Description

Technical Field

[0001] This invention relates to the field of underwater leveling machine launching technology, and in particular to an underwater leveling machine transportation method and caisson transportation method based on a semi-submersible barge. Background Technology

[0002] An underwater screed is a type of machinery specifically designed for underwater earthwork leveling operations. It is widely used in marine engineering, water conservancy projects, and other fields. Through its unique design and structure, the underwater screed can effectively level soil underwater to achieve the desired smoothness.

[0003] Currently, underwater leveling machines are generally launched into the water by cranes. Because underwater leveling machines are wide in both the horizontal and vertical directions and are heavy, they require large crawler cranes or ship cranes for lifting and launching, resulting in very high launching costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that require large crawler cranes or ship cranes to lift and launch underwater leveling machines, resulting in very high launching costs. This invention provides a method for transporting underwater leveling machines and caissons based on a semi-submersible barge.

[0005] In a first aspect, the present invention provides a method for transporting an underwater leveling machine based on a semi-submersible barge, comprising the following steps: S1. Set up a support platform, place the underwater leveling machine on the support platform, and moor the semi-submersible barge against the seaward side of the support platform; S2. The underwater leveling machine moves onto the semi-submersible barge, and the semi-submersible barge drives the underwater leveling machine to the predetermined position; S3. The semi-submersible barge submerges, causing the underwater leveling machine to float, and the bottom of the underwater leveling machine detaches from the semi-submersible barge; the square barge is used to horizontally detach the underwater leveling machine from the semi-submersible barge, and the square barge lifts the underwater leveling machine and submerges it to the working position.

[0006] The underwater screed transportation method based on a semi-submersible barge described in this application relies on the underwater screed's own walking capability to carry out underwater screed launching operations using existing semi-submersible barges and square barges in dock construction. This eliminates the need to invest in additional, costly, and large-sized crawler cranes or ship cranes to lift the underwater screed into the water, thereby effectively reducing construction costs.

[0007] Preferably, the support platform has a recessed overlapping platform on the seaward side, and the semi-submersible barge has a protruding mounting platform that matches the overlapping platform at its front end. The surface of the support platform is flush with the top surface of the mounting platform.

[0008] Preferably, a flexible buffer structure is provided between the surface of the overlapping platform and the bottom surface of the overlapping plate.

[0009] Preferably, the underwater leveling machine is assembled on a support platform.

[0010] Preferably, the semi-submersible barge includes a semi-submersible barge platform, and a bow tower and a stern tower installed on the semi-submersible barge platform. When the semi-submersible barge is moored with the seaward side of the support platform, the bow tower is located between the support platform and the stern tower. At least two first winches are installed on the stern tower, and each first winch leads to a first aft cable. The first aft cable is connected to the end of the underwater leveling machine near the stern tower, and at least two first aft cables are arranged in a crisscross pattern. Preferably, at least two anchor winches are installed on the barge, and a front cable is extended from the anchor winch. The front cable is connected to one end of the underwater leveling machine near the barge, and at least two front cables are arranged in a cross configuration. The first rear cable and the front cable are both tensioned, and both the first rear cable and the front cable provide an upward vertical force to the underwater leveling machine.

[0011] Preferably, S3 specifically includes the following steps: S31. The semi-submersible barge drives the underwater leveling machine to the top of the submersible pit; S32. The semi-submersible barge descends to the submersion pit, causing the underwater leveling machine to detach vertically from the semi-submersible barge based on its own buoyancy; S33. Using the barge to drive the front cable, the underwater leveling machine is separated from the semi-submersible barge in the horizontal direction, and the first rear cable is extended simultaneously; S34. The barge uses the front cable to move the underwater leveling machine above the base bed; S35. Use the crane on the barge to lift the underwater leveling machine and lower it to the working position.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: The underwater screed transportation method based on a semi-submersible barge described in this application relies on the underwater screed's own walking capability to carry out underwater screed launching operations using existing semi-submersible barges and square barges in dock construction. This eliminates the need to invest in additional, costly, and large-sized crawler cranes or ship cranes to lift the underwater screed into the water, thereby effectively reducing construction costs.

However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0029] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

As long as the corresponding device / component / element can still achieve its function in the present invention within the error / deviation range, it is acceptable.

[0031] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0032] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0033] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly.

Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0034] Example 1 like Figures 1-15 As shown in this embodiment, an underwater leveling machine transportation method based on a semi-submersible barge includes the following steps: S1. Set up a support platform 100, assemble the underwater leveling machine 10 on the support platform 100, and moor the semi-submersible barge 200 to the seaward side of the support platform 100; S2. The underwater leveling machine 10 travels to the semi-submersible barge 200 and is transported to the vicinity of the base bed 600 via the semi-submersible barge 200; S3. The semi-submersible barge 200 submerges, causing the underwater leveling machine 10 to float, and the bottom of the underwater leveling machine 10 is separated from the semi-submersible barge 200; the square barge 700 is used to horizontally separate the underwater leveling machine 10 from the semi-submersible barge 200, and the square barge 700 lifts the underwater leveling machine 10 and submerges it to the working position.

[0035] The underwater leveling machine transportation method based on a semi-submersible barge described in this embodiment is based on a support platform 100 and relies on the underwater leveling machine 10's own walking ability. It can use semi-submersible barges and square barges to carry out the underwater leveling machine launching operation, so that there is no need to invest in a separate crawler crane or ship crane with high cost and large specifications to lift the underwater leveling machine into the water, thereby effectively reducing the construction cost of the dock.

[0036] A preferred embodiment: The semi-submersible barge includes a semi-submersible barge platform 210, and a head tower 202 and a tail tower 203 installed on the semi-submersible barge platform 210. When the semi-submersible barge 200 is moored with the seaward side of the support platform 100, the head tower 202 is located between the support platform 100 and the tail tower 203. At least two first winches 204 are installed on the tail tower 203. The first winch 204 leads out a first rear cable 205. The first rear cable 205 is connected to one end of the underwater leveling machine 10 near the tail tower 203. At least two first rear cables 205 are arranged in a cross pattern. At least two anchor winches 701 are installed on the barge 700. The anchor winches 701 have front cables 703 extending out from them. The front cables 703 are connected to the underwater leveling machine 10 near one end of the barge 700. At least two front cables 703 are arranged in a cross pattern. Both the first rear cable 205 and the front cable 703 are tensioned, and both the first rear cable 205 and the front cable 703 provide an upward vertical force to the underwater leveling machine 10.

[0037] A preferred embodiment: S3 specifically includes the following steps: S31. The semi-submersible barge 200 drives the underwater leveling machine 10 to above the submersible pit 400; S32. The semi-submersible barge 200 descends to the sinkhole 400, causing the underwater leveling machine 10 to detach vertically from the semi-submersible barge 200 based on its own buoyancy; S33. Using the barge 700 to drive the front cable 703, the underwater leveling machine 10 and the semi-submersible barge 200 are separated in the horizontal direction, and the first rear cable 205 is extended simultaneously. S34. The barge 700 uses the front cable 703 to move the underwater leveling machine 10 above the base bed 600; S35. Use the crane 702 on the barge 700 to lift the underwater leveling machine 10 and lower it to the working position.

[0038] A preferred embodiment: The semi-submersible barge 200 drives the underwater leveling machine 10 to the top of the submersible pit 400; The semi-submersible barge 200 descends to the submersion pit 400, causing the semi-submersible barge 200 and the underwater leveling machine 10 to vertically separate; The underwater leveling machine 10 is horizontally separated from the semi-submersible barge 200 by the barge 700. The process of submerging is also called surfacing.

[0039] The preferred structure of the support platform 100 is as follows: The support platform 100 includes several arrayed steel pipe piles 104 and a steel platform 103 supported on the upper part of the steel pipe piles 104. The support platform 100 has a recessed overlapping platform 102 on the seaward side. The support platform 100 is a high-pile pier structure, and is connected to the transport channel 301 and the storage area 300 at the rear. The front edge of the support platform 100 is 70-100m away from the front edge of the general berth. The elevation of the wharf platform is ≥2.4m. The overlapping platform 102 is used to overlap the semi-submersible barge 200, and the elevation of the overlapping platform 102 is ≥1.5m. A tail winch 208 is installed on the support platform 100, and a tail wire rope 209 is wound out of the tail winch 208. The preferred structure of the semi-submersible barge 200 includes a semi-submersible barge platform 210, a head tower 202, and a tail tower 203. When the semi-submersible barge 200 is moored with the seaward side of the support platform 100, the head tower 202 is closer to the support platform 100 than the tail tower 203. like Figure 10 As shown, the semi-submersible barge 200 has a protruding landing platform 201 adapted to the overlapping platform 102 at its front end. The surface of the steel platform 103 is flush with the top surface of the landing platform 201. A flexible buffer structure 101 is provided between the bottom surface of the landing platform 201 and the top surface of the overlapping platform 102. For example, the flexible buffer structure 101 is supported above the overlapping platform 102. The flexible buffer structure 101 is preferably a rubber pad with a thickness of ≥5cm to protect the surface of the overlapping platform 102.

