Description

  

  Procédé de     fabrication    d'un mur de soutènement à l'aide de dalles  et mur obtenu par ce procédé    L'invention a pour objet un procédé de fabrication  d'un mur de soutènement, caractérisé par le fait qu'on  dresse face à face deux dalles destinées à former les  faces     avant    et arrière du mur et qu'on coule une masse  de remplissage entre lesdites dalles.  



  L'invention a également pour objet le mur de sou  tènement qui peut être obtenu par la mise en     oeuvre    de  ce procédé.  



  Le dessin annexé représente, à titre d'exemple, un  dispositif pour la mise en     oeuvre    du procédé selon  l'invention.  



  La     fig.    1 illustre une élévation d'un tel dispositif ;  La     fig.    2 est une coupe selon     II-II    de la     fig.    1.  Pour fabriquer un mur de soutènement en     mettant     en     oeuvre    le procédé selon l'invention, on forme d'abord,  par tous procédés connus, deux dalles 1 et 2 dont la  première est constituée par une plaque de béton 3 enve  loppant un treillis métallique 4 ainsi que le pied de  poutrelles composées 5, parallèles entre elles, faisant  saillie sur la plaque.  



  La seconde dalle 2 est dans l'exemple représenté  constituée par un agglomérat d'agrégats légers 6 soudés  l'un à l'autre par un liant relativement léger de manière  à laisser subsister des espaces entre les agrégats, ce qui  rend l'agglomérat obtenu perméable à l'eau.  



  Dans cette masse d'agrégats sont noyés un treillis 7  ainsi que le pied de poutrelles 8 faisant saillie sur la  dalle et de constitution similaire aux poutrelles 5 pré  cédemment citées.  



  La face de la dalle     tournée    vers l'intérieur du mur  à constituer est recouverte par une couche de matière  étanche rapportée.  



  Pour procéder à la construction d'un mur de soutè  nement comportant les dalles 1 et 2 précédemment décri-    tes, on commence par évacuer la terre que ce mur est  appelé à soutenir de manière à laisser un espace suffi  sant derrière le mur à construire.  



  On coule ensuite un socle 10     (fig.    1) présentant une  embase 11 contre les deux côtés opposés de laquelle on  applique les deux dalles 1 et 2 maintenues en position  dressée par des barres d'appui 12 et 13 faisant prise,  par leur extrémité supérieure, sur les dalles 1 et 2, aux  deux tiers de leur hauteur totale, et par leur extrémité  inférieure sur des poutres de bois 14 arrimées au sol  grâce à des piquets 15. Des entretoises supplémentaires  16 empêchent tout basculement des dalles 1 et 2.  



  Le montage de la dalle 1 s'effectuera de préférence  après avoir placé contre la dalle 2 une armature métalli  que 17     (fig.    2) qui sera reliée aux fers saillants de l'em  base 11.  



  On coule ensuite du béton dans l'espace compris  entre les dalles, ces deux dalles formant donc coffrage  en même temps qu'elles constitueront par la suite les  éléments de surface du mur obtenu.  



  Lorsque la prise du béton est terminée, on démonte  les barres 12 et 13 ainsi que les entretoises 16 et les  poutres 14.  



  Il sera alors possible de remplir de terre l'espace  vide créé à droite de la dalle 2     (fig.    1) et de donner  donc au mur sa vraie fonction de     soutènement.     



  Le procédé décrit permet de réaliser les murs avec  une célérité surprenante, les travaux de coffrage et de  décoffrage usuels étant remplacés par le simple montage  des deux dalles 1 et 2.  



  L'emploi de la dalle formée d'un agglomérat per  méable à l'eau a essentiellement pour but de permettre  l'écoulement de l'eau de pluie le long du mur sans  créer de pression exagérée sur ce mur.



  Method of manufacturing a retaining wall using slabs and wall obtained by this method The subject of the invention is a method of manufacturing a retaining wall, characterized by the fact that two face to face slabs intended to form the front and rear faces of the wall and that a filling mass is poured between said slabs.



  Another subject of the invention is the retaining wall which can be obtained by implementing this method.



  The appended drawing represents, by way of example, a device for implementing the method according to the invention.



  Fig. 1 illustrates an elevation of such a device; Fig. 2 is a section on II-II of FIG. 1. To manufacture a retaining wall by implementing the method according to the invention, firstly, by all known methods, two slabs 1 and 2 are formed, the first of which consists of a concrete plate 3 enveloping a trellis. metal 4 as well as the foot of composite beams 5, parallel to each other, projecting on the plate.



  The second slab 2 is in the example shown constituted by an agglomerate of light aggregates 6 welded to each other by a relatively light binder so as to leave spaces between the aggregates, which makes the agglomerate obtained permeable to water.



  In this mass of aggregates are embedded a trellis 7 as well as the base of beams 8 projecting from the slab and of similar construction to the beams 5 previously mentioned.



  The face of the slab facing the inside of the wall to be formed is covered by a layer of attached waterproof material.



  To proceed with the construction of a retaining wall comprising the slabs 1 and 2 described above, we begin by removing the earth that this wall is called upon to support so as to leave sufficient space behind the wall to be built.



  Then casting a base 10 (fig. 1) having a base 11 against the two opposite sides of which are applied the two slabs 1 and 2 held in upright position by support bars 12 and 13 taking hold, by their upper end , on slabs 1 and 2, at two-thirds of their total height, and by their lower end on wooden beams 14 secured to the ground by means of stakes 15. Additional spacers 16 prevent any tilting of slabs 1 and 2.



  The assembly of the slab 1 will preferably be carried out after placing against the slab 2 a metal frame 17 (fig. 2) which will be connected to the protruding bars of the base 11.



  Concrete is then poured into the space between the slabs, these two slabs therefore forming shuttering at the same time that they will subsequently constitute the surface elements of the wall obtained.



  When the concrete setting is complete, the bars 12 and 13 are removed as well as the spacers 16 and the beams 14.



  It will then be possible to fill the empty space created to the right of slab 2 (fig. 1) with earth and thus give the wall its true supporting function.



  The process described makes it possible to produce the walls with surprising speed, the usual formwork and stripping work being replaced by the simple assembly of the two slabs 1 and 2.



  The main purpose of using the slab formed of an agglomerate permeable to water is to allow rainwater to flow along the wall without creating excessive pressure on this wall.
