Definitions

  • the present invention relates to a method for making a tunnel by means of prefabricated concrete elements, joined together on site by concreting.
  • the tunnels are produced either by pouring successive tunnel sections in place, or by aligning prefabricated tunnel sections.
  • the tunneling process which consists of aligning prefabricated tunnel sections allows the length of the site to be reduced.
  • the prefabricated sections are placed, the backfilling and finishing work can be carried out.
  • the process according to the present invention in fact calls upon a certain number of standardized prefabricated elements, of relatively reduced weight (approximately 10 tonnes), the handling of which requires only more mobile lifting devices, of the type commonly used on most Construction sites.
  • These lifting devices can be automobile cranes, which do not need to be mounted on rails.
  • the use of standardized prefabricated elements makes it possible for the process of the invention to make tunnels of small section and tunnels of larger section, for example for large gauge metro, underground railway, etc., by juxtaposing a greater or lesser number of these standardized elements.
  • the method according to the invention makes it possible to vary the section of the tunnels, which can thus pass from a minimum section (for a single tunnel section of line) to a maximum section (sections of tunnel comprising stations, with landing platforms, waiting rooms, etc.) passing through intermediate sections.
  • the subject of the present invention is a method for producing a tunnel by means of prefabricated concrete elements, which are joined together by concreting, after placement.
  • the successive phases of realization of the tunnel are executed in order along the site, from the advancement front where the earthworks and the front excavation of the excavation are done to the area where the backfilling and the covering of the completed tunnel are done.
  • the vertical elements partially constituting the side walls of the tunnel are oblong shells of reinforced concrete having a cylindrical arch whose generator is parallel to the major axis of the shells; these shells are closed at each of their ends by a base in half line, perpendicular to their major axis.
  • These shells are arranged in such a way that their concavity is directed towards the interior of the tunnel, and that their vault is directed towards the walls of the trench.
  • the shells have two flat and parallel longitudinal sides extending the arch on each side thereof.
  • An advantageous embodiment of these elements has, on the outside of the vault, a substantially planar rear face which is connected perpendicular to the lateral faces of the element, which are also substantially planar.
  • the shells have on the outer faces of the longitudinal sides two grooves parallel to the major axis of the shells, capable of receiving the lateral edges of the two formwork plates.
  • the grooves located near the free edge of the plane longitudinal sides of the hulls, and therefore located on the inside of the tunnel are widened at their upper part, so as to constitute close to the level which the edge will occupy. upper side of the plate in place, shoulders on which the end of a lintel sits.
  • the reinforced concrete footings as well as the connecting footings ensuring continuity between them are provided, on their upper bearing face, with a rebate parallel to the axis of the tunnel and directed towards the interior of the tunnel.
  • the assembly of a beam, of the two reinforced concrete columns which support each of the ends of this beam and the footings supporting each of these reinforced concrete columns, forms a gantry capable of taking up the vertical pressures exerted by the earth and the roads. higher, as well as the horizontal earth pressure.
  • the method according to the invention has a number of advantages.
  • the arch shape of the hulls preferably used offers the advantage of taking up the horizontal loads of pushing the earth after backfilling behind the side walls of the tunnel with relatively thin partitions and not requiring additional reinforcements.
  • the hulls can be prefabricated in molds specially made for this purpose but, for small series, it is more economical to use molds of standardized shape, generally of rectangular section.
  • the face turned towards the outside of the tunnel is practically planar and is connected perpendicular to the lateral faces, which are also practically planar.
  • Such an embodiment coincides with the form of standard molds.
  • the number of prefabricated elements used being reduced (indeed, it mainly comprises only the footings, vertical elements forming the vertical walls, lintels, upper beams and slabs), the installation of these is a series of repeated operations, which promotes speed of execution.
  • the construction of a heavy-type metro tunnel can progress at the rate of approximately 3 running meters per day.
  • the disturbance caused to residents is therefore minimal, thanks to the speed of execution and therefore thanks to the mobility of the site.
