Definitions
- the invention relates to a system for draining a ground, in particular sports grounds, sports grounds for tennis, sports halls or green spaces in general as well as the treatment of particular grounds where the cultivation is done in more or less grounds. less humid such as rice fields for example. It also relates to any system implementing such a method, as well as the applications arising therefrom.
- the classic technique consists in making flow trenches crisscrossing the surface of the land to be drained, in which the earth is replaced by a material intended to ensure the flow of water from the topsoil to the appropriate underlying gravel layer.
- Another known technique consists in forcing the filling material into the earth by force to ensure the same function.
- the present invention aims to overcome these drawbacks and relates to a drainage process capable of performing this function without the need to use any slope, for the evacuation of water, this process does not rely on a drainage water drainage by gravity.
- Such a process has the enormous advantage of making it possible to fetch the water to be evacuated, at a very great distance, or, conversely, to distribute it on demand as far as necessary, and this in a homogeneous manner over the entire surface. to irrigate.
- One of the advantages of the invention is therefore, on the one hand, to control water drainage and, on the other hand, irrigation by means which are effective and simple to implement, and which limit work as much as possible.
- Another advantage consists in avoiding, in all points, all risks of untimely sedimentation.
- the present invention relates more precisely to a land drainage method comprising a network of trenches connecting the topsoil to the porous subsoil; it is characterized in that a network of drains, in the form of a perforated pipe in intimate connection with this porous basement, • covering without any solution of continuity all the surface concerned and contained in a single plane, is connected to a pumping station capable of putting this pipe under vacuum to suck, or under pressure to push back.
- FIG. 1 is a schematic illustration of the method and the drainage system of a land, according to the invention
- FIG. 2 is a schematic illustration of the drainage system according to Figure 1, the operation of which is opposite to the previous one, that is to say that it operates in an irrigation system, instead of operating in a drainage system;
- FIG. 3 illustrates an important detail of a system according to the invention
- FIG. 4 schematically illustrates a control operation simplifying maintenance procedures, achievable through the implementation of a system according to the invention
- FIG. 5 shows schematically, in section, an installation implementing a system according to the invention
- FIG. 6 schematically illustrates an application of the method and the system according to the invention.
- FIG. 1 schematically illustrates, seen in section, a drainage method according to the invention.
- the digging is carried out, according to a determined configuration, of a trench 1, which is filled with a porous material such as gravel, responsible for collecting the excess water 70 from the surface 2, from the ground. covered with topsoil 3, and which carries, for example, a lawn 33 to bring it towards the porous layer 5, underlying.
- a porous material such as gravel
- a drain 10 which is in the form of a perforated pipe is brought into intimate contact with the porous layer 5, to collect the excess water.
- this drain 10 is in the form of a perforated pipe whose physical characteristics are such that it supports a vacuum.
- this drain (10) winds in a determined plane over the entire surface to be drained concerned. It has no solution of continuity.
- This pipe is, according to another characteristic of the invention, connected to a pumping station, not shown in Figure 1, but which will be illustrated later. During the vacuuming operation, the water will undergo a forced circulation all along the pipe (10) towards the evacuation without having to be subjected to any action of gravity. The slope, under these conditions, is no longer necessary.
- the pumping of the water will be more or less rapid and its evacuation will depend on it. It is therefore possible, under these conditions, to control the operating conditions of the vacuum pump, as a function of the drainage parameters that have been carefully programmed beforehand.
- a quantity of controlled water is then injected into the drain 10 which runs through the circuit formed by the drain 10.
- this injected water progresses by capillarity through the trenches 1 and towards the topsoil 3 qu 'it irrigates evenly. It suffices to optimize the number and distribution of these trenches to obtain a level of humidification water at planted ground 71.
- Another application also consists in including in this irrigation water, fertilizers, in whatever form, which, through the subsoil will progress towards the surface and feed the roots of plants, lawns or trees which will have then tend to be attracted in depth.
- fertilizers in whatever form, which, through the subsoil will progress towards the surface and feed the roots of plants, lawns or trees which will have then tend to be attracted in depth.
- the water circulation will be according to arrow FI; on the other hand, in the case of FIG. 2, this circulation will be in the direction of the arrow F2.
- the water circulating inside the drains 10 penetrates and thus progresses at a constant speed towards the trench holes 1 (which, in this phase operate as drippers), the water pressure is thus distributed uniformly from the start to 'at the end of the drain 1.
- the roots of the grass are attracted deep which increases their resistance to tearing and allows them to draw mineral salts in depth.
- the leaching of fertilizers, especially nitrogen is avoided.
- a single pipe (10) is positioned in a determined plane, relative to the surface of the ground. It follows that the drainage of water as well as humidification or irrigation, or even when necessary, with water loaded with fertilizer, will be carried out in a homogeneous manner without any intervention of gravity. for drainage or elsewhere the need to overcome this gravity for irrigation.
- the water injected into the circuit will be heated and, in turn, will ensure that the soil stays frost-free, which is not without interest, especially when the climatic conditions are detrimental to the proper functioning of the sports facilities. in particular, concerned.
- maintenance outlets 30 are provided on the drainage circuit, at regular intervals . Visual or automatic checks are, under these conditions, entirely possible and do not pose any operating problem. These inspection manholes are spaced, for example, 150 m from each other.
- the user can introduce inside the drain 10, which is none other than the perforated pipe supporting a vacuum, or under pressure a control member 60, capable of visualizing what is happening inside this drain 10. It may be, in particular, an endoscope of the fiber optic type currently available on the market. In the example described, this is a football field where a player 61 plays with the ball 63, while the employee checks with an endoscope 60.
- FIG. 5 and 6 show, respectively, seen in section and in plan an application of the present invention.
- This is by way of nonlimiting example of a sports field and more particularly of a play area 111 surrounded by a track 120.
- a sports field comprises the combination of a network of trenches 1, furrowed in the transverse direction by a drain 10, in a given plane and parallel to the ground surface, leading to a connection connected to a pumping group 101, capable at the same time, of ensuring a suction function (evacuation) or discharge (pressurized water).
- FIG. 6 shows a football field 111, with its classic boundaries of the playing areas (goal 110, and midfielder, as well
- the pumping station 101 comprising its vacuum and discharge pump 80, and an evacuation outlet 90, which during a drought phase becomes a source of water or fertilizer supply. or water / fertilizer mixture.
- the pumping station 101 comprising its vacuum and discharge pump 80, and an evacuation outlet 90, which during a drought phase becomes a source of water or fertilizer supply. or water / fertilizer mixture.
- this system essentially consists of a buried network maintained under permanent vacuum which ensures the transport of drainage water.
- the vacuum system receives the water and can easily discharge it into a main sewer. It can also discharge it into a reservoir from which we can draw for a possible irrigation phase.
- one of the applications of the invention is in the technique of rice field exploitation. It is indeed possible, thanks to the implementation of the present invention to pump water from a site, at a certain level, to lead it to another level and vice versa, which, in the case rice cultivation can significantly increase the yield.
- a simple system of valves allows the loading of the flow trenches which then become supply trenches by capillarity.
- the present invention applies to the drainage and irrigation of any green space, for pleasure and for sport, - vegetable crops, greenhouses, without forgetting all the applications relating to crops. performing in humid environments but, the humidification rate of which must be strictly controlled.
