  • I t Cl derpass may be dug out from a section of earth over which there already is a roadway. Pillars are constructed into the ground alongside the existing roadway and a superstructure is supported therefrom spanning the existing roadway. This superstructure is then utilized to support the load normally borne by the ex- [58] Field of Search........ 14/77, 75
  • This invention relates to a method for constructing an underpass beneath an existing overhead roadway.
  • This invention is directed to a method whereby an underpass may be constructed while maintaining traffic on the overhead roadway at less cost than permitted according to construction techniques.
  • An object of the present invention is a procedure for constructing a passageway underneath a pre-existant traffic roadway and is characterized in that pillars are sunk into the ground and that at least part of the upper roadway load is supported by said pillars before the excavation for the lower pathway is undertaken.
  • the superstructure of the upper roadway will rest on longitudinal springer structures which are placed on the pillars. As seen further below, the superstructure can be constructed rapidly.
  • the main excavations will be made following the erection of the superstructure, and they will be easy to carry out, without hampering the upper roadway traffic.
  • the pillars will facilitate the shoring operations.
  • FIG. 1 is a top view of a railroad embankment that is to be crossed by an underpass.
  • the first work stage is shown, that is, the construction of the foundations and pillars;
  • FIG. 2 is a section view taken along line lI-II of FIG. 1, showing the foundations and pillars of the first stage and also the longitudinal springers of the second stage;
  • FIG. 3 is a fragmentary view of FIG. 2, and enlarged, showing same at a further work stage;
  • FIG. 4 is a fragmentary longitudinal section showing other stages in the procedure (section along line lVlV of FIG. 1);
  • FIG. 5 is the same section as in FIG. 4, however after completion of construction.
  • FIG. 6 is a section similar to that of FIG. 3, showing a variation in procedure application.
  • the underpass may be intended, for instance, for a road sloping along line 3 of FIG. 2.
  • the roads width corresponds to the distance between the two straight lines (dashed) in FIG. 1.
  • 2 pits may be replaced by other excavation methods such as three-sided ones if the location is an embankment for instance.
  • the foundations are poured into these pits and then pillars 4 are constructed, for instance of reinforced concrete.
  • These pillars may be made of other materials, for example, metal.
  • the pillars may be replaced by sunk or driven piles; in that case the wood-shored excavations and the foundations are omitted.
  • two longitudinal springer structures 7 are constructed (FIGS. 2 and 3), which may be of reinforced concrete; metallic construction also is applicable.
  • each springer structure will be supported by at least three pillars. If the upper pathway is big and comprises several tracks, the number of longitudinal springer structures shall be increased.
  • the next stage namely, laying the superstructure, must be carried out quickly and preferably during nights, because its requires the temporary removal of the railroad track. It consists in removal of track 2 removal of ballast 8 and of terrain between springer structures 7,
  • the duration of traffic stoppage may be reduced by carrying out in steps the operations above and over several periods when the trains are not scheduled to run.
  • the procedures flexibility allows many combinations in this sense.
  • manufacture of the emplacement bed for the prefabricated components on the springer structures It may be made by means of rapid-setting synthetic resin mortar. A special device will be used to pour this bed when components 9 shall already have been emplaced; joining components 9 to each other, for instance by means of a rapid-setting synthetic resin mortar. Depending on circumstances, the bonding between prefabricated components may be reinforced by tie-rods, pre-stressed or not. water-proofing the upperside of the superstructure and the inner sides of the springer structures, the water-proofing material being protected by an appropriate sheating; removal of the supporting blocks, emplacement of ballast; and emplacement of protection barriers.
  • FIG. 4 shows one may progress in stages, emplacing planks 13 from top to bottom, lines 14 and 15 showing the successive clearing stages for the lower passageway.
  • ground consolidation by injection may be appropriate before excavating laterally.
  • lateral excavation methods may be used, for instance by vertical in lieu of horizontal sections, or by making use of vertically emplaced earth sustaining means, etc.
  • shoring means 13 one may directly undertake pouring concrete in successive sections. After the pillars have been cleared, they may eventually be covered, even reinforced. This would be especially the case if they have been made initially of metal or are in the form of concrete piles.
  • a draining jacket 16 will be placed together with a wall 17 against the lateral sides.
  • the construction will be finished by preparing the ground of the lower passageway either for a highway or for one or more railroad tracks, etc.
  • the pillars 4 and springer structures 7 are constructed in the same manner as for the first execution of the procedure.
  • the ballast 8 is removed from track 2 so as to allow inserting temporary metallic springer structures 19, which are 2-3 m apart and the ends of which rest on springer structures 7, underneath the sleepers.
  • the track must be reinforced by bundles of rails 11 or by shaped-profile iron bars. This operation may be undertaken in stages and betwen train passages.
  • the excavation proceeds fully underneath the bridge.
  • the superstructure will be a solid slab.
  • a prefabricated one may also be considered.
  • the coffering may be erected after excavation, and the concrete may be poured between metal beams l9.
  • the procedue may also be used when the overpass is still without traffic.
  • the supports and the superstructure as for a traditional bridge, it will be often preferable to make use of the initial presence of the terrain in order to construct the bridge framework.
  • the described procedure therefore may be applied fairly generally. It simplifies work when a bridge superstructure must be made at a site where the terrain, initially filled up, must be dug up for setting up a lower pathway.
  • the upper part of the bridge no longer is necessarily constituted by longitudinal springer structures that are connected by a superstructure.
  • This upper part may be made up of reinforced concrete (solid slab, caisson slab, semi-solid slab etc.) which makes use of the raised earth platform as a work area. As in the preceding cases, this upper part will rest on previously built pillars buried in the ground.
  • springers parallel to the upper roadway and resting on the upper end of said pillars, said springers being outwardly of a predetermined traffic gauge necessary for said upper roadway, placing a superstructure on said springers, said superstructure comprising transverse beams arranged side by side and having their ends resting on the springers, then completing the roadway portion on said superstructure, said superstructure emplacement and roadway portion completion being carried out step by step,
  • said lateral excavations being carried out step by step with pro gressively strengthening the side faces of the underpass from the level of said springers down to the level of a lower platform of said underpass, and completing said lower platform.
  • a procedure according to claim 1, comprising sinking said pillars in the ground and finishing said pillars after completion of said excavations in order to constitute the constructions final pillars.
  • a procedure according to claim 1, comprising driving said pillars in the ground and finishing said pillars after completion of said excavations, in order to constitute the constructions final pillars.
  • a procedure according to claim 1, comprising constructing said pillars of metal components and finishing said components after completion of said excavations in order to constitute the final construction pillars.
  • a procedure according to claim 1, comprising constructing said, pillars of metal components and modifying said components after completion of said excavations in order to constitute the final construction pillars.
