Definitions

  • the invention relates to a method for producing a compression anchor through a wall that closes a floor with pressurized water, in particular sheet pile wall, and a device for carrying out this method with the features of the preambles of patent claims 1 and 7.
  • EP-A-0 218 987 discloses such a method and an apparatus for carrying out the method.
  • a core drill pipe sealed by means of a stuffing box and sealed on the air side is used for drilling an opening in the sheet pile wall for the subsequent insertion of a drill pipe for drilling the anchor hole.
  • a lock slide must be closed before pulling the core drill pipe out of the drill sluice. After inserting the drill pipe into the drilling lock, this gate valve can be opened again.
  • the drill pipe is closed with a drill tip or drill bit at the earth end.
  • an anchor rod with a claw device is inserted into the advancing pipe, which is driven in shots, at the end on the earth side.
  • this anchor rod is sealed with a sealing plate against the inner wall of the drill pipe.
  • an annular hose seal is still provided in the area of the anchor chair, which is attached to the anchor rod in a watertight manner, but is initially not activated by a pressure medium.
  • the pre-drive pipe is then filled with hardening material and pulled back briefly, so that the previously tight drilling tip remains in the ground.
  • the claw device of the anchor rod is stuck in the ground.
  • the borehole is filled up to the activated ring hose seal with constant repressing of hardening building material via the injection line and pulling back the drill pipe. Then the gate valve with gland and drill tube to be removed.
  • An anchor plate can now be placed on the rest of the anchor chair and an anchor head on the anchor rod.
  • the disadvantage here is that the production of the opening for the drill pipe by using a core drill pipe requires a cumbersome additional work phase with the additional use of a locking slide.
  • the attachment of a ring hose seal and a sealing plate to the anchor rod requires an appropriate assignment to the corresponding parts of the anchor chair.
  • the invention has for its object to improve this known method and device so that a simple creation of the anchor and a simpler design of the anchor chair used and the necessary sealing means is possible.
  • the invention offers the advantage that the creation of an opening for the drill pipe in the wall that closes the floor with pressurized water, for example a sheet pile wall, is simplified.
  • the seals in the anchor chair for the drill pipe and for the anchor tension member (s) are simplified.
  • the pressure medium can be easily and safely introduced into the ring hose seal via an outwardly directed valve.
  • the length of the anchor chair can also be shortened because the position of the ring hose seal can be precisely fixed.
  • the anchor can be made by drilling with a dense as well as with an open drill bit on the drill pipe or a drill bit with flushing channels.
  • the sheet pile wall 1 closes off a floor area 2 with a higher groundwater table.
  • This sheet pile 1 is intended to secure the ground pressure by means of grouting anchors.
  • the sheet pile wall 1 is provided with an only prepared opening 3 for the production of a compression anchor through the sheet pile wall 1. For this, e.g. cut the sheet pile into an elliptical shape according to the borehole to be created.
  • An anchor chair 4 is attached to the sheet pile wall 1, associated with such a prepared opening 3.
  • This anchor chair 4 consists of a base plate 5, which by means of screws 6 on welding studs previously attached to the sheet pile wall 1 on the Sheet pile 1 is attached.
  • Welded to the base plate 5 is a pipe socket 7 which is inclined, for example at an angle of 30 °.
  • This pipe socket 7 encloses an anchor lock 8.
  • a holding plate 9 is screwed onto the free socket end, for example by means of a stud bolt 10.
  • the holding plate 9 has a central passage opening 11. With the underside of this holding plate 9, an initially flattened hose ring seal 14 is fastened by means of a clamping ring 12 which is fastened to the holding plate by means of screws 13.
  • the hose ring seal 14 has a valve 15, the socket of which is guided through the pipe socket 7 to the outside.
  • the valve 15 can be connected to a pressure source (not shown) for a pressure medium. If this pressure medium is fed to the hose ring seal 15, the hose ring seal is inflated, as indicated by the broken line.
  • the hose ring seal 14 is formed by an overlapped band provided with beads 16.
  • the clamping ring 12 then has a corresponding holding groove 17.
