Definitions

  • the invention relates to a device for introducing a filling material into a hole in the ground.
  • the device comprises a channel-like filler device, which can be introduced into the hole and has an upper filling opening for filling the filling material and a lower outlet opening for discharging the filling material.
  • the invention further relates to a method for introducing a filling material into a hole in the bottom, in which a channel-like filling device is introduced into the hole, the filling material is filled into the filler device through an upper filling opening and is discharged or introduced into the hole via a lower outlet opening ,
  • Devices of the type mentioned are used in particular for the production of so-called bored piles, slats, sealing walls or the like.
  • a hole is first created in the ground, for example by drilling or milling.
  • the hole is usually supported by means of a support liquid.
  • the hole is filled from below with a backfill material, such as gypsum, gravel, sand or concrete.
  • the outlet opening is guided upwards in accordance with the rising level.
  • the support liquid is in this case displaced upward and usually deliberately dissipated.
  • DE 701 932 describes, for example, a pull-out bulk tube, which comprises a plurality of telescopically inserted into each other tube parts, of which the uppermost a concrete receiving hopper and the lowest has a muzzle.
  • a pour tube for introducing underwater concrete is in DE 1 113 427 described.
  • This bulk tube comprises a hopper and several associated, removable pipe sections, which can each be disassembled into two shells. During concreting, the pouring tube is pulled upwards. The shells of the uppermost pipe section are removed laterally so that the following pipe section can move upwards.
  • Another device and method for introducing a hardening mass under water is from the DE 1 928 993 known.
  • a flexible hose or shaft is used as the bulk tube, which is compressed under the action of the surrounding water pressure, so that a uniform outflow of the hardening mass can be realized under water.
  • the handling of the bulk tubes above the hole and the required devices are expensive.
  • the invention has for its object to provide an apparatus and a method for introducing a filling material in a hole in the ground, which allow a particularly economical backfilling.
  • the device according to the invention is characterized in that the filling device has an upper filling section and a flexible hose section arranged underneath, that the flexible hose section is movable upwardly along the filling section when filling the hole with the filling material and that a separating device is provided with which upper portion of the flexible tube portion is separable in its movement upwards along a longitudinal direction.
  • the method which is particularly suitable for producing a foundation or sealing element and in particular can be carried out by means of a device according to the invention, is characterized in that a flexible hose section of the filler device is moved upwards during filling of the hole along an upper filling section and that an upper Area of flexible tube section is separated when moving upwards by means of a severing device along a longitudinal direction.
  • a basic idea of the invention can be seen to provide a flexible bulk hose through which the backfill material is directed into a lower portion of the hole to be filled.
  • a hose has a low weight compared to a rigid pipe and can be manufactured cheaply.
  • Another basic idea of the invention is to separate the bulk hose at its upper end, in order in this way to achieve a shortening of the effective hose section through which the filling material is conducted. In addition, the handling when pulling out simplifies considerably.
  • the separation of the tube takes place during the filling of the hole when pulling up the hose, so that the hose length continuously shortens below the separation. Due to the continuous separation of the hose, the filling portion may be installed at a fixed position with respect to the hole.
  • the severing device may be fixedly arranged on the upper filler section of the filler device.
  • the flexible tube section can preferably be pulled up as a whole along the severing device and separated at the fixed position of the severing device. Behind the separation, the tube section is present as a split tube section or tube remnant. The separated hose residue can be directed away from the insertion section and recycled, for example.
  • a lateral access is provided in the wall, through which the filling material can be introduced into the tube section.
  • the access migrates along the tube due to the progressive separation, so that the length between access and lower tube end during the movement of the tube section is progressively shortened upward.
  • a guide section is formed on the insertion section of the filler device, which guides the tube section upwards during its movement and, in particular, feeds the separation device.
  • the guide section is preferably located below the separating device and may in particular be tubular.
  • the separation of the tube section can in principle be effected in any desired manner, for example by tearing open and / or pulling the tube along its longitudinal axis.
  • the separating device is designed as a cutting device with a cutting edge.
  • a reliable separation of the flexible tube section during its upward movement can be achieved by aligning the cutting edge of the cutting device downwards in the direction of a lower region of the filler device.
  • the cutting edge extends parallel to a longitudinal axis of the filler and is deliverable.
  • the filling section has a filling funnel.
  • the separating device for separating the flexible hose section is preferably arranged below the filling funnel.
  • the separating device below the filling funnel makes it possible to open or separate the flexible tube section below the filling funnel and to selectively pass it past the preferably permanently installed filling funnel.
  • a discharge section can be formed which leads the hose section away from or past the insertion funnel.
  • the filling section preferably comprises a guide section, along which the flexible tube section, in particular along its longitudinal axis, is displaceably guided.
  • the guide portion may comprise a tubular member which projects into the flexible tube portion and to which the flexible tube portion slides.
  • the filling section is preferably installed fixedly above the hole to be filled.
  • the filler device below the flexible hose section preferably has a particularly rigid pipe section on which the outlet opening is formed.
  • the pipe section fastened to the lower end of the disposable bulk hose is preferably reusable and is preferably detachably connected to the hose section for this purpose.
  • the reusable mouthpiece with outlet opening increases the economics of the apparatus and method.
  • the pipe section is preferably dimensioned so that it automatically aligns vertically due to its weight, so that a defined orientation of the outlet opening can be ensured.
  • a float can be attached to a lower portion of the filler, which is designed to lift the lower portion of the filler as a function of a degree of filling of the hole in the hole. It is particularly preferred in this case that the float is attached to the lower, in particular rigid pipe section of the filler device. In this way, a vertical alignment of the pipe section can be supported and reliable uniform discharge of the filling material from the filler device can be achieved.
  • a pull rope may be provided for lifting the flexible tube section.
  • the traction cable is preferably fastened to a lower region of the filler device, in particular to a lower end of the flexible hose and / or to the lower rigid pipe section below the hose.
  • a winch is provided for pulling and / or picking up the traction cable.
  • the pull cable runs outside or inside the flexible hose section of the filler device and is led out of the hose above the separating device.
  • the winch is preferably located laterally next to the filler device or next to the hole to be filled.
  • a fair submission is provided for determining a depth of a fastening point of the traction cable at the filler device.
  • the depth measurement allows a targeted tracking of the bulk hose.
  • a device for rolling up the separated, flexible hose section is preferably provided.
  • the retractor is preferably located laterally next to the bottom hole to be filled and may in particular include a winch or roller.
