Definitions

  • the present invention relates to door-boats whose function is to ensure the watertight closing of entrances to dry docks overlooking the sea, to allow the dry docking of ships (see eg FR-A-2 129 082).
  • a door boat consists of an outer envelope and an internal framework stiffening the assembly and dividing it into compartments, most of which are ballasts.
  • the envelope Along its bottom and its sides, the envelope has a bearing surface with seal, intended to be applied against the masonry of the basin entrance to be closed.
  • a ballast is generally provided in the bottoms, and a pumping and emptying system makes it possible to selectively fill or empty the different ballasts.
  • the shape, mass, stability, arrangement of the ballasts and their volumes are determined in such a way that the carrier boat is as likely to float freely with variable drafts, as to rest on the bottom and to seal the entrance to a basin, with negative buoyancy (preponderance of safe casting).
  • the door-boat is held in place by the only pressure of the water, sea side.
  • Door-boats have always been made of riveted steel sheets, or welded for the most recent. Their shapes and dimensions are deduced from the different buoyancy conditions. Thus, as a rule, they have a bulging lower part with respect to a narrower upper part. to lighten the assembly and obtain acceptable stability characteristics.
  • the invention was carried out with the aim of overcoming this drawback by providing for the use, for the construction of door-boats, of composite materials, for example of the fiberglass-resin type, which have the advantage of being insensitive to marine corrosion.
  • Another sought-after goal was to design a new door-boat architecture adapted to the use of composite material which, while satisfying all the technical requirements, in particular of mechanical resistance, either of simple shape and construction and of reduced width, and therefore lower cost.
  • This architecture in two parts makes it possible to produce the envelope and the frame independently of one another so as to assemble them only afterwards. It also allows an extremely simplified envelope form which greatly facilitates construction in composite material, only the frame being subjected to form constraints to constitute the support against the masonry of the entrance to the basin to which the boat- door is intended.
  • the frame is provided in concrete, at least as far as its lower part is ballasted.
  • the envelope and the concrete parts of the frame are fixed by bolting on threaded rods anchored in the concrete.
  • the frame has a profile substantially the same width as the envelope at the junction with it. It therefore completely covers the envelope along the bottom and on the two lateral sides, providing its mechanical properties, and in particular its rigidity, to the assembly.
  • the door boat shown in the drawings has a general trapezoidal shape which corresponds to that of the masonry rebate at the entrance to the basin for which it is intended. This is a usual form due to the fact that the side walls of the refit basins are most often stepped, and the rebate then follows their line of slope.
  • this trapezoidal shape of the door-boat is produced at the outer periphery of a frame 2 which borders the body of the boat itself along its bottom and on its two lateral sides.
  • the frame has two vertical planar faces 21 on each side of a horizontal base face 20 also planar, so as to receive as the body of the boat an envelope 1 in the form of a rectangular parallelepiped.
  • the envelope 1 can be prismatic, with longitudinal walls 13 in the form of an isosceles trapezoid, to avoid widening the sides of the frame upwards.
  • the casing 1 is made entirely of composite material, advantageously of the fiberglass-resin (CVR) type. Its bottom 10, top 11, side 12 and longitudinal 13 walls define a volume interior divided into compartments 17 by a set of horizontal platforms 14 and vertical partitions 15. The compartments are for the most part ballasts, the others housing the members such as pumps 18, FIG. 1, used for the operation of the door boat.
  • CVR fiberglass-resin
  • the platforms 14 and partitions 15 on the other hand constitute a framework having the function of contributing to the rigidity of the envelope 1.
  • Transversal stiffeners 16 are attached to the platforms 14 and internally on the base walls 10 and top 11 of envelope 1.
  • the use of composite material to produce the casing 1 results in a significant overall weight gain compared to a steel construction.
  • the walls consisting of a superposition of folds it is easy to modulate the number of folds and therefore the thickness and the surface mass, between the different walls, and even between several zones of the same wall, depending their position in the envelope which requires more resistance in its lower part than in its upper part.
  • the walls 10 to 13 of the envelope, the platforms 14 and the partitions 15 may they be less and less thick from the bottom up.
  • the envelope 1 will therefore be lightened in its upper part where it is least stressed, but also where the mass is detrimental for stability.
  • Fig. 3 shows in fine lines boxes 30 of simple shape which can be attached to either side of the casing 1 in certain cases, in particular when the draft constraints are severe.
  • the frame 2 which must perform a ballast function at the level of the lower part of the casing 1 and which, on the other hand, must constitute a rigid and non-deformable peripheral support to ensure the tight closure against the rebate of the entry of basin, is in a satisfactory embodiment provided in concrete, reinforced for example by means of fiberglass rods, which brings its advantages of ease of implementation and of insensitivity to marine corrosion like composite materials.
  • the frame 2 has a cross section symmetrical with respect to a median axis normal to the side corresponding to the internal face 20 or 21. From this internal face 20 or 21, the body of the profile has a constant width, substantially equal to that of the envelope 1 over a certain distance d, FIG. 3. Then, the width decreases until the birth of a peripheral wing 22 which constitutes the support for closing and sealing the frame.
  • the bearing face of the wing 22 is provided with an elastomer seal 23.
  • the distance d is constant along the horizontal base part 2a of the frame 2, where it is in particular a function of the desired mass of ballast. On the other hand, it increases linearly from bottom to top along the length of the uprights 2b of the frame, due to the flared, trapezoidal shape of the peripheral support 22.
  • a profile evolutionary amounts 2b tending for example to the form shown schematically by the dashed lines 24 in FIG. 2.
  • a low density load component may be incorporated into the concrete of the upper part of the uprights. It would be also possible to use different materials for the realization of the base 2a on the one hand, and the uprights 2b on the other hand.
  • the frame 2 is constructed in several stages, or in several separate elements, for example the base part 2a and the uprights 2b which will then be assembled with the casing 1.
  • the rods 3 are passed through holes in the walls 10 and 12 of the envelope, then receive tightening bolts.
  • the reference 4 designates clamping plates, which on the frame side are embedded in the concrete to be flush with the surfaces 20, 21 in contact with the walls of the envelope.
  • the envelope 1 with a length of approximately 15 meters has a width only 1.6 meters for a height of 7.5 meters, the width / height ratio therefore being of the order of 0.2.
