Definitions
- the invention relates to a submersible device comprising a screen having a plurality of openings, means for holding a first end of said screen on the ground and means for maintaining the height of a second end of said screen.
- Such devices are commonly used in particular in systems for protecting shorelines, and in particular beaches, against an erosion phenomenon, beach sand tending to be driven offshore by the force of the marine current.
- a screen in maximum deployment configuration will offer the current maximum power, causing the generation of a tensile force of an amplitude such that the screen risk of being torn off the means of maintenance on the ground, thus rendering the device irreparably ineffective.
- the invention provides a solution that does not have the disadvantages described above, by proposing a device whose vulnerability to strong currents can be reduced without implementing additional means to the device itself and without the decantation process. triggered by this device is not interrupted.
- the invention relates to a device according to the introductory paragraph, characterized in that the height-keeping means include means for adjusting the height of said second end between a minimum height and a height. Max.
- the invention makes it possible to configure the screen so that it is partially folded, and not completely slumped against the ground. This makes it possible to temporarily reduce the surface opposite to the current, in particular to preserve the physical integrity of the device in the event of a storm, a redeployment of the screen that can easily be made once the storm has passed. Since the height of the screen is adjustable between a low position and a maximum deployment position, the device according to the invention may have a reduced height which will not necessarily be zero as in the known device. This will allow the device according to the invention to continue to cause a settling effect in the folded position, and thus exploit the fact that the water is heavily loaded sediment in case of strong waves to cause accelerated accretion.
- the adjustment means may thus include at least one rope of variable length connecting the second end to at least one buoy.
- the adjustment means may also include at least flotation means adapted to immerse in case of strong swell and connected to the second end by least one fixed or variable length rope.
- the buoyancy means may in particular include one or more buoys dimensioned so that they generate a buoyancy force substantially equivalent to the weight of the screen to which the buoyancy means are connected.
- buoyancy means may include one or more buoys of variable volume, a buoy may further have a tapered shape in the direction of an attachment point of the rope connecting it to the screen.
- the faculty offered by the invention to adjust the deployment height of the screen has other advantages over the known device.
- the adjustment means make it possible to maintain the second end at a sufficiently low height so that the screen is at least partially folded back on itself.
- an opening has a useful surface, which can be conceived as a projection of the contour of this opening on a vertical plane substantially parallel to the first end, which is reduced relative to the actual area occupied by this opening in the opening. screen when fully deployed.
- the screen has in the partially folded position filtering power higher than when fully deployed.
- the screen will tend to unfold and see its orifices open when it will be subject to a certain alternation of the swell, then retract and see its orifices close when it will be subjected to a hollow wave or alternately opposite.
- the device adapts dynamically to the strength of the current to which it is subject, while the known devices behave rather like walls that one day or the other eventually give way.
- the inventor has observed that when the screen is deployed only partially and then does not obstruct the current above the second end, there is a settling and sedimentation effect of each side of the device, which has the effect of accelerating the phenomenon of accretion of the sediments and causes a faster burial of the base of the device having the effect of reinforcing its holding in position.
- an enhancement of the second end allows a new process of settling and sedimentation over the mass of sediment accumulated by the device in its previous configuration.
- the screen is constituted by a multi-filament braided mesh net.
- the mesh of the mesh gives the latter an elasticity which increases the capacity of the screen to dynamically adapt its configuration as a function of the force of the swell.
- each mesh is substantially diamond-shaped defined by four multi-filament strands arranged between nodes forming vertices of said rhombus.
- each mesh In a period of rest, the so-called original shape of each mesh is that of a relatively flat rhombus.
- each mesh receives a traction that stretches its diamond shape to reverse the length ratio between its two diagonals, which stores energy in the strands forming the mesh. Once the wave is passed, by spring effect, the mesh gradually returns to its original shape.
- the invention is particularly interesting for periods of strong swell, the succession of waves having a sinusoidal current distribution that makes the meshes are solicited alternately one after the other, which distributes the traction force over the entire the surface of the screen.
- the four browns which delimit a mesh and which are positioned essentially across the stream in calm weather will, in the presence of a strong current causing a deformation of the diamond, to orient in a direction substantially parallel to that of the current, in the way of the flagging of a crane, allowing a better passage of water and a reduction of turbulence caused by the fibers, which makes such a device more tolerant to strong swells.
- the filaments constituting the net form a very welcoming environment for the constitution of an ecosystem, since in particular the roots of algae and certain molluscs can easily find it.
- a device according to the invention can thus effectively serve as a basis for the generation of an artificial reef look much more natural than those implemented today.
