Description

Technical Field

[0001] This invention relates to the field of piling equipment, and in particular to a construction vessel for shallow water areas and a method for moving the vessel thereon. Background Technology

[0002] A piling vessel is a type of offshore piling equipment used to install piles in the seabed. After the piles are installed, platforms for wind power generation and other operations can be installed on them. With the increasing number of maritime engineering projects in coastal areas, piling vessels are gradually developing towards larger sizes and greater automation to adapt to the construction of deep-water port terminals, cross-sea bridges, offshore wind power foundations, and other engineering projects.

[0003] However, many new energy equipment, such as photovoltaic systems, need to be developed in shallow sea areas, and an increasing number of projects are carrying out piling and other construction operations in these areas. When performing piling work in narrow, shallow waters, the limited space places specific demands on the piling vessel. Currently, some commonly used piling vessels, both domestically and internationally, meet the technical requirements for pile driving, such as length, inclination, and lifting weight. However, their large size, especially in narrow anchoring areas, can easily lead to collisions with oil terminals and oil trestles, affecting the normal entry and exit of vessels in tunnels and harbor basins. Other piling vessels are smaller, but their machinery, piling frames, and lifting systems cannot meet the project's piling technical requirements, making them unusable.

[0004] Currently, there are no dedicated construction vessels for small piling boats and small-scale engineering construction. Generally, land-based construction equipment (such as pile drivers, grab buckets, or vibratory hammers) is placed directly on barges for construction. However, these construction devices cannot meet the relevant marine construction specifications, and self-propelled barges are difficult to move in shallow water areas, resulting in low efficiency in anchoring and positioning. Therefore, it is necessary to develop dedicated construction vessels for shallow water areas. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of the prior art by providing a construction vessel and its movement method for shallow water areas, thereby improving the efficiency of construction in shallow water areas.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A construction vessel for shallow water areas, comprising:

[0008] hull;

[0009] The construction structure is located on the hull of the vessel.

[0010] The first pile body is movable through the hull and inserted into the seabed;

[0011] The second pile and the moving structure include a slider, a first driving member and a strip groove on the hull. The slider is slidably engaged with the strip groove. The second pile moves through the slider and inserts into the bottom of the water. The first driving member is connected to the hull and the slider respectively, and is used to drive the slider to move along the strip groove.

[0012] In one embodiment, the hull is provided with a plurality of retractable outriggers, which can be inserted into the seabed.

[0013] In one embodiment, the angle between the central axis of the support leg and the plane of the deck of the hull is an acute angle, and extends in a direction away from the hull.

[0014] In one embodiment, the first pile is distributed in the bow or stern region of the hull, and the second pile is correspondingly distributed in the stern or bow region of the hull. The sliding direction of the strip groove is parallel to the length direction of the hull. A portion of the legs are distributed on both sides of the first pile, and another portion of the legs are distributed on both sides of the second pile. When the legs shorten or extend, they provide a component force along the width direction of the hull to the hull.

[0015] In one embodiment, the outrigger is hinged to the hull, allowing the outrigger to rotate about the hinge axis. The hull is provided with a second driving member for driving the outrigger to rotate about the hinge axis.

[0016] In one embodiment, the second drive member includes a first piston cylinder hinged to the hull, and its output end hinged to the outrigger.

[0017] In one embodiment, the support leg includes a connecting rod, a second piston cylinder, and a base. The connecting rod is hinged to the hull, and the two ends of the second piston cylinder are respectively connected to the connecting rod and the base. The second driving member is disposed between the connecting rod and the hull.

[0018] In one embodiment, multiple moving structures are provided, and the multiple moving structures are arranged side by side along a direction perpendicular to the sliding direction of the slider.

[0019] In one embodiment, the first drive member includes a third piston cylinder disposed on the hull, and its output end is connected to the slider.

