Description

Technical Field

[0001] The present invention belongs to the technical field of immersed tube tunnel construction, and in particular relates to an integrated vessel for leveling a gravel bed for an immersed tube and transporting and sinking the same, and a method for constructing an immersed tube tunnel. Background Art

[0002] As a transportation method that strengthens connections between central urban areas and the outside world, inland river immersed tube tunnels play a vital role in supporting and guiding regional urban construction and development. Construction areas for inland river immersed tube tunnels are generally located on shallow, narrow inland waterways. This creates a narrow working surface, and if dedicated vessels are used for all construction processes, this can interfere with cable arrangements and the working surface.

[0003] To reduce the investment in specialized vessels during inland river immersed tube tunnel construction, patent CN116716933A discloses an integrated barge for gravel bed leveling and immersed tube sinking and installation. The barge integrates the functions of gravel bed leveling and immersed tube sinking and installation. The barge's hull is composed of two pontoons connected by two crossbeams. When transporting immersed tubes, the tubes are positioned between the two pontoons. The width of the barge's hull is greater than the width of the tubes it transports. However, the width of the barge's hull is limited by the width of the inland waterway, while the number of lanes and traffic volume of an immersed tube tunnel are determined by the width of the tubes. The wider the immersed tubes, the greater the traffic volume of the constructed immersed tube tunnel. Therefore, when the immersed tubes are wide, the required width of the barge may exceed the width of the inland waterway, making the tunnel unnavigable.

[0004] Therefore, how to reduce the width of the integrated ship and increase the width of the immersed tube that can be transported by the integrated ship while taking into account the integration of the gravel base leveling function and the immersed tube transportation and sinking function is a technical problem that needs to be solved urgently. Summary of the Invention

[0005] In response to the above technical problems, the present invention provides an integrated vessel for leveling the gravel base bed for immersed tubes and transporting and sinking, as well as an immersed tube tunnel construction method. The integrated vessel integrates the functions of leveling the gravel base bed and transporting and sinking immersed tubes. At the same time, the width of its hull does not need to be greater than the width of the immersed tubes it transports. It can transport immersed tubes with a width close to the upper limit of the inland waterway width, thereby maximizing the utilization of the inland waterway width.

[0006] The present invention provides an integrated vessel for leveling, transporting and sinking a subgrade of immersed tubes and gravel, comprising:

The cantilever beams extend from the single hull to the outside of the ship's side along the width direction of the single hull, and a pair of cantilever beams are respectively arranged near the bow of the single hull and near the stern of the single hull;

[0009] A leveling device is used to level the bed. The leveling device is mounted on the monohull and located between the two pairs of cantilever beams. The leveling device can be flipped in a vertical plane relative to the monohull to switch between an operating state and a non-operating state. In the operating state, the leveling device is in a vertical state and moves along the length of the monohull to perform the leveling operation. In the non-operating state, the leveling device is in a horizontal state.

[0010] The submerged tube lifting device includes sinking equipment arranged one-to-one corresponding to the cantilever beams. The sinking equipment is installed on the cantilever beams. Each sinking equipment is connected to the submerged tube located under the single hull to transport the submerged tube and control the sinking and installation of the submerged tube; wherein, the sinking equipment corresponding to the cantilever beams arranged in pairs are respectively connected to the two sides of the width direction of the submerged tube.

[0019] In some embodiments, a leveling operation window is opened in the middle of the single hull and passes through the single hull in the vertical direction. The length direction of the leveling operation window is consistent with the length direction of the single hull, and the width direction of the leveling operation window is consistent with the width direction of the single hull; there are two tracks, and the two tracks are symmetrically arranged on both sides of the width direction of the leveling operation window; the opposite sides of the constraint frame are connected to the two tracks through track wheels to move along the tracks, and the constraint frame and the leveling pipe are flipped relative to the track with the rotation axis of the track wheels as the axis. The length of the leveling operation window is greater than the total length of the leveling pipe and the leveling head, so that the leveling pipe can be flipped within the leveling operation window. When the leveling pipe is flipped to a vertical state, the leveling pipe is restricted to move within the leveling operation window; a second flipping drive component for driving the constraint frame and the leveling pipe to flip is connected between the single hull and the leveling pipe.

[0027] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0028] 1. The integrated vessel for leveling, transporting, and laying down submerged tubes and gravel beds provided by the present invention utilizes a single hull. A submerged tube hoisting device is mounted on the hull via a cantilever beam cantilevered outward from the ship's side. This allows the submerged tubes connected to the cantilever beam to fit snugly against the bottom of the hull for transport.