[0040] In a preferred embodiment: a first winch 204 is installed on the tail tower 203, and a first rear cable 205 is led out from the first winch 204; a third winch 211 is installed on the head tower 202, and a second rear cable 216 is led out from the third winch 211.

[0041] In a preferred embodiment: at least two second winches 207 and traction pulley blocks are provided on the semi-submersible barge platform 210, and the second winches 207 are provided with second traction steel wire ropes 206; the second winches 207 are preferably located between the two tail towers 203 and are spaced apart.

[0042] The preferred structure of the submersible 400 is as follows: the dimensions of the submersible are: a width of 55m-60m, a length of 90m-110m, and a water depth of -18m to -22m.

[0043] The preferred structure of the barge 700 is as follows: the barge 700 is equipped with at least 3 anchor winches 701, at least 1 generator and at least 1 crane 702 to pull the underwater leveling machine 10 out of the barge, and the anchor winches 701 lead out the front cable 703.

[0044] Semi-submersible barge 200 docks with support platform 100: After the semi-submersible barge 200 is moored, it docks with support platform 100. The ballast water is adjusted so that the semi-submersible barge platform 210 of the semi-submersible barge 200 is flush with the support platform 100. That is, when docking, the upper surfaces of the semi-submersible barge platform 210 and the support platform 100 are at the same elevation.

[0045] like Figures 9-14 As shown, the self-propelled capability of the underwater leveling machine 10 is as follows: The underwater leveling machine described in this embodiment preferably includes a first main frame 2 and a second main frame 1. The first main frame 2 and the second main frame 1 achieve walking movement of the underwater leveling machine through at least four first vertical lifting legs 31 and at least four second vertical lifting legs 32, wherein: The first main frame 2 includes two spaced first longitudinal beams 22, and a first crossbeam 21 is connected between the ends of the two first longitudinal beams 22 on the same side; the second vertical lifting leg 32 is supported and connected to the first main frame 2. The second main frame 1 includes four arrayed end structures 13. A second longitudinal beam 12 connects adjacent end structures 13 longitudinally, and a second transverse beam 11 connects adjacent end structures 13 transversely. A first vertical lifting leg 31 is connected to the second transverse beam 11. Each end structure 13 has a first hole 131 extending through it along the length of the first longitudinal beam 22. A transverse frame 33 is installed within the first hole 131. The transverse frame 33 can slide with the first longitudinal beam 22 via a longitudinal telescopic mechanism 5. The transverse frame 33 slides with the end structure 13 along the length of the second transverse beam 11 via a transverse telescopic mechanism 4. The transverse frame 33 and the end structure 13 are relatively limited along the direction of the first longitudinal beam 22, preferably limited by a key and groove connection. The transverse frame 33 has a second hole 331 adapted to the first longitudinal beam 22 along the opening direction of the first hole 131. A transverse frame 33 is fitted onto the outside of the first longitudinal beam 22, which passes through and slides through the second hole 331. The second longitudinal beam 12 is fitted onto the outside of the first longitudinal beam 22 on the corresponding side, and the first longitudinal beam 22 can move relative to the second longitudinal beam 12 along its length. By providing a transverse frame 33 between the end structure 13 and the first longitudinal beam 22, the relative movement between the first longitudinal beam 22 and the end structure 13 along the longitudinal direction is achieved based on the sliding engagement between the first longitudinal beam 22 and the transverse frame 33. This achieves the purpose of the first vertical lifting leg 31 and the second vertical lifting leg 32 moving in a stepping manner. The second vertical lifting leg 32 is connected to the first longitudinal beam 22. Moreover, based on the sliding engagement with the end structure 13 along the radial direction of the first hole 131, the relative movement of the first longitudinal beam 22 and the end structure 13 along the radial direction of the first hole 131 is realized, thereby achieving the purpose of the first vertical lifting leg 31 and the second vertical lifting leg 32 moving in a stepping manner or correcting deviation along the length direction of the first hole 131.

