Definitions

  • the object of the present invention is to provide improvements to the construction of various civil engineering structures such as retaining walls, bank protections or embankments, by means of prefabricated stackable boxes whose compartments are intended to receive a filling in various materials and whose overall rigidity of the work is ensured by vertical and horizontal stiffeners in reinforced concrete, conferring at the same time advantages of confinement to the product placed in the compartments of the caissons.
  • Retaining structures, walls in particular, are essentially made using different techniques such as massive stone walls (since antiquity), reinforced concrete walls, prefabricated elements that are transportable or cast on site, baskets in metal mesh (gabions) filled with stone, solid or honeycomb stackable concrete blocks according to several systems with often facial finishes imitating stone or other materials, prefabricated and stackable concrete elements for planters and green walls , or shuttering blocks for small structures.
  • massive stone walls since antiquity
  • reinforced concrete walls prefabricated elements that are transportable or cast on site
  • baskets in metal mesh (gabions) filled with stone solid or honeycomb stackable concrete blocks according to several systems with often facial finishes imitating stone or other materials
  • prefabricated and stackable concrete elements for planters and green walls or shuttering blocks for small structures.
  • the solid walls, the elements and the prefabricated concrete blocks intended for the realization of retaining walls constitute the major part of the whole of the work as well in the face of facing as in the structural part, but are dissociated from the part drainage and the first part of the backfill
  • Gabions have very good qualities for letting runoff water through and correctly absorb, due to their flexibility, variations in the terrain on which they are placed.
  • bridge abutment structures or embankment restraints under road and rail traffic lanes are made with mixed techniques of facing in precast concrete elements and embankment in reinforced earth.
  • Embankment structures or river or sea bank restraints are also carried out with these mixed techniques, or by rockfill dumped in bulk or placed with a mechanical shovel, sometimes bonded by filling concrete poured into the cavities to form the shell. of the work.
  • Some structures are also made of shuttered concrete poured on site according to the possibilities and the constraints of water levels.
  • embankments are often made in relation to the mechanical qualities of the latter and the geographical proximity of the site for reasons of transport costs.
  • Each of the documents JPS59150810A And JPS5838826U discloses a box of parallelepiped shape delimited by long and short peripheral vertical walls, which box comprises interior compartments separated by vertical partitions, and at least one interior central column placed at the junction of said interior partitions.
  • the invention aims to provide a prefabricated product capable of producing a stable structure and different conformations.
  • Another object of the invention is to provide a prefabricated product which is very insensitive to erosion, to torrential rain runoff, to floods, to the effects of breaking waves, for the construction of various structures: retaining walls, crossing or retaining watercourses, protection of river and maritime banks, green walls, planters, etc....
  • the characteristics of the prefabricated compartmentalized box of the invention provide both great simplicity in its implementation and allow, by composition of assembly, to produce large-scale works with the same element which stacks and binds solidly, also allowing the burial of more or less polluted products in these works.
  • this caisson facilitates the construction of works in the presence of water by avoiding the phases of formwork, reinforcement, pouring, stripping, drying in situ as well as most of the risks inherent in landslides and/or rising water. both river and sea.
  • the invention relates firstly to a box of parallelepiped shape delimited by long and short peripheral vertical walls, which box comprises interior compartments separated by vertical partitions, and at least one interior central column which is placed at the junction of said vertical partitions (3 and 3c), said box is characterized in that said at least one inner central column (7) extends from a multi-position interlocking device (8) located in the lower part of the box (1) , to a fitting device (9) located in the upper part of said box (1).
  • the interlocking devices confer on the box of the invention, and on the work produced from a stack of such boxes, great modularity in the shape of the works since the juxtaposed and superimposed boxes can be offset from each other.
  • the possibility of such an offset also ensures the stability of the structure, in particular by the possibility of achieving a significant inclination towards the rear of the structure or of a part of the structure, this inclination also being referred to as "fruit" in the field.
  • the invention finally relates to a civil engineering structure comprising at least two caissons of the invention,
  • the structure of the box of the invention in particular its compartments, ensures rapid pouring of concrete reinforcement elements, reinforced or not, in the box without additional formwork, between two tides for example.
  • the compartments can be open or closed at the bottom depending on the destination of use.
  • the ratio of the dimensions (length/width) of the caisson makes it possible to position the caissons of a structure in the same plane, either in the same direction of alignment, or with an alignment offset in this same direction, or staggered (checkerboard).
  • the alignment offset of each upper row of boxes can be low or higher.
  • the boxes can be positioned, for simple works, with their long wall in front of the work to be carried out, thus offering two minimum compartments to be filled in depth or, with their short wall in front of the work to be carried out, three compartments minimum to fill in depth.
  • the compartments of the caissons placed on the front of the structure can be filled with concrete in order to form a shield or a shell, and the compartments located at the rear can be filled with draining materials or backfill.
  • a massive structure of large dimensions such as a structure for the protection of river or maritime banks, can easily be formed by several caissons juxtaposed one behind the other, staggered or not at each higher row.
  • the layout and shape of the reinforced concrete stiffeners makes it possible, after casting them, to ensure both a solid hold of the caissons between them as well as total containment, like a "sarcophagus". , materials placed in the compartments in any row offset configuration.
  • the box is of parallelepipedal shape, provided with interior compartments separated by vertical partitions, the long and short peripheral vertical walls of which comprise vertical recesses in indentation open towards the outside and arranged at regular intervals, interior central columns placed at the junction of the interior partitions and connecting a combination of multi-position female interlocking devices, in the lower part, to a female interlocking device, in the upper part, itself comprising a lifting and handling, and on its upper and lower horizontal edges of the horizontal recesses open outwards.
  • the box can be positioned by superposition either exactly plumb with the lower box, or slightly offset in a single direction, or simultaneously in two longitudinal and transverse directions, on the same horizontal plane, or offset more significantly than one third or two thirds of its length on the same horizontal plane in order to give a significant backward inclination otherwise called "fruit" to a retaining wall or a stepped “pyramid” style recess for such a wall or a bank protection or embankment structure.
  • This offset is made possible by the presence of the interlocking devices 8.9 and more particularly the multi-position interlocking device 8.

  • these recesses are preferably of rounded section rather than angular.
  • the vertical lateral recesses can be of semi-frustoconical shape in order to ensure the continuity of the section of the vertical stiffeners in the event of a shift in the positioning of the boxes in superposition, in the horizontal plane, according to the possibilities offered by the interlocking devices placed on the underside of the box.
  • the vertical recesses indentation of the vertical side walls can be of semi-frustoconical shape, the small section of which is located at the bottom of the wall and the large section is located at the top of the wall.
  • the lateral horizontal recesses make it possible, by juxtaposition of two caissons, to form a formwork cavity in order to receive the horizontal reinforced concrete structure holding the caissons together and the whole of the structure. composed by all the boxes.
  • these recesses are preferably rounded in shape rather than angular.
  • the horizontal lateral recesses may be of extended shape in order to ensure the continuity of the section of the horizontal stiffeners in the event of a shift in the positioning of the boxes in superposition, in the horizontal plane, according to the possibilities offered by the interlocking devices placed underneath. -front of the box.
