    专利说明:

    The present invention relates to a method and a device for maintaining a floating platform, in particular a platform supporting a structure for residential or office use and more generally buildings receiving the public.
    There are structures intended to be floating and positioned on bodies of water, watercourses which do not allow navigation of said structures up to these bodies of water or watercourses due to their draft. or their dimensions.
    Bridges can also prohibit the passage of structures of a certain height, the meanders can be too tight on certain rivers.
    In addition, structures made from boat hulls such as disused barges do not allow architectures to be varied and do not provide sufficient floor areas. In all cases, the hull must undergo a periodic inspection and it is not a solution to use a monolithic hull of large dimensions.
    There are possibilities of making structures directly from a floating platform.
    In this case, the platform is made from floating boxes connected together, supporting a base from which is erected the structure intended to constitute the habitable, usable volume.
    The advantage is to allow total freedom on the architecture of the erected part.
    Buoyancy is studied to allow the weight of said erected part to be taken up in buoyancy.
    Thus, certain aquatic areas can receive structures of sufficient size to allow the structure to be used as a restaurant, offices, or dwellings of several hundred m 2 .
    The place can be located near the city centers or on the contrary in fluvial or maritime zones subject to the risks of strong variations of height of water, on water.
    The erected structure has the advantage of being floating with all the amenities that it provides, both in sensations and in external view. In addition, this allows to invest unused or unusable areas with traditional constructions.
    Some countries like the Netherlands colonize these vast unused areas to transform them into veritable marinas, even a floating urban district.
    Like any floating structure, the submerged part must be inspected regularly.
    The erected structure remains always accessible like earth constructions and subject to all town planning and especially safety rules, standards, calculations, regulations. This part therefore poses no problem.
    Such a structure, like the base, moreover, can be made in metal construction, in wood construction, with parts made of composite materials or not.
    The platform is held in place by moorings, a quay, piles and / or anchors at the bottom of the water.
    The floating boxes can be of any kind, concrete, metal, composite materials or a combination of these materials.
    The goal is to have enough volume to generate an Archimedes thrust greater than the weight of the platform, the structure and the caissons themselves.
    Each hollow box therefore has at least part of the surfaces which constitute it, permanently submerged.
    However, this submerged part of each box requires, according to legislation, inspections in order to verify the integrity of this submerged part, subject to corrosion, shocks from ice jams, wear by friction, degradation by colonization by microorganisms. .
    This technical check can be carried out by putting the caissons / platform / structure together in the case of boat hulls, in the case of small platforms. The problem is that, as soon as the dimensions are large, such a dry-out becomes impossible or at least would require means that are not technically or financially acceptable. Such dryness may even prove impossible due to lack of accessibility, due to the quality of the soils of the banks supporting a lifting machine, due to the small space available to develop such crane means, including cranes. on floating barges, due to the absence of land to accept the dryness of such an assembly, to name only these obstacles.
    Such a control can, depending on the legislation, take place for example every 5 years, which is a relatively short period.
    One solution is to have the submerged part inspected by a diver qualified in underwater work. Such divers are few and expensive, not to mention their low availability. Such a service generates risks and above all does not allow satisfactory control in certain cases, due to the turbidity of the water for example and / or between the caissons, unless provision is made for their arrangement to allow sufficient passage between the caissons, which decreases the floating surface and therefore increases the necessary depth of said boxes.
    In some very limited applications, a dry dock is available nearby, but these cases are too rare to be considered as a solution, this being also complex to implement and very expensive.
    The present invention provides a method and variants of devices for implementing said method, which make it possible to control each box, in the dry, in the best conditions, visually but also by relying on all non-destructive control means without that they are necessarily waterproof due to the shore inspection.
    We also note that the volume of a box as well as the weight represent values without common measure with those of the structure. The handling is excellent.
    The method proposes to have n boxes under the platform, in sufficient number so that at least one box can be removed while retaining the buoyancy of all of the n boxes at least one box, the platform and the structure.
    According to the method, the at least one box is detached and removed from the platform, said box is kept dry, said box is checked, possibly repaired or even changed, and the box checked, repaired or changed is put back in water and repositioned under the platform.
    The method provides for removal of the boxes by periodic circular permutation.
    The invention also covers devices for removing and replacing a box under a platform.
    According to the arrangement according to the invention, each box comprises ballasting means such as means for introducing water into said box and draining means as well as means for connecting said box to the platform.
    These connecting means comprise according to a first variant a keying / unclogging with locking / unlocking so as to allow removal of said box by vertical translation.
    These connecting means comprise, according to a second variant, sliding means in a plane parallel to that of the platform, interposed between said box and the platform so as to allow removal of said box by horizontal translation.
    The method and the device according to the present invention are now described by way of illustration with reference to the appended drawings, drawings in which the figures represent a non-limiting embodiment and more particularly the figures show:
    FIG. 1. a perspective view of a floating assembly comprising a structure attached to a platform itself disposed on floating boxes, according to the invention,
    - Figure 2: a side elevational view of the assembly of Figure 1,
    - Figure 3: a top view of the assembly of Figure 1,
    Figure 4: a perspective view of a box with partial cutaway,
    FIGS. 5A to 5D: a block diagram of the method according to the present invention implemented from all of FIGS. 1, 2 and 3.
    In Figures 1 to 3, there is shown a platform 10 floating on the water, supporting a structure 12.1 together being positioned on a body of water such as a maritime zone, a fluvial zone or even a plane of water, referenced, whatever it may be, by the letter E.