[0046] The transverse frame 33 and the end structure 13 are restricted from sliding relative to each other along the length direction of the first hole 131 by a limiting structure, and the limiting structure does not restrict the transverse frame 33 from sliding relative to the end structure 13 radially along the first hole 131. However, when the first longitudinal beam 22 moves relative to the transverse frame 33 along the length direction of the first hole 131, there is no relative movement between the transverse frame 33 and the end structure 13, or the relative movement displacement is very small. The limiting structure preferably includes a matching groove and a slider. The groove is provided along the length direction of the second crossbeam 11, and one of the transverse frame 33 and the end structure 13 is provided with the groove, and the other is provided with the slider.

[0047] The end structure 13 has a first sidewall 132 located on one side of the first hole 131. A first gap 114 is provided between the transverse frame 33 and the first sidewall 132. A first through hole 133 is provided on the first sidewall 132. A first transverse support gantry 42 is connected to the outer wall of the first sidewall 132. A first transverse support 41 is connected to the transverse frame 33. The first transverse support 41 is located in the first gap 114. A transverse telescopic mechanism 4 is connected between the first transverse support gantry 42 and the first transverse support 41. The transverse telescopic mechanism 4 passes through the first through hole 133. The transverse telescopic mechanism 4 drives the transverse frame 33 to reciprocate relative to the end structure 13 by telescopically extending and retracting along the length direction of the second crossbeam 11. The transverse telescopic mechanism 4 can drive the transverse frame 33 away from or closer to the first sidewall 132, so as to achieve the purpose of the transverse frame 33 slidingly engaging with the end structure 13 radially along the first hole 131. The transverse telescopic mechanism 4 is preferably a telescopic hydraulic cylinder or a pneumatic cylinder.

[0048] A first longitudinal support 51 is connected to the transverse frame 33. The first longitudinal support 51 is preferably located within the first gap 114. A second longitudinal support 52 is connected to the first longitudinal beam 22. A longitudinal telescopic mechanism 5 is connected between the first longitudinal support 51 and the second longitudinal support 52. The longitudinal telescopic mechanism 5 can extend and retract along the length direction of the first longitudinal beam 22. The longitudinal telescopic mechanism 5 drives the first longitudinal beam 22 to slide and engage with the transverse frame 33 along the length direction of the first hole 131. The longitudinal telescopic mechanism 5 is preferably a telescopic hydraulic cylinder or a pneumatic cylinder.

[0049] The first longitudinal beam 22 is provided with a first vertical through hole 221. The second vertical lifting support leg 32 includes a second vertical telescopic mechanism 321 and a second vertical support gantry 223. The second vertical support gantry 223 is disposed above the first vertical through hole 221 and is detachably connected to the first longitudinal beam 22 by a pin or bolt group. The upper end of the second vertical telescopic mechanism 321 is connected to the second vertical support gantry 223, and the lower end is vertically slidingly engaged with the first vertical through hole 221. The second vertical telescopic mechanism 321 is preferably a hydraulic cylinder.

[0050] A support beam 115 protrudes from the side of the second crossbeam 11 near the first crossbeam 21. The support beam 115 has a second vertical through hole 116. A first vertical lifting leg 31 is connected to the support beam 115. The first vertical lifting leg 31 includes a first vertical telescopic mechanism 311 and a first vertical support gantry 117 located above the second vertical through hole 116. Both ends of the first vertical support gantry 117 are detachably connected to the support beam 115 via pins. The upper end of the first vertical telescopic mechanism 311 is connected to the first vertical support gantry 117, and the lower end slides vertically into the second vertical through hole 116. The first vertical telescopic mechanism 311 is preferably a hydraulic cylinder. The second vertical lifting leg 32 and the first vertical lifting leg 31 preferably have the same structure.

[0051] like Figure 1 As shown, the underwater leveling machine 10 is assembled on the support platform 100, with the following preferred configuration: Transfer the 10 components of the underwater leveling machine to the support platform 100; The assembly consists of a second main frame 1, a transverse sliding frame 33, a first vertical lifting support leg 31, and a transverse telescopic mechanism 4. Install the first longitudinal beam 22, which passes through the second longitudinal beam 12 and the end structure 13 on the same side. Install the second vertical lifting leg 32 on the first longitudinal beam 22, and then install the first cross beam 21. Install other parts on the underwater leveling machine 10.