  • the site is all the more mobile as the site facilities are reduced, thanks in particular to the manufacture of a maximum of elements off the site (prefabrication in the factory).
  • the process according to the invention also lends itself to the construction of tunnels in an aquiferous environment, thanks to the arrangement of the hulls, which will thus serve as a passage for sheets as will be described below. It is indeed important in the case of aquifers, not to oppose the movements of groundwater.
  • the process allows to marry the various unevennesses of the ground as well as the changes of direction imposed by the layout, while using the majority of the prefabricated elements above.
  • the method also lends itself to the production of tunnels of various widths, for example, narrow in a straight line, wide at the station, passing through intermediate sections connecting the narrow sections and the wide sections. As will be described below, these different widths are produced with the available prefabricated elements already described.
  • the process according to the invention makes it possible to combine the structural work and the finishing touches; in particular inside the stations one can take advantage of the shape of the hulls.
  • the dimensions of these shells can vary between relatively wide limits, but according to a particular and advantageous embodiment of the invention, the width of these shells is between 2 and 3 meters.
  • the walls of the stations present species of niches, which can be fitted out, as required, for example, by installing telephone booths, automatic distributors, benches, etc.
  • the benches can advantageously be continuous or interrupted ribs cast in the mass during the manufacture in the factory of the shells.
  • the shells forming the walls of the tunnel between the stations can be arranged to receive electrical devices such as junction boxes, lighting, signaling devices, etc.
  • the particular configuration of the walls can also be used advantageously acoustically. Indeed, sounds are picked up by the surface of the walls, which considerably lowers the acoustic level and thus improves the comfort of tunnel users, especially passengers waiting at stations.
  • prefabricated reinforced concrete footings 1 of generally rectangular shape, the upper face 2 of which has a rebate 3, are deposited on the bottom of the trench, leaving a space between the successive soles 1.
  • Each sole is arranged so as to be perpendicular to the vertical walls of the tunnel to be constructed, so that the rebate 3 is directed towards the interior of the tunnel.
  • each connecting flange 4 also has on its upper face 6 a rebate 7 connecting the rebates 3 of two successive flanges 1.
  • Oblong reinforced concrete shells 8 having a cylindrical vault 9 whose generatrix is parallel to their major axis, two plane longitudinal sides 10 extending this vault 9 on each side, and closed by a base, 11 in half-moon at each of their ends, are arranged on each continuous base 5, so as to provide an interval between successive shells 8, and so that their vault 9 is directed towards the wall of the trench and, consequently, that their concavity is directed towards the interior of the tunnel.
  • the shells 8 are placed in such a way that each shell 8 is supported both on two successive flanges 1 and therefore that.
  • the interval between two successive shells is located in line with a sole 1.
  • the shells 8 are placed by means of a positioning mannequin carrying a pair of shells 8, so as to simultaneously place two shells 8 on each side of the tunnel, one in line with the other.
  • the interval between two successive shells 8 is closed, on the side of the wall of the trench, by an exterior formwork plate 12 and, on the interior side of the tunnel, by an interior formwork plate 13.
  • the two formwork plates 12, 13 are spaced apart and are arranged parallel to the axis of the tunnel.
  • the formwork plates 12, 13 are, for example, made of asbestos-cement and delimit, with the external faces 14 of the sides 10 facing two successive shells 8, a vertical space between two successive shells 8. In this vertical space is inserted a concrete reinforcement 15.

  • the internal formwork plates 13 are significantly lower.

  • the transverse upper beams 17 in turn support upper reinforced concrete slabs 18, arranged so that each slab 18 is supported by its front edge on a transverse upper beam 17, and by its rear edge on the upper beam transverse 17 next, relative to the direction of advancement of the site, and also so that the lower surface of the slabs 18 is at the same level as the lower surface of the bases 11 in upper half-moon of the shells 8, so as to present these a continuous surface which can be left bare and constitute the ceiling of the tunnel, between the upper transverse beams 17.
  • the bases 11 in a half-moon have a thickness - (about 14 cm) greater than that of the slabs 18 - ( about 5 cm) and therefore protrude above the upper surface of the slabs 18.

  • a slab 21 is then poured between the two continuous bases 5 formed by the flanges 1 and the connecting flanges 4, cast therebetween, so as to cover the rebates 3 and 7.