- the ground support means include an anchor chain. This embodiment is advantageous for several reasons: such a device can be loaded onto a boat and be unrolled by means of a drop device as the boat moves forward. The chain will dynamically and naturally marry the geometry of the seabed without any additional manipulation or implementation of fasteners are necessary, while the screen will unfold in a similarly dynamic and natural, so that the device will be operational immediately after being launched.
- the device according to the invention can be removed very simply by connecting the chain to the winch of a boat or barge and winding the chain on a winch capstan, the screen nets which can be simultaneously raised on a net hauler winch.
- the invention thus makes it possible to eliminate, if necessary, any trace of any human intervention on the seabed, which is not possible in the current state of the art.
- the known device requires the implementation also long and dangerous two boats for its only installation, one to unwind the screen, the other to inject a ballast material in a boudin arranged in the lower part of the screen. Moreover, it will be very difficult or impossible to subsequently extract the ballast present in the coil, so that at least this part of the device will remain perpetually placed on the seabed.
- an anchoring chain to form the holding means in position is so advantageous in itself that it can be considered in combination with the device described above, but also with other known screens of the state of the art, and therefore devoid of adjustment means.
- the invention also relates to a system including at least two submersible devices as described above arranged so that the first ends of their respective screens are substantially parallel to each other.
- the second ends of the screens of these two devices can be left free and independent of each other, in which case the system will be particularly well adapted to receive and stabilize large quantities of sand, for example transported and unloaded between screens by a barge.
- the second ends of the screens of at least a first and a second submersible device may also be connected together, so as to form a kind of capital then delimiting an enclosure for amplifying the phenomena of decantation and sedimentation.
- the system may include at least one additional submersible device, disposed between the two other devices and connected by its second end to them, to subdivide the enclosure formed by the capital into at least two chambers, each serving as a settling chamber and sedimentation chamber depending on the direction of the swell.
- additional submersible device disposed between the two other devices and connected by its second end to them, to subdivide the enclosure formed by the capital into at least two chambers, each serving as a settling chamber and sedimentation chamber depending on the direction of the swell.
- the system advantageously includes at least one additional screen whose second end is connected to the screen of one of the first and second devices between its first and second ends.
- This variant makes it possible to subdivide the settling and sedimentation chambers to exponentially amplify the settling and sedimentation phenomena, and thus considerably accelerate the accretion process.
- the second ends of the screens of at least a first and a second submersible device are connected together by an intermediate screen intended to occupy a substantially horizontal position when the system is submerged.
- This other embodiment also makes it possible to create a capital delimiting an enclosure making it possible to amplify the phenomena of settling and sedimentation.
- the system further includes a first plurality of additional screens arranged so that they are substantially parallel to the screen of the first device when the system is submerged, and a second plurality of screens further arranged so that they are substantially parallel to the screen of the second device when the system is submerged.
- This particular embodiment makes it possible to subdivide the enclosure formed by the capital in multiple chambers, each serving as a settling chamber and sedimentation chamber depending on the direction of the swell. Such a subdivision makes it possible to further amplify the phenomena of settling and sedimentation, and thus to accelerate the accretion process.
- the system advantageously includes at least one additional intermediate screen disposed between the first and second ends of the screens of the first and second submersible devices and intended to occupy a substantially horizontal position when the system is submerged.
- This variant makes it possible to multiply by at least two the number of chambers by subdividing them in a substantially vertical direction.
- the additional intermediate screen will advantageously be arranged so as to interconnect intersections between additional screens belonging to the first and second pluralities.
- each cell can alternately serve as a settling chamber and sedimentation.
- the links between screens can be made in various ways, for example by braiding or by shearing.
- a system according to the above description will advantageously include connecting elements having a low tensile strength and intended to ensure at least one connection between screens.
- This embodiment is especially advantageous in that it makes removable portions of the marquee relative to others. Indeed, when a large tensile force will be applied to a screen connected to the rest of the system by means of the aforementioned connecting elements, they will be broken because the anchoring means of the various devices included in the rest of the system keep it in position.

- Figure 12 is a schematic representation of a dismantling process of a protection system according to the invention.
- the general principle of the invention is based on the implementation of means for adjusting the deployment height of a submersible screen for causing a settling and sedimentation effect.
- the invention further provides the use of an anchor chain as a means for holding a submersible screen in position, which is very easy to use with respect to the known position holding means,
- FIG. 1 illustrates a first mode of implementation of the invention which concerns a submersible DSP device, comprising an SCR screen having a plurality of openings, an AM ground-holding means of a first end of said SCR screen, here a low end, and height holding means (FM, C1, C2, C3) of a second end of said screen SCR, here a high end.
- the height-keeping means (FM, C1, C2, C3) include means for adjusting the height of said second end between a minimum height h and a maximum height H.
- the adjustment means include three variable length cables connecting the second end to three buoys forming FM flotation means.
