- the compacting tool 1 consists of a tooth holder 2 on which are mounted a tooth 3 and a sole 4.
- the tooth 3 constitutes the part of attack of the compacting tool. It takes the form of a wedge, having a lower face and an upper face 5 which meet at a leading edge 6.
- Figure 2 shows an example of how to fix the tooth 3 to the door 2.
- the attachment is done by interlocking a protruding portion 7 of the tooth holder 2, forming a tenon and here taking the form of a wedge, and a hollow portion of the tooth 3 , forming a complementary shape mortise.
- Fastening is provided by a key 8 which is inserted into through openings 9, 10 provided in the transverse walls of the tooth 3 and the protruding portion 7 of the tooth holder 2. Any other method of attachment known in the art. technique can be envisaged, the tooth 3 and the tooth holder 2 can also be designed in one piece.
- the sole 4 of the compacting tool extends the lower face of the tooth 3, these two parts being separated by a base 12 of the tooth holder 2.
- the sole 4 is a wear sole having rectangular lower and upper faces and having a convex longitudinal profile. When the sole 4 is new, its thickness is constant along its longitudinal profile.
- the width of the sole 4 defines the compacting width of the tool 1. As this width is generally smaller than the length of the sole 4, a rectangular imprint is obtained on the compacted soil. It is by juxtaposition of several tools 1 of such a moderate width that it will be possible to compact large areas.
- the sole 4 is engaged on the lower surface of the tooth carrier 2, abutting between the heel 11 of the tooth carrier 2 and a base 12 carrying the projecting portion 7 of the tooth carrier 2.
- the lower surface of the carrier tooth 2 is itself convex, so as to have a complementary profile to the sole 4.
- the attachment between the sole 4 and the tooth holder 2 is provided by keys 19 which engage in openings 13,14 formed respectively in the sole 4 and in the toothed carrier 2.
- the sole 4 is preferably made of steel, possibly reinforced with tungsten carbide parts, and can be cast or forged.
- the compaction tool is rotated along an axis parallel to the surface to be compacted.
- the tool can be mounted on the branch of a star 32 of a rotor 31, as shown in Figures 1 and 2.
- the axis of rotation of the tool is symbolized in these Figures by a segment shown above the rotor 31.
- the corner formed by the lower face and the upper face 5 of the tooth 3 can come penetrate superficially into the surface to be compacted and separate a superficial layer.
- the tooth 3 can also simply slide by its underside on the surface to be compacted, without detaching material.
- the compaction tool 1 is moved in translation. This movement is obtained for example by mounting the tool 1 on a dedicated mobile machine such as a truck, a tractor or a digger or a gear designed specifically for the tool.
- a dedicated mobile machine such as a truck, a tractor or a digger or a gear designed specifically for the tool.
- the speed of rotation of the tool will be adjusted to its speed of translation, so that these two speeds are proportional to one another.
- an acceleration of the speed of the machine will cause an acceleration of the rotation of the tool 1, to maintain a regular and uniform compaction as the vehicle moves.
- Both speeds will be preferably adjusted so that the speed of rotation at the periphery of the compaction tool is always greater than or equal to the speed of translation.
- the rotational speed at the periphery of the compacting tool is greater than the translational speed
- the compacting tool 1 passes several times vertically to the same point of the surface to be compacted, which allows obtain a continuous trace of the sole in the surface to be compacted.
- the particular case in which the rotational speed at the periphery of the tool 1 is equal to its translational speed can be conceived in particular to embed chippings brought to the ground. In this case, the same tool only passes once under the same point.
- the translational pitch p which is the offset distance of the tool in a rotation cycle, that is to say between two successive passages in the same direction of rotation at a given height, for example at the height of the rotor axis.
- the pitch is itself a function of the speed of translation of the machine and the speed of rotation of the rotor.
- the tool When the tool is rotated while following a translation movement driven by a machine carrier, it makes successive passes vertically above the surface to be compacted, each passage being offset from the previous passage according to the translation pitch p. If we consider the successive passages n and n + 1 of the tool on the surface to be compacted, we can establish a relationship between the process parameters given above and the height of material engaged under the sole of the tool .
- the height H of material engaged under the sole is defined by the intersection of the cylinder described by the heel of the sole at passage n and the cylinder described by the edge of the tooth at passage n + 1.
- this height H is thus defined by the intersection of the circles defined by the equations (1) and (2) (origin of the axes placed in the center of the rotor with the passage n):
- a total or partial servo system can therefore continuously adjust the speed of translation of the carrier, the rotational speed of the rotor and / or the position of the compaction tool to optimize the number of passes required for compaction. effective.
