Definitions

  • JP-A-9183399 describes a modular floating structure whose assembly of the floating blocks is carried out by means of the upper part of the metal anchoring pillars, while the pointed lower part of these anchoring pillars is firmly planted in the submarine soil to immobilize the structure in its destination location.
  • a structure is constituted by parallelepiped or cubic modular floating blocks whose vertical edges are provided at their upper end with a conical recess extending over 90 ° and, below this obviously, ears arranged at different levels. ; such that when four blocks are contiguous to each other, a conical housing is formed below which said lugs are aligned, said blocks being joined to each other by a connecting key having a conical upper part, which comes engage in the conical housing and a cylindrical lower part, which engages in the superimposed orifices of the ears.
  • the anchoring or fixing of the structures thus constituted is achieved by horizontal bars provided with lugs cooperating with the ears of said blocks so as to be traversed by keys, these bars being arranged on the side of said structures.
  • JP-H01-123995-U discloses a floating structure consisting of floating blocks, modular, parallelepiped whose vertical edges are provided with ears in which are inserted connecting elements. Some connecting elements between the floating blocks are used for fixing a rope disposed at the periphery of the floating structure and on which is attached a second rope for anchoring the floating structure.
  • a first object of the present invention is to provide an improvement in the stability of such structures in case of rough sea and, more particularly, to improve the stability of the structures described in the French patent. 2,699,495 VEYRIERES quoted above.
  • a floating structure of the type constituted by floating blocks, modular, parallelepipedic, whose vertical edges are provided with ears in which are inserted connection elements ensuring their assembly is characterized by the fact that said structure comprises one or more anchor points, which are located below and within said structure.
  • a second object that is not covered by the present invention is to enhance the functionality and applicability of a modular floating structure.
  • a floating structure of the type consisting of floating blocks, modular, parallelepipedic, the vertical edges of which are provided with ears in which connection elements are inserted to assemble said blocks is characterized by the fact that the connecting elements comprise a support key, which carries at its upper part a candlestick extending above an upper surface of the floating structure, said candlestick being provided with an eyelet adapted to constitute a fixing point for a net.
  • a basic idea is the modification of the connecting keys so that they can, in addition to their binding function, have a supporting function for various devices such as guardrails, aquaculture nets or nets for maintain oil slicks.
  • a floating structure can be used as an anti-pollution dam on a body of water. According to embodiments, the features can also be combined.
  • These blocks consisting of parallelepipedic structures with a square base are generally hollow synthetic material and are assembled to form a surface for the movement of people or equipment.
  • These structures have multiple applications such as floating pontoons, aquaculture ponds, recreational areas or the possibility of carrying out work on bodies of water. Because of their modular structure it is possible to create multiple geometric shapes according to the nature of their use.
  • the floating structure is constituted by blocks 1, which are modular, floating, parallelepipedic, the vertical edges of which are provided with lugs 3 in which are inserted connecting keys 2, which assures their assembly to each other .
  • Fixing such assemblies at a fixed point, for example mooring bollard, dock or anchor, is provided by bars such as the bar 4 which is provided with ears 5 which cooperate with the ears 3 of the blocks 1 located on the The structure of the structure is thus fixed on its sides to a fixed point such as a dock, a ship or anchor.
  • This side attachment mode has the disadvantage that when the sea is very agitated the edges of the structure plunge, the water passing over it, which affects its resistance.
  • one or more modified link keys are used to provide anchor points, as shown in FIG. figure 2 .
  • an anchor key 20 which has the same shape as the connecting key 2, its rod 21 having the same lugs 22 or grooves as those described in the patent 2,699,495 , which cooperate with the ears 3 to assemble the blocks 1; but the rod 21 of this anchoring key 20 is hollowed out with a bore 23 open at its lower end 32 opposite the surface 33, which is flush with the upper surface of the blocks 1.
  • a rope 24 preferably of synthetic material
  • the end loop 25 is traversed by a stop rod 26, preferably stainless steel, through two orifices 13 dug transversely to the rod 21 near the bottom 14 of the bore 23.
  • the rope 24 is attached by a shackle 27 to a mooring line 28, which may be a chain, which is fixed to a dead body 29 or to an anchor ( figure 3 ).
  • stop rod 26 disposed across the bore 23 and the rope 24 provide an anchor point of the structure 10, formed by the assembly of the blocks 1, which is arranged inside and below of said structure 10.
  • This arrangement provides many benefits. It makes it possible to place the anchoring point inside and below the floating structure without modifying the resistance of the system, because the anchoring key 20 plays the same role of fixing as the connecting keys 2.
  • the Anchoring works on four ears 3 and not just two as in the previous arrangement, which is an important advantage in heavy weather.
  • the fixing bars 4 of the figure 1 placed on the periphery of the floating structure, have the effect, when they are stowed at a fixed point either in heavy weather, or because of the current, to plunge the edge of the structure into the water, which offers resistance to the flow of waves and water.
  • the traction exerted under the floating structure 10 makes the edges of the blocks 1 located opposite the anchor point rise, which facilitates the passage of the waves and the flow of the water, all by preventing water from passing over the floating structure.
  • the metal parts such as the shackles 27 are permanently immersed, while the bar 4 and the ears 5 are sometimes in the air, sometimes water which accelerates their oxidation.
