Definitions

  • the present invention relates to a method of constructing a tunneling traffic tunnel in which tubbing members are assembled in a machined cavity bore to form a closed tunnel wall, and the space between the inner wall of the cavity bore and the outer walls of the tubbing members is filled with bead gravel.
  • the traffic tunnel in a machine-generated cavity bore in a single-shell construction is created by means of tubbing components or bivalve, is created with an additional Ortbetoninneschale to obtain a closed lining.
  • the space between the inner wall of the cavity bore and the outer walls of the tubbing components, also referred to below as the annular gap, is filled up with pearl gravel.
  • silica resin is injected as a cement-free annular gap filling under pressure in the intermediate space to fill the gap, seal and embed the tubbing components. This pressing process is carried out with an overpressure depending on the static requirements.
  • the sealing effect of the cured Silicate resin prevents at the same time movements and reactions of atmospheres.
  • multi-grain perlkies preferably double-grain perlkies.
  • the consumption of the silicate resin can thereby be significantly reduced.
  • the injection of silicate resin is carried out under such high pressure that loosening zones and a naturally occurring lumpiness / porosity of the surrounding rock are filled and sealed.
  • this injection of silicate resin under high pressure occurs at least in the region of junctions between geologically problematic environments that react with water and geologically unproblematic areas where water may occur in the vicinity of the cavity bore to provide a barrier to water loneliness along the traffic vegetation tunnel geologically unproblematic in the geologically problematic environment of the cavity bore to produce.
  • modified water-reactive silicate resin is used for injection into the interstitial space filled with pearl gravel, which utilizes existing spent water from the construction phase for setting and thus consumes.
  • modified non-water-reactive silica resin is used for injection into the pebble-filled interstice which does not consume existing process water from the construction phase, but pushes it in front of it and drains it through targeted outlets.
  • swellable silica resin is injected into the pebble-filled space having a swelling degree of 0.5 to 1% to stabilize simultaneously loosened environmental areas to a greater extent.
  • multigrain perlites allows for a denser filling of the interstice than single grain perlite, requiring less silica resin.
  • double-grain perlites is preferred, e.g. with a grain size from the range 2 to 4 mm and a grain size from the range 6 to 8 mm, for example, two grain sizes of 3 mm and 7 mm.
  • multigrain bead gravel with too many grain sizes or even with a uniform grain size distribution, for example in the range of 2 to 8 mm is not preferred, since then there is a dense packing of the multigrain Perlkieses that remains only little volume for the silica resin ; thus its function would be limited as a sealing material.
  • Fig. 1 gives an overview of a built according to a method traffic tunnel according to the invention.
  • a cavity bore has been made by a tunnel boring machine.
  • precast concrete Tübbingbaumaschine
  • Seals for example of ethylene-propylene-diene rubber (EPDM)
  • EPDM ethylene-propylene-diene rubber
  • Fig. 2 shows a detailed view of a cross section through a traffic tunnel in an intermediate stage of the construction method according to the invention.
  • the remaining annular gap is filled with pearl gravel, preferably with multigrain perlkies, in this embodiment with double-grain perlkies, for example with particle sizes of 2 mm and 8 mm, through the penetrations in the tubbing components ,
  • Fig. 3 shows the same detail view of the section through the traffic tunnel as in Fig. 2 after a further process step, namely the injection of silicate resin through the penetrations in the tubbing components.
  • the silica resin is injected under pressure so that it fills any remaining voids between the grains in the grain filling of the annular gap.
  • the silicate resin is injected under such high pressure that backfilling zones or a naturally present lumpiness / porosity of the surrounding rock are filled and sealed. This is in Fig. 3 represented by the fact that the black silicate resin has also penetrated into the surrounding mountains along some lines outside the annular gap. This results in a compensation of the surrounding mountains.
  • Such injection of silicate resin under high pressure is particularly useful in the area of transitions between geologically problematic environments that react with water and geologically unproblematic areas where water may occur in the vicinity of the cavity bore to provide a barrier to water longitudinality in the longitudinal direction of the To produce traffic tunnel from the geologically unproblematic in the geologically problematic environment of the cavity bore.
  • Such barriers prevent the traffic tunnel itself from contributing to the aqueduct along its longitudinal direction into the geologically problematic area of water-reactive constituents.
  • Pressing in silicone resin with increased pressure can for example take place at a pressure of 10 to 15 bar.
  • the penetrations in the tubbing members, through which the beads and the silica resin are introduced into the annular gap are shown for the sake of simplicity of illustration with a constant diameter.
  • conical penetrations are preferred whose diameters differ from the inner wall of the tubbing component to the outer wall increases. Due to the conical shape of the penetration remains sealed after filling with the silica resin after curing.
  • silicate resin for example, a 2-component, non-foaming, slightly-flexibilized silicate-based injection resin can be used for injection of water-bearing cracks as well as soil and rock solidification.
  • the silicate resin is prepared by mixing two components, these components A and B comprising a waterglass component A and an isocyanate-containing component B. After the homogeneous mixing of the two components, a viscous emulsion is formed, which does not take up any further water from the injection area, but pushes it in front of it due to the high density.
  • the preferred silicate resin has the following technical data:
  • the two components are conveyed in a mixing ratio of 1: 1 (by volume) using two-component injection pumps directly from the containers and homogeneously mixed by a static mixer.
  • the initially liquid mixture quickly reaches a no longer flowable state and then cures quickly without foaming.
