Definitions
- the present invention relates to a suction pile intended to be driven into a seabed, in particular in a shallow seabed.
- Suction piers are used to anchor facilities or structures in the seabed to keep them in a fixed position.
- These well known suction cells comprise a cylindrical wall and inside, a partition which divides the cylindrical wall into two sealed chambers vis-à-vis the other.
- the cylindrical wall then has an open suction end adapted to be applied against the seabed so as to close one of said chambers.
- This chamber is then filled with water and pumping means are adapted to extract the water from said chamber to create a depression and cause the depression of the cylindrical wall in the seabed.
- pumping means are adapted to extract the water from said chamber to create a depression and cause the depression of the cylindrical wall in the seabed.
- a problem that arises and that aims to solve the present invention is to facilitate the penetration of suction piles in shallow seabed.
- the present invention proposes a suction pile intended to be driven into a seabed, said seabed being surmounted by water, the water having a bottom hydrostatic pressure in the vicinity of said bottom, said stack suction nozzle comprising a cylindrical wall and a piston movable inside said cylindrical wall, said cylindrical wall having an open suction end adapted to be inserted into said seabed, said piston sealingly delimiting two opposite chambers, one of said chambers extending between said suction end and said piston being capable of filling with water when said suction end is disposed against the seabed, said suction cell further comprising pumping means for extracting the water contained in said one of said chambers and causing the depression of said suction end open in said seabed;
- said suction cell comprises means for blocking said piston with respect to said cylindrical wall, whereas said cylindrical wall has a water inlet end opposite said suction end with respect to said piston to allow arrival of water at the hydrostatic pressure in the other chamber; and said piston is alternately locked and driven in motion from said suction
- a feature of the invention lies in the hydrostatic pressure of the other chamber, opposite to the suction chamber and also in the mode of cooperation of the piston and the wall cylindrical, which are alternately blocked with respect to each other as the cylindrical wall sinks into the seabed.
- the piston is initially driven towards the open suction end and is blocked at a distance from the latter, so as to provide a suction chamber filled with water.
- the cylindrical wall extends vertically on the seabed, and the piston located near the bottom is then subjected to the hydrostatic pressure of the seabed, since the water inlet end has allowed the filling of the wall cylindrical.
- the piston which is blocked relative to the cylindrical wall transmits the forces it undergoes thanks to the hydrostatic pressure, and which are exerted vertically towards the seabed. Therefore, the combined effects of suction of water from the suction chamber and the aforementioned forces on the cylindrical wall allow a faster depression of the suction pile.
- the cylindrical wall sinks into the seabed and the suction of the water from the suction chamber, the sediments of said seabed rise up into the suction chamber and then come against the piston.
- the initially blocked piston is then unlocked and then drag towards the water inlet end for a certain distance, allowing water to enter the suction chamber, then being blocked again in the vicinity. of the seabed.
- the piston is then always subjected to the hydrostatic pressure of the seabed, and the forces it undergoes being transmitted to the cylindrical wall.
- the piston can then be sequentially reassembled until the total depression of the cylindrical wall.
- said water inlet end has an opening corresponding substantially to the cross section of said cylindrical wall so that the other chamber which surmounts the suction chamber is initially filled with water and therefore the piston subjected to the hydrostatic pressure.
- said locking means preferably comprise a line, for example formed of a chain, connected to said piston and retaining means of said line for retaining said line in a direction from said water inlet end towards said suction end.
- said water inlet end has a passage path of said line to allow the extension of said line outside said cylindrical wall.
- said driving of the piston towards the water inlet end likely to be carried out by translating said line in a direction opposite to the seabed, for example by means of a winch installed on a surface boat.
- said retaining means of said line are mounted on said cylindrical wall at said water inlet end, so that the piston can be driven from the suction end to the end. water inlet over the entire length of the cylindrical wall. In this way, the entire cylindrical wall can be driven into the seabed with the help of the piston on which the seabed hydrostatic pressure is applied.
- said retaining means of said line comprise controllable locking means which alternately allow to unlock and re-lock said line as the piston is raised towards the water inlet end.
- said pumping means are adapted to extract the water in said one of said chambers through said piston to reject it in said other chamber and create a depression in said one of said chambers.
- they are for example installed on the piston.
- the pumping means are deactivated and they allow water to enter the suction chamber.
- said piston is advantageously equipped with a circular seal to seal between said two opposite chambers.
- Figure 1 is a schematic perspective view of a suction pile according to the invention
- FIG. 2 is a diagrammatic view in vertical section of the suction cell illustrated in FIG. 1 in a first phase of implementation
- FIG. 3 is a diagrammatic view in vertical section of the suction cell illustrated in FIG. 1 at the end of the first implementation phase illustrated in FIG. 2;
- FIG. 4 is a diagrammatic view in vertical section of the suction pile illustrated in FIG. 1 in a second phase of implementation.