[0020] A method for moving a construction vessel, applied to the construction vessel, wherein in an initial state, a first pile passes through the hull and inserts into the seabed, and a second pile passes through a slider and inserts into the seabed, comprising the following steps:

[0021] The first pile has detached from the bottom of the water;

[0022] The first driving element controls the slider to move along the strip groove, thereby moving the hull;

[0023] The first pile is inserted into the bottom of the water, and the second pile is removed from the bottom of the water;

[0024] The first driving element controls the slider to move along the strip groove, so that the slider is reset;

[0025] The second pile passes through the slider and inserts into the bottom of the water.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. The aforementioned construction vessel for shallow water areas can insert the first and second piles into the seabed through the hull during construction operations, ensuring that the relative position of the hull and the construction site remains constant, thus improving the stability of the hull and construction efficiency. When the construction structure needs to change its operating position, the first pile is removed from the seabed, and then a first driving component drives a slider to move along a strip groove. Since the second pile is inserted into the water, it remains stationary relative to the water. The first driving component moves the hull closer to or away from the second pile, causing the second pile to move along the strip groove, thus enabling the hull to move on the water. This solves the problem of difficult movement of construction vessels in shallow water areas, avoids the need for anchoring for positioning, and improves the movement efficiency and construction efficiency of construction vessels in shallow water areas.

[0028] 2. The outriggers on the construction vessel are retractable. When the vessel is in operation, the outriggers can extend and insert into the seabed, further improving the stability of the vessel in conjunction with the first and second piles. When the vessel needs to move, the outriggers can retract and detach from the seabed, preventing them from hindering the vessel's movement.

[0029] 3. When the strip groove is set along the length or width of the hull, the second pile and the moving structure can only move the hull along its length or width. Therefore, the construction vessel is equipped with inclined outriggers. When the construction vessel needs to move along the width or length of the hull, the second pile can be inserted into the bottom of the water first, while the first pile is removed from the water. At this time, the extension or shortening of either leg on either side of the first pile provides a component force along the width or length of the hull to the end of the hull closest to the first pile, causing the hull to rotate around the second pile. Then, the first pile is inserted into the water, the second pile is removed from the water, and the extension or shortening of either leg on either side of the second pile causes the hull to rotate around the first pile. Finally, the second pile is inserted into the water, completing the movement of the construction vessel along its width.

[0030] 4. When the outriggers are hinged to the hull and a second drive unit connected to the hull is provided, the outriggers can drive the hull to move in a direction perpendicular to the hinge axis. The specific method of use is to detach the first and second piles from the bottom of the water, extend and insert multiple outriggers into the bottom of the water, and simultaneously drive multiple second drive units to extend or shorten, causing the outriggers to rotate relative to the hull. Since the bottom of the outriggers is fixed to the bottom of the water, the hull moves forward or backward a certain distance relative to the water in a direction perpendicular to the hinge axis, thus completing the movement of the hull and effectively improving the movement efficiency of the construction vessel.

[0031] 5. The construction vessel is equipped with multiple parallel moving structures, which can simultaneously pull the hull along the length of the strip groove to increase the moving force of the hull, while ensuring that the hull is subjected to uniform force and preventing the hull from deviating from the direction of movement.

[0032] 6. The moving structure uses a third piston cylinder to push the hull and the second pile to move relative to each other, which helps to improve the hull's propulsion power.

[0033] 7. Because the construction structure is detachably connected to the hull, the construction structure can be replaced according to construction needs, thus broadening the application range of the construction vessel. Attached Figure Description

Detailed Implementation

[0044] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.

[0045] The following describes in detail, with reference to the accompanying drawings, a construction vessel 100 for shallow water areas and its method of movement in some embodiments.

[0046] like Figures 1 to 7 As shown, in one embodiment, a construction vessel 100 for shallow water areas is provided, including a hull 10, a construction structure 20, a first pile 30, a second pile 40, and a movable structure 50;

[0047] The construction structure 20 is mounted on the hull 10, and the first pile 30 is movably inserted through the hull 10 and into the bottom of the water. The moving structure 50 includes a slider 52, a first driving member, and a strip groove 11 mounted on the hull 10. The slider 52 is slidably engaged with the strip groove 11, and the second pile 40 is movably inserted through the slider 52 and into the bottom of the water. The first driving member is connected to the hull 10 and the slider 52 respectively, and is used to drive the slider 52 to move along the strip groove 11.

[0048] The aforementioned construction vessel 100 for shallow water areas can insert the first pile 30 and the second pile 40 into the seabed through the hull 10 when the construction structure 20 is in operation. This ensures that the relative position of the hull 10 and the construction site remains unchanged during construction, improving the stability and efficiency of the hull 10. When the construction structure 20 needs to change its operating position, the first pile 30 is removed from the seabed, and then the first driving component drives the slider 52 to move along the strip groove 11. Since the second pile 40 is inserted into the water, it remains stationary relative to the water. The first driving component moves the hull 10 closer to or further away from the second pile 40, causing the second pile 40 to move along the strip groove 11. This enables the hull 10 to move on the water, solving the problem of difficult movement of the construction vessel 100 in shallow water areas, avoiding the need for anchoring for positioning, and improving the movement and construction efficiency of the construction vessel 100 in shallow water areas.

