Definitions

  • This invention relates to an edge seal assembly and more particularly but not exclusively to such an assembly for a tunnel lining or pipeline which is made up of members arranged edge to edge, which edge joint requires sealing against the ingress or egress of fluid, usually liquid.
  • the gasket is subjected to fluid pressure in a transverse direction and sometimes fluid can leak past the gasket.
  • a gasket for an edge seal assembly which is of constant thickness but has a first part which is received in a recess of one member, and a second part which is received in a recess of the second member, each of the first and second parts decreasing in width in a direction extending into the recess.
  • an edge seal assembly including a first member having intrados and extrados side surfaces and a first edge between the side surfaces, and a second member having intrados and extrados side surfaces and a second edge between the side surfaces, each of the first and second edges in use facing one another and at least one of the edges having a recess, and there being a gasket receivable between the first and second edges and being receivable in part in the recess characterised in that the thickness of the gasket decreases from a thicker region which is positioned more closely adjacent the intrados or extrados side surfaces, to a thinner region which is positioned more closely adjacent the extrados or intrados side surfaces respectively.
  • the gasket may be arranged such that the thickness of the gasket decreases from a side more closely adjacent to the intrados or extrados side surfaces which are in use exposed to the greater fluid pressure.
  • the gasket may thus include a first part the thickness of which decreases from a thicker region which is positioned more closely adjacent to the intrados side surfaces to the thinner region, and a second part the thickness of which decreases from a thicker region which is positioned more closely the adjacent the extrados side surfaces such that the gasket has a reduced thickness in a region between the thicker regions.
  • the effect of the fluid pressure from the extrados or intrados surface is to urge the thicker region or regions of the gasket away from the surface or respective surface thereof.
  • the recess in the edge of the first or second member decreases in depth from a side more closely adjacent to intrados and/or extrados side surface which is in use exposed to fluid pressure.
  • the thicker region or regions of the gasket is/are urged into a decreasing smaller recess volume by the fluid, to aid sealing.
  • the recess in the edge of the first and/or second member may be configured generally to correspond to the cross-sectional profile of the gasket.
  • the gasket includes in the main, a length of an elastic material such as rubber although if desired in addition to the elastic material of the gasket, hydrophillic sealing material may be provided between the edges of the first and second members, again to aid sealing.
  • an elastic material such as rubber although if desired in addition to the elastic material of the gasket, hydrophillic sealing material may be provided between the edges of the first and second members, again to aid sealing.
  • the hydrophillic material is separate from the gasket but preferably is attached to the gasket or integral with the gasket.
  • the hydrophillic material may be co-extruded with the gasket.
  • the recess in the edge of the first and/or second member may be particularly configured so as to accommodate the hydrophillic material therein.
  • the gasket may have at least one internal chamber.
  • the gasket in cross-section, may include a first major surface which extends generally parallel to the edges of the first and second members, a second major surface which is inclined to the edges of the first and second members, and side faces between the first and second major surfaces.
  • first major surface which extends generally parallel to the edges of the first and second members
  • second major surface which is inclined to the edges of the first and second members
  • side faces between the first and second major surfaces may include a pair of inclined face parts which may meet on a line towards the adjacent side surfaces with at least one of the face parts inclined away from the line.
  • the line where the pair of face parts meet may be located within the recess of the edge of the first or second member.
  • the gasket may be of a symmetrical or non-symmetrical cross-sectional configuration.
  • the gasket may include an integral anchor means which includes a formation which in use, extends inwardly of the respective member away from the recess.
  • the first and/or second member is made of a settable material such as concrete
  • the formation may be embedded in the first or second member before the settable material sets.
  • a gasket may integrally be provided with the first and/or second member.
  • the formation may include a plurality of laterally existing tangs.
  • each of the first and second edges of the first and second members has a recess and a gasket, so that as the first and second members are brought together the two gaskets engage each other to provide a seal between the two edges.
  • Each of the first and second members may be generally rectangular in side view, having two pairs of opposed edges between the intrados and extrados side surfaces.
  • a recess is provided in all four edges of at least one of the members, each recess receiving a gasket.
  • a tunnel lining or pipeline including an edge seal assembly according to the first aspect of the invention.