[0056] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0058] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0059] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0060] As attached Figures 1-11As shown in the first schematic embodiment of the submerged tube gravel bed leveling and transport and sinking integrated ship of the present invention, the submerged tube gravel bed leveling and transport and sinking integrated ship comprises a single hull 1, a leveling device 3, a submerged tube hoisting device and paired cantilever beams 2; the paired cantilever beams 2 are symmetrically arranged on both sides of the single hull 1 in the width direction, and the cantilever beams 2 are cantilevered from the single hull 1 to the outside of the ship's side along the width direction of the single hull 1, and a pair of cantilever beams 2 are respectively arranged near the bow of the single hull 1 and near the stern of the single hull 1; the leveling device 3 is used to level the base bed, and the part thereof carried on the single hull 1 and located between the two pairs of cantilever beams 2, the leveling device 3 can be relatively The single hull 1 is flipped in the vertical plane to switch between the working state and the non-working state; in the working state, the leveling device 3 is in a vertical state, and the leveling device 3 moves along the length direction of the single hull 1 to perform the leveling operation; in the non-working state, the leveling device 3 is in a horizontal state; the submerged tube hanging device includes a sinking device 4 arranged in a one-to-one correspondence with the cantilever beam 2, and the sinking device 4 is installed on the cantilever beam 2. Each sinking device 4 is jointly connected to the submerged tube 7 located under the single hull 1 to transport the submerged tube 7 and control the sinking and installation of the submerged tube 7; wherein, the sinking devices 4 corresponding to the cantilever beams 2 arranged in pairs are respectively connected to the two sides of the width direction of the submerged tube 7.

[0061] The working principle of the above-mentioned integrated ship for leveling the gravel base bed for sinking tubes and transporting and sinking is as follows: when leveling the gravel base bed, the leveling device 3 is flipped to the working state relative to the single hull 1, and the leveling device 3 moves along the length direction of the single hull 1 to perform the leveling operation; when transporting the submerged tube 7, the leveling device 3 is flipped to the non-working state relative to the single hull 1 to avoid the leveling device 3 interfering with the connection of the submerged tube 7. When connecting the submerged tube 7, the sinking equipment 4 corresponding to the pair of cantilever beams 2 arranged near the bow of the single hull 1 are respectively connected to the two sides of the axial end of the submerged tube 7 near the bow of the single hull 1, and the sinking equipment 4 corresponding to the pair of cantilever beams 2 arranged near the stern of the single hull 1 are respectively connected to the two sides of the other axial end of the submerged tube 7 near the stern of the single hull 1, and the top surface of the submerged tube 7 is attached to the bottom of the single hull 1 to fix the relative position of the submerged tube 7 and the single hull 1, thereby stably transporting the submerged tube 7.

[0062] The above-mentioned submerged tube gravel bed leveling and transport and sinking integrated vessel utilizes a single hull 1. A submerged tube hoisting device is mounted on a cantilever beam 2 cantilevered outward from the side of the hull 1, allowing the submerged tube 7 connected to the device to fit snugly against the bottom of the hull 1 for transport. The width of the transported submerged tube 7 can be greater than the combined width of the single hull 1 and its two cantilever beams 2. This allows for transporting submerged tubes 7 with a width approaching the upper limit of the inland waterway's width, maximizing the use of the inland waterway's width. Furthermore, in the above-mentioned submerged tube gravel bed leveling and transport and sinking integrated vessel, the leveling device 3 is mounted on the single hull 1 and located between the two pairs of cantilever beams 2. The provision of the cantilever beams 2 does not affect the operation of the leveling device 3. This increases the upper limit of the width of the transported submerged tube 7 while simultaneously integrating the gravel bed leveling and submerged tube transport and sinking functions.

[0063] For cantilever beam 2, if Figure 4 As shown, in this embodiment, the cantilever beam 2 has one end proximal to the monohull 1 as a lap end 22 and the other end as a cantilever end 21. The lap end 22 is lapped onto the monohull 1 and is formed with a diagonal brace 23 connected to the monohull 1. In this embodiment, the cantilever beam 2 is lapped onto the monohull 1 via the lap end 22. At the same time, the diagonal brace 23 strengthens the connection between the lap end 22 and the monohull 1, ensuring that the connection strength between the cantilever beam 2 and the monohull 1 meets the force requirements for connecting the submerged tube 7. Preferably, the cantilever beam 2 is detachably connected to the monohull 1, allowing for selection of a cantilever beam 2 of appropriate length based on the width of the submerged tube 7 to be transported.

