Definitions

  • the present invention relates to an installation for dredging a seabed, for example for carrying out underwater earthworks or for extracting ores at great depths.
  • the working head which is in contact with the seabed is mounted on one end of a rigid arm, the other end of which is articulated to the hull of a floating body, such as a ship, pivotally about a horizontal axis.
  • the working head is able to carry out dredging passes on the seabed having a trajectory in the form of an arc of a circle, under the control of two butterfly cables which are anchored to the seabed in places located on either side of the working head and pass through means fixed to the working head to come and wind on two winch mounted on the floating body and actuable in the direction of reverse rotation.
  • the positioning and advancement of the installation are generally carried out using two vertical anchoring piles mounted vertically mobile at the ends of the floating body. Advancement installation is done by pivoting the floating body around one of the two piles which is driven into the seabed, while the other pile is raised.
  • the object of the present invention is to propose a dredging installation which no longer has the drawbacks mentioned.
  • the installation for dredging according to the present invention is characterized in that said arm carrying the working head is mounted on a support which is vertically movable on the anchoring device, at least in the lower part of the latter, between a working position in which the arm forms a relatively small angle with the anchoring device and a position in which it is appreciably parallel to the bottom.
  • auxiliary anchoring device vertically movable between a position pressed into the seabed and a position released from this bottom, the auxiliary device being located offset in the direction of widening of the abovementioned annular sector, from the above-mentioned anchoring device a variable distance.
  • the dredging installation comprises a floating body 1, such as a ship in form of a catamaran, an anchoring device for the ship, produced in the form of a vertical stake 2 and a rigid arm 3 which carries at one end a working head 4 and is articulated by its other end to a support in form of a carriage 5 mounted vertically movable along the anchor pile 20
  • the arm 3 is connected to the support carriage 5 by an articulation having a horizontal axis 7.
  • the carriage is provided with a set of pinions 8 driven by a motor 9 and each meshing with a rack 10 extending along the stake 2.
  • the latter may be provided with laterally projecting flanges 11 behind which engage appropriate retaining members 12 associated with the carriage and which comprise for example rollers intended to come into rolling contact with the rear face of the flanges 110
  • the dredging installation comprises an auxiliary vertical pile 13 which is connected by a connecting device in the form of a parallelogram 14 to a carriage 15 mounted vertically movable along the pile 2 in the same manner as the carriage 5 In the figures, only the carriage drive motor 15 and the rack are shown at 9 'and 10'0.
  • This auxiliary pile 13 is further equipped with means allowing a pivoting movement in a vertical plane around the articulation connection. from the parallelogram 14 to the carriage 15.
  • the connection between the parallelogram 14 and the auxiliary pile 13 also allows a pivoting movement relative of these two pieces.
  • the means for controlling the pivoting movement of the pile 13 are formed by a cable 17 fixed at one end to the pile and winding at its other end on a winch 18 mounted on the ship 1.
  • the auxiliary pile 13 is situated substantially in the vertical plane in which the anchor pile 2 and the arm 3 are located with the work head 4, but, with respect to the pile 2, on the side opposite to that of the work head 4.
  • the installation comprises a cable 19 which is wound on a winch 20 on board the ship 1 and is fixed at 21 to the end of the arm 3, on which the working head is mounted 4. Thanks to this cable 19, the arm 3 can pivot vertically around its horizontal pivot axis 7. from its articulation to the support carriage 5.
  • the device ensuring the pivoting of the arm 3 around the vertical axis comprises two cables fluttering 22. anchored at 23 to the seabed 16 on either side of the arm 3. Each cable 22 passes over a pulley 24. fixed to the lower or free end of the arm 3 and is wound on a winch 25 mounted on the ship 1, passing over another return pulley 26 provided in the upper part of the arm 3.
  • the anchor pile 2 is mounted at 34 on the ship 1, vertically sliding between an anchor position in which its lower end is pressed into the seabed (FIG. 1) and a raised underwater bottom release position (Figure 3).
  • the auxiliary pile 13 is also likely to be driven into the seabed or to assume a raised position.
  • the working head 4 can be produced in the form of a suction head whether or not equipped with a cutting tool such as a shovel wheel 27 which can be held in position by a jack 28.
  • a suction pump 29 mounted inside the arm 3 and which delivers the materials sucked through a transfer pipe 30 of these materials to a storage location, not shown.
  • the motors 9 and 9 'intended for the movement of the carriages 5 and 15 and the suction and discharge pump 29 as well as the actuator 28 can be remote-controlled, for example from the vessel 1, in any case appropriate and known.
  • the dredging installation according to the invention operates as follows:
  • Figure 1 shows the installation in a fixed working position.
  • the tip of the anchoring stake 2 is driven into the seabed 16.
  • the carriage 5 to which the arm 3 carrying the working head 4 is articulated is in its high position.
  • the carriage is kept in this position for the entire duration of a dredging pass carried out by the working head 4.
  • the trajectory of this dredging pass is in the form of an arc of a circle represented at 31 in FIG. 2. This sweeping movement of the head 4 along the circular arc 31 is controlled using the two winches 25 and the two butterfly cables 22.
  • the bucket wheel 27 of the working head 4 can be advanced to the line 32 representing the trajec-- b ire of the pass following dredged without it being necessary to move the vessel 1. For this, it suffices to move the carriage 5 downwards, to which the arm 3 carrying the working head 4 is articulated, at an appropriate distance. In fact, any vertical movement of the carriage 5 causes movement of the shovel wheel 27 on the seabed, forwards or backwards in the direction of movement of the carriage 5, since the anchoring stake 2 is kept fixed and the shovel wheel 27 is in contact with the seabed 16.
  • the upward movement of the carriage 5 causes the desired advancement of the ship 1. Simultaneously the butterfly cables 22 are kept taut to prevent the working head 4 does not slip on the bottom and moves backwards. Since the auxiliary pile 13 remains in its depressed position in the bottom 16 during the whole operation of advancing the ship 1, the latter is always anchored to the seabed and the advancement operation is perfectly controllable.
  • the dredging installation according to the invention makes it possible to work on the bottom marine at depths up to 100 meters and even more and sweeping by successive parallel passes without changing the working position of the installation, and this in particular thanks to the articulation of the support arm of the working head at a motor carriage movable along the anchor pile 2 to the seabed 16.
  • the embodiment which has just been described and which is shown in the figures has been given by way of example only. Of course, many variants can be made to this embodiment.
  • the configuration and mounting of the two carriages on the main anchor pile 2 can be different and of any suitable nature known to those skilled in the art.
  • the working head is also not limited to the structure described and shown.
  • the ship can be equipped with an autonomous or additional propellant device to facilitate the advancement maneuver.
  • the anchoring stake can be produced in any suitable form and have a cross section of any suitable form.
  • the extreme part of the pile which is intended to be inserted into the seabed, is advantageously made in the form of a separate body mounted to rotate and, if necessary, vertically movable in the pile.
  • the pile can be made up of a multitude of assemblable sections so that it is adaptable to the depth of the seabed.
  • the invention includes all the means constituting technical equivalents of the means described, as well as their combinations, if these are executed according to the spirit and implemented in the context of protection as claimed.
