Description

METHOD AND DEVICE FOR A TERM MANAGEMENT AQUATIQ

WHITE WATER

DESCRIPTION FIELD OF INVENTION 5 The invention relates to activities and water sports, as the canoe and Kayak, which is used for rivers where water stadiums are built to allow the training of practitioners and conduct of competitions. 0 ART

The practice of water sports, particularly canoeing and kayaking, is in constant evolution and growth. To this end, several types of water courses are used. 5 The first type consists of natural rivers that offer a privileged 'to practitioners and require very little amenities such as tags hanging above the river e entuellement 0 schematize a determined route in bed this r st.

A second type of water course is offered by pseudo rangelands that are a énagements rivers using natural riprap or concrete. Indeed, the river bed 5 is modified by creating artificial volumes by means of concrete masses installed in the river bed.

A third type of aquatic course is constituted by artificial streams obtained, 0 for example, by diverting a part of the flow of a river in an artificial channel or pump. These types of water courses will offer, for a specific river, a single flow of water from the river, determined and immovable.

In other words, the bed and the flow of the river is permanently frozen.

In addition, the development of these water activities is such that the white water stadiums are essential drivers and necessary for the practice of these sports, and especially for the canoeing and Kayaking.

The purpose of the invention is to develop a nautical route avoiding the aforementioned drawbacks and can provide the opportunity to change the course of the flow of the river, so as to diversify the possible paths to practice on this river, while not change the The river bed. SUMMARY OF THE INVENTION

To this end, a first main object of the invention is a development process of a boating whitewater course, designed for water activities, and of changing the bed of the river, which must be put out of water, creating artificial volumes in the bed of the river. According to the invention, it is to proceed by the following steps:

- to partially out of water the river;

- disposing on the river bed at each location where it is desired to create a volume, at least one base provided with holes opening on its upper surface; - placing in the hole or bases, elements each having a portion projecting from hole to constitute said artificial volumes; and - back in the river water, to thereby create a temporary water course.

An improvement to this method consists è interconnecting several vertical members by a connecting member for securing them and materialize the most important artificial volumes.

It is also possible to link together elements by an inter ediate board thereby increasing the artificial volumes created by these E LEMENTS.

The second main object of the invention is a device for the construction of a water course in white water, especially for water sports by changing the bed of a river including:

- pedestals to lay on the bed of the river; and

- elements fixed to the bases and having one voluminous upper portion to constitute a portion of the artificial volumes in the river bed.

The bases which can be made of concrete are preferably provided with holes on the upper surface of the base and the elements each have a rod to ensure their fixation in the holes.

In this case, the holes are through holes and vertical with respect to the bases.

In this embodiment, the bases are each a few feet so that these bases are raised above the river bed to cause traffic around and through the pedestals to clean the holes. The upper portion of certain elements may be constituted by a polyethylene casing molded around the rod which extends over the entire height of the Electrolighting lies or a vertical cylinder the base of which is fi ed to the lower stem means of a concrete sleeve.

One can thus choose the path that it is desired to install by placing first. Concrete pedestals in some places and by equipping them with one or more vertical members.

A preferred embodiment of the invention provides that the elements each consist of a vertical cylinder itself constituting the upper part to the base of which is secured the lower rod by means of a concrete sleeve.

advantageously complete such cylinders practicing handling openings in the wall of each of them and also allowing the water of the river from entering the cylinder during the topping up the river and to evacuate the cylinder during the retirement of river water.

In this embodiment, each vertical member may complete a round cover provided with at least one hole. One can also use multiple lids consist of several rounds each provided with at least one hole to put on the top of several ad acents cylinders. This creates larger volumes. The cylinders and the lids may be either polyvinyl chloride or polyethylene. Preferably, the bases of the holes are covered with a preferably metallic sheath.

Preferably, the sleeve has on its inner surface grooves. Similarly, the rods have grooves longi studied na The.