  • an edge seal assembly 10 includes a first member 11 which has intrados 12 and extrados 13 side surfaces, and a first edge 15 between the side surfaces, and a second member 18 having an intrados 19 and extrados 20 side surfaces and a second edge 21 between the side surfaces 19 and 20, the first and second edges 15 and 21 facing one another in use.
  • the first and second members 11 and 18 are in this example, tunnel lining members.
  • the tunnel extends generally in the direction of arrow A such that the members 11 and 18 each have a curvature extending away from their respective edges 15 and 21, the edges 15 and 21 being generally planar and linear.
  • each of the first and second members 11, 18 each includes a recess 24 which is adapted to receive a gasket 25 such that as the first 11 and second 18 members are brought together the gaskets 25 which project from the respective recesses 24, engage to form a seal between the adjacent edges 15 and 21. It will be appreciated that a substantial compressive force may be applied to the gaskets 25 so that they provide a seal.
  • the tunnel lining members 11 and 18 form a barrier to fluid from the extrados side surfaces 13 and 20 entering the tunnel, and the edge seal between the first and second members 11 and 18 thus needs to be substantially fluid tight.
  • the fluid pressure to which the extrados side surfaces 13 and 20 exposed, can be substantial.
  • each member 11,18 the recess 24 and the gasket 25 is of a non-symmetrical but generally corresponding configuration and the gaskets 25 are oppositely handed.
  • the general thickness of each gasket 25 decreases from a thicker region 26 to a thinner region 27, the thicker regions 26 being located more closely to the extrados side surfaces 13 and 20 than the intrados side surfaces 12 and 19 of the first and second members 11 and 18.
  • the recesses 24 in the edges 15, 21 of the first and second members 11,18 are correspondingly configured, decreasing in depth from a deeper region 28 to a shallower region 29.
  • the thicker regions 26 of the gaskets 25 will be urged sideways in their respective recesses 24 towards the lower volume shallower recess regions 29.
  • increasing fluid pressure merely improves the sealing effectiveness of the gaskets 25.
  • each gasket 25 includes a generally elongate length of preferably elastic material, having, in this example three, internal chambers 30 which aid deformation of the gasket 25 particularly as compressive forces are exerted (in the directions of the arrows B and C in Figure 2), as the first and second members 11 and 12 are brought together, as well as in response to fluid pressure at the extrados side surfaces 13 and 20.
  • the gaskets 25 each have a first major surface 32 which extends generally parallel to the side edges 15 and 21 of the first and second members 11 and 18, and which engage when the members 11,18 are brought together edge to edge. Further, each gasket 25 has a second major surface 33 which is inclined to the side edges 15 and 21 of the first and second members 11 and 18, and to the first major surface 32, and each gasket 25 includes side faces 34 and 35 between the first and second major surfaces 32 and 33. Each of the side faces 34 and 35 has a pair of inclined face parts 36 and 37, and 38 and 39. The side faces 36 and 37 and 38 and 39 meet on a line 40 and the face parts 36 and 37 and 38,39 incline away from the line 40.
  • the second major surfaces 33 of the gaskets 25 include a pair of recesses 43.
  • alternative sealing material may be provided between the edges 15 and 21 of the members 11 and 12.
  • the gasket 25 is co-extruded with such additional material 45 and 46, the material 45, 46 being hydrophillic material which swells when subjected to liquid, particularly water.
  • the hydrophillic material 45 and 46 is integral with the remainder of the generally elastic rubber gasket 25, although hydrophillic material 45, 46 could be provided separately in addition to the gasket 25 in an alternative arrangement.
  • the recesses 24 in the edges 15,21 of the first and second members 11, 18 are configured in any event, to accommodate such hydrophillic material 45 and 46 where provided, and where necessary.
  • the edge 21 of the second member 12 may have a recess 24 to receive a gasket 25, such that the first major surface 32 may simply engage a plain edge 15 of the member 11, or the edge 15 of member 11 may have a recess but no gasket, to receive the first major surface 32 of a gasket 25 in a recess 24 of the edge 21 of the member 18.
  • the assemblies 10 so far described are particularly suitable to an application where there is fluid pressure on only the extrados 13, 20 side surfaces of the members 11 and 12, and the object is to prevent such fluid entering the inside of a tunnel.