[0064] like Figure 4 As shown, in this embodiment, the sinking equipment 4 includes a sinking winch 41, a sinking cable 42 and a fixed pulley 43. The sinking winch 41 is arranged on the overlapping end 22 of the cantilever beam 2, and the fixed pulley 43 is arranged on the cantilever end 21 of the cantilever beam 2. One end of the sinking cable 42 is wound around the sinking winch 41, and the other end passes around the fixed pulley 43 and then extends downward to connect to the immersed tube 7. Setting the fixed pulley 43 at the cantilever end 21 of the cantilever beam 2 can maximize the distance between the two connection points in the width direction of the immersed tube 7, thereby maximizing the width of the transported immersed tube 7. At the same time, setting the sinking winch 41 at the overlapping end 22 is conducive to reducing the force on the cantilever beam 2. It should be noted that in order to facilitate the installation of the fixed pulley 43, as shown in FIG. Figure 4 As shown, in this embodiment, the cantilever end 21 of the cantilever beam 2 is provided with a hanging opening a that passes through the cantilever beam 2 from top to bottom, the fixed pulley 43 is installed at the hanging opening a, and the sinking cable 42 extends downward through the hanging opening a to connect to the immersed tube 7.

[0065] like Figure 1 and Figure 4As shown, the vessel for leveling the submerged tube gravel bed, transporting and sinking also includes a mooring system. The mooring system includes mooring equipment 5 located near the four corners of the monohull 1. The mooring equipment 5 includes a mooring winch 51 and a mooring cable 52. The mooring winch 51 is located on the monohull 1. One end of the mooring cable 52 is wound around the mooring winch 51 and the other end is anchored to the water bottom. The mooring system can be used to fix the position of the vessel for leveling the submerged tube gravel bed, transporting and sinking during construction.

[0066] like Figure 4 As shown, a pair of cantilever beams 2 located near the bow and a pair of cantilever beams 2 located near the stern of the monohull 1 correspond one-to-one with the mooring devices 5 located at the four corners of the monohull 1. In these corresponding cantilever beams 2 and mooring devices 5, the cantilever beams 2 are located on the outside of the monohull 1 in the longitudinal direction, while the mooring devices 5 are located on the inside of the monohull 1 in the longitudinal direction. A clearance b is formed between the diagonal bracing portion 23 of the cantilever beams 2 and the end surface of the cantilevered end 21 thereof, allowing the mooring cable 52 to pass through. This arrangement allows the cantilever beams 2 to be as close as possible to the bow and stern of the monohull 1, thereby maximizing the distance between the connection points along the longitudinal direction of the immersed tube 7. This helps maintain force balance on the monohull 1 during transportation, while also maximizing the length of the transported immersed tube 7. Furthermore, by providing the clearance b in the cantilever beams 2 for the mooring cable 52 to pass through, interference between the mooring cable 52 and the cantilever beams 2 is avoided.

[0067] In order to avoid collision and friction between the submerged tube 7 and the bottom of the single hull 1, Figure 11 As shown, a buffer pad 8 is provided at the bottom of the single hull 1 for buffering collision and friction between the immersed tube 7 and the bottom of the single hull 1 .

[0068] like Figure 1 、 Figure 5-Figure 9As shown, the leveling device 3 includes a track 31, a constraint frame 33, a leveling pipe 34 and a leveling head 35; the track 31 is laid on the single hull 1 along the length direction of the single hull 1; the constraint frame 33 is movably connected to the track 31 to move along the track 31, and can be flipped in the vertical plane relative to the single hull 1; the leveling pipe 34 is passed through the constraint frame 33 to move and flip synchronously with the constraint frame 33; the leveling head 35 is connected to one axial end of the leveling pipe 34; when in working state, the leveling pipe 34 is in a vertical state and the leveling head 35 is located at the bottom end of the leveling pipe 34, and the leveling pipe 34 can be raised and lowered relative to the constraint frame 33; when in non-working state, the leveling pipe 34 is in a horizontal state. In the leveling device 3, the leveling head 35 is driven by the lifting of the leveling tube 34 to level the corresponding position below the leveling head 35. The lifting direction of the leveling tube 34 is constrained by the constraint frame 33 to maintain the verticality of the leveling tube 34. The leveling tube 34 is driven by the constraint frame 33 to move along the track 31 to change the leveling operation position. The leveling tube 34 is driven by the constraint frame 33 to flip in the vertical plane relative to the single hull 1 to realize the switching of the leveling device 3 between the working state and the non-working state. It should be noted that, if Figure 1 As shown, the track 31 is located between the two pairs of cantilever beams 2 at the bow and the stern, so that the leveling device 3 works between the two pairs of cantilever beams 2 at the bow and the stern.

