la repousse vers l'extrémité arrière au moyen d'un piston de compression (9). Les différents tronçons du conduit de tunnel sont désolidarisés en continu des autres conduits par le mouvement d'avancement, puis, déplacés latéralement, sont rattachés à un conduit de tunnel faisant saillie derrière le dispositif. Les extrémités des conduits de tunnel sont munies de sas de décompression (19) et de sas pour les matériaux. La totalité du système peut être remplie d'air comprimé pour retenir la nappe phréatique. Ces conduits de tunnel servent simultanément de passage de sauvetage, de ventilation et permettent le transport de matériel.