  • fluid pressure may be exerted on the intrados side surfaces 12 and 19 of the members 11 and 18, the object being to prevent such fluid escaping from the pipeline to the extrados side surfaces 13 and 20.
  • the recess 24 or recesses 24 and gasket or gaskets 25 would need to be of an opposite configuration such that the thicker region or regions 26 of the gasket or gaskets 25 would need to be accommodated closer to the intrados side surfaces 12 and 19 than the thinner region 27 which would be located closer to the extrados side surfaces 13 and 20.
  • first and second members 11 and 18 may serve to separate fluids on the extrados 13 and 20 side surfaces and the intrados 12 and 19 side surfaces of the members 11 and 18.
  • fluid pressure may be exerted in both opposite directions on the gasket or gaskets 25 generally normal to the directions of arrows B and C shown in Figure 2 and Figure 4.
  • each of a pair of gaskets 25 decreases from a thicker region 26 closer adjacent to the extrados 13 and 20 side surfaces towards a thinner region 27 located closer adjacent to the intrados 12 and 19 side surfaces, but the thicknesses of the gaskets 25 then again increase towards a further thicker region 26' which is closer adjacent to the intrados side surfaces 12 and 19 compared to the thinner region 27 which is now located closer to the extrados side surfaces 13 and 20.
  • the thinner regions 27 each provide a waist in the respective gasket 25.
  • Recesses 24 and 24' are provided in each of the edges 15 and 21 of the first and second members 11 and 12 to accommodate the gaskets 25.
  • each includes a pair of inclined face parts 34, 34a which meet at a line 40,' 40'' and the face parts extend away from the lines 40', 40''.
  • the thicker region 26 of the gasket 25 shown in Figure 4 When exposed to fluid pressure on the extrados surfaces 13 and 20, the thicker region 26 of the gasket 25 shown in Figure 4, is urged towards the lower volume thinner regions of the recess 24, and when subjected to fluid pressure on the intrados side surfaces 12 and 19, the thicker region 26' is urged towards the thinner lower volume region 27 so that sealing is improved whether the fluid pressure is applied to the extrados 13, 20 and/or intrados 12 and 19 side surfaces.
  • gaskets 25 shown in Figure 4 could include or be attached to or be integral with elements of another sealing material such as hydrophillic material located between the edges 15 and 21 of the first and second members 11 and 18.
  • gasket or gaskets 25 and corresponding recess or recesses 24 may be changed to suit different applications although in each case, there will be a thicker gasket region closer adjacent to one of the side surfaces which may be subjected to a fluid pressure greater than the pressure at an opposite side surface of the assembly.
  • the gaskets 25 each includes an integral anchor means including a formation A which extends away from the recess 24 into the body of the respective member 11,18, and each formation A has a plurality of tangs T.
  • the members 11,18 are made in a settable material such as concrete, and the gaskets 25 are arranged in the mould during casting of the concrete to form the members 11,18, such that the formations A become embedded in the concrete as the concrete sets.
  • the gaskets 25 are attached to the members 11, 18 so that in forming the assembly 10, positioning of the gaskets 25 relative to the recesses 24, is not required.
  • the gaskets 25 will be received already in the recesses 24 as the first 11 and second 18 members are brought together edge 15 to edge 21.
  • the formation A of the gasket 25 for member 11 has a pair of relatively inclined features F1 and F2, each of which terminates in a generally round tang T.
  • the formation A of the gasket 25 for member 18 is of a conical configuration, with laterally outwardly extending Tangs T along the cone axis.
  • a gasket 25 may be attached to one of the members 11,18 only which has a recess 24 during casting of member 11,18 in concrete, in a mould.
  • anchor means may be used in conjunction with hydrophillic materials such as is described with reference to figure 2.
  • each of the first 11 and second 18 members is generally rectangular in side view, i.e. from either intrados 12/19 or extrados 13/20 surfaces, having two pairs of edges 15,21, and 15',21' (seen in figure 1).
  • edges 15,21 are generally linear, whereas edges 15',21' will be curved, following the curve of the intrados 12,19 and extrados 13,20 surfaces.
  • Gaskets 25 as described above may be provided in recesses 24 in all four edges of the members 11,18 to provide edge seals not only between edges 15,21 which extend axially of the tunnel lining or pipeline, but circumferentially too.