An improvement of the invention consists in that the upper portions of certain elements have grooves to accommodate inter ediate boards placed between two elements and thus increasing the artificial volumes created by the E LEMENTS. LIST OF FIGURES

L * i nvention and its technical charac stics will be better understood on reading the detailed description of a sheave Li sati one of the invention, which follows and which is appended figures representing respectively: Figure 1, in section, a first embodiment of an element and a device of the base according to the i nventi on;

- Figure 2, in front view, an assembly of a plurality of vertical elements constituting a determined volume; - Figure 3, a top view corresponding to Figure 2; 4, a second embodiment of an element of the device according to the invention; and 5, in top view, uti lisation of elements of Figure 4. DETAILED DESCRIPTION OF CARRYING OUT THE INVENTION

The method and device are simultaneously described in this specification. Referring to Figure 1, the first main part of the device according to the invention is to create a series of bases 1, preferably concrete, and intended to be laid on the floor of the river bed, that is to -dire the bottom of it. The main feature of these bases is one that can be set above the elements 10 which are to constitute the artificial volumes. As shown in the embodiment described, this is possible in that the bases 1 each have a series of holes 2, for example, vertical and the through, on the upper surface 3 of the base 1 in question. The fact that these holes are through-2 prevents the suction effect when introducing or withdrawing an object of these holes 2. They are preferably reinforced with a sleeve which can for example be metal 4 to increase their resistance wear and ensure stability volumes ficiels art created in the river.

It is also preferable to provide 22 feet below pedestals 1 so as to raise them. Indeed, if they are surrounded by water. The current can allow a systematic cleaning of the holes 2 When the through. One can thus consider using 1 pedestals whose sides can vary, for example, from one to three meters. Given that these pedestals 1 are preferably made of concrete, the handling thereof shall be made by means of a crane. The second essential element of the device according to the invention consists of an element of Lot 10, for example, vertical, which are intended to form a volume in the artificial river bed and to divert the flow of water of the latter. To be set in a concrete base 1, the embodiment shown provides that each member has in its lower part a fastening rod 11, whose shape corresponds to the inner diameter of the sleeve 4. It is pointed out here that, not only the shape complementary to the inner shape of the sheath 4 (a cylindrical tube if the sleeve 4 is cylindrical) can be used, but also all forms included can be. Thus, considering the use of attachment rods 11 in cylindrical sleeves 4 whose inner shape is circular in which is inscribed the outer surface of the rods. In a first embodiment, and to faci liter handling of this upright member 10, the lower rod 11 may advantageously be designed as a metallic hollow profile profi. It is fixed to an upper portion 12 of the vertical member 10 which is large. Indeed, it is the operational part vis-à-vis the flow of the river to change. The fixing of the lower rod 11 to the upper part voluminous 12 can advantageously using any concrete bond constituting an attachment sleeve 13. It is thus understood that it is possible not only to equip n 'any base 1 of one or more vertical members 10 to form an artificial barrier in the bed of the river, but that l is also possible to place this artificial impediment to a desired location by placing the base 1 at the location correspondent on the bottom of the river.

With reference to Figures 2 and 3, we see immediately that the device of the invention allows any kind of form of artificial barriers in the bed of the river, as long as the installation bases is 1 possible on the bottom of it. Indeed, Figure 2 shows four vertical elements 10 placed next to one another. Indeed, it is preferably provided that the center distance of the holes 2 1 pedestals corresponds to the diameter or width of the vertical members 10. In this way, the latter being placed adjacent, can play the role of a dam vis-à-vis the water of the river.

Figure 3 shows a top view of a possible embodiment of an obstacle represented by Figure 2. In fact, considering the edge 20 of the river, we see that the installation of one or more bases on the side of the bed near the edge 20 allows to build advanced 21 consists of eight vertical members 10 placed so as to obtain the desired shape. This creates a diversion of the flow of the river, that is to say an aid climbing rotating sky.

The embodiment of Figure 3 shows that the holes 4 are placed staggered relative to the edges 20 of the riverbed. This is only one example embodiment, the pedestals can be arranged anyhow on the bottom of the river, like the location of the holes 2 in these bases 1 may be provided in any geometry. It is still better than their position and distance allow to form compact volumes. It is also understood that if one or more pedestals 1 are placed in the middle of the river, it is possible to create not only a forward edge 20 of the river, but an artificial island in mid place the bed of the latter.

Returning to Figure 1, for the handling of vertical members 10, is provided to perform at least one handling hole 14 in the wall of the upper portion 12 of the vertical members 10. It is also advantageous that the holes 14 have a shaped handle. It is thus possible to manually place the vertical elements 10 in the holes 2 of the bases 1 the desired locations. It should also specify here that the invention preferably applies to rivers that can be made at least partially out of water, that is to say can be dewatered in large part. Once the installation of vertical elements 10 performed, the river may be called into water. Handling The holes 14 allow then to the vertical members 10 to stay in the bases 1 and not float. Indeed, these mounting holes 14 allow water to enter progressi ly in each of the vertical elements. The achievement of lower rods 11 by means of hollow profiles allows a possible flow of water from the inside of the vertical members 10 below the bases 1, if the holes 2 not 1 0

lead not tightly on the bottom 5 of the river. Finally, it is advantageous to provide a drain hole 19 in the bottom of the cylinder 12 to allow water to flow out of the upper portion 12 5 at a setting out of water of the river, before any displacement of the vertical member. This type of hole 19 can also serve as handling hole, from the moment that he has form. A first embodiment 10 pref-competitive of the upper part 12 of the vertical members 10 is to use relatively large cylinders. It is believed particularly to PVC sewerage pipes, that is to say, polyvinyl chloride or polyethylene 15.

