Definitions

  • the present invention relates to a method and a Device for stabilizing one in underground mining broken cavity according to the preamble of Claim 1 or 10. This method and this device preferably used in bad, pressure mountains with low strength.
  • This known tunnel lining has some practical Disadvantage. In the area of the end faces of the compression tubes occurs in the lining segments a local Stress concentration on. It must therefore except the Installing the pressure transfer plates further precautions be taken so that the lining segments because of this Stress concentration can not be damaged. That affects also detrimental to the costs. With a lining off Shotcrete also has to be manufactured during the production process Contraction joint against the penetration of shotcrete to be protected. Next may be a possible misalignment the compression tubes due to transverse movements of the Lining segments relative to each other cause problems.
  • the present invention is based on the object, a method and a device of the type mentioned to create, which makes it possible to simpler and easier cost-effective manner the exerted on the proppant Pressure some resistance under approval of To counteract deformations.
  • the dimensions and mechanical properties of the Compression body can be easily attached to the respective Adapt requirements.
  • the compression body as a in Direction transverse to the applied compressive forces elongated structure be designed so that the danger a concentration of stress in the support means avoided becomes.
  • Tunneling 1 consists of two serving as proppant Tunnel removal elements 2 and 3. With the arrow C is the last Built-in stage called.
  • the Tunnelausbauium 2, 3, the made of shotcrete, cast-in-situ concrete or prefabricated Concrete elements are made, take the pressure through the deformations of the tunnel cavity 4 surrounding mountains 5 is caused on.
  • the Tunnelausbauium 2, 3 are by a gap running in the tunnel longitudinal direction 6 (contraction joint) separated.
  • elongated compression body 7 are arranged, the Fill the gap 6 practically completely.
  • the compression bodies 7 have a length which Length of an installation stage C corresponds.
  • Each Stauchgroper 7 consists of a material with a certain volume fraction of voids, throughout Stuffer body 7 are distributed.
  • the cavities are at the Production of the compression body 7 introduced targeted.
  • the Upset body 7 in particular has a compressive strength of at least 1 MPa and a void fraction of 10 to 90% of his total volume.
  • the compression body 7 preferably, a compressive strength of at least 3 MPa and a Void content of 20 to 70%.
  • the compression body 7 should can withstand a certain pressure load, but when exceeding a certain pressure load deform relatively strongly. This deformation happens for the most part, that the cavities gradually in collapse or gradually compressed become.
  • the cavities of the compression body 7 can be closed or open and partially or completely interconnected. These cavities can also be elongated, a have cylindrical or prismatic shape and arranged so be that their longitudinal axes parallel to each other and preferably at right angles to the axis of the pressure load run. In this way, results in a compression body 7 with honeycomb structure.
  • the compression body 7 consist in a first embodiment from a porous metal foam, but preferably from Steel foam, and may e.g. after in DE-C-197 16 514 be prepared described methods. Made of metal foam Existing bodies and their manufacture are also in Wo-A-00/55567 described.
  • To form the cavities can instead of Blähglaspumblen also particles from another suitable Material, e.g. Plastic or steel foam, to be used. It is also possible to combine one or more of these materials. So it is possible, for example To use polystyrene grains.
  • the cavities can also through the use of a propellant in the manufacture of the Upsetting body 7 causes the generation of gas bubbles, be formed. While the expanded glass particles a Compressing the compression body 7 a certain resistance Opposite, this is hardly the case with styrofoam grains.
  • a raw material instead of cement, also a Plastic, such as a synthetic resin can be used.
  • FIGs. 3 and 4 an area of the tunnel construction with the Compression body 7 in unloaded or loaded state shown, wherein the compressive force acting on the compression body 7 with N, its cross-sectional area with F and the height of the Compression body 7 in the unloaded state with d and in loaded state is denoted by d '.
  • Figs. 1 to 4 are the compression body 7 between the tunnel extension elements 2, 3rd arranged without them in addition to the Expansion elements 2, 3 are connected.
  • these surfaces 7a, 7b also obliquely to each other, i. forming an angle with each other, to be ordered.
  • the compression elements 7 then have a Wedge shape.
  • the compression elements 7 are so in the space 6 incorporated that the surfaces 7a, 7b in the direction of the mountains 5 diverge.
  • Figs. 6 to 8 are now different ways to additional connection of the compression body 7 with the respective adjacent expansion element 2 or 3 shown.
  • Fig. 6 shows a tongue and groove connection, wherein the Compression body 7 is provided with projecting strips 8, the engage in recesses 9 in the expansion element 2 and 3 respectively. It is also possible, the recesses on the compression body 7 and the Last to provide the tunnel extension elements 2, 3.
  • Embodiment of a tunnel lining 1 are called proppant instead of the tunnel construction elements 2, 3 steel beams 12 and 13 used in the tunnel longitudinal direction in each case in certain Be installed intervals (see Fig. 9).
  • interacting Steel beams 12, 13 are the same as in the embodiment according to FIGS. 1 and 2 by a gap. 6 separated from each other, in each case a compression body. 7 is used.
  • These compression body 7 correspond in structure and the mode of operation with reference to FIGS. 1 to 5 described compression bodies 7 and are only in their Shape adapted to the slightly different proportions.
  • FIG. 11 shows a possibility for connecting the Upset body 7 with the adjacent steel beams 12, 13th This connection is offset in the tunnel longitudinal direction arranged head bolt 14 ensured.
  • FIG. 12 a third embodiment of a Described Tunnelausbau 1, fixed in the mountains 5 Anchor 15 can be used.
  • the anchor 15 is with his Anchor rod 16 in the mountains 5 firmly anchored, e.g. mechanically or by mortaring.
  • a compression body 7 is installed, which in the In connection with FIGS. 1 to 5 described compression body equivalent.
  • the compression body 7 is between two Steel discs 18 and 19 arranged.
  • step-by-step collapse or compression of the cavities in the interior of the compression body 7 under load in a very specific, controlled manner he follows.
  • a controlled behavior of Compression body 7 under pressure load can be achieved be that in the compression bodies 7 by a corresponding Shape of the compression body 7 or by suitable measures during their manufacture, e.g. by providing Weak points, an inhomogeneous stress state generated becomes.
  • the compression bodies 7 can also be provided with at least one plate or lattice-shaped reinforcing element be provided transversely and preferably at right angles to the loading direction (Effective direction of the compressive force N in FIGS. 3 and 4) runs.
  • This reinforcing element which has a high mechanical Strength can be found in the base material of Be embedded compression body 7.
  • the Upset 7 is the Upset 7 as a multilayer composite formed, in each case a layer of a Partial body made of a material containing the cavities exists, with a plate or lattice-like Reinforcement element alternates.
  • the reinforcement elements can the compression behavior of the compression body 7 at Pressure load can be favorably influenced.
  • Support means or extensions 1 not only in tunneling, but can generally be used in underground mining.