[0052] like Figure 2 As shown, the underwater leveling machine 10 moving onto the semi-submersible barge 200 includes the following steps: The first vertical lifting outrigger 31 supports the underwater leveling machine 10, and the second vertical lifting outrigger 32 is separated from the support platform 100; Drive the first longitudinal beam 22 to move relative to the end structure 13 along the length direction of the first longitudinal beam 22; The second vertical lifting outrigger 32 descends and supports the underwater leveling machine 10; The first vertical lifting outrigger 31 rises and separates from the support platform 100; The drive end structure 13 moves relative to the first longitudinal beam 22 along the length direction of the first longitudinal beam 22; Repeat the above steps until the underwater leveling machine 10 moves onto the semi-submersible barge 200.

[0053] like Figure 3 As shown, each of the second vertical lifting legs 32 can be raised and lowered independently, and each of the first vertical lifting legs 31 can be raised and lowered independently. This means that the surfaces of the semi-submersible barge platform 210 and the support platform 100 do not need to be flush. It is sufficient that the elevation difference between the semi-submersible barge platform 210 and the support platform 100 is less than the vertical lifting limit distance of the first vertical lifting legs 31 and the second vertical lifting legs 32. This makes construction convenient and does not require the same alignment precision as when loading a caisson onto a barge, greatly reducing the difficulty of loading the barge onto the underwater leveling machine 10.

[0054] Based on the above, when the underwater leveler 10 is located on the semi-submersible barge platform 210, the first vertical lifting leg 31 and the second vertical lifting leg 32 can be lowered simultaneously, so that the underwater leveler 10 has 8 points of support. Compared with the four-point support of the first vertical lifting leg 31 or the second vertical lifting leg 32, the underwater leveler 10 is more stable.

[0055] More preferably, when the underwater leveler 10 is located on the semi-submersible barge platform 210, the first vertical lifting leg 31 or the second vertical lifting leg 32 abuts against the limiting iron block around its perimeter, and the limiting iron block is welded or bolted to the semi-submersible barge platform 210 to prevent relative sliding between the underwater leveler 10 and the semi-submersible barge platform 210 when the semi-submersible barge 200 is towed. Afterwards, when it is necessary to separate the underwater leveler 10 and the semi-submersible barge 200, the limiting iron block can be removed.

[0056] The first rear cable 205 is connected to the end of the underwater leveling machine 10 near the tail tower 203, and at least two first rear cables 205 are arranged in a cross pattern. At least two anchor winches 701 are installed on the barge 700. The anchor winches 701 have front cables 703 extending out from them. The front cables 703 are connected to the underwater leveling machine 10 near one end of the barge 700. At least two front cables 703 are arranged in a cross pattern. Both the first rear cable 205 and the front cable 703 are tensioned, and both the first rear cable 205 and the front cable 703 provide an upward vertical component force to the underwater leveler 10, so as to provide a relatively stable lateral and vertical drag force to the underwater leveler 10 and maintain the stability of the underwater leveler 10 in the water.

[0057] like Figures 5-8 As shown, in S5, the barge 700 uses the front cable 703 to move the underwater leveler 10 above the base bed 600. Then, the crane 702 on the barge 700 lifts the underwater leveler 10 and submerges it to the working position. It should be noted that the crane 702 on the barge 700 cannot directly lift the underwater leveler 10 from the shore into the water. When the underwater leveler 10 is on the semi-submersible barge 200, since the semi-submersible barge 200 is submerged at the submersion pit 400, the underwater leveler 10 floats on the water surface. At this time, the barge 700 uses the front cable 703 to move the underwater leveler 10 above the base bed 600. Throughout the entire process, the underwater leveler 10 is on the water surface, so that the load of the crane 702 is less than the weight of the underwater leveler 10, which can also achieve the purpose of assisting the underwater leveler 10 to submerge to the working position.

[0058] In a preferred embodiment, a compressed air drainage chamber 112 is provided inside the second crossbeam 11 for leveling the underwater leveler 10 underwater and controlling the buoyancy and descent of the underwater leveler 10.

