Definitions

  • the invention relates to a method for setting a rod, wire or tubular installation part, e.g. an anchor rod for a grouting anchor, through a wall, in particular a sheet pile wall into a ground formation with pressurized water, a device being attached to or in the sheet pile wall, which has an opening with a first seal, through this opening a pre-drive pipe with waterproof, lost Tip is driven in watertight, the built-in part is inserted into the pre-drive tube, the pre-drive tube is pulled and the resulting cavity with a grout, for example a hardening material is pressed, a second seal between the pre-drive pipe and the built-in part preventing the escape of pressing water, as well as devices for carrying out this method.
  • a rod, wire or tubular installation part e.g. an anchor rod for a grouting anchor
  • a method and a device of this type for use in concrete slotted walls or the like is known for example from German Offenlegungsschrift 23 54 764.
  • a special bushing is concreted in, which has at least one, preferably two sealing rings.
  • a pre-drive pipe with a waterproof tip is then first driven to the desired depth.
  • the actual built-in part for example a tension member for a compression anchor, is then inserted into the pre-drive tube, a second seal between the anchor tension member and the pre-drive tube preventing pressing water from escaping.
  • the pre-drive pipe is then pulled, the tip of which remains in the ground; at the same time the cavity in the ground is pressed with a hardening material.
  • the sealing ring which is located in the bushing, must be designed so that it is not only so far compared to the pre-drive tube, but after pulling the same against the anchor pulling member seals that escaping the pressing water is reliably prevented.
  • the cross sections of the pre-drive tube and anchor tension member should therefore differ from one another as little as possible.
  • the final seal between the bushing sleeve and the anchor tension member is achieved by a special cylindrical sealing ring which is pressed together by means of an annular disc and a sleeve in the axial direction so far that it finally seals the gap between the bushing sleeve and the anchor tension member.
  • the pre-drive tube is retracted until its end is approximately in the middle of the bushing.
  • the cavity between the anchor tension member and the bushing is then pressed with plastic via a compression line previously concreted into the slot wall.
  • This plastic plug is intended to prevent the pressurized water from escaping when the pre-drive pipe is completely pulled out.
  • the final sealing is again carried out by a cylindrical sealing ring, which is pressed together in the axial direction with the help of an annular disc and a sleeve so that it finally seals the space between the bushing and the anchor tension member.
  • the invention is based on the object of specifying a method which is suitable for all types of walls, but in particular for steel sheet piling, and in which provides greater security against a possible escape of pressurized water.
  • this object is achieved procedurally by first reinforcing the sheet pile, then assembling the device with the first seal and making the opening in the sheet pile so that the grout, e.g. Hardening material is formed to form a grouting body up to a third seal, which is effectively in front of the second seal and that finally the cavity between the third seal and the sheet pile wall also with grout, e.g. with hardening material, is pressed.
  • the grout e.g. Hardening material
  • hardening material is injected behind it to reinforce the sheet pile wall, which material forms a plug that acts as a third seal.
  • an opening can be created in the sheet pile wall and a base plate provided with an opening and a circumferential seal can be mounted on or in this opening as the first seal.
  • the stopper not only forms a reinforcement of the sheet pile wall, but also forms a seal, so that the sheet pile wall can then be easily drilled through. If the plug is then also pierced, the sealing against the pressurized water is brought about by the base plate, which forms a kind of gland.
  • the base plate which forms a kind of gland.
  • a drilling lock is attached to the wall, which consists of a base plate with a connecting pipe piece, a gate valve and a stuffing box as the first seal; Then the sheet pile wall is pierced by means of a waterproof core drill pipe, which is guided through the stuffing box.After its retraction until the pilot pipe is inserted, the gate valve prevents water from escaping, and finally, with the installation part as a third seal, an activatable seal is installed, which after pulling the pilot pipe is activated and the borehole seals against the connecting pipe piece.
  • the gate valve and the gland can be dismantled and replaced by anchoring of the installation part acting against an anchor plate.
  • the final third seal is an activatable seal that can be installed with the installation part and activated later.
  • the compression body can be brought up to this seal directly.
  • Such a device suitable for carrying out the first method variant consists of a base plate to be fastened to the sheet pile wall in a watertight manner, with an opening surrounded by a circumferential seal in the manner of a stuffing box.
  • This base plate can have at least one valve for pressing in hardening material.
  • a device which is made possible by a drill sluice which is to be watertightly fastened to the sheet pile wall and consists of a base plate with an opening to which a connecting pipe piece, a gate valve and a stuffing box are attached and between the gate valve and the stuffing box a centerable bearing for a core drill pipe may be arranged.
  • an activatable seal is expediently fastened on the mounting part as a third seal, which lies in the lowered state of the mounting part in the region of the connecting pipe, while openings are provided in the activatable seal for the tight passage of a compression line and, if appropriate, a post-compression line and the associated ventilation openings .
  • a sealing plate is expediently placed tightly on the built-in part as a second seal, which seals against the inner wall of the pre-drive pipe and in which openings are provided for the sealed passage of a compression line and optionally a post-compression line and ventilation openings.
  • This sealing plate has on its outer circumference a sealing ring inserted into a circumferential groove. The ventilation openings can be closable.
  • a suitable device in the form of a working chamber designed as a watertight room cell for carrying out and continuing work even under water is distinguished by a room cell which can be lowered into the water and can be connected tightly to the sheet pile wall and which has a working opening in the outer wall facing the sheet pile wall, whereby at least one circumferential seal made of elastic material is arranged around this working opening and the profile of the outer wall of the room cell facing the sheet pile wall and the seals are adapted to the profile of the sheet pile wall.
  • seals arranged parallel to one another are expediently provided and the intermediate space formed between them can be drained.
  • the seals themselves can be arranged on a sealing frame which can be attached to the outer wall of the room cell in a watertight manner, enclosing the working opening. This creates the prerequisite for the seal to be adaptable to different sheet piling profiles.
  • the working opening can be closed watertight from the inside by a closure plate.
  • the room cell itself can be attached to a hanging device and ballasted. It can also be provided with pressing devices for positioning against the sheet pile wall.
