Definitions
- the invention relates to an expansion profile for the expansion of Tunnels and mining routes with circular or partially circular driveway cross section, which expansion a has a support shell on the mountain side and a tunnel tube side or support tube made of concrete on the track tube side may have, wherein the mountain-side support shell from Mountains, according to the curvature of the ramp cross-section curved full steel profiles and shotcrete, in which the full steel profiles are embedded is, the full steel profiles arm flanges and a web flange exhibit.
- the bar grids consist of two arranged on the tunnel tube or track side, parallel as well as according to the circular or part-circular Arc guided round steel bars and one
- the third round steel bar on the mountain side is one of the the other two is guided in parallel and with these in cross section an isosceles triangle spans.
- the round steel bars are through crossbars and Diagonal bars connected in welded construction. Is working one with such bar lattice arches, these can be used as Reinforcement in the shotcrete layer on the mountain side to get integrated.
- the area moment of inertia as well as the Stability of the wire mesh arches are in and of themselves however, with the same use of materials, less than for the Full steel profiles. The manufacture of the wire mesh arches is consuming.
- the invention is based on the technical problem an expansion of the structure described above To improve shape stability and stability, and with as little material and effort as possible Regarding the manufacture of the steel profiles.
- the invention teaches to solve this technical problem an expansion profile for the expansion of tunnels and mining Stretch with circular or part circular Driveway cross-section, which expansion a mountain side Carrier shell and a tunnel tube side or can have a supporting shell made of concrete on the track tube side, the mountain-side support shell from the mountains adjacent, according to the curvature of the ramp cross-section curved full steel profiles and shotcrete, in which the full steel profiles are embedded is, the full steel profiles arm flanges and a web flange have, the solid steel profiles a Y-shaped Have profile cross-section, the Y-web flange lies against the mountains and the Y-arm flanges Point tunnel tube or to the route tube, the full steel profiles on the Y-flange and on the Y-arm flange have longitudinal ridges on the edge and with the Y-flange and the Y-arm flange between them span an angle of 120 ° to 130 °.
- the Y-flange and the Y arm flanges preferably an angle of between them Span 120 °.
- the invention teaches an expansion profile for the expansion of Tunnels and mining routes with circular or partially circular driveway cross section, which expansion a has a support shell on the mountain side and a tunnel tube side or support tube made of concrete on the track tube side may have, wherein the mountain-side support shell from the mountains, according to the curvature of the ramp cross-section curved full steel profiles and shotcrete, in which the full steel profiles are embedded is, the full steel profiles arm flanges and a web flange have, the solid steel profiles a Y-shaped Have profile cross-section, the Y-web flange lies against the mountains and the Y-arm flanges Point tunnel tube or to the route tube, the full steel profiles on the Y-flange and on the Y-arm flange have longitudinal ridges on the edge and with the Y-arm flanges between them at an angle of 70 ° up to 90 ° and an angle of 135 ° against the Y-flange have up to 145 °.
- the longitudinal ones are expedient Beads with a circular cross-section.
- the Y-arm flanges an angle of preferably 80 ° between them and an angle of preferably against the Y-flange Have 140 °.
- the Bead of the Y-flange flange a circular cross-section on.
- the invention is based on the finding that full steel profiles with Y-shaped profile cross-section for the stresses in the described expansion for tunnels or Lines have particularly favorable moments of inertia, both in terms of dimensional stability as well as in terms of stability. Furthermore the shotcrete can be placed without spray shadow be what the shortcomings described above when using avoids full steel profiles of different cross-section.
- the full steel profiles used according to the invention also Y-shaped cross section lead to a very good bond Full steel profile / shotcrete. This is especially true for the Embodiment with ridges running lengthwise on the edge.
- the stability and the Composite can also be influenced by the angle between the Y-flange and the Y-arm flange is realized.
- the embodiments can can be easily manufactured using rolling technology.
- the expansion 1 shown in the figures is for tunnels and mining routes with circular or semi-circular Ramp cross section determined.
- the expansion 1 has a mountain-side support shell 2, which is shown in FIG. 1 was drawn.
- a tunnel tube side or support tube made of concrete on the track tube side be what was not drawn.
- the mountain side Carrier shell 2 is made from the mountains 3, after Provided the curvature of the drive-on cross-section is curved Solid steel profiles 4 and shotcrete 5 built.
- the solid steel profiles 4 are Y-shaped Have profile cross-section, the Y-flange 6 on the mountains 3 rests and its Y-arm flanges 7 to the tunnel tube or stretch tube 8 have.
- Solid steel profiles 4 on the Y-flange 6 and on the Y-arm flanges 7 have longitudinally extending beads 9 on the edge. In the exemplary embodiment, they have a circular shape Cross-section.
- the Y-arm flanges 7 span an angle between them 90 ° and against the web flange 6 each an angle of 135 ° on. But you could also use other angular positions Realize Y-flange 6.
- Fig. 3 makes clear how an expansion sheet from several Partial sheets 10, 11 made of solid steel profiles 4 with Y-shaped Profile cross section could be built.
- the beads 9 formations 12 which serve the bond between the solid steel profiles 4 and Shotcrete 5 to improve.
- the partial sheets 10, 11 connected with tabs 13 are.
- the tab connection can also be flexible can be set up by means of dash-dotted lines indicated elongated holes 14, screwed into the clamping screws 15 are whose voltage is the insertion resistance certainly.