  • the hose ring seal 14 either has a flat-shaped initial shape or this is forced by applying a vacuum.
  • a further base plate 18 is screwed to which a further pipe socket 19 is welded.
  • This base plate 18 also has a passage opening 20. It has a step-shaped edge 21 which covers the heads of the screws 13 while reducing the plate thickness.
  • a squeezable ring seal 22 is arranged adjacent to the base plate 18 and to the inner surface of the pipe socket 19.
  • a press ring 23 is arranged above the ring seal 22 and has a plurality of welded-on eyes 24. Screw bolts 25 are fastened to the outer circumference of the pipe socket 19. By tightening the nuts 26, the press ring 23 can be pressed against the ring seal 22.
  • a conventional drill pipe 30 is first inserted into the anchor stool 4 fastened to the sheet pile wall 1.
  • This drill pipe which is sealed at the end by a drill bit, is sunk with a conventional ram boring device.
  • the pinch seal 22 is suitably pressed against the outer wall of the drill pipe 30.
  • an anchor pulling member 31 is inserted into the drill pipe which is open at the rear end.
  • the anchor tension member 31 can consist of one or more anchor rods or strands. The anchor tension member is inserted up to the bottom end of the drill pipe 30.
  • this can be filled with hardening building material.
  • the drill pipe 30 is then closed on the air side with a compression cap.
  • the drill pipe 30 is withdrawn a short distance and then e.g. the drill bit can be detached by applying a high compression pressure to the building material in the drill pipe 30 by means of a piece of hose passed through the compression cap.
  • the drill bit can also be cut off by means of an inserted anchor tension member.
  • the anchor tension member is fixed in its position by the building material having a stiffer consistency.
  • the anchor tension member 31 has one or more post-injection channels, not shown, in the axial direction of the anchor tension member 31.
  • the channels have radial openings over the pressing section of the armature for the free exit of the injected, hardening building material which is injected after the primary building material has hardened.
  • a closed line must be provided over the free length of the anchor tension member.
  • a compression line fixed to the anchor can be provided for the primary building material.
  • the further injection of hardening building material takes place, as usual, by pulling back the drill pipe 30.
  • the hardening building material is then injected under pressure into the region of the drawn drill pipe 30 between the anchor pulling member 31 and the wall of the borehole 30, under pressure.
  • the annular hose seal 14 is now inflated by the pressure medium, which is supplied under pressure via the valve 15, as indicated by the broken line. It presses against the outer surface of the anchor tension member 31 or against the surrounding cladding tube and, if necessary, on external lines for supplying the hardening building material. By expanding the ring hose seal 14, the building material present in the anchor lock 4 is partially displaced.
  • An immediately hardenable, rubber-like material can also be used as the printing medium. This emerges from a print cartridge placed on the valve 15 of the armature lock 4.
  • a concrete wall can also be used. In this, the hole for the drill pipe is worked out while leaving a pierceable wall part.
  • drilling can also be done with an open rotary drill bit or with a full drill bit with irrigation channels or using the overlay drilling method.
  • the drill pipe is then closed on the air side and pressurized with compressed air before the installation of a new pipe section, the anchor installation and the injection of the liquid building material. This pushes the water away from the mouth of the borehole, far into the subsoil. The time until the water flows back is sufficient to carry out the aforementioned work steps. Filling the annular space between the drill pipe and anchor and injecting it into the subsoil when the drill pipe is withdrawn in sections is done in one operation.
  • the drill pipe 30 can be pulled out of the drill pipe lock 32.
  • a re-grouting can take place after the injected building material has hardened before the anchor head is put on by the post-injection line mentioned.
  • the change relates essentially to the anchor chair 4.
  • the hose ring seal 14 should be housed protected until it is intended to serve its sealing purposes.
  • the pipe socket 7 of the armature chair 4 is sealed by a single base plate 18 via an annular seal 42.
  • a pipe socket 40 is firmly connected to the base plate 18.
  • the edges of the hose ring seal 14 are fixed by clamping rings 12 fastened to the pipe socket 7 and by counter-clamping rings 41.
  • clamping rings 12 fastened to the pipe socket 7 and by counter-clamping rings 41.