[0069] like Figure 1 、 Figure 5 and Figure 6 As shown, a track 31 is provided near one side of the ship's side of the single hull 1, and a constraint frame 33 is connected to the track 31 via a mobile trolley 32. The mobile trolley 32 is movably connected to the track 31 to drive the constraint frame 33 to move along the track 31. The constraint frame 33, the leveling pipe 34, and the leveling head 35 are all located on the outer side of the ship's side of the single hull 1. The constraint frame 33 is rotatably connected to the mobile trolley 32. A first flipping drive assembly 38 for driving the constraint frame 33 to flip on the outer side of the ship's side relative to the mobile trolley 32 is connected between the constraint frame 33 and the mobile trolley 32. In this embodiment, the constraint frame 33 is connected to the outer side of the ship's side of the single hull 1 by the provided mobile trolley 32. The constraint frame 33 and the mobile trolley 32 are connected in a rotational manner, so that the constraint frame 33 is driven to rotate relative to the mobile trolley 32 by the first flipping drive assembly 38, so that the constraint frame 33 drives the leveling pipe 34 and the leveling head 35 to flip. In this embodiment, the constraint frame 33 drives the leveling pipe 34 and the leveling head 35 to perform leveling operations and flipping on the outside of the side of the single hull 1. The working space and flipping space are both large, and the single hull 1 can adopt a conventional hull structure without the need for additional customization.

[0070] like Figure 6-Figure 9As shown, the constraint frame 33 is rotatably connected to the mobile trolley 32 through the rotating shaft 331. The axis of the rotating shaft 331 is arranged along the width direction of the single hull 1 and is perpendicular to the axis of the leveling tube 34. The first flip driving assembly 38 includes a swing arm 381 and a telescopic member 382. One end of the swing arm 381 is fixedly connected to the outer periphery of the rotating shaft 331. The swing arm 381 extends from the outer periphery of the rotating shaft 331 to one side of the rotating shaft 331 along the radial direction of the rotating shaft 331. The telescopic member 382 is located on one side of the rotating shaft 331 and is in the same position as the swing arm 381. On the same side, one end of the telescopic member 382 is hinged to the mobile trolley 32, and the other end of the telescopic member 382 is hinged to the end of the swing arm 381 away from the rotating shaft 331. The telescopic member 382 is extended and retracted in a vertical plane perpendicular to the axis of the rotating shaft 331 to drive the swing arm 381 to drive the rotating shaft 331 to swing between a first position and a second position around the axis of the rotating shaft 331. When the swing arm 381 is in the first position, the leveling tube 34 is in a vertical state, and when the swing arm 381 is in the second position, the leveling tube 34 is in a horizontal state. The above-mentioned first flip drive assembly 38 is used to swing the swing arm 381 through the extension and retraction of the telescopic member 382, ​​and the swing arm 381 then drives the rotating shaft 331 to rotate, thereby realizing the flipping of the constraint frame 33 relative to the mobile trolley 32. The first flip drive assembly 38 has a simple structure and is convenient for driving the constraint frame 33 to flip relative to the mobile trolley 32.