[0049] Specifically, if Figure 2 and Figure 4 As shown, in one embodiment, the first driving member includes a third piston cylinder 51, which is mounted on the hull 10 and its output end is connected to the slider 52. This moving structure 50 uses the third piston cylinder 51 to push the hull 10 and the second pile 40 to move relative to each other, which helps to improve the propulsion power of the hull 10.

[0050] Specifically, if Figure 2 and Figure 4 As shown, in one embodiment, multiple second piles 40 and multiple moving structures 50 are provided, with each second pile 40 corresponding to a moving structure 50. Multiple moving structures 50 are arranged side-by-side along a direction perpendicular to the sliding direction of the slider 52. The construction vessel 100 is provided with multiple parallel second piles 40 and moving structures 50, allowing the multiple moving structures 50 to simultaneously pull the vessel 10 along the length of the strip groove 11. This increases the moving force of the vessel 10 while ensuring uniform force distribution and preventing deviation in the moving direction of the vessel 10.

[0051] In this specific embodiment, there are two second pile bodies 40 and two moving structures 50. The length direction of the strip groove 11 is parallel to the length direction of the hull 10. The second pile bodies 40 and the first pile bodies 30 are arranged sequentially along the length direction of the hull 10. The second pile bodies 40 are located in the stern area and the first pile bodies 30 are located in the bow area. The two second pile bodies 40 are arranged sequentially along the width direction of the hull 10 and are referred to as the left moving pile 41 and the right moving pile 42. The moving structure 50 is located between the second pile bodies 40 and the first pile bodies 30.

[0052] In this invention, the width direction of the hull 10 refers to the direction in which the left and right sides of the hull 10 are arranged opposite each other, and the length direction of the hull 10 refers to the direction in which the bow and stern of the hull 10 are arranged opposite each other.

[0053] Figure 4 This is a schematic diagram of the construction vessel 100 moving forward along its length, as shown below. Figure 4 As shown, assuming the construction vessel 100 is in the first state, i.e., the third piston cylinder 51 is in the fully retracted state, and both the first pile 30 and the second pile 40 are inserted into the hull 10, the first pile 30 at the bow is first removed, the third piston cylinder 51 (the first driving component) is controlled to extend, the second pile 40 moves backward relative to the strip groove 11, and the hull 10 moves forward relative to the second pile 40, the construction vessel 100 is in the second state. Since the second pile 40 is inserted into the bottom of the water, the second pile 40 remains stationary relative to the water, and the hull 10 moves forward relative to the water. Then, the first pile 30 is inserted into the hull 10, the second pile 40 is pulled out, the third piston cylinder 51 is retracted and reset, and the second pile 40 is inserted again, the construction vessel 100 is in the third state, and the forward movement operation of the construction vessel 100 is completed.

[0054] Figure 5 This is a schematic diagram of the construction vessel 100 moving backward along its length, as shown below. Figure 5 As shown, when the construction vessel 100 is in the first state, the third piston cylinder 51 is in the fully extended state, and the first pile 30 and the second pile 40 are both inserted into the hull 10. At this time, the first pile 30 at the bow is pulled out, the third piston cylinder 51 is controlled to retract, the second pile 40 moves forward relative to the strip groove 11, and the hull 10 moves backward relative to the second pile 40, so that the construction vessel 100 is in the second state. Since the second pile 40 is inserted into the bottom of the water, the second pile 40 remains stationary relative to the water, and the hull 10 moves backward relative to the water. Then, the first pile 30 is inserted into the hull 10, the second pile 40 is pulled out, the third piston cylinder 51 is extended and reset, and the second pile 40 is inserted again, so that the construction vessel 100 is in the third state, thus completing the operation of moving the construction vessel 100 backward.

