Definitions

  • the present invention relates to a rapid method of construction of upper track bridges made using prefabricated elements.
  • the invention is particularly applicable to the erection of raised road bridges and, more particularly, for the crossing of expressways for which traffic can, in general, be interrupted only for short periods of time.
  • the invention aims to achieve a bridge quickly and economically by causing a minimum of disruption on the track it spans.
  • Another object of the invention is to produce such a bridge having an aesthetic appearance.
  • Another object of the invention is to provide such a bridge by a method adaptable to a wide variety of applications by simply changing the dimensions and the arrangement of the parts used.
  • the invention also aims to create a method of constructing a bridge which is such that this construction can be easily planned and possibly spread over time, while very substantially reducing traffic disruptions and other disadvantages that usually involve such work.
  • the subject of the invention is a method of constructing a top-track bridge, provided with an apron supported by piers and two abutments, produced using precast concrete elements, which includes the operations following: - digging of foundations of piers, these foundations being arranged perpendicular to the axis of the bridge deck, at the location of the piers and abutments of the bridge; - pouring of foundation pedestals for the bridge pedestals; these pedestals, the cross section of which looks like an inverted T, have a sole and a bait; the upper face of this pedestal primer is provided with means allowing the secure with the free ends of columns that this primer of pedestal is intended to support; - prefabrication, by molding, of concrete portals; these gantries are each formed of two columns connected perpendicularly to the ends of a median beam having, on the side opposite to the columns, a rectangular face which is substantially planar, the length of which, from one end of the column to the other, corresponds to the length of a span of the
  • the prefabricated gantries can be made according to different techniques, depending on the constraints imposed by the specifications, in particular in terms of cost and weight and according to the span of the spans.
  • We can thus use the reinforced concrete technique or that of prestressed concrete.
  • prestressed concrete it is possible in particular to use greased monotoron cables.
  • the method according to the invention uses, as means of attachment between the free end of the columns of the prefabricated porticoes and the primer of the pedestal of the foundation pedestals, metal pins protruding vertically from the upper face of the primer a pedestal, the free ends of the columns of the prefabricated porticoes having corresponding cavities; the said metal pins are introduced into the corresponding cavities during assembly. These elements are joined together by injecting a cement grout into said cavities.
  • the method according to the invention further comprises the following operations: - installation of a drainage means against the face of the end pedestals located on the side of the access slope; - construction, at each end of the bridge, of two return walls erected between the end pedestal and the said embankment, vertical to the limits lateral to the upper track of the bridge, and - backfilling, at each end of the bridge, between the two walls in return, and completion of the slopes in quarter cone.
  • the return walls are formed of concrete slabs, the two return walls located on either side of the same embankment being interconnected by means of tie rods fixed to said concrete slabs.
  • the method according to the invention further comprises the following operations: - installation of a drainage means against the face of the end pedestals located on the side of the access slope; - burial of these end pits by backfilling, the slopes of these backfills connecting to those of the shoulders of embankments, and - completion of slopes in quarter cone.
  • foundation pedestals of a bridge erected according to the invention are advantageously made in armored excavations.
  • the object of the invention is also a bridge produced according to one of the methods described above.
  • Fig. 1 is a perspective view of a bridge 1 in progress.
  • Bridge 1 is illustrated in this way to better highlight the essential elements of its construction; we deliberately omitted to represent the ground surface which is located approximately halfway up the foundation plinths, as described below.
  • Bridge 1 is made up of four spans 2, 3, 4, 5. It spans a double, fast-moving lane, supported by the central berm 6 which separates the two carriageways 7.
  • Each span 2, 3, 4, 5 is composed of several prefabricated gantries 8, joined by the edge.
  • the middle beam 9 of these gantries 8 forms the support for the deck of the bridge 1; the two columns 10 connecting perpendicularly to the ends of this median beam 9 form the corners 11.
  • the end face of each of these columns 10 rests on a foundation base 12 in inverted T which extends perpendicular to the longitudinal axis of the bridge 1.
  • the foundation pedestals 12 include a sole 13, which can be built without significantly disturbing traffic, on the central berm 6 separating the two carriageways 7 from the main track.
  • the stem of the inverted T forms a primer 14 supporting the 11 piers.
  • the prefabricated gantry cranes 8 are gripped by a lifting machine and deposited in place so that each end face of the columns 10 rests on the pedestal primer 14 of a pedestals 12, the pedestals 12 forming the bases of the pedestals 11 of the deck 1 and abutments.
  • the columns 10 and the corresponding primer 14 have the appearance of a continuous pail veil.
  • the prefabricated porticoes 8 forming the lateral spans 2, 5 can be partially buried in the slopes 15 or lean against them, which modifies the silhouette of the structure according to urban planning wishes.
  • the corners 11 forming the ends of the deck 1 have at their top a heel 16.
  • Fig. 2 shows, in section, a bridge 1 constructed according to the method of the invention at another stage of production.
