Definitions

  • the present invention relates to precast concrete elements for the construction of retaining walls.
  • the technical sector of the invention is the manufacture of precast concrete elements for public works.
  • One of the main applications of the invention is the construction of retaining walls of inclined or vertical slopes, having a straight or curved alignment and associated with sound absorption properties, and in which one wishes to preserve the possibility of growing plants .
  • n ° FR 2421243 filed by the COMPANY ALBERT PELLER et Cie which describes sound insulation walls, composed of transverse beams and interwoven longitudinal beams with the previous ones which form two continuous chaining and the longitudinal beams located at the front of the wall have a trough-shaped section.
  • the transverse and longitudinal beams frame rectangular wells filled with topsoil.
  • patent FR 2435661 from the SABLA company describes box walls which include transverse walls composed of beams placed one above the other; façade plates inclined towards the outside when rising, which are placed in notches of the transverse beams and of the transverse bars or beams which connect the rear ends of the beams.
  • the small relative dimensions of these elements can allow, depending on their configuration, to follow curved slope profiles while the elements of the first category, which are longer, do not adapt to all the desired curves.
  • slope support elements each consisting of a parallelepipedal block having female grooves in triangle on all its faces and which thanks to male keys of square section inserted between the blocks and slid in the grooves facing each other join the elements together; by the play of several parallel and perpendicular grooves, it is thus possible to follow an inclined slope, to make angles, but not to follow curves or to revegetate said slope.
  • German patent application No. DE 3118487 filed on 05/03/81 by Mr. REINHARD Juraschek describes cylindrical elements with a vertical axis, the section of which is in the form of puzzle pieces with two grooves in two opposite vertical faces and two female grooves compatible with the former on two other opposite vertical faces, which elements can be connected by elongated parts making a ball joint between two female grooves of two basic elements and thus making it possible to follow a curve.
  • Patent application FR 2570411 filed on 09/19/84 by Mr. Pierre CHAMBREUIL relates to "monoblock elements for the consolidation of double walls"; these elements have a flat face and the opposite face consisting of coarse and female grooves which can cooperate and self-lock with those of other elements which are assembled in staggered rows in the two directions of the plane formed by the wall that you want to build: it is then self-locked without mortar or cement, but cannot be tilted or curved and is therefore not suitable for an embankment.
  • the problem is therefore to be able to produce prefabricated concrete monoblock elements for the constitution of retaining walls, the shape and the imprints of the faces allow a manufacture with conventional and standard automatic machines, and of which said single external shape makes it possible to produce vertical or inclined walls, thickening of these walls by adding these elements assembled together one behind the other while maintaining the curve or straight alignment; the dimensions of these elements being compatible with manual handling and the interior shape which can be adapted to allow the inclined retaining wall to be planted and to absorb radiating noise.
  • the present invention relates to a one-piece element according to claim 1 appended.
  • the objective of the present invention is achieved with a monobloc element as above and comprising a single groove on each of its lateral faces, on one side in female dovetail shape and on the other in shape male dovetail, which forms tolerate between them an angular rotation of an element compared to that which is adjacent to it.
  • said one-piece element comprises two guide grooves on the rear face in the form of a male dovetail and two on the front face in the form of a female dovetail.
  • the one-piece elements such as above additionally comprise a central cavity open on the upper and lower faces and for other elements, said cavity is closed on the side of the upper face and open on the lower face thus that on the front face by at least one chute communicating with a groove of female guide of this face.
  • these elements by assembling one above the other, one next to the other and one behind the other can constitute any kind of retaining walls: straight or inclined and at a variable angle, frontal, concave or convex curvature, rear reinforcement; in the case of inclined walls, certain elements can then be re-vegetated and in all cases certain elements can be noise absorbing.
  • these elements may be of small size, of the order of approximately 20 kilos, to be able to be handled manually; they do not require any parts or intermediate elements to fit and fix them; their implementation is therefore simple and rapid.
  • Figure 1 is a perspective view of two one-piece elements ready to be stacked.
  • Figure 2 is a view in four planes of a standard element.
  • Figure 3 is a view in four planes of an element acoustic.
  • Figure 4 is a vertical sectional view of a retaining wall.
  • Figure 5 is a horizontal sectional view of a retaining wall.
  • Figure 1 is a perspective view of two monoblock elements, one of which can be qualified as standard 1 and the other as acoustics 2 and ready to be stacked one on the other along their common vertical axis xx 'to constitute a column.
  • the standard element 1 is described in FIG. 2 in detail, the acoustic element 2 in FIG. 3.
  • the block elements are preferably of rectangular, rectangular shape whose length is in the direction of the depth of the wall they constitute.
  • the views of 2A and 2C are those from below and from above, that is to say from the faces 18 and 17.
  • the outer surfaces 20 and 21 of these lateral grooves 10 and 11 actually act as a ball joint to allow the rotation of an element relative to the following: their shape must therefore be of spherical or conical type enveloping a sphere and / or allow sufficient play while those of the grooves 8 and 9 can be of any other shape.
  • the so-called Helmholtz cell is obtained by threading into said cavity 4, 5 sheaths of suitable synthetic materials.
  • Figure 4 is a vertical sectional view BB according to Figure 5 of a retaining wall of an embankment 23, and consisting of one-piece elements 1 and 2 as described above.
  • Elements 1 and 2 in fact play the same role to constitute the front face of the wall by stacking one above the other, either vertically like those of the second and third rows from the bottom, or with a fruit towards the rear, equal to the interval d between two grooves 6 like those of the fourth and fifth rows, at two intervals d between two grooves 6 like those of the third and fourth rows, at three intervals d between two grooves 6 like those of the first and second rows; and more or less steep slopes could be achieved in this way.
  • rows where the offset is large such as the first and fifth for example, can then be planted with plants.
  • the elements can be stacked to form acoustic absorption cells as with the second and third rows.
  • the front elements 1 and 2 in a particular embodiment may comprise only a surface offering only an aesthetic shape and then be used only to produce the visible wall of said retaining wall.
  • Figure 5 is a horizontal sectional view AA according to Figure 4 of a retaining wall of a slope 23, and consisting of one-piece elements 1 for the front face of this wall and elements 22 to reinforce said wall to the back.
  • the lateral faces of these elements 22 are planar and the element is then used only to make thickenings for reinforcing the front wall of said wall.
  • the elements 22 when the wall is curved, concave in shape as in the figure, but it could be convex, the elements 22 must then approach or move away: when they get closer if their corner touch, we delete one on two to continue extending the reinforcement if necessary.
  • the maximum angle of curvature can be variable, for example up to four degrees.
  • the hollow elements 1 and 22 can also be filled themselves with materials in order to constitute a weight wall.