[0055] Specifically, if Figure 1 and Figure 2 As shown, in one embodiment, the hull 10 is provided with a plurality of retractable outriggers 60, which can be inserted into the seabed. The retractable outriggers 60 can be inserted into or removed from the seabed. When the outriggers 60 are extended, their bottoms are inserted into the seabed, cooperating with the first pile 30 and the second pile 40, further improving the stability of the construction vessel 100. When the construction vessel 100 needs to move, the outriggers 60 retract and detach from the seabed, preventing the outriggers 60 from affecting the movement of the construction vessel 100.

[0056] Furthermore, such as Figure 3 , Figure 6 and Figure 7 As shown, in one embodiment, the angle between the central axis of the support leg 60 and the plane where the deck of the hull 10 is located is an acute angle, and extends in a direction away from the hull 10.

[0057] The first pile 30 is distributed in the bow or stern region of the hull 10, and the second pile 40 is distributed in the stern or bow region of the hull 10. That is, the first pile 30 is distributed in the bow region of the hull 10, and the second pile 40 is distributed in the stern region of the hull 10, or the first pile 30 is distributed in the stern region of the hull 10, and the second pile 40 is distributed in the bow region of the hull 10. The sliding direction of the strip groove 11 is parallel to the length direction of the hull 10. A portion of the support legs 60 are distributed on both sides of the first pile 30, and another portion of the support legs 60 are distributed on both sides of the second pile 40. When the support legs 60 shorten or extend, they provide a component force along the width direction of the hull 10.

[0058] In this specific embodiment, the first pile 30 is distributed in the bow area of ​​the hull 10, the second pile 40 is distributed in the stern area of ​​the hull 10, and the support legs 60 are inclined along the width of the hull and away from the hull 10. Some of the support legs 60 are distributed on both sides of the first pile 30, and other support legs 60 are distributed on both sides of the second pile 40. Because the construction vessel 100 is equipped with inclined outriggers 60, when the construction vessel 100 needs to move along the width direction of the hull 10, the second pile 40 can be inserted into the bottom of the water first, and the first pile 30 can be removed from the bottom of the water. At this time, either outrigger 60 on both sides of the first pile 30 can be extended or shortened to provide a component force along its width direction to the end of the hull 10 near the first pile 30, causing the hull 10 to rotate around the second pile 40. Then, the first pile 30 can be inserted into the bottom of the water, and the second pile 40 can be removed from the bottom of the water. Either outrigger 60 on both sides of the second pile 40 can be extended or shortened to make the hull 10 rotate around the first pile 30. Finally, the second pile 40 can be inserted into the bottom of the water, completing the movement of the construction vessel 100 along the width direction.

[0059] Wherein, in the width direction of the hull 10, the angle α between the central axis of the support leg 60 and the plane on which the deck of the hull 10 is located is 30°~60°. Preferably, the angle α between the central axis of the support leg 60 and the plane on which the deck of the hull 10 is located is 45°.

[0060] In this specific embodiment, there are four support legs 60. Two support legs 60 are distributed on both sides of the first pile body 30. The support leg 60 on the left side of the first pile body 30 is designated as the first left support leg 65, and the support leg 60 on the right side of the first pile body 30 is designated as the first right support leg 66. The other two support legs 60 are distributed on both sides of the second pile body 40. The support leg 60 on the left side of the second pile body 40 is designated as the second left support leg 67, and the support leg 60 on the right side of the second pile body 40 is designated as the second right support leg 68.

[0061] like Figure 6As shown, the process of the construction vessel 100 moving to the right along the width direction is as follows: When the construction vessel 100 is in the first state, the left moving pile 41, the right moving pile 42, and the first pile body 30 are all inserted into the hull 10. The left moving pile 41 and the first pile body 30 are pulled out, and the right moving pile 42 passes through the hull 10 and inserts into the bottom of the water. At this time, the support legs 60 on both sides of the first pile body 30 are shortened or extended, that is, the first left support leg 65 is extended or the first right support leg 66 is shortened, providing a rightward offset force to the bow of the vessel, and the hull 10 moves around to the right. Pile 42 rotates to the right, hull 10 tilts, and construction vessel 100 is in the second state; then the first pile 30 is inserted, the right moving pile 42 is pulled out, and the legs 60 on both sides of the second pile 40 are controlled to shorten or extend, that is, the second left leg 67 extends or the second right leg 68 shortens, providing a rightward offset force to the bow, hull 10 rotates to the right around the first pile 30, hull 10 returns to center, construction vessel 100 is in the third state, left moving pile 41 and right moving pile 42 are inserted, and construction vessel 100 completes the rightward movement.

