Definitions

  • the present invention relates to a soil marking process, more particularly intended for stabilized or turfed land. It also relates to machines used in the implementation of the method.
  • the marking thus produced has the disadvantages of having to be repeated practically before each event, of being very sensitive to climatic conditions such as rain and wind, and of becoming very approximate during a match, under the effect of the only trampling. , with the consequence of making arbitration difficult and subject to discussion.
  • the present invention aims to overcome these drawbacks by means of a new marking process, while also respecting a certain number of requirements, in particular with the aim of preserving the safety of the players.
  • a marking element must in no case be tripped over for athletes. It must also have a flexibility as close as possible to that of the ground so as not to be hurtful in the event of a fall.
  • its surface characteristics in particular its adhesion characteristics, are such that the players do not feel differences in the search for their supports (for example, it is not admissible that the marking be slippery) .
  • the marking should not obstruct the flow of water parallel to the surface, as otherwise it could result in the formation of pits and puddles on each side of the strips.
  • the method according to the invention which provides a satisfactory response to these different conditions is characterized in that it consists in filling a previously dug cavity, the shape of which corresponds substantially to that of the layout to be made, with an aggregate consisting of rubber in small pieces and a binder retaining a flexible state, the aggregate being formed in such a way that at least most of the pieces of rubber are only partially coated; and painting the desired marking on the surface of said aggregate.
  • said cavity is generally a trench, to carry out all that is linear marking, or a circular hole for the representation of points.
  • the rubber pieces on the periphery of the aggregate form an irregular surface, the reliefs or asperities of which constitute anchoring points in the walls of the cavity. On the surface, the roughness makes the marking non-slip, even in the rain.
  • the fact of dosing the quantity of binder so that the greatest number of the pieces of rubber are not completely drowned ensures the reservation of gaps. These give the aggregate good water permeability, so that the marking strips are not interrupted by the flow parallel to the surface. The presence of gaps also contributes to the flexibility of the aggregate.
  • bitumen As a binder, it is advantageous to use bitumen or derived products. Bitumen has the advantage of being cheap and relatively easy to work. By pouring it at a temperature of the order from 100 to 120 ° C, its viscosity is satisfactory for the reservation of said interstices.
  • bitumen Under normal temperature conditions, the bitumen remains relatively soft, so that the aggregate benefits from the elasticity (compressibility and shape memory) of the rubber. In addition, to match the flexibility characteristics of the aggregate to those of the ground, it is easy to modify the degree of hardening of the bitumen by adding sand.
  • the addition of sand is also useful for two other reasons. On the one hand, it helps prevent bitumen from becoming too liquid again in sunny and hot weather. On the other hand, it increases the ability to crumble the aggregate, necessary so that it is not dangerous: a player performing a slide with a spiked shoe should not feel shock when crossing a marking strip. The ability to crumble also proves to be advantageous in the event of land renovation: the work can be done without prior removal of the marking aggregate which, under the action of agricultural machinery, behaves like soil and is simply finds it scattered and mixed with it.
  • the formation of the aggregate in the cavity is carried out in several stages as follows: the cavity is first partially filled with rubber in pieces, for example halfway , then bitumen is poured in metered quantity and under temperature conditions as defined above for the reservation of interstices, without covering the surface pieces. The same process is then repeated to completely fill the cavity. In practice, this generally has a depth of 3 to 4 cm, approximately. As for the width of the trenches for the realization of linear markings, preferably, it is around 12 cm, a little larger than the width of the marking itself. This way of operating in several stages makes it possible to obtain a homogeneous aggregate, because in each phase, the descent of the bitumen to reach the lower rubber pieces is minimal and that, consequently, during this descent, the temperature of the bitumen does not vary significantly.
  • the rubber-bitumen mixture is first produced, then it is applied in the cavity while the bitumen is still hot.
  • This solution has the advantage of requiring only a single operation for filling the cavity with the aggregate.
  • a machine specially designed to carry out the process in the manner just described comprises, on a chassis mounted on wheels, a first container for the rubber in pieces, a second container for the binder, a conveying means starting from the base of the first container, an outlet for the binder above said conveying means, outside the first container, said outlet being provided with a stop and flow adjustment means, and, connected to the outlet conveying means, a means of supplying the rubber-binder mixture into the cavity to be filled.
  • the machine frame mounted on wheels 1, carries a container or hopper 2 for the rubber pieces C, at the bottom of which, in a groove 3 oriented longitudinally, is housed an endless screw 4 driven by a motor 5.
  • the groove 3 is extended outside the hopper 2 by a channel 3 ′ in which the worm screw 4 also extends.
  • a conduit 6 which is bent to open out towards the bottom.
  • at least part of the conduit 6 is flexible, so that one can, in operation, place its outlet end inside the trench 7 to be filled.
  • the outlet of the conduit 6 is oblique with respect to its axis.
  • a tank 8 intended to receive hot bitumen B is attached to the hopper 8, above the channel 3 ′. At its base, it is in communication with a conduit 9, the outlet end of which is located above the channel 3 ′, which, at least in this zone, is uncovered. On the other hand, on the conduit 9, there is provided a stop valve 10 and adjusting the bitumen flow rate.
  • the machine previously loaded with pieces of rubber C and hot bitumen B is disposed above the trench 7 to be filled, the outlet end of the conduit 6 being placed inside the latter.
  • the conveying of pieces of rubber C is then initialized from the hopper 2 by starting the motor 5, for example an electric motor.
  • the tap 10 is opened to produce a flow of bitumen B on the rubber transported by the screw 4.
  • the flow of bitumen is r / gle in such a way that it is just sufficient to agglomerate the pieces of rubber together, only partially coating them.
  • the agglomerate obtained, when it enters and passes through line 6, has a pasty consistency due to the fact that the temperature of the bitumen remains high, so that at the outlet in the cavity to be filled, it spreads therein. ensuring a correct filling.
  • the filling height is determined by the speed of movement of the machine.
  • the machine can be designed light enough to be moved manually.
  • a more elaborate machine, with motorized drive may include additional means such as heating means to bring and / or maintain the bitumen at the temperature of use.
  • additional means such as heating means to bring and / or maintain the bitumen at the temperature of use.
  • the rubber used to implement the process of the invention is recovered in tire retreading units: it comes from the used tire tread, which is removed prior to retreading by means of machines chipping.
  • the use of said chips as such in the process of the invention proves entirely satisfactory.
  • the marking produced in accordance with the invention has a lifespan of several years, only the paint having to be redone regularly, for example annually. Of course, the marking keeps clear contours and, moreover, it is more visible than the traces which are produced in a conventional manner with plaster or lime.
