  • the particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
  • FIG. 1a depicts a barren arch tunnel 1 , i.e., a tunnel without a liner.
  • FIG. lb depicts another embodiment of the present invention in form of a rectangular culvert.
  • Planar ceiling liner panel 2a with rebounding spacer 8a is positioned against the ceiling of the rectangular culvert with planar side panels 3a and 4a positioned against the walls of the rectangular culvert and engaging ceiling liner panel 2a.
  • ceiling liner panel 2a is lifted until rebounding spacer 8a is compressed sufficiently to allow planar side panels 3a and 4a to be placed under ceiling panel 2a.
  • a composition can be injected into the annular space between side panels 3a and 4a and the tunnel wall and any open space left in the annular space between ceiling liner panel 2a and the tunnel ceiling.
  • These compositions are well known to those skilled in the art and are used to fill in the spaces between the panels and the surfaces of the tunnel.
  • the compositions also can form a seal by filling the annular spaces behind the liners, thereby sealing the conduit or tunnel from water leaks.
  • These compositions include, but are not limited to grouts such as water-reactive expanding polyurethane grout, water-reactive gel-forming grout, epoxy hardening grout, cementitious grout and the like.
  • the annular space between the liner and the conduit or tunnel walls is left empty to be filled by infiltrating water carrying soil particles until the space is filled, thereby creating a fossil-like filler.
  • FIG. 2 depicts curved liner panels 2, 3, and 4 before installation, the larger central liner panel 2 having locking members 5 extending longitudinally along its opposite bottom edge regions.
  • These locking members can be formed in accordance with those made for connecting the longitudinal edges of an uncoiled sleeve in U.S. Patent No. 5,351 ,720.
  • the locking members can be created by means of a computer numerically controlled (CNC) machine by deforming the material of the sleeves at appropriately spaced locations to create projections along the edge regions, as shown, for example, in FIGS. 2 and 8.
  • CNC computer numerically controlled
  • a tunnel liner can be made of thick material that does not permit easy punching to form a locking member. In that instance, welded or mechanically attached locks may be used.
  • FIG. 3 depicts jack 6 positioned for receiving a liner, i.e., particularly central liner panel 2.
  • a liner i.e., particularly central liner panel 2.
  • scissors-type jack 6 is depicted, having an upwardly projecting curved support 7 for supporting the central liner panel 2 from below
  • the present invention is not limited to a scissors-type jack but can encompass other supporting and lifting devices that would perform the functions necessary for positioning and supporting the liner panels.
  • lifting devices include, but are not limited to, hydraulic jacks, screw type lifting jacks, hydraulic lifts, cranes and the like.
  • FIG. 4 depicts rebounding spacer 8, which is to be placed on the exterior wall of the liner panels.
  • Rebounding spacer 8 is positioned along the inner wall of tunnel 1 by any appropriate method known to those skilled in the art, including using jack 6.
  • Rebounding spacer 8 can be made of foam rubber or other resilient material. These materials include, but are not limited to, metallic meshes formed from spring steel and the like, foam materials formed in situ on the walls of the tunnels such as polyurethane foams and the like, metallic coils or springs and the like.
  • the rebounding spacer may comprise pumped-in concrete, or cement grout made with fine aggregate, which is capable of penetrating cracks and holes, if applied under pressure. While not shown, instead of utilizing a rebounding spacer that extends the complete length of the liner panels, it is contemplated that spacing members, such as the stop members of U.S. Patent No. 5,351 ,720, could border the longitudinal end regions of the liner panels, thereby defining a space for receiving grout or filler.
  • the rebounding spacers may also include hangers or spacers similar to the ones used in spacing and locating concrete forms.
  • FIG. 5 depicts tunnel 1 , which is lined with rebounding spacer 8 and is ready for application of the liner panels.
  • FIG. 6 depicts central liner panel 2, i.e., the ceiling panel, which is supported on jack 6. Jack 6 is operated to raise ceiling panel 2 until it is centered in place against the top inner wall of tunnel 1.
  • FIG. 7 depicts ceiling panel 2 maintained in position, with side panels 3 and 4 being brought to a position beneath respective bottom edges of ceiling panel 2.
  • FIG. 8 depicts side panels 3 and 4 positioned against the locking members 5 of ceiling panel 2, to thereby maintain a stress on the panels to assist in retaining the panels in position upon ultimate removal of jack 6.
  • FIG. 9 depicts a tunnel having both side panels 3 and 4 installed, the complete liner thereby extending from one side of the road bed, around the inner periphery of tunnel 1 , to the opposite side of the road bed.
  • FIG. 10 depicts jack 6, which is operated to lower the support from ceiling panel 2, so that jack 6 can be removed and repositioned for installing, e.g., additional sets of liner panels to be longitudinally positioned, through the length of the tunnel section.
  • rebounding spacers 8 such as strips of rubber, o-rings made of rubber and other rebounding material, or other sealing material, can be placed.
  • strips of sealing material can be overlapped one- half its width by one set of panel sections and one-half its width by another, longitudinally adjacent set of panel sections.
  • the rebounding spacer can be compressed by a lifting mechanism, such as jack 6. Leaving the space between ceiling panel 2 and the tunnel top compressed as the lifting mechanism is removed creates a seal for containing the filler.
  • sealants such as paste like materials that can cure into tight seals can be used.
  • a filter-like material can be used, thereby allowing soil-bearing water to pass through and forcing the solids to settle in the empty annular space between the liner and the walls of the tunnel.
  • FIG. 11 depicts a completed tunnel section as shown.
  • Ceiling panel 2 is maintained in position by opposite side panels 3 and 4. Any number of openings can be made in the ceiling panel and/or in the side panels, e.g. either before installation or after, for the purpose of installing lighting, electrical service, electrical communication, and/or providing access for the injection of grout.
  • the present invention has application in various environments, such as utility tunnels or railway tracks atop the bed of the roadway within a tunnel.
  • the tunnel can be lined with stainless steel liner, in three pieces from one side of the tunnel to the other.
  • ceiling panel 2 and side panels 3 and 4 can comprise smooth stainless steel liner panels, pre-cast concrete panels, reinforced concrete panels or fiber reinforced resin panels. It is also within the scope of the present invention to utilize other materials of construction or shapes for the panels. For example, such materials of construction could include plastics, aluminum alloys, and the like.
  • panels can be circumferentially corrugated to increase the effective stiffness and strength of the liner arch and/or the panels can be corrugated peripherally, i.e., from one side of the roadbed to the other, for increased strength and/or for enabling a reduction in the thickness of the material to be used.
  • the panels can be in sections which are joined together to form each side panel 3 and 4 and to form ceiling panel 2.
  • the panels can be made of hollow or filled hollow panels
  • a prefabricated relining system can be made. Such a system provides easy installation with least possible service interruption, i.e., a quick installation and completion. Also with a pre-fabricated relining system, no special skills are required and the equipment necessary for installation of the relining is available to those skilled in the art.
  • the equipment can include commercially available cranes, lifting platforms, fork-lifts or the like.
  • the present invention is an advance over prior art lining and relining techniques in that lining and/or relining of the present invention can be performed at reasonable cost. Further, the finished product, e.g. a lined conduit, is low maintenance and easily serviceable.
  • the liner of the present invention is durable, has a clean finish, and is long-lasting.
  • a liner made of stainless steel assures a clean and maintenance-free long-time performance with unmatched low overall cost.