[0062] like Figure 7 As shown, the process of the construction vessel 100 moving to the left along the width direction is as follows: When the construction vessel 100 is in the first state, the left moving pile 41, the right moving pile 42, and the first pile body 30 are all inserted into the hull 10. The right moving pile 42 and the first pile body 30 are pulled out, and the left moving pile 41 passes through the hull 10 and inserts into the bottom of the water. At this time, the support legs 60 on both sides of the first pile body 30 are shortened or extended, that is, the first left support leg 65 is shortened or the first right support leg 66 is extended, providing a leftward offset force to the bow of the vessel, and the hull 10 moves around the left. Pile 41 rotates to the left, the hull 10 tilts, and the construction vessel 100 is in the second state; then the first pile 30 is inserted, the left moving pile 41 is pulled out, and the support legs 60 on both sides of the second pile 40 are controlled to shorten or extend, that is, the second left support leg 67 is shortened or the second right support leg 68 is extended, providing a leftward offset force to the bow, the hull 10 rotates to the left around the first pile 30, the hull 10 returns to the center, the construction vessel 100 is in the third state, the left moving pile 41 and the right moving pile 42 are inserted, and the construction vessel 100 completes the leftward movement.

[0063] Specifically, if Figure 2 and Figure 8As shown, in one embodiment, the support leg 60 is hinged to the hull 10, allowing the support leg 60 to rotate around the hinge axis. The hull 10 is equipped with a second driving member for driving the support leg 60 to rotate around the hinge axis. Specifically, the first pile 30 and the second pile 40 are detached from the waterbed, and multiple support legs 60 are extended and inserted into the waterbed. Simultaneously, the second driving member drives the support legs 60 to rotate relative to the hull 10. Since the bottom of the support leg 60 is fixed in the waterbed, the hull 10 moves forward or backward a certain distance relative to the water in a direction perpendicular to the hinge axis, completing the movement of the hull 10 and effectively improving the movement efficiency of the construction vessel 100. Generally speaking, using the second pile 40 and the moving structure to control the movement of the construction vessel 100 along its length is suitable for waters with a depth of about 15m, while using the outriggers 60 to control the movement of the construction vessel 100 along its length is suitable for waters with a depth of about 5m. Therefore, the outriggers 60 further broaden the water depth applicable to the construction vessel 100, enabling the construction vessel 100 to move in shallow waters of different depths.

[0064] The hinge axis can be parallel to either the length or the width direction, and the hinge axis of the support leg 60 is perpendicular to the sliding direction of the strip groove 11. When the support leg 60 rotates around the length direction of the hull 10, some of the support legs 60 are distributed at the bow end of the hull 10, and some of the support legs 60 are distributed at the stern end of the hull 10. The support legs 60 can rotate to move the hull 10 along the width direction. When the support leg 60 rotates around the width direction of the hull 10, some of the support legs 60 are distributed on the left side of the hull 10, and some of the support legs 60 are distributed on the right side of the hull 10. The support legs 60 can rotate to move the hull 10 along the length direction.

[0065] Furthermore, such as Figure 2 As shown, in one embodiment, the second driving member includes a first piston cylinder 61, which is hinged to the hull 10, and its output end is hinged to the support leg 60.

[0066] Furthermore, such as Figure 2 As shown, in one embodiment, the support leg 60 includes a connecting rod 62, a second piston cylinder 63, and a base 64. One end of the connecting rod 62 is hinged to the hull 10, and the other end of the connecting rod 62 is connected to the second piston cylinder 63. The output end of the second piston cylinder 63 is connected to the base 64, and the output end of the first piston cylinder 61 is circumferentially connected to the connecting rod 62.

[0067] In this specific embodiment, the support legs 60 rotate about the width of the hull 10. A portion of the support legs 60 are located on the left side of the hull 10, and another portion are located on the right side. The support legs 60 can rotate to move the hull 10 along its length. The specific movement process is as follows: Figure 8As shown, when construction is in its initial state, the left moving pile 41, the right moving pile 42, and the first pile body 30 are all detached from the bottom of the water, and the support legs 60 extend and insert into the bottom of the water. The support legs 60 are perpendicular to the length direction of the hull 10. The first piston cylinder 61 controls the extension of the four support legs 60. Since the bottom position of the support legs 60 is fixed, the first piston cylinder 61 drives the top of the support legs 60 to rotate with the hull 10, so that the hull 10 moves forward relative to the water and is in a forward state. At this time, the second piston cylinder 63 controls the retraction of the four support legs 60, so that the four support legs 60 are detached from the bottom of the water. Then the first piston cylinder 61 retracts to control the rotation of the support legs 60 to reset. Finally, the support legs 60 are controlled to extend and insert into the bottom of the water, completing the forward movement of the construction vessel 100.