- FIG 3 there is shown a schematic view of a compacting tool 1 according to the embodiment shown in Figures 1 and 2.
- the sole 4 of this type of compaction tool 1 will be preferably made of forged steel.
- the sole 4 is new and has a constant thickness along its length. It should be noted, however, that due to the configuration of the compaction tool 1, the sole 4 undergoes more wear at its heel than at its front. Indeed, the heel is the part of the sole 4 which has the most important support on the surface to be compacted and is subject in return to the most important constraints. For this reason, the thickness of the heel of the sole 4 is brought to decrease faster than that of its front part.
- the outsole system according to the invention offers the possibility of returning a worn sole 4 to extend its life, placing the most worn part at the front of the sole 4.
- Figure 4 shows a compaction tool 1 according to another embodiment.
- the sole 4 ' is fixed thereto by a system of studs 15 which protrude from the upper surface of the sole 4' and come to fit into complementary shaped mortises provided in the lower surface of the tooth holder 2.
- the tenons are maintained by keyways that fit into openings 16 provided in the lateral faces of the tooth carrier 2 and tenons 15.
- This type of sole 4 ' is preferably made of cast steel.
- FIGS 5-7 show particular embodiments of the flanges 4, 4 '.
- the sole 4 is reinforced by transverse bars 17, made of a material of high strength, such as tungsten carbide. It is advantageous to provide a bar 17 'heel wider than the other bars, for example 2 to 3 cm, this part of the sole 4 being subjected to greater wear than the rest of the sole 4.
- the lower surface of the sole 4 ' has longitudinal ribs 20. These allow texturing of the soil during compaction, thus making it more rough. It is thus possible to make a hook layer which will have better bonding properties with the upper layer. The final pavement will therefore have a better deformation behavior, the different layers being better joined together.
- the sole 4 is provided with spikes 18 made of a high strength material such as tungsten carbide. These tips 18 are inserted into the thickness of the sole 4, and protrude from the lower surface thereof with a projecting end. This end allows them to texturize the soil during compaction, to make it more rough.
- the sole may comprise several rows of points 18. These are preferably arranged in staggered rows, that is to say each row laterally offset. compared to the neighboring row. The tips are preferably placed at the heel of the sole 4.
- FIG. 8a there is shown a cross section of a compaction module 30 in sectional view. It comprises a hollow cylindrical rotor 31 carrying at its periphery several compaction tools 1. As shown in this Figure, the same cross section of the rotor 31 comprises several compacting tools 1 (in the case shown, three compaction tools 1). Each compacting tool 1 is connected to the periphery of the rotor 31 by a connecting star 32. The paths traveled respectively by the tooth 3 of a tool 1 and by the back of the sole 4 of a tool 1 are shown in dashed lines and show the eccentricity e of the compacting tools 1.
- the convexity of the sole 4 is defined in relation to the radius of rotation of the compacting tool 1 carried by the rotor 31 so that the sole 4 is developed outside the cylinder of revolution described by the leading edge. of the compacting tool 1 during rotation.
- the eccentricity e is therefore positive.
- FIG. 8b there is shown a projected view, on a flat surface, of a compaction module 30 'made according to another embodiment of the invention.
- the module of Figure 8b consists of a cylindrical rotor 31, which has been shown the peripheral surface in a projected view, rotor 31 on which are mounted a plurality of compaction tools 1.
- the tools 1 are both distributed along the axis of the rotor 31, and according to its circumference.
- each cross section of the rotor 31 comprises two compacting tools 1.
- the tools 1 are offset laterally to one another, with no lateral space between them or with minimal overlap so as to cover the compacting surface without discontinuity.
- FIG. 9a shows a compaction module 30 '' according to another embodiment.
- the module 30 "consists of a hollow cylindrical rotor 31 mounted on a shaft 41 rotated by a motor, such as a hydraulic motor 40, shown schematically in this Figure.
- the assembly is connected, via a backplate system 61, to an articulated arm 60 connected to a carrier not shown, the arm 60 is also shown schematically.
- the rotor 31 carries several compaction tools 1, connected to the rotor 31 by connecting stars 32.
- the compacting tools 1 are offset relative to each other along the axis of the drum 31, each tool 1 being disposed laterally to its neighbor, with no lateral space between them or with a minimal overlap, so that all the 1 covers continuously the width of the rotor 31.
- each tool 1 can be changed independently of the other tools 1.
- the compaction tools 1 are also offset relative to each other according to the circumference of the drum.
