Definitions

  • the construction of large underground tunnels is usually accomplished by removal of material at the tunnel face by machine (or otherwise) and subsequently lining the exposed tunnel surface with prefabricated liner members as the tunnel progresses through the ground.
  • the tunnelling process will be assisted or in some instances made possible by the use of compressed air in the tunnel during the construction of the tunnel, as is usual in a plenum tunnelling process.
  • Pervious materials can cause problems for either of two reasons. In cases where the pervious material allows the air to flow directly to the atmosphere the pressure in the tunnel continuously escapes because the air leaks out, hitherto the only remedy has been to increase the air supply to the tunnel until the supply balances the leakage at the desired pressure. In cases where the pervious materials are totally enclosed by impervious materials, the pervious formation can fill up with air so that the air acts on the water within for formation and allows it to flow into the tunnel, no good solution has been found for this second problem in shield driven tunnels. Tunnellers have had to rely on various methods of face breasting with planks, straw, and other materials to restrain the flow.
  • This invention seeks to ameliorate and in some instances eliminate the problem of ingress of water and silt from the pervious strata during the driving of subterranean tunnels, and to control the air pressure and air consumption which have been characteristic of these tunnels.
  • the invention accomplishes its end by the use of a liner which is pervious to water and air but impervious to soil and sand. This is accomplished by providing a liner member for the tunnel which is provided with a recess in the face thereof, which is exposed to soil for the passage of moisture therethrough.
  • the recess will be provided with a foraminous substance in the form of a soil filter to allow the passage of water and air therethrough, but of a small enough size to prevent soil particles from passing therethrough.
  • a plurality of channels are provided in the recess beneath the filter medium which are connected to the through passage(s) which allow the water to pass through the tunnel liner member.
  • the through passages are connected to a suction line, that is, a system of conduits, the interior of which is at atmospheric pressure.
  • tunnel liner plate Although the word "plate” will be used, it is understood that the plate may be a prefabricated steel plate or a cast iron plate or a formed concrete block. All the above have been successfully used as primary tunnel lining members.
  • a tunnel liner plate 10 is shown to which this invention is applied.
  • This is a metallic plate of the usual arcuate shape to conform to the surface of the tunnel face. Suitable bolt holes are provided in the tunnel liner member for ready assemblage of the individual liner members into a complete tunnel lining.
  • Arcuate plate 10 is provided with a recess 12 as shown in Figure 2 so that the central portion of the surface facing the soil is somewhat recessed.
  • the recess is of a rectangular shape and in this instance the recess covers a majority of the area exposed to the tunnel face.
  • a foraminous filter 14 is of a nature which permits the flow of water therethrough, but will not allow the passage of soil particles therethrough, is placed in the recess above a grillwork 16. Grillwork 16 is provided to ensure that any water which passes through filter 14 will be provided with easy passage to the outlet conduit 18. Outlet 18 is connected to the "mop" or suction line in the tunnel plenum to allow any water passed through filter 14 to escape.
  • the use of the liner plates of this invention are used interchangably with standard liner plates of the usual impervious nature.
  • the plates of this invention may be interspersed as required with conventional liner plates or they may be used exclusively in the tunnel construction if the conditions warrant.
  • the plates of this invention may take a variety of forms as far as the filter portion of the liner is concerned.
  • the exposed filter surface may be made to be of almost any size as long as the structural strength of the liner plate is not impaired.
  • the filter medium may be of the treated cellulose fibers type which are widely available in a variety of pore sizes.
  • the filter medium is preferably glued to the liner plate at the periphery thereof for ease of handling and simplicity of installation.
  • suitable passages may be provided in the exterior surface of the liner plate by providing depressions in the liner surface for water flow from the peripheral areas to the interior of the liner plate where the exit conduit is located. It may be found in some instances that more than one exit conduit may be provided.
  • the liner plate 30 is provided with a recess 32 in which the foraminous filter medium 34 is glued and the recessed portion of the liner plate 34 is provided with a plurality of through holes such as the one shown at 36.
  • a shield 38 of a plastic or other suitable material is sealedly fitted to the inside surface of the liner plate.
  • Conduit 40 is again connected to the mop or suction line.