[0059] The underwater leveling machine 10 has a preferred structure and buoyancy mechanism, such as the horizontal and vertical walking mechanism, multi-degree-of-freedom adjustable underwater leveling machine, and multi-degree-of-freedom adjustable underwater leveling machine in the construction method described in patent (publication number CN120139305A), wherein: Preferably, at least two compressed air drainage chambers 112 are provided inside the second crossbeam 11. Adjacent compressed air drainage chambers 112 are equipped with partitions 113, and the partitions 113 have water passage holes 118. The bottom of each compressed air drainage chamber 112 has inlet and outlet ports 119. Preferably, a sealing door can be provided at the inlet and outlet ports 119, which can be controlled to open or close, for example, with a waterproof electronic switch. Alternatively, a sealing door can be omitted at the inlet and outlet ports 119.

[0060] Buoyancy Explanation: Six compressed air drainage chambers 112 are arranged on each of the two second crossbeams 11, for a total of 12 compressed air drainage chambers 112 in the whole machine; the maximum buoyancy generated by the two second crossbeams 11 is about 50t; both the first longitudinal beam 22 and the first crossbeam 21 are equipped with sealed chambers, so that the first longitudinal beam 22 and the first crossbeam 21 can be used as pontoons, each generating about 20t of buoyancy. The total buoyancy generated by the second crossbeams 11, the first longitudinal beam 22 and the first crossbeam 21 is greater than the total weight of the underwater leveler 10, and the total buoyancy generated by the first longitudinal beam 22 and the first crossbeam 21 is less than the total weight of the underwater leveler 10.

[0061] In the above situation, the explanation for the whole machine sinking to the bottom and buoyancy assisting to rise from the water is as follows: Before lifting and launching, the overall status of the machine is as follows: the measuring tower 6 is laid down, the first longitudinal beam 22, the material placing pipe 7, the lateral movement mechanism, and the longitudinal movement mechanism are all in the center position. The lateral movement mechanism is used to drive the material placing pipe 7 to move laterally. The crane 702 has a main hook and an auxiliary hook. The main hook of the crane 702 is attached to the four lifting points on the two second crossbeams 11, and the auxiliary hook of the crane 702 is attached to the material placing pipe 7. The underwater machine is lifted to the designated position and placed on the water surface. The slings are loosened. At this time, the buoyancy of the whole machine is greater than its own weight, and it is in a floating state. At the same time, the exhaust valves of one compressed air drainage chamber 112 of each second crossbeam 11 are opened symmetrically to observe the water draft of the whole machine. When the leveling machine sinks, the exhaust valves are closed. The crane 702 is operated to slowly release the hooks until the leveling machine sinks to the bottom. After all the exhaust valves are opened to allow water to enter the compressed air drainage chamber 112, the operator controls the erection of the measuring tower 6 through the control box to carry out subsequent measurement, positioning, and leveling operations.

[0062] When the entire machine needs to be removed from the water, the measuring tower 6 is lowered, the main hook is hooked onto the slings of the four lifting points on the underwater leveling machine 10, and at the same time, the air inlet valves of one compressed air drainage chamber 112 on each second crossbeam 11 are opened symmetrically to compress air. After one chamber is drained, the current valve is closed, and then the air inlet valves of the next compressed air drainage chamber 112 on each crossbeam are opened symmetrically. The operation is repeated. During the drainage process, the lifting weight display screen of the crane 702 is observed. When the displayed lifting weight drops to the target value range, the exhaust valve is closed, and the hook is raised until the entire machine floats to the surface.

[0063] In the above scheme, the measuring tower 6 is installed on the end structure 13, and the underwater leveling machine 10 is also equipped with a drive mechanism that can drive the measuring tower 6 to swing. In this embodiment, the measuring tower 6 is installed on the end structure 13. During transportation, the measuring tower 6 is set to a horizontal position, which effectively reduces the impact of the measuring tower 6 on the center of gravity and eccentricity of the underwater leveling machine 10 during transportation. Then, when launching, the measuring tower is rotated from horizontal to vertical to adapt to the construction conditions. By rotating the measuring tower from horizontal to vertical, the safety of transporting the underwater leveling machine 10 can be effectively improved while adapting to the construction conditions. At the same time, during transportation or launching, the slight swing of the measuring tower 6 can be used to fine-tune the center of gravity of the underwater leveling machine 10, making construction safer. The drive mechanism can drive the measuring tower 6 to rotate from horizontal to vertical, and also drive the measuring tower 6 to rotate from vertical to horizontal. The drive mechanism is preferably a hydraulic cylinder.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
