  • Such structures include amongst others blocks which are positioned on dikes, embankments, piers and the like.
  • the block shapes or other shapes have a wave breaking effect, which is desirable for defending the sand, clay or other material which form the bulk of the dike and the like.
  • Other shapes are also included, for instance plate shapes and the like.
  • use has been made of concrete elements. Although such elements provide a sufficient protective effect, nevertheless they exhibit some disadvantages as well. A serious disadvantage has an ecological background.
  • the object of the invention is therefore to provide an element which can be manufactured in an efficient way, and which has surface structures which are beneficial for obtaining particular effects which are less easily obtained by fully closed and smooth surfaces.
  • An example is an element for embankments, dikes, piers and the like which is able to combine the desired protective function with a satisfactory behaviour from an ecological view point.
  • Another example is an element which for instance provides sound attenuating properties.
  • open spaces be it of limited thickness, within the element.
  • These openings may take the form of slits, crevices and the like, and are quite suitable for stimulating biological growth of organisms such as plants en small animals.
  • an element of this type may be used for sound attenuating properties, in case the openings are selected in such a way that they are effective as for instance Helmholtz resonators.
  • the openings may have dimensions which range from several millimetres to several decimetres. The openings are obtained at the location of the granular material, which has been collected at several locations along the height direction of the element.
  • the position of these locations can be influenced by suitable alternating layers of the binder mix and amounts of granular material, such as sand.
  • suitable alternating layers of the binder mix and amounts of granular material such as sand.
  • crevices, slits and the like may be obtained. It is however also possible to form channels, panels and the like within the element. This is accomplished by the steps of:
  • the number of intermediate positions of the openings can be influenced in the aforesaid manner. This can in particular be accomplished by: -repeating several times the steps of introducing a quantity of a binder mix in the mould and of subsequently depositing a granular material on top of at most part of a quantity of a binder mix.
  • adjustments can be obtained by varying the thickness of the binder mix layers through pouring a specific amount of said binder mix in the mould each time, and also by adjusting the thickness of the amount of granular material.
  • the uncovered surface parts of the binder mix layers are allowed to adhere to each other, in such a way that the desired coherence of the element is obtained.
  • the granular material itself will exhibit little tendency to adhere to the binder mix.
  • this material will be loosened out of the crevices, slits, tunnels and the like which have formed in the element under the influence of the material.

Abstract

L'invention porte sur un procédé de fabrication d’un élément à partir d'un mélange de liant pouvant se solidifier ou durcir, lequel procédé consiste : - à utiliser un moule qui a au moins partiellement la forme de l'élément devant être fabriqué, - à introduire une première quantité d'un mélange de liant pouvant se solidifier dans le moule, - à  déposer un matériau granuleux sur au plus une partie de ladite quantité d'un mélange de liant, - à introduire une quantité supplémentaire de mélange de liant pouvant se solidifier sur la quantité précédente de mélange de liant et du matériau granuleux déposé sur celui-ci, - à solidifier le mélange de liant faisant ainsi adhérer les quantités de mélange de liant entre elles, - à éliminer de l'élément les quantités adhérentes de mélange de liant solidifié et de matériau granuleux entre lesdites quantités de mélange de liant solidifié du moule.
