Definitions

  • the present invention relates to a system for leveling and consolidating the sea floor on which a foundation or any other type of device that requires a level and consolidated floor is to be installed.
  • One of the most important problems when installing a foundation of a platform or any other device on the sea floor is to achieve a level and pressure and erosion resistant floor that provides a good foundation for the foundation.
  • the applicant firm does not know so far the existence of a system that allows leveling a circular or polygonal area of the sea floor, of any size, and, in turn, allows it to consolidate.
  • the present invention provides a system that solves the previous deficiencies in the state of the art and allows the leveling and consolidation of the sea floor as a stage prior to laying a foundation or any other structure.
  • the system object of the present invention consists of a suction bell of cylindrical shape that will be driven into the area of the bottom of the sea that you want to level and consolidate. Likewise, it consists of a series of cylindrical and telescopically connected tubes located inside the suction bell and protruding from it. The upper part of the bell is threaded and a piece with internal thread is screwed onto it, to which a plurality of "L" shaped tubes are welded around it. The tubes are welded to the piece at different heights of the piece and so that one section of the tubes remains in an upright position and the other section in a horizontal position.
  • a pinion connected to the "L" shaped tubes and which allows them to rotate while rotating the threaded piece in the upper part of the bell.
  • the telescopic tubes are equipped with an anti-rotation system, so they remain immobile.
  • the bell is set at the bottom of the sea that we want to level.
  • the inclined and continuous sheet begins to scratch the floor and begins to distribute the scratched material from the floor of the highest zone to the lowest zone, leveling it.
  • the trailed excess material is thrown out thanks to the design of the inclined and continuous sheet, which has a curvature at the end furthest from the suction bell.
  • the ground to be leveled can be the size we want, since other pipes can be joined to the horizontal sections of the "L" tubes so that the scanning radius is increased.
  • the leveling system can comprise a series of additional elements that allow the soil to be consolidated while it is leveled.
  • These elements are a hopper that is filled with concrete or gravel grout, etc. connected to the "L" tubes and progressive cavity pumps that are located within the vertical part of the "L” tubes.
  • the axis of said pumps is connected to pinions which, in turn, are connected to the pinion which is located in the upper part of the innermost concentric tube and which causes the "L" tubes to rotate.
  • Figure 1 Elevation view of the leveling and consolidation system of the sea floor.
  • Figure 2 Plan view of the leveling and consolidation system of the sea floor.
  • the leveling and consolidation system of the sea floor object of this preferred embodiment, consists of a suction bell (1) that is driven into the sea floor.
  • the upper and outer part of the bell is threaded to a length of one meter.
  • a piece (2), with an internal thread, is screwed onto the bell (1), to which four "L" shaped tubes (3) are welded around them and as far apart as possible from each other and at different heights of the piece.
  • a motorized pinion (7) connected to the tubes (3) which allows them to rotate while rotating the part (2).
  • the system also contains a hopper (8) filled with concrete grout and connected to the tubes (3) and four progressive cavity pumps that are located within the vertical part of the tubes (3). Said pumps are moved by means of pinions that are connected to the motorized pinion (7).
  • the motorized pinion (7) moves, the tubes (3) begin to rotate, as well as the progressive cavity pump, so that the grout begins to fall through the tubes (3) until it leaves the tubes (4) and it is deposited on the sea floor while it is leveled.

Abstract

La présente invention concerne un système de nivellement et de consolidation du sol marin comprenant une hotte aspirante (1) plantée dans le sol, une pièce (2) vissée à la hotte (1), des tubes (3) en forme de "L" soudés à ladite pièce (2), des tubes (4) raccordés perpendiculairement à chacun des segments horizontaux des tubes (3), des plaques inclinées et continues (5) aux extrémités libres des tubes (4), des tubes raccordés de manière télescopique (6) à l'intérieur de la hotte aspirante, ainsi qu'un pignon (7) qui permet la rotation des tubes (3). Pour la consolidation du sol marin, le système comprend également une trémie (8) dans laquelle est stocké le coulis qui va être utilisé pour consolider le sol, des pompes à cavité progressive qui se trouvent dans la partie verticale des tubes (3), ainsi que des pignons reliés à l'axe des pompes.
