Definitions
- the present invention relates to a stabilized ground, in particular for the practice of tennis, and its method of manufacture.
- the invention also relates to a method of renovating existing stabilized land.
- the stabilized ground comprises a support structured textile forming an open-structure carpet made of fibers synthetic rot.
- the textile support is loaded successively a layer of sand then a layer of crushed brick.
- the sand layer whose height is slightly less than the height of the support fibers textile, has a grain size ensuring proper drainage.
- Layer crushed brick which has a particle size smaller than the particle size of the layer of sand, is arranged to fill the gap remaining in the surface of the textile support.
- the "French Court” offers a playing comfort equivalent to that of a tennis court. traditional clay tennis. But such a stabilized ground requires a followed and is relatively fragile. Indeed, it is necessary to water the crushed brick to prevent it being driven by the wind, and it is necessary to also make a steady supply of crushed brick and brush the ground frequently. Moreover, during hot weather, the crushed brick, which must be maintained very wet (intense watering), undergoes in these conditions an annealing. The crushed brick therefore tends to harden, making the ground impermeable.
- the object of the present invention is to propose a stabilized ground, in particular for the practice of tennis, which does not have the disadvantages mentioned above. According to the invention, this objective is achieved by a stabilized ground according to claim 1.
- a stabilized ground according to the invention comprises a base surface to which are fixed essentially vertical fibers so as to form a Carpet type support.
- a lower layer of granular material rests on the base surface and is distributed between the fibers, the height of this layer lower than the fibers.
- an upper layer consisting essentially of crushed rock rests on the lower layer. The height of the rock top layer crushed is such that its upper surface is at a level higher than that from the upper end of the fibers.
- the surface of the stabilized ground that is to say the upper surface of the crushed rock top layer is at above the fibers.
- the carpet formed by the fiber base surface constitutes a reinforcement for the lower part of the upper layer, allowing the stabilization and drainage.
- the crushed rock has a mass specificity superior to that of the crushed brick as well as a greater hardness.
- the main regular maintenance required by the stabilized ground according to the invention is the passage of a net to drag. Over time, the rock crushed degrades much less quickly than crushed brick and the ground retains then an upper layer with good porosity. The land is therefore quickly passable after heavy rains and is not likely to be destroyed by the freeze.
- the stabilized ground according to the invention offers a surface quality, which allows the practice of tennis, as well as sports such as as football, baseball, athletics, or others.
- the terrain will have an area adapted to its use, and regulatory play lines must be installed.
- the present terrain can even be shaped tape, possibly sinuous, to serve for example access path in a private property.
- the stabilized ground according to the invention is practicable all the time and all the year, it can also be adapted to the environment in which it must be integrated. Indeed, unlike crushed brick, the colors of the crushed rock varies according to its origin, which makes it possible to color adapted to its environment. For example, we can use a Rock with a green appearance to make a stabilized ground in a park. It will also be appreciated that it is possible to use a crushed rock of light color for better brightness, thus improving the conditions of play at dusk.
- the crushed rock is a hard rock, such as for example the sandstone, or some other hard rock that does not deteriorate with frost.
- the rock crushed of the upper layer advantageously has a grain size distribution between 0 and 2 mm. This gives a good compromise between surface quality and the porosity of the upper layer.
- the crushed rock top layer will comprise a mixture of grains of grain size varying in the range of 0 to 2 mm, with a majority of grains having a particle size between 0 and 1 mm.
- the proportion of crushed rock having a particle size between 0 and 0.2 mm should preferably be less than 20%.
- the height of the upper layer is such that its upper surface is between 0.5 and 1.5 cm above the upper end of the fibers, preferably 1 cm.
- the upper layer may have a basis weight of between 14 and 20 kg / m 2 , preferably 16 kg / m 2 .
- the lower layer is essentially consisting of sand whose particle size is chosen so that the lower layer has a porosity greater than that of the layer upper crushed rock. It will be ensured here that the granulometry is regular and precise, to limit the proportion of fines and thus ensure good drainage.
- the crushed rock has a continuous grain size between 0 and 2 mm, preferably uses a sand with a particle size of the order of 1 to 1.5 mm.
- the lower layer is essentially consisting of a first sub-layer of sand with a particle size of 1 to 1.5 mm, based on the base area, and a second sub-layer of sand having a particle size of 0.5 to 1 mm, based on the first underlayer.
