Definitions

  • the present invention relates to an improved "cast-in" tunnel gasket and a method of joining such a tunnel gasket.
  • Elastomeric (rubber) gaskets are used to seal segmentally formed tunnels; for example, against water ingress.
  • the rubber gaskets are fitted between concrete tunnel segments.
  • rubber tunnel gaskets were fitted into grooves pre-formed in the tunnel segments and secured with adhesive.
  • An example of an existing cast-in tunnel gasket includes that disclosed in patent publication WO2013189491 (Datwyler), wherein a moulded product is produced in a shutter assembly. It is known to provide such anchored/"cast-in” tunnel seals as an alternative to inserting a seal in a pre-cast groove in the concrete using a contact adhesive.
  • a “cast-in” tunnel segment gasket (TSG) has been found to offer advantages in reliability and eliminates the cost and inconvenience of using adhesives.
  • TSG tunnel segment gasket
  • “cast-in” tunnel segment gaskets are manufactured by encasing the segment gasket in concrete during the casting of the segments themselves. It is also known that it is advantageous to provide a gasket profile that allows for the significant forces that the concrete tunnel segments are to be placed under.
  • the tunnel segment gasket comprises profiled geometries according to the expected deformation of the gasket under compression; for example including one or more longitudinal channels running therethrough and/or having "anchored” profiles with legs protruding therefrom. It is known that a cast-in tunnel gasket "collapses" into the groove into which it has formed during use, to close the gap between adjacent concrete tunnel segments.
  • a solid corner join results from "shooting" rubber in at the corner joint, often termed a “shot-joint", which then travels along the longitudinal channels in the adjoining gaskets.
  • a solid, filled corner joint does not allow for any compression or movement of the joint; for example if the TSGs are not aligned perfectly or if there is ground movement after installation.
  • existing solid corner TSG joints lead to excessive load building up at the corners, which will eventually lead the concrete segments attached thereto to crack.
  • the gaskets will be not be securely held and leaks are very likely to occur.
  • the cross-section or profile of the gasket is designed to take the strain of the load applied by the adjoining tunnel segments; that is, to minimise the closure forces exerted on the tunnel segments whilst securely sealing the tunnel.
  • the invention provides a tunnel segment gasket comprising a shaped profile having at least two anchoring legs for casting in to a tunnel segment; a plurality of longitudinally extending bores; a shot film joint and a strengthening element at the base of the gasket.
  • base of the gasket refers to the face of the gasket between the two anchoring legs, which is external to the shot film joint.
  • the strengthening element is shaped and positioned to increase the strength of the tunnel segment gasket at the joint.
  • the strengthening element is a rhombus shape having a centre line parallel to the shot film joint.
  • the strengthening element is integral with the shot film joint.
  • the shot film joint is concealed within the tunnel segment gasket and the strengthening element is exposed at the base of the gasket.
  • the configuration of the present invention provides much improved joint security for tunnel segment gaskets.
  • the strengthening element acts, in use, as a "keying element” and protrudes from the shot film joint at the base of the main body of the shaped profile.
  • the strengthening element of the profile does not affect the load characteristics of the gasket under compression.
  • the strengthening element/"keying element” does not hinder the closure performance of the tunnel segments nor does it affect the load compressing the gasket, but provides a remarkably secure joint. It has been found that the security of the joint is remarkably improved and the risk of the gasket pulling apart at the joint and the joint failing is much reduced.
  • the tunnel segment gasket further comprises at least one curved protrusion on its base.
  • the present invention minimises load build up when joining gaskets at a corner, i.e. so that the joint has substantially the same load characteristics at the corner as the remainder of the gasket.
  • the present invention optionally provides an improved gasket profile whereby one or more curved protrusions on the base of the gasket provide a greater surface area over which a gasket joint can be formed. It has been found that by increasing the surface area of the gasket at the joint, the gasket is less likely to tear or split. Thus, a secure seal for segmentally lined tunnels can be formed whilst using a reduced amount of rubber at the joint.
