Definitions

  • the invention relates to an expansion profile for the expansion of tunnels and mining routes with a circular or teli Vietnamese driveway cross-section, which expansion has a mountain-side support shell and can have a tunnel tube-side or track-tube-side support shell made of concrete, the mountain-side support shell made of adjacent to the mountains, according to the curvature of the drive-on cross-section, curved solid steel profiles and shotcrete, in which the solid steel profiles are embedded, is constructed, the solid steel profiles having arm flanges and a web flange.
  • the solid steel profiles are I-profiles, U-profiles or bell profiles with a corresponding moment of inertia, which is advantageous for the intended use, also with regard to the orientation of the solid steel profiles in the expansion. They lie on the mountains with a relatively wide profile back. This results in a so-called spray shadow for the production of the mountain-side support shell using shotcrete in the area of the full steel profiles, in which the mountains are not or only partially covered by the shotcrete. The functional fusion of the solid steel profiles with the shotcrete is not very pronounced. This affects the structural strength and the stability of the mountain-side support shell.
  • the bar grid arches consist of two round steel bars arranged on the tunnel tube or track side, guided in parallel and in accordance with the circular or semi-circular arc, and a third round steel bar on the mountain side, which is guided parallel to the other two and spans an isosceles triangle with these in the cross section of the bar grid.
  • the round steel bars are connected by cross bars and diagonal bars in welded construction. If you work with such bars, they can be integrated as reinforcement in the mountain-side shotcrete layer.
  • the area moment of inertia and the stability of the bar lattice arches in and of themselves, however, are lower than with solid steel profiles when using the same material.
  • the manufacture of the bar grille arches is complex.
  • the invention is based on the technical problem of improving the structural strength and stability when the structure described at the outset is expanded, with the least possible use of material and effort in relation to the production of the steel profiles.
  • the invention teaches, starting from the expansion described above for tunnels and mining routes, that the solid steel profiles have a Y-shaped profile cross-section, the Y-web flange rests on the mountains and the Y-arm flanges to the tunnel tube or to the route tube indicate that the solid steel profiles on the Y-web flanges and on the Y-arm flanges have longitudinally running beads and that the Y-web flange and the Y-arm flanges span an angle of approximately 120 ° between them.
  • the Y-web flange and the Y-arm flanges can span between them, for example, an angle of 110 ° to 130 °, preferably 120 °.
  • the solid steel profiles have a Y-shaped profile cross-section, the Y-web flange abutting the mountain and the Y-arm flanges facing the tunnel tube or the route tube, that the full-steel profiles on the Y-web flanges and have longitudinally running beads on the Y-arm flanges and that the Y-arm flanges have an angle of approximately 90 ° between them and an angle of approximately 135 ° to the Y-flange.
  • the longitudinal beads have a circular cross-section.
  • the Y-arm flanges can have an angle between them of 70 ° to 90 °, preferably 80 ° and against the Y-web flange an angle of 135 ° to 145 °, preferably 140 °.
  • the bead of the Y-web flange has a circular cross section.
  • the invention is based on the finding that solid steel profiles with a Y-shaped profile cross-section have particularly favorable moments of inertia for the stresses in the described expansion for tunnels or routes, both in terms of the structural strength and in terms of stability.
  • the shotcrete can be applied without spray shadow, which avoids the shortcomings described above when using solid steel profiles of different cross-section.
  • the full steel profiles with a Y-shaped cross section used according to the invention also lead to a very good composite full steel profile / shotcrete. This applies in particular to the embodiment with beads running longitudinally along the edge.
  • the area moment of inertia, the stability and the bond can also be influenced by the angle which is realized between the Y-web flange and the Y-arm flanges.
  • the embodiments can be produced in a simple manner using rolling technology.
  • the expansion 1 shown in the figures is for tunnels and mining routes with circular or part-circular Ramp cross section determined.
  • the extension 1 has a mountain-side support shell 2, which was drawn in Fig. 1.
  • a supporting shell made of concrete on the side of the tunnel tube or on the section tube could be arranged, which was not drawn.
  • the mountain-side support shell 2 is constructed from solid steel profiles 4 and shotcrete 5 which rest against the mountains 3 and are curved in accordance with the curvature of the drive-on cross section.
  • the solid steel profiles 4 have a Y-shaped profile cross section, the Y web flange 6 of which rests on the rock 3 and the Y arm flanges 7 point towards the tunnel tube or section tube 8.
  • the solid steel profiles 4 have longitudinal beads 9 on the Y-flange 6 and on the Y-arm flanges 7 on the edge. In the exemplary embodiment, they have a circular cross section.
  • the Y-arm flanges 7 span between them an angle of 90 ° and against the web flange 6 each an angle of 135 °. But you could also realize other angular positions of the Y-flange 6.