- FIG. 2 represents an erosion protection system that includes three DSP1, DSP2 and DSP3 devices according to the preceding description, connected to the same anchor chain which forms the AM ground holding means of said DSP1 devices, DSP2 and DSP3.
- This anchor chain will preferably have a high density and a strong section, and may advantageously be constituted by a coaster anchor chain having a weight of the order of one hundred kilograms per meter of length, for example between 100. and 300 kgs / m.
- Such a chain will be fixed by its significant weight on any type of bottom, and this from its launching, and its use is particularly advantageous on soft ground where the known fastening means are inoperative.
- the mooring chain is quickly sinking or settling so as to anchor instantly and powerfully the submersible devices to which it is connected.
- additional prevention against any risk of shifting can be achieved by fixing the chain by means of one or more anchors working in longitudinal traction such anchors ANC1 and ANC2 or one or more anchors working in transverse traction such as anchor ANC3.
- Screens SCR1, SCR2 and SCR3 are here made of a material identical to certain fishing nets, in this case a knotted multi-knot rope net, for example polyamide chosen density flowing or floating depending on the use cases.
- Such nets have recognized properties to resist abrasion, to be able to contain heavy loads, and to be remesured, patched, cut and cut at will.
- such nets make it possible to vary the filtering power of the screens SCR1, SCR2 and SCR3 following the stretch to which they are subjected.
- the mesh of the screen SCR1 have a maximum opening area.
- FIG. 3 is a diagram which illustrates the behavior of a protection system according to another embodiment of the invention when it is subjected to a strong swell.
- This system shown here in profile view includes three devices D1, D2 and D3, themselves including screens SC I, SC2 and SC3 whose lower ends are substantially parallel to each other and whose upper ends are connected together to flotation means FMS, which include buoys capable of immersing themselves in the event of heavy swell and connected at the upper ends of screens SCI, SC2 and SC3 by at least one rope. These buoys may for example be dimensioned so that they generate a buoyancy force substantially equivalent to the cumulative weight of screens SCI, SC2 and SC3 to which the FMS flotation means are connected.
- Screens SCI and SC3 form a kind of capital delimiting an enclosure to amplify the phenomena of settling and sedimentation.
- the left part of this figure represents the protection system in substantially symmetrical configuration, in a position where the FMS flotation means are at the surface in a wave trough.
- the upper ends of the screens SC1, SC2 and SC3 are then at a first height denoted ht.
- the right part of the present figure represents the protection system in a deformed configuration, that is to say in a position where the FMS flotation means have immersed while the wave is approaching a maximum.
- the SC1 and SC2 screens are stretched while the screen SC3 is released, the upper ends of the screens SC1, SC2 and SC3 then being at a second height noted ha less than the first height ht.
- the FMS flotation means include buoys capable of immersing thus makes it possible to provide an automatic and dynamic adjustment of the height of the screens SC1, SC2 and SC3 which allows an automatic adaptation of the filtering powers of these screens as a function of the force of the swell.
- FIG. 4 is a diagrammatic perspective view of the advantage obtained by FMSA flotation means including immersible buoys, each of which has a tapered shape in the direction of a rope attachment point; connecting it to the screens described above, which will facilitate the process of affeling said screens.
- the left part of this figure represents the protection system in symmetrical deployment configuration, while the left part of the figure shows the protection system in deformed configuration under the effect of a strong swell, as explained previously.
- This figure makes it possible to compare the shapes of the meshes of the screen SCI in symmetrical deployment configuration and in deformed configuration.
- the meshes of the screen SCI In the symmetrical deployment configuration, the meshes of the screen SCI have a CM1 shape relatively flattened and elongated in the horizontal direction, which gives them an important filtering power, whereas in a deformed configuration, the meshes of the screen SCI present a OMl shape more elongated in the vertical direction, which reduces their filtering power and minimizes the risk of pulling the system by the swell.
- FIG. 5 shows a piece of the SCI screen being stretched.
- the meshes of this screen are such that the large diagonal of the diamond formed by such a mesh is substantially horizontal, which ensures that the opening area of a mesh is relatively small when the net is packed and on the contrary relatively large when the net is stretched, such a net then being able to gradually dampen the swell by deforming.
- lower meshes like the mesh CM are still relatively closed, while upper meshes like the mesh OM are already very open.
- FIG. 6 illustrates an erosion protection system according to a third embodiment of the invention, which includes first, second and third submersible devices D1, D2 and D3 arranged in accordance with the foregoing description, which also includes two additional screens SC4 and SC5 whose upper ends are respectively connected to the screens of the devices D1 and D3 substantially at half height of said screens, which are connected to buoyancy means including buoys B1, B2 and B3, the buoys Blet B3 simultaneously serving as South and North type signal buoys, respectively.
