Definitions

  • the present invention relates to an auto or self-locking coating for making road tunnels and the like.
  • a temporary supporting frame made of steel ribs, or a temporary lining made by bolting the wall rock in association with a great thickness of reinforced concrete, reinforced with a metal net, which must be anchored to the tunnel wall rock by means of bolts.
  • the lining operations are very complex and require a very long time and great amount of labour, with consequent practical making problems, depending on the lining method, in particular on the use of quoins(of reinforced concrete, stone and the like), metal plates or reinforced concrete to be directly poured during the boring of the road tunnel.
  • the aim of the present inven­tion is to overcome the above mentioned drawbacks, by providing a coating or lining for tunnels which can greatly simplify the lining operations of road tunnels which are finished after boring.
  • a main object of the present invention is to provide such a road tunnel lining which can be installed without using specifically designed mechanical apparatus and which can be quickly and safely applied to the walls and ceiling of the tunnels in very safe long lasting conditions for the operators.
  • Another object of the present invention is to provide such a road tunnel lining which can be made starting from easily available elements and materials and which, moreover, is very advantageous from a mere economic standpoint.
  • an auto-locking lining for road tunnels and the like characterized in that said lining comprises a plurality of preformed panels, made of a metal net grid assembly provided, on two opposite sides thereof, with coupling means for engaging with two longitudinal guides supported by ribs of a tunnel supporting frame.
  • the self-locking lining according to the present invention comprises a plurality of lining preformed panels 1, made of a metal net.
  • pannels are installed by means of manual means (a conventional hammer) and clamping fork members 2 can be further applied thereon.
  • the net lining panel contour has a generally C-shape pattern, with diverging legs 3, so that the lining panels can be arranged within the top arch of the tunnel to be lined, and are moreover provided with end portions 4 provided with loop patterns 5.
  • the metal net of the lining panels 1 has the wires 6 of the net links 7 rich are warped according to the tunnel axis made in a loop configu ration so as to provide eyelets 8 alternately arrang­ed above and under the contour of said lining panels 1.
  • lining panels 1 are installed by nesting or engaging before one of the end portions 4, and then the other, respectively with the loop 5, in the bottom leg 9 of one of the side guides 10, consisting of double-T metal beams.
  • These side guides 10, in particular, should be mounted, in a longitudinal direction, between two subsequent ribs of the road tunnel supporting frame.
  • the preformed panel lining is installed by using the mentioned locking fork members 2, which are designed and sized depending on the consistency of the rock to be supported.
  • clamping fork members 2 are manually threaded, two for each lining panel 1, from the central zone 11, in a cross direction, into the eyelets 8 formed by the net links 7.
  • the last step of the installing method consists of engaging each fork member 2 so as to contact the top leg 12 of one of the double-T guides 10.
  • the installation will be finished as the end portion 13 is arranged at the end of the leg 12, and the handle 14 engages with the net of the lining panel 1.
  • Figures 13 to 21 show a simplified embodiment of the lining panel, herein indicated by the reference number 101, in which said panel has a substantially trapezoidal configuration, with diverg­ing legs 102, so that this panel can be arranged within the arch 103 of the tunnel to be lined.
  • This panel affords the possibility of using a net having any desired link configuration and size, with great diameter net wires, specifically designed for supporting great loads.
  • This net structure is assembled by engag­ing at first one and then the other of the end portions 104 on the bottom inner leg 105 of side guides, indicat­ed at 106, which also in this case are advantagesouly formed by double-T metal beams 107.
  • the lining panels, either 1 or 101, of preformed metal net require a very small amount of metal material and can be made in a making shop by simple pressing operations, at a very reduced cost.
  • Another important aspect of the present inven strictly tion is that it provides a temporary lining adapted to operate as a safety supporting arrangement during the boring operations of the tunnel, without the use of heterogeneous materials very different from the reinforced concrete to be used for the finishing lining, this temporary lining being moreover adapted to efficiently cooperate with the reinforced concrete embedded therein.
  • the preformed panels as none spritz-­beton filling and reinforcement compound is used, can be easily recovered and reused.
  • the panels furthermore, can be specifically used, by properly fitting them, in association with ribs made of NP, HEB, G.I, T.H and the like ribs,
  • the used materials provided that they are compatible to the intended use, as well as the contingent shapes and size can be any according to requirements,