  • the stop rod 26 works in vertical support on a washer 30, which is itself resting on one of the lugs 3 of the block 1: it follows that these lugs 3 are no longer stressed in tension as in the device known to the figure 1 .
  • the superposition of four lugs 3 belonging to four blocks 1, whose anchoring key 20 assembles at their adjacent corners, has been sketched in broken lines.
  • one or more anchoring points can be arranged by means of one or more anchoring keys 20.
  • the rest of the structure 10 can be assembled by means of the connecting keys 2 and / or support keys 50 which will be described below.
  • This new method of anchoring with the advantage of preventing the floating structure from sinking into the waves in heavy weather, makes it possible to use it effectively for uses such as aquaculture or to form dams. floating and in particular floating dams to contain an oil spill.
  • the figure 4 represents a candlestick 40, carried by a support key 50, fulfilling the same function of connecting the parallelepipedic blocks 1 as the connecting key 2 of the figure 1 and the anchor key 20 of the figure 2 , and having a similar form.
  • the support key 50 can be made in one piece with the candlestick 40, for example high-density polyethylene resistant to exposure to ultraviolet radiation and hydrocarbons. A bright color can be used to improve visibility and safety, for example a bright yellow.
  • the support key 50 has a conical upper portion 99, which engages in the conical housing formed by the assembly of four blocks, such as the conical portion 51 of the anchoring key 20.
  • the support key 50 also comprises a cylindrical lower portion 52 and 53, the portion 52 having rotational locking means and the portion 53 being threaded to receive a nut 98, visible on the figure 7 .
  • the candlestick 40 has at regular intervals eyelets 41 to 44, which are attachment points for various devices, such as for example a net.
  • the figure 5 represents a floating structure 100 made of an assembly of floating blocks such as the blocks 1 of the figures 1 and 3 .
  • these blocks 1 are aligned three by three so as to achieve a structure in length.
  • a net 45 To these candlesticks is fixed a net 45. Because there are eyelets 41, 42, 43 and 44, this net can be fixed at different heights. A lead rope 46 keeps the net 45 immersed in a substantially vertical position.
  • the candlesticks can be arranged at will: at all blocks, or every two blocks or every three blocks or at any desired interval.
  • eyelets 41, 42 etc. at several levels it is possible to adapt the height of the net 45 according to sea conditions and the pollutant to prevent the passage of it over the floating structure 100.
  • candlesticks 40 also make it possible to easily raise the net 45 to put it in an inoperative position, for example folded on the surface 94, in order to preserve the ecosystem, where possible, for example during the movement and the installation. of the pollution control dam.
  • the candlesticks 40 may be, optionally, arranged along the edge 97 of the floating structure 10 or disposed within this structure between two rows of blocks 1, or at any other desired position, in particular at a outer corner of the floating structure 100. The latter possibility is illustrated on the Figures 7 to 10 .
  • the blocks 1 not having sharp angles it prevents the tear of the net 45.
  • the implementation is easy because the staff can easily walk and move on the floating structure; to improve security a handrail 90 can be attached to the highest eyelets 44.
  • the net 45 is fixed by garcette or carabiners which is very easy; the mesh size of the net can be adapted to the type of pollutant; the height of the net can be adapted to the conditions of the sea; the weight of the headline 46 can be adapted to the conditions of the site; we can adapt the depth to which the net plunges; the length and the shape of the floating structure 100 can be adapted as desired.
  • a buoy 93 can be added to the anchoring lines 28, which dampens the voltage variations of the lines 28 when the sea is agitated.
  • FIGS. 7 to 10 are four perspective views of the four ears I, II, III and IV, arranged at different levels.
  • the figure 7 represents ear I. As can be seen this ear I is disposed on a vertical edge of block 1, this edge being rounded, and it is placed at about half the height of this edge.
  • the rod 52, 53 of the support key 50 passes through the orifice of the lug I and is held in position by shims 54: a shim 54 above the lug I and two shims 54 below.
  • the figure 8 represents the ear II. It is disposed on another edge of the block 1, at a level a little lower than that of the ear I.
  • the rod 52/53 which passes through this ear II is held in position by wedges 54: two wedges 54 to- above and one below.
  • the figure 9 represents the ear III. It is arranged on a third edge of the block 1, at a level a little lower than that of the ear II. To hold the rod 52/53 there are four spacers 54 three above and one below.
  • the figure 10 represents the IV ear. It is arranged on the fourth edge of the block 1, at a level a little lower than that of the ear III. To hold the rod 52/53 there are five shims 54, four above and one below.
  • the figure 11 represents the assembly of two blocks 1 by means of a support key 50 passing through ears I and II.
  • the figure 12 represents the assembly of two blocks by means of a support key 50 passing through ears I and IV.
  • the figure 13 represents the assembly of two blocks 1 by means of a support key 50 passing through ears II and III.
  • the figure 14 represents the assembly of two blocks by means of a support key 50 passing through the ears III and IV.
  • connecting keys 2, anchoring keys 20 and support keys 50 can be used together, in any combination possible, to achieve a floating structure combining the stability advantage provided by the anchor keys 20 and the functionality of the support keys 50, in particular to achieve an anti-pollution barrier.
  • These keys 2, 20 and 50 can also be used independently of each other.