[0071] In order to facilitate the connection of the rotating shaft 331 to the mobile trolley 32, and at the same time, to facilitate the installation of the first flip drive assembly 38, as shown in FIG. Figure 6-Figure 9 As shown, a connecting frame 37 is provided on the side of the mobile trolley 32 facing the constraint frame 33, and the connecting frame 37 includes a bottom plate 371, a first vertical frame 372 and a second vertical frame 373 arranged on the bottom plate 371, and a top frame 375 connected between the top of the first vertical frame 372 and the top of the second vertical frame 373; the first vertical frame 372 is located on the side away from the mobile trolley 32, and the first vertical frame 372 is provided with a first rotating shaft connecting plate 3721, and the second vertical frame 373 is located on the side close to the mobile trolley 32, and the second vertical frame 373 is provided with a first rotating shaft connecting plate 3721. The second rotating shaft connecting plate 3731 opposite to the connecting plate 3721, the rotating shaft 331 is fixedly connected to the side of the constraint frame 33 facing the moving trolley 32, and the rotating shaft 331 passes through and rotates to be connected to the first rotating shaft connecting plate 3721 and the second rotating shaft connecting plate 3731 in sequence; the swing arm 381 is connected to the outer periphery of the part of the rotating shaft 331 located between the first rotating shaft connecting plate 3721 and the second rotating shaft connecting plate 3731; the bottom end of the telescopic member 382 is hinged to the bottom plate 371, and the top end of the telescopic member 382 is hinged to the end of the swing arm 381 away from the rotating shaft 331. In this embodiment, the first vertical frame 372 and the second vertical frame 373 of the connecting frame 37 provide connection support points for the connection of the rotating shaft 331. At the same time, the space formed between the bottom plate 371, the first vertical frame 372, the second vertical frame 373 and the top frame 375 of the connecting frame 37 provides installation space for the first flip drive assembly 38. Further, as Figure 8 As shown, the upper portion of the connecting frame 37 protrudes from the top surface of the movable trolley 32, and a diagonal brace 374 is connected between the upper portion of the connecting frame 37 and the top surface of the movable trolley 32. The diagonal brace 374 can strengthen the connection strength between the connecting frame 37 and the movable trolley 32, and resist the tensile force exerted on the connecting frame 37 due to the connection with the restraining frame 33 via the rotating shaft 331.

[0072] In order to ensure that the connection strength between the swing arm 381 and the rotating shaft 331 is sufficient to drive the rotating shaft 331 to rotate, as shown in FIG. Figure 9 As shown, the swing arm 381 includes a fixed portion 3811 sleeved on the outer periphery of the rotating shaft 331, and a swing portion 3812 connected to the fixed portion 3811 and extending outward from the outer periphery of the rotating shaft 331 along the radial direction of the rotating shaft 331. In order to facilitate the swing arm 381 to swing by the telescopic member 382, ​​as shown in FIG. Figure 9 As shown, the extension direction of the swing portion 3812 is set at an angle to the vertical direction so that the swing portion 3812 is located on the side of the rotation shaft 331, and the telescopic member 382 is located on one side of the rotation shaft 331 and on the same side as the swing portion 3812. Further, in order to facilitate the hinged connection between the swing arm 381 and the telescopic member 382, ​​as shown in FIG. Figure 7 As shown, there are two swing arms 381, and the swing parts 3812 of the two swing arms 381 extend in the same direction and are arranged opposite to each other. A hinge column 383 for hingedly connecting the telescopic member 382 is connected between the ends of the swing parts 3812 of the two swing arms 381 away from the fixed part 3811. In addition, as Figure 7 As shown, the telescopic member 382 is preferably a hydraulic telescopic rod.

[0073] In addition, if Figure 5 As shown, the leveling actuator further includes a lifting assembly 36 for driving the leveling tube 34 to rise and fall relative to the restraining frame 33 when the leveling tube 34 is in a vertical position. The lifting assembly 36 includes a lifting rope 362 for pulling the leveling tube 34 up and down, and a lifting winch 361 for retracting and releasing the lifting rope 362. The lifting winch 361 is mounted on the end of the mobile trolley 32 away from the restraining frame 33, and the lifting rope 362 is connected between the lifting winch 361 and the leveling tube 34. In this embodiment, the lifting winch 361 retracts and releases the lifting rope 362 to drive the leveling tube 34 up and down, thereby achieving the leveling operation. Furthermore, in this embodiment, the lifting winch 361 is mounted on the end of the mobile trolley 32 away from the restraining frame 33, acting as a counterweight, which helps maintain the balance of the mobile trolley 32. This eliminates the need for a reserved mounting location for the lifting winch 361 on the restraining frame 33, thereby reducing the size and weight of the restraining frame 33.