- FIG. 5 is a schematic vertical sectional view of the suction cell shown in Figure 1 ending said second phase of implementation.
- FIG. 1 illustrates a suction stack 10 according to the invention and intended to be driven into a seabed.
- the suction cell 10 has a cylindrical wall 12 which extends longitudinally along an axis of symmetry A and in which is mounted a piston 14 movable in translation along said axis of symmetry A.
- the cylindrical wall 12 has for example a length between 18 and 25 meters and a diameter between 7 and 12 meters.
- the piston 14 delimits sealingly, thanks to a seal 16 which surrounds it and which is pressed against an inner surface 18 of the cylindrical wall 12, two chambers each of them is sealed to each other, a lower suction chamber 20 and an opposite upper chamber 22.
- the seal 16 is for example an expandable seal, the expansion of which is controllable by means of a pressurized fluid, for example with pressurized oil.
- the cylindrical wall 12 has a lower suction end 24 which is open and an upper end of the water inlet 26 also open.
- the upper end of the water inlet 26 here has two crossed structure members 28, 30 which respectively extend along a diameter of the cylindrical wall 12 and which make it possible, if necessary, to suspend the cylindrical wall 12. , the implementation of more than two structural members may then be necessary, to support precisely the cylindrical wall 12.
- the piston 14 is retained by a line 32 formed of a chain that extends from a loop of hooking 34 of the piston 14 substantially along the axis of symmetry A out to the outside of the cylindrical wall 12 through a passageway 36 formed at the intersection of the structural members 28, 30.
- means retaining means formed of four rods 38, 40, 42, 44, mounted facing each other in pairs and pivoted on the two structural members 28, 30 and which are adapted to grip at a point located on the axis of symmetry A, the c hain 32, allow to lock it in translation towards the lower suction end 24. In this way, the piston 14 is then kept suspended inside the cylindrical wall 12.
- the four links 38, 40, 42, 44 are adapted to release said chain 32 to allow the rise of the piston 14 to the upper end of the water inlet 26.
- the rods 38, 40, 42, 44 can be controlled by own means not shown or by means of an underwater robot.
- the piston 14 has a bore 46 which communicates the lower suction chamber 20 and the chamber opposite upper 22, this bore forming duct 46 is surmounted by pumping means not shown in this Figure 1.
- FIG. 2 in addition to the suction stack 10 that is found, a seabed 50 is shown diagrammatically and on the opposite side, a surface 52 corresponding to a certain height of water 54 in which the stack of water is dipped. suction 10.
- the suction pile 10 is thus in support vertically on the seabed 50 via its lower suction end 24 which is directly in contact with the sediments of the seabed 50.
- the piston 14 is then brought to a first height h1 which separates it from the seabed 50 by means of the chain 32 which is blocked by means of the retaining means 38, 40, 42, 44 of which only the links 38 and 40 appear in FIG. .
- This first height h1 corresponds to a water depth H below the surface 52, at which height of water H, the hydrostatic pressure is sufficiently large.
- the upper end of the water inlet 26 allows the water to fill the opposite upper chamber 22 in such a way that the piston 14 is subjected to the hydrostatic pressure which prevails near the seabed 50 and which corresponds to the said water height H.
- This hydrostatic pressure is obviously decreasing from the seabed 50 to the surface 52.
- the hydrostatic pressure that prevails near the seabed 50 induces E forces on the piston 14 which s' in one direction, oriented from the surface 52 towards the seabed 50, and which are transmitted to the cylindrical wall 12 via the chain 32, retaining means 38, 40, 42, 44 and structural members 28, 30..
- means for locking the piston 14 are formed by locks movably mounted on the piston and which engage in holes made in the inner surface 18 of the wall 12. In this way, said mobile locks are adapted to lock the piston 14 in translation relative to the cylindrical wall 12.
- the duct-forming bore 46 is here equipped with pumping means 56 which make it possible to draw the water contained in the lower suction chamber 20 to discharge it into the upper chamber 22 and to create a depression in the suction chamber. 20 to cause depression of the lower suction end 24 in the seabed 50.
- This depression is greatly accelerated by the efforts E which are exerted on the piston 14 and therefore on the cylindrical wall 12 along the axis of symmetry A and towards the seabed 50.
- the piston 14 can again be reassembled for a new suction operation. This can be done until the total insertion of the cylindrical wall 12 into the seabed 50. The piston 14 will then be located near the upper inlet end 26.