  • the four spans 2, 3, 4, 5 completed are joined by pouring an additional reinforced concrete slab 17 (second phase concrete 17) on the upper face of the prefabricated gantries 8.
  • a floating slab 18 is arranged on each side of the bridge 1, and rests by one of its ends on the heels 16 at the head of the end gantries 8.
  • the abutment 19 of bridge 1 is backfilled with a slope.
  • the slope of each abutment slope 19 located below the end pedestal 20, is connected by a quarter of a cone to that of the slope 15 supporting the secondary track.
  • Fig. 3 is a side view of another bridge 21 according to the invention, provided with solid abutments 22.
  • Each abutment 22 is backfilled behind the sides 11 of the end spans 3, 5 and taken between two return walls 23.
  • These walls 23 are consisting of prefabricated plates, one connected to the frame by transverse tie rods 24.
  • Fig. 4 is a section through a construction detail of FIG. 3 and shows an intermediate stack of deck 1.
  • the sole 13 of the base 12 of the stack supports a primer of pedestal 14.
  • This primer of pedestal protrudes slightly from the ground level.
  • the upper face of this primer 14 has dimensions which correspond to those of a double row of columns, of prefabricated gantries 8 corresponding to two adjacent spans of the bridge 1.
  • these pins 25 serve as guide elements for positioning; the prefabricated portal frames 8 are held in place by their own weight.
  • non-shrinking mortar 28 is injected through these vents 27, between the pins 25 and their sheath 26 and into the gaps remaining between the end face of the columns 10 and the upper face of the primer caps 14; a simple connection is thus obtained at the base of the pedestal 11, which allows the prefabricated gantry cranes 8 to work in gantry gantry cranes.
  • This link transmits vertical or horizontal forces without repeating moments.
  • the column-sole connection can of course be carried out by any other equivalent means, such as an anchoring barrel, for example.
  • Fig. 5 shows another construction detail of FIG. 3, and represents the base of a bridge end pedestal.
  • the foundation pedestal 12 also includes a sole 13 and a sidewall primer 14.
  • pins 25 protruding from the pedestal 12 serve, jointly with the sleeves 26 arranged in the columns 10, to be formed after injection of cement grout 28 , a single link at the base of each gantry 8.
  • the end pedestal is backed by the embankment 15 in backfill (Fig 3).
  • the wall formed by the faces external of the columns 10 is covered with geotextile 29.
  • the water is drained by the geotextile 29 and brought into a chute 30 formed on the upper face of the primer 14.
  • This chute 30 guides the drainage water towards a discharge conduit 31 which passes through the base 12 and opens outwards where a flow channel can be formed.
  • Fig. 6 is a sectional view along a vertical plane perpendicular to the axis of the deck.
  • the beams 9 forming the middle part of the gantries 8 are seen in section and have a substantially trapezoidal section.
  • the gantries 8 being joined in an almost contiguous manner, form a decking surface onto which a second phase concrete 17 can be poured directly without formwork.
  • the "V" joints, 32, between the horizontal beams 9 of the gantries 8 are previously stuffed with kift concrete or rich mortar with possible interposition of a strip of plastic foam or bottom of the joint.
  • the second phase concrete 17 is poured over the entire span, with a light reinforcement. Reinforcements of localized reinforcements prevent the formation of cracks without resuming significant negative moments on support of the various spans of the decking.
  • the section of the median beams 9 is calculated in such a way that these elements can, without reaching an excessive weight, take back their own weight alone and that of the second phase concrete 17 with a deflection sufficiently reduced so that it is not necessary to lay props. This avoids, on the one hand, an additional operation, and, on the other hand, the interposition of retaining pieces whose presence would clutter the spanned roadway 7, preventing normal circulation thereon, which would go against the objectives of the invention.
  • the second phase concrete 17 forms an integral unit with the middle beams 9 of the gantries 8.
  • a sealing layer 33 is produced above the second phase concrete 17, after which the deck 1 finishes are laid, in particular the road surface 34, the water nets 35, the wheel guards 36, the sidewalks 37, finally railings 38 and skirts 39.
  • the prefabricated gantries 8 are put in place by means of a lifting device (such as a swiveling crane) (not shown).
  • a lifting device such as a swiveling crane
  • the site can be organized so as to assemble the spans 2, 3 in an extremely short period of time.
  • a mobile crane is brought to the site and moves parallel to the axis of the deck to be assembled.
  • the gantries 8 are arranged vertically, juxtaposed in a row parallel to the axis of the main track.
  • the scope of the crane is chosen such that a gantry crane 8 can be brought into place in a single operation.
  • the gantries 8 given their dimensions, are preferably made in fairground prefabrication, on the construction site, by the roadside. These gantries 8 will be stored over a distance not exceeding the range of the assembly crane. If several works are planned along the same road, the formwork can be moved from one to the other during the advance of the works.