[0074] Based on the above-mentioned integrated ship for leveling the gravel bed of immersed tubes and transporting and sinking, Figure 10 and Figure 11As shown, the present invention also provides a method for constructing an immersed tube tunnel, which uses the above-mentioned immersed tube gravel bed leveling and transport and sinking integrated ship to perform gravel bed leveling construction and immersed tube transportation and sinking construction;

[0075] The gravel bed leveling construction includes: adjusting the direction of the integrated ship so that the length direction of the single hull 1 is perpendicular to the extension direction of the gravel bed 6 to be leveled, moving the integrated ship to the first working position at one end of the gravel bed 6 to be leveled, flipping the leveling device 3 in the vertical plane relative to the single hull 1 to the working state, and moving the leveling device 3 along the length direction of the single hull 1 to complete the leveling operation at the current working position; gradually moving the integrated ship toward the other end of the gravel bed 6 to the next working position, and performing the leveling operation at each working position using the leveling device 3 until the leveling operation of the gravel bed 6 is completed;

[0076] The construction of transporting and sinking the immersed tube includes: making the immersed tube 7 sit on the bottom in a dry dock filled with water, flipping the leveling device 3 of the integrated ship to a non-working state in the vertical plane relative to the single hull 1, the integrated ship entering the dry dock and taking position above the immersed tube 7, adjusting the direction of the integrated ship so that the length direction of the single hull 1 is consistent with the length direction of the immersed tube 7 when in position, connecting the immersed tube 7 through a immersed tube lifting device, and lifting the immersed tube 7 through the immersed tube lifting device so that the immersed tube 7 fits the bottom of the single hull 1, transporting the immersed tube 7 to the preset sinking position by the integrated ship, and using the immersed tube lifting device to sink the immersed tube 7 onto the gravel base bed 6.

[0077] As attached Figures 12-18As shown, in order to keep the single hull 1 balanced, in the second schematic embodiment of the submerged tube gravel bed leveling and transport and sinking integrated ship of the present invention, the leveling device 3 is carried in the center position of the single hull 1, specifically: a leveling operation window c is opened in the middle of the single hull 1 and passes through the single hull 1 in the vertical direction, the length direction of the leveling operation window c is consistent with the length direction of the single hull 1, and the width direction of the leveling operation window c is consistent with the width direction of the single hull 1; there are two tracks 31, and the two tracks 31 are symmetrically arranged on both sides of the width direction of the leveling operation window c; the relative Each side is connected to two tracks 31 via track wheels 332 for movement along the tracks 31. The constraint frame 33 and leveling tube 34 rotate relative to the tracks 31 about the rotation axis of the track wheels 332. The length of the leveling operation window c is greater than the combined length of the leveling tube 34 and leveling head 35, allowing the leveling tube 34 to rotate within the leveling operation window c. When the leveling tube 34 is tilted to a vertical position, its movement is restricted within the leveling operation window c. A second tilting drive assembly 39 is connected between the single hull 1 and the leveling tube 34 to drive the constraint frame 33 and leveling tube 34 to rotate. In this embodiment, by providing a leveling operation window c in the middle of the single hull 1, the leveling device 3 is installed within the leveling operation window c, which helps maintain the balance of the single hull 1. It should be noted that the leveling operation window c is located between the two pairs of cantilever beams 2 at the bow and stern.

[0078] like Figure 15 and Figure 16 As shown, in this embodiment, the track 31 is detachably connected to a stopper 311 for securing the position of a track wheel 332 when the restraining frame 33 is tilted. The second tilting drive assembly 39 includes a tilting winch 391 and a tilting traction rope 392. The tilting winch 391 is mounted on the monohull 1. One end of the tilting traction rope 392 is wound around the tilting traction rope 392 and the other end is connected to the end of the leveling tube 34 away from the leveling head 35. In this embodiment, the track wheel 332 is secured by the stopper 311. The tilting winch 391 then retracts and releases the tilting traction rope 392 to drive the leveling tube 34 to tilt about the axle of the fixed track wheel 332. This simple tilting structure facilitates the control of the leveling tube 34's tilting. It should be noted that in this embodiment, two track wheels 332 are connected to each track 31. When the leveling tube 34 is tilted, one of the track wheels 332 is secured by the stopper 311. It should also be noted that in this embodiment, the limiting member 311 comprises two limiting blocks that are clamped to the track 31. The two limiting blocks respectively abut against the two sides of the track wheel 332 to fix the position of the track wheel 332. Furthermore, it should be noted that the turning winch 391 is disposed near one end of the leveling operation window c in the longitudinal direction to facilitate turning the leveling tube 34.

[0079] like Figure 17 and Figure 18As shown, the process of performing gravel base leveling construction and immersed tube transportation and sinking construction using the immersed tube gravel base leveling and transportation and sinking integrated vessel provided by the second exemplary embodiment of the present invention is the same as that of the first exemplary embodiment.