[0068] When the construction vessel 100 moves backward, it is first brought to its initial state. Then, the first piston cylinder 61 of the four outriggers 60 is controlled to retract, and the four outriggers 60 rotate around the hinge axis. Since the bottom position of the outriggers 60 remains unchanged, the top of the outriggers 60 rotates with the hull 10, thereby moving the hull 10 backward relative to the water. The hull 10 is in a reversing state. At this time, the second piston cylinder 63 of the four outriggers 60 is controlled to retract, so that the four outriggers 60 are removed from the bottom of the water. Then, the first piston cylinder 61 is controlled to extend, keeping the outriggers 60 perpendicular to the length direction of the hull 10. Finally, the second piston cylinder 63 is controlled to extend and insert into the bottom of the water, completing the backward movement of the construction vessel 100.

[0069] Specifically, in one embodiment, the construction structure 20 is detachably connected to the hull 10, and the construction structure 20 includes a pile driver 22, a grab bucket, or a vibratory hammer. Because the construction structure 20 is detachably connected to the hull 10, the construction structure 20 can be replaced according to construction needs, thus broadening the applicability of the construction vessel 100.

[0070] Furthermore, in one embodiment, the hull 10 is provided with a rotating column 21, which can rotate around a vertical axis. The construction structure 20 is connected to the rotating column 21 through a flange, which is beneficial to improve the operational freedom of the construction structure 20 and facilitates the replacement of the construction structure 20, making it suitable for different construction scenarios.

[0071] like Figure 9 As shown, in one embodiment, a method for moving a construction vessel 100 is provided. The method applies to the construction vessel 100, which, in its initial state, has a first pile 30 passing through the hull 10 and inserted into the seabed, and a second pile 40 passing through a slider 52 and inserted into the seabed. The method includes the following steps:

[0072] The first pile 30 has detached from the bottom of the water;

[0073] The first driving component controls the slider 52 to move along the strip groove 11, causing the hull 10 to move;

[0074] The first pile 30 is inserted into the bottom of the water, and the second pile 40 is removed from the bottom of the water;

[0075] The first driving element controls the slider 52 to move along the strip groove 11, so that the slider 52 is reset;

[0076] The second pile 40 passes through the slider 52 and inserts into the bottom of the water.

[0077] Specifically, in one embodiment, the method for moving the construction vessel 100 includes moving it using outriggers 60 in a direction perpendicular to the hinge axis, comprising the following steps:

[0078] The left movable pile 41, the right movable pile 42 and the first pile body 30 all detached from the bottom of the water, and multiple support legs 60 extended and inserted into the bottom of the water;

[0079] A second driving component is used to control the rotation of multiple outriggers 60 around the hinge axis, causing the hull 10 to move;

[0080] Multiple outriggers retract 60 degrees and detach from the seabed;

[0081] A second driving component is used to control the rotation and reset of multiple support legs 60;

[0082] Multiple outriggers extend 60 degrees and insert into the bottom of the water.

[0083] Specifically, in one embodiment, the method for moving the construction vessel 100 includes moving it using the second pile 40, the first pile 30, and the outriggers 60, comprising the following steps:

[0084] The second pile 40 is inserted into the bottom of the water, while the first pile 30 is removed from the bottom of the water.

[0085] Control the extension or shortening of either leg 60 on both sides of the first pile 30 to make the hull 10 rotate around the second pile 40;

[0086] The first pile 30 is inserted into the bottom of the water, and the second pile 40 is removed from the bottom of the water. By controlling the extension or shortening of either leg 60 on both sides of the second pile 40, the hull 10 rotates around the first pile 30. The direction of rotation around the first pile 30 is opposite to the direction of rotation around the second pile 40.

[0087] The second pile 40 is inserted into the bottom of the water.

Therefore, they should not be construed as limitations on this invention.

[0089] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0090] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0091] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0092] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0093] The preferred embodiments of the present invention have been described in detail above.