  • the volume of rubber at the joint is minimised to ensure that the gasket can take the strain of the adjoining tunnel segments and avoid the generation of excess force at the joint.
  • the profile of the TSG of the present invention provides the required energy within the seal and generates a secure seal when the segments have been assembled; for example against water ingress, or for retention in tunnels used for transport of storage.
  • the cross-section of the or each longitudinally extending bore is circular.
  • the TSG performs better when a load is applied, i.e. when multiple tunnel segment gaskets are joined.
  • the relative movement of the TSG under load will be substantially the same regardless of the direction in which the load is acting on the or each longitudinally extending bore.
  • the TSG is better able to withstand the load exerted on it when it collapses into the segment groove in which it is held, when tunnel segments are joined. This ensures that the TSG does not collapse without effectively sealing the segments and minimises the closure forces exerted on the tunnel segments.
  • the cross-section of the or each longitudinally extending bore is semi-circular.
  • the plurality of longitudinally extending bores comprises one or more, preferably a plurality of bores having a circular cross-section and one or more, preferably a plurality of bores having a semi-circular cross- section.
  • the tunnel segment gasket comprises at least two curved protrusions on its base.
  • Having two curved protrusions on the base of the TSG provides an increased surface area over which a gasket joint can be formed, whilst ensuring that the gasket is less likely to tear or split.
  • the or each curved protrusion is positioned between the two anchoring legs.
  • the tunnel segment gasket further comprises at least two shaped transverse protrusions. Having shaped transverse protrusions or shoulders allows for secure casting of the TSG in a concrete tunnel segment, wherein the shoulders lay substantially parallel to the plane of the face of the concrete tunnel segment, in use.
  • the tunnel segment gasket has a width of between about 20mm and about 50mm; preferably, between about 28mm and about 45mm .
  • the invention provides a method of forming a tunnel segment gasket joint comprising the steps of:
  • the method comprises providing a thin elastomeric film between the angled ends of the first and second tunnel segment to form a joint and a strengthening element integral with the joint.
  • the method comprises forming a joint and an integral strengthening element wherein the strengthening element is exposed at the base of the gasket.
  • the present invention provides a much improved spliced joint for a tunnel segment gasket and also addresses a previously identified problem whereby the diagonal cutting of a profiled TSG was not possible.
  • a first and second cutting guide By using a first and second cutting guide, movement of the shaped flexible profile of the TSG away from the cutting blade is prevented to significantly improve the accuracy of the required diagonal cut at the joint-facing ends of the TSG.
  • the method of the present invention offers an improvement in ensuring that the angle of the TSG can be carefully selected according to the tunnel segments with which the TSGs will be used and also ensures that the TSG is held securely prior and during cutting.
  • the method of the present invention avoids elastomeric material travelling along the channels of grooves in the gasket.
  • the method of the present invention ensures that the load generated at the joint is evenly distributed across the corner; the TSG adjacent thereto and along the reminder of the gasket; that is, no excessive load is created. By carefully maintaining the profile of the TSG this ensures that any point stresses will be avoided, which could lead to splitting of the gasket and crack propagation, so that no cracking of the concrete segments will result over time.
  • the elastomeric film is a rubber film .
  • the thin elastomeric film has a thickness of between about 0.2mm and about 2mm .
  • the thin elastomeric or rubber film is provided by placing the film between the angled ends of the first and second tunnel gasket to form a joint; more preferably, the thin elastomeric or rubber film is provided by injecting or "shooting" the elastomeric or rubber film between the angled ends of the first and second tunnel gasket to form a joint; optionally, the thin elastomeric or rubber film is provided by placing a rubber film between the mating faces to be joined.
  • the method of forming a tunnel segment gasket joint further comprises the step of clamping at least one end of both the first and second tunnel segment gaskets.
