Definitions

  • the present invention relates to a device for spreading and vibrating in the mass of pavement materials, of the type comprising a vibrating box formed by two vertical walls and a bottom on which vibrators are fixed, the box being open at its upper part and at an exit zone of the materials, an adjustment system being provided at the exit zone for leveling the surface of the spilled material.
  • French patent 625 815 describes such a device in which the box consists of a flat-bottomed box arranged in height which is followed by a funnel or discharge pipe allowing the spreading of concrete.
  • this device makes it possible to densify only materials having thixotropic properties.
  • Pavement materials are understood to mean all the materials constituting pavements such as gravel, sand, fine soil, mixed with any binder (hydraulic or bituminous) or without binder, with water or without water, or mechanically stabilized.
  • Some spreading materials for example the paver or autograde, during the spreading of the material, try to arrange the aggregates together, thus creating a precompaction by vibrating by contact on the upper surface of the layer of materials with either a vibrating formwork or a vibrating table.
  • the vibrations thus transmitted to the aggregates are quickly absorbed by the thickness of the material, and only the aggregates near the vibrating surfaces are put in place, arranged and easy to compact.
  • the aggregates located in the middle or at the bottom of the layer, little influenced by the surface vibration, are therefore not or little arranged. This makes subsequent compaction difficult at these levels.
  • the surface materials are well compacted while those at the bottom of the layer are only weakly compacted. We then observe in the pavement layers thus produced strong density gradients which reduce the performance of the material and the structure.
  • the aim of the present invention is to propose a device of the type mentioned above making it possible to better rearrange the aggregates of both thixotropic and non-thixotropic materials for pavement layers (bases, foundation, and of shapes, surface, etc.), during spreading, and pre-compact them to facilitate subsequent compaction of these materials.
  • the object is achieved by the fact that the vibrators are mounted in the lower part of the bottom so as to impose on the box an essentially horizontal vibration in the horizontal plane parallel to the surface on which the material is to be spread, and in that the bottom is curved and ends at its lower part with a horizontal part which is in contact with the surface on which the material is to be spread and which makes it possible to vibrate the material spread at the base of the layer.
  • FIG. 1 shows a known spreading device
  • FIGS. 2 and 3 respectively represent the perspective and the section of a device according to the present invention
  • FIGS. 4 and 5 show details of the embodiment of the lower part of the vibrating box.
  • the reference 7 represents the vibrating soles or ladies
  • the reference 8 the distribution screw
  • the reference 9 the vibrating formwork
  • the reference 10 the layer of widespread material.
  • the device according to the invention consists of a vibrating metal box having a bottom formed by a curved plate 1 and having two side walls 2.
  • the box is not closed at its upper part or on the side from which it exits the spilled material.
  • the box is vibrated at its base by vibrators 3.
  • the lower part of the box in contact with the surface of the ground on which the material is to be spread must be flexible in order to match the unevenness of the ground. It can be carried out for example, either using flexible membranes 4 made of rubber or other flexible material fixed to the box (fig. 4), or by the fact that the bottom 1 ends with blades 5 cut out from the sheet of the bottom 1 (fig. 5).
  • the box is partially closed on the side of the spilled material by any system allowing the thickness of the spilled material to be adjusted.
  • This can be constituted for example by a vibrating blade 6 adjustable in height according to the desired profile of the widespread layer and independently of the box or by a system of rotating grooved drum.
  • the walls 2 may have a shape which allows the side walls of the layer of spread material to be molded directly.
  • vibrators can be mounted at this location.
  • the main vibration of the box is carried out using vibrators 3 mounted on a horizontal beam welded to the bottom 1.
  • the vibrators are mounted so as to impose on the box a vibration essentially contained in the horizontal plane parallel to the surface of the spilled material, the vertical component of the vibration is almost zero or negligible with respect to the amplitude of the horizontal vibration. This can for example be obtained by vertically arranging the axes of the imbalance vibrators. If the power of the vibrators is insufficient, we can add in this case other rows of vibrators parallel to the first row.
  • the device can be mounted either on a self-propelled cart or on one of the traditional spreading systems.
  • the direction of movement of the system is indicated by the arrow in Figure 2.
  • the material is poured into the box at its top.
  • the vibration of the bottom 1 and the walls 2 by the vibrators 3 and the advancement of the device bring the material down to the spread layer, arrange the aggregates throughout the thickness of the layer and precompact the material, this facilitates subsequent compaction by traditional means (vibrating tables, vibrating soles or vibrating or pneumatic compactors).
  • Figure 3 is shown an example of compacting by vibrating soles or checkers 7.
  • the reference 11 represents the loading of the material.
  • the use of this device makes it possible to lighten the traditional compaction workshop, and consequently reduce the cost price of the implementation.
  • the materials of the pavement layers thus produced are more compact and more homogeneous in density.
  • the quality of the plaster and the mechanical performance of the pavement are improved.