These upright members 10 are preferably each filled with a round cover 15 placed at the top 16 of a vertical member 10. Such a cover is mainly used to avoid the 20 users water course to jam a ambe or an arm in one of el vertical elements 10 is preferably provided at least a hole 17 passing through each of the lids 16, to allow air to escape during the gradual filling 25 within the vertical members 10 during the topping up River.

In the case illustrated in Figures 2 and 3, it is advantageous to have a connecting part as a multiple cap 18 consists of 30 individual round lids secured to each other. Such multiple cap 18 serves to stiffen the structure created by several ad acents vertical elements 10. January 1

Single or multiple lids can also be made of the same material as the upper part 12 of the vertical members 10, in this case PVC or polyethylene. The weight of such a vertical element can then be about sixty ki logrammes to a size of about one meter and fifty to two meters. Such vertical members 10 can withstand a share water level difference on either side of the vertical element equal to one meter. It is therefore understandable that it is possible to form local currents faster and deviations of the flow of the river to simulate obstacles and situations of high difficulties on a water course such as fast.

It was clarified that this preferred embodiment of the invention provides that the lower rod 11 of the vertical members 10 is a cylindrical pin and the corresponding holes 2 are also listed. This is only an embodiment, both of which can have different forms, but related.

Similarly, the section of the vertical members 10 may be not cylindrical, but square or more or less appropriate to the configuration of the obstacle which it is desired to create. They may, in particular, have the complementary shape of the river bank next to the place where they are placed to allow an obstacle to be in intimate contact with it and thereby prevent the flow along the riverbank . February 1

Referring to Figure 4, a second embodiment preferen ielle elements mainly consists of molding a synthetic material, such as polyethylene, around a large rod 25 extending the full height of the element.

this then constitutes a vertical member having a casing 2 may have any shape.

This makes it possible to mold a large number of different obstacles in order to obtain a relatively complete set of obstacles to achieve a varied course.

In this figure 4, the rod 25 is shown with longitudinal grooves 28. This may facilitate the introduction of the rods into holes 25, or the sleeve holes, When there is some dirt or sand inside of these. The mounting facility may also be obtained by practicing the grooves on the inner surface of the sleeves placed in the holes. To enable the handling of these elements 10, lower grooves 26 may be provided at the bottom of the polyethylene jacket 23. It can thus accommodate the beads 27 in the upper part of the lower grooves 26 to form gripping handles.

On the other hand, with reference to Figure 5, it is advantageous to practice large Longitudinal grooves 31 over a portion or over the entire height of several elements 10 to an intermediate plate 30 can be inserted therein. It may well be a connection between two elements 10 so as to provide additional opportunities for the formation of various obstacles. Plates 1 3

intermediate 30 may have different heights so as to constitute either a complete barrier vis-à-vis a boat, a sort of weir to cause rapid. ADVANTAGES OF THE INVENTION

The method and the device according to the invention make it possible to have an evolutionary furniture that may be placed not only in running water, but in a simple water. Such white water stadium using this type of barrier offers a range of possibilities waves of variations conducive to users. This type of material makes it possible to overcome certain disadvantages, in a particular place, the riverbed in punctually constituting too difficult transition for users. Conversely, it is possible to create artificial difficulties in the bed of a river that usually does not present major difficulties for Advanced users.

In addition, the barriers are moveable, and for varying currents and movements of water from the same river in the same locale t. In addition, elements of the device can be easily standardized. vertical elements 10 of the height that is accurate but can be highly variable, depending on the water level of the river or the type of obstacle that is to be created.

Aquatic path thus created may possibly be accessible to practitioners of all levels, lorsqu'i ls are associated with variations in flow of the river. Finally, through its removable character, the invention removes the river all the items after use, so as to restore the river to its original natural bed. But it must be said to conclude that the invention is particularly well adapted to artificial river arms that were built previously, such as bypass any design installed on or along the ri st, such as a barrage.

Other embodiments are possible, the concept of the invention lies in the fact to set items on pedestals placed at the bottom of the river to convert.