- the first underlayer allows a good penetration into the carpet and the second underlay forms a good base for the top layer.
- the second underlayer could alternatively be crushed rock with a particle size of 1 at 1.5 mm.
- the lower layer is constituted essentially crushed rock whose particle size is chosen in such a way that the lower layer has a porosity greater than that of the layer upper crushed rock.
- the lower layer we will use preferably crushed rock with a particle size between 1 and 2 mm.
- the base surface and the fibers forming the carpet-type support are preferably of synthetic material.
- the fibers of the carpet have advantageously a height of between 10 and 25 mm, preferably between 20 and 23 mm, to ensure good vertical stability.
- the base area is advantageously permeable to allow a direct flow of water crossing the terrain to an underlying drainage structure.
- the height of the lower layer represents between 80% and 90% of the height of the fibers.
- the carpet fibers have a height between 4 and 12 mm, preferably 6 mm.
- the lower and upper layers can then be formed with crushed rock of the same granulometry, for example in the range of 0 to 2 mm. Such a terrain offers good playing skills for a modest performance cost.
- a manufacturing method is proposed of a stabilized ground according to claim 16, in particular for the practice of tennis, in which we set up a carpet type support on a bottom structure, the support carpet type being formed by a base surface to which are attached essentially vertical fibers. Then, one forms on the base surface a lower layer of granular material distributed between the fibers, the height of the lower layer being lower than that of the fibers. It will be appreciated that one then forms on the lower layer an upper layer constituted essentially of crushed rock, the height of the upper layer being such its upper surface is at a level higher than that of the end superior fiber.
- the present method therefore makes it possible to easily make a stabilized ground practicable at all times and requiring very little maintenance.
- the structure of background that is to say the structure that carries the carpet type support, preferably draining properties, which allows to directly eliminate the water that flows through the field when the base surface is permeable.
- Such a background structure comprises for example a so-called resorbent layer with Absorbent properties, on which the carpet rests. Riprap, placed under the resorbant, allows to evacuate the moisture of the resorbant.
- the present method of manufacture allows also the manufacture of a stabilized ground on a bottom structure in concrete, including a former concrete tennis court.
- the carpet is placed on the existing concrete surface, which will have been preferably flattened and regenerated. It is thus possible to transform a hard and worn tennis court in a stabilized ground presenting a great comfort of play.
- a renovation method is proposed.
- a stabilized tennis court which comprises a carpet-like support formed by a base surface to which are fixed essentially vertical fibers, the carpet type support having a bottom layer of granular material resting on the surface base and having a height less than the height of the fibers.
- the present method of renovation thus allows to restore various stabilized soils of the sandblasted synthetic turf type, such as for example the "French Court".
- the top layer of crushed rock is thick and is essentially formed on the fiber, it is possible to eliminate spot flatness (holes in the carpet) or extending over the entire surface of the land to renovate (unevenness of the bottom structure).
- Fig.1 shows in perspective a stabilized ground 10 according to the present invention, converted into a tennis court.
- the surface of the ground 12 is marked by game lines 14 which delimit the playing surfaces in "simple” and “double”.
- a net 16 held by posts 18 separates the court in a known manner.
- Fig.2 a partial sectional view of the land.
- the carpet-type support 20 is formed by a surface of base 24, consisting of a cloth support impregnated with a layer of latex, to which are fixed by conventional fiber tufting techniques 26 essentially vertical.
- the fibers 26, with a height of 20 mm can be for example polypropylene or polyamide.
- the base area 24 is perforated to provide adequate drainage.
- Stabilized ground 10 includes a lower layer 28, resting on the base surface 24, essentially consisting of sand with a particle size of 1 to 1.5 mm. The height of this lower layer 28 is 17 mm, that is to say that its height is less than that of the fibers 26.
- an upper layer 30 of crushed rock preferably having a continuous particle size of 0 to 2 mm.
- This upper layer 30 has a thickness of 1 cm. It covers the upper ends of the fibers 26, that is to say the last 3 millimeters, and forms an overlay over the 20.
- the playing surface 12 of the stabilized ground 10 is therefore formed by the upper surface of the upper layer 30, and is therefore a level higher than that of fibers 26.
- the playing comfort offered by the stabilized ground 10 according to the invention is equivalent to that of a traditional tennis court, protecting muscles and joints.
- the ball bouncing qualities are excellent and the Playground 12 is fast.