    The platform 10 comprises a base 14 on which the structure 12 is placed. This base 14 rests on n floating boxes 16-1 to 16-n with a water line L determined during the study and making it possible to locate the maximum submergible part .
    The number n of floating caissons is adapted so that the removal of at least one floating caisson 16 makes it possible to maintain the buoyancy of the platform and that the penetration is always limited so that the water line L of the platform 10 or above the surface of the water. The platform 10 can therefore be supported by n-1 boxes.
    It is also possible to provide a number of boxes equal to twice the number n of boxes required, or 2n, so that half of the boxes can be removed while keeping the waterline above the surface of the water.
    The boxes are also arranged in a suitable way to allow balancing of the platform while ensuring the recovery of mass imbalances.
    Each box 16 is described with reference to FIG. 4. Each box, in the embodiment shown, is parallelepipedic with 6 faces, constituting a closed and sealed interior volume.
    On the upper face, for example, there are provided means 18 for accessing the interior volume 5 of said box, for example a sealed inspection hatch 20 and ballasting / deballasting means 22, for example an assembly 24, comprising a valve and a dip tube which extends to the bottom of said box, connected to pumping means, this being within the reach of ordinary skill in the art and not part of the present invention.
    Between the upper face of each floating box 16 and the base 14, it is interposed means 10 connecting 26 to the base 14, the first part 28 of these connecting means being carried by the box, comprising for example ears, in the occurrence 4 ears, 28-1 to 28-4.
    The base 14 is, for example, made of metal construction to form a frame suitable both in geometry and on the surface for receiving the structure 12 in the upper part. On the lower face, the base 14 comprises the second part 30 of the connecting means 26 15 intended to secure, in a removable manner, each box. These connecting means 26 are represented schematically by keyways 30-1 to 30-4, intended to cooperate with the ears 28-1 to 28-4.
    According to a variant, the ear / keying assemblies could be replaced by slides secured to the boxes and slides secured to the base.
    The boxes 16 are thus mounted in a drawer relative to the base 14.
    The structure 12 is attached to the base by any suitable means, this structure not forming part of the present invention and relating to construction and the building.
    The platform carrying its structure is immobilized by any means at the chosen location, by mooring to a quay, to piles or even to submerged anchors at the bottom of the water.
    The integrity check of the boxes having to be carried out periodically, for example every year, the method according to the present invention consists in carrying out the steps which are now detailed.
    On the ri floating boxes 16, at least one floating box is inspected, each floating box 16 is inspected in turn in the simplest version of the process.
    The floating box 16 identified or filled with ballast water, advantageously pumped into the natural environment, by the access means 18, for example through the assembly 22, valve and dip tube. The identified floating box is filled until a slightly negative buoyancy is obtained. The floating box 16 identified neither then presents a flowing movement. The floating or unidentified box is ballasted so that it flows and sinks to a desired level of equilibrium which must be at least lower than the level of the n-1 other boxes.
    According to the next step of the method, the connection means 26 are activated to separate the floating box from the base 14. For example, the ears 28 are released from the keyways 30.
    The ballasted floating box is floating, with a deeper penetration than that of the other boxes and can therefore be released from the base 14 and towed, in order to be able to transfer the box released in the water to the shore control site, by grounding , craning or by any other means.
    The box is emptied of the ballast water introduced before its stranding, after its stranding, preferably before its craning.
    According to the next step, the box is checked on the ground in an appropriate manner according to the nature of the materials and according to the regulatory controls to be carried out. The floating box 16 can also be repaired if necessary.
    In the embodiment, the inspection hatch 20 can allow visual inspection of the interior walls. The controls can use all non-destructive testing techniques depending on the nature of the materials.
    According to another successive step, after the control, the caisson is then returned to the water and again filled with water so as to obtain a slightly negative buoyancy until an equilibrium and a depression greater than that of the other caissons. , identical or close to the depression initially made during ballasting.
    Once filled, the floating box 16 identified neither is led again to the right of its position, under the base 14.
    The last step consists in draining the ballast water, which causes a vertical upward displacement of the floating box 16 identified neither and the connecting means are then actuated to re-join the floating box 16 identified or just having been checked, to the base. The actuation of the connecting means consists, in the embodiment shown, of keying the ears.
    In the case of a sliding arrangement, the movements of withdrawal and of replacing the boxes are obtained by translation in a substantially horizontal plane.
    According to a variant of the present invention, there is provided a number 2n of floating caissons, double that which is necessary for buoyancy.
    It is thus possible to carry out a control of the whole of the first half n of the boxes, while leaving the second half n of the boxes in place, to support the platform and the structure.
    In addition to the greatly increased safety factor, the platform is always equipped and supported by approved floating boxes, able to support the entire platform and the structure it carries.
    Likewise, the control materials having to be brought to the site, the time saved by bringing and making available the batch of n boxes to be controlled simultaneously on the said control site, is significant and the cost of the control is greatly reduced. by working in batches.
    The method according to the present invention thus allows dry control and in optimal conditions of each box, without in any way interrupting the use of the structure, in total safety conditions for its possible occupants.
    As the structures are LES, an establishment open to the public, it is understood that the standards are rigorous so that the frequency of controls will tend to increase rather than decrease in the future.
    The process is therefore safe, economical, improves the technical quality of the control, the reliability of said control.
    As for the maintenance device, namely the arrangement of the boxes to be able to ballast / unballast, it aims to overcome a prejudice according to which a floating box must not have means allowing it to confer a slightly negative buoyancy.
    It is understood that the control of the ballasting of the caissons can be automated using a pump with a measurement of the volume of ballasting water just as for deballasting.