- This variant makes it possible to subdivide the settling and sedimentation chambers delimited by the devices D1 and D2, on the one hand, and D2 and D3, on the other hand, to exponentially amplify the phenomena of settling and sedimentation, and thus of greatly accelerate the accretion process.
- FIG. 7 illustrates an erosion protection system according to a fourth embodiment of the invention, which is similar to the system illustrated in the previous figure, except that the screens of the devices D1 and D3 are produced by means of nets having meshes different from each other.
- the screen of the device D3 is provided with a mesh that is tighter than that of the screen of the device D1, which will facilitate an elastic deformation of the system in the direction of a dominant current CD.
- FIGS. 8 and 9 illustrate an erosion protection system according to a fifth mode of implementation of the invention, which includes five submersible devices whose upper ends are connected together to FM flotation means via an adjusting means the height of said ends.
- FIG. 8 represents this system in a first so-called low configuration, where the adjustment means include a first thread FL1 connecting the upper ends of the devices to the FM flotation means, this first thread having a length 11 such that the height hd high ends of the devices is weak.
- the meshes of the screens are very narrow and there is a fairly rapid accretion to strengthen the ground anchoring of the system.
- FIG. 9 represents this system in a second, so-called high configuration, which has been chosen after a large sediment SDA volume has accumulated in the lower part of the system, in order to guarantee that the system will remain in position when its screens are fully deployed.
- the first wire FL1 previously connecting the high ends of the devices to the FM flotation means has thus been replaced by a second rope having a length 12 such that the height hd2 of the upper ends of the devices is maximum.
- FIG. 10 illustrates a protection system according to a sixth embodiment of the invention, in which the upper ends of the screens SC1 and SC2 of at least a first and a second submersible device are connected together by an intermediate screen SU intended to occupy a substantially horizontal position when the system is submerged.

- the system further includes a first plurality of additional screens SC11, SC12, SC13, SC14 and SC15 arranged from so that they are substantially parallel to the SCI screen of the first device when the system is submerged, and a second plurality of additional screens SC21, SC22, SC23, SC24 and SC25 arranged so that they are substantially parallel to the screen SC2 of the second device when the system is submerged.
- This particular embodiment makes it possible to subdivide the enclosure formed by the capital into multiple chambers, each serving as a settling chamber and sedimentation chamber depending on the direction of the swell. Such a subdivision makes it possible to further amplify the phenomena of settling and sedimentation, and thus to accelerate the accretion process.
- the system advantageously includes at least additional intermediate screens SI2 and SB, arranged between the low and high ends of the screens SC1 and SC2 of the first and second submersible devices and intended to occupy positions substantially horizontal when the system is submerged.
- This variant makes it possible to multiply the number of chambers by subdividing them in a substantially vertical direction.
- the additional intermediate screens SI2 and SB are arranged to interconnect intersections between additional screens belonging to the first and second pluralities SC11, SC12, SC13, SC14 and SC15 and SC21, SC22, SC23, SC24 and SC25.
- each cell can alternatively serve as a settling chamber and sedimentation.
- HF masked floats can advantageously be implemented to increase the flotation of the system.
- the links between screens can be made in various ways, for example by braiding or by shearing.
- a system according to the above description will advantageously include AT link elements having a low tensile strength and intended to provide at least one link between screens.
- This embodiment is especially advantageous in that it makes removable portions of the marquee relative to others. Indeed, when an effort a large amount of traction will be applied to a screen connected to the remainder of the system by means of the aforementioned AT connection elements, these will be broken because the anchoring means of the various devices included in the rest of the system maintain this one. in position.
- FIG. 11 illustrates an embodiment of an AT link element having a low tensile strength and intended to provide at least one link between screens.
- This element AT includes a flexible tongue integral with a main body AT, which is pierced with an orifice to be traversed by a braid of a screen, a braid of another screen being intended to be inserted by pressure against the flexible tongue LG in a space arranged between the flexible tongue LG and the main body PC.
- the AT link element has a specific ENC notch for initiating a break of the AT element, this ENC notch having a depth calibrated so that the break occurs when the link member is subjected to a force. predetermined traction.
- FIG. 12 is a schematic representation of a dismantling process of a DSP device according to the invention.
- Such dismantling is achieved very simply by means of a ship BT which, as it advances in a direction Fwd parallel to the anchor chain ensuring the grounding of the DSP device, winds the said chain on a capstan winch CB actuated in rotation in the ER direction, the screen threads being able to be simultaneously measured on a net hauler winch.
- the invention thus makes it possible to eliminate, if necessary, any trace of any human intervention on the seabed, which is not possible in the current state of the art.
