Description

Technical Field

[0001] The utility model relates to the technical field of underwater construction, in particular to an underwater base bed leveling frame. Background Art

[0002] The construction of submarine immersed tube tunnels or port caisson terminals places high demands on the subgrade for the installation of the tubes and caissons. Typically, a construction process involving trench excavation and stone dumping is employed, with manual leveling or underwater leveling typically performed by leveling vessels. Due to the influence of wind and wave conditions in the construction area, the quality of the subgrade cannot meet construction requirements, resulting in low leveling efficiency. Leveling vessels have poor adaptability to tidal heights, leading to high construction costs. Furthermore, using underwater leveling equipment requires lifting the leveling frame from underwater using a crane vessel, which reduces construction efficiency. Utility Model Content

[0003] In view of the above defects in the prior art, the present invention provides an underwater base bed leveling frame to solve the problem that the leveling frame of the existing underwater leveling device needs to be lifted from underwater by a crane ship.

[0004] The utility model is implemented by the following technical solutions:

[0005] An underwater base bed leveling frame includes two oppositely arranged transverse tubes and two oppositely arranged longitudinal tubes. The two transverse tubes and the two longitudinal tubes form a leveling frame. Each transverse tube and / or each longitudinal tube is provided with a plurality of spaced-apart watertight bulkheads along its respective extension direction. Each watertight bulkhead divides the internal space of each transverse tube and / or each longitudinal tube into a plurality of compartments. Each compartment is provided with an air inlet for transmitting compressed air to the compartment and a drain outlet for draining water. Each air inlet is connected to an air inlet device, and the drain outlet is provided with a drain stop valve.

[0006] Furthermore, it also includes a pipeline connecting the air inlet and the air intake device, and the air inlet is provided with an air intake stop valve for controlling the air intake of the cabin.

[0007] Furthermore, the air intake stop valve is an electric remote control stop valve or an automatic stop valve.

[0008] Furthermore, the air intake device is an air compressor that comes with the ship or an air compressor that is independent of the ship.

[0009] Furthermore, the drainage stop valve is an electric remote-controlled stop valve or an automatic stop valve.

[0010] Furthermore, a maintenance port is provided on each cabin.

[0011] Furthermore, each transverse tube and / or each longitudinal tube is provided with a lifting lug on its exterior.

[0012] Furthermore, the end of the transverse tube is detachably connected to the end of the longitudinal tube.

[0013] Furthermore, the transverse tube and the longitudinal tube are both formed by splicing a plurality of circular tubes.

[0014] Furthermore, telescopic legs are respectively provided at the four corners of the bottom of the leveling frame, and a telescopic hydraulic cylinder is provided inside the telescopic legs.

[0015] Compared with the prior art, the beneficial effects of the present invention include at least:

[0016] The present invention provides a plurality of watertight bulkheads spaced apart within the interior spaces of the transverse and longitudinal tubes, thereby forming a plurality of compartments within the interior spaces of the transverse and longitudinal tubes. An air intake device inflates the compartments through the air inlets, and compressed air is used to forcibly discharge the water within the compartments through the drain outlets, thereby increasing the buoyancy of the leveling frame, allowing the entire apparatus to float on the water surface. The leveling frame is lifted by inflation, eliminating the need for a crane to lift the leveling frame from underwater, resulting in greater flexibility. Furthermore, because the leveling frame has multiple compartments, it can maintain a balanced and stable float during inflation. Compared to conventional leveling frames that only have buoyancy chambers within the transverse tubes, the leveling frame of the present invention is more stable and less prone to capsizing. Furthermore, the watertight bulkheads tightly separate the compartments. During the floatation process, even if one or two compartments are damaged and flooded, the water will not flow into the other compartments. Thus, the leveling frame still maintains considerable buoyancy, ensuring smooth floating. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make this disclosure more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. Identical reference numerals in the figures denote identical or similar structures, and thus repeated descriptions thereof will be omitted.

[0021] The words expressing positions and directions described in this utility model are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of this utility model.

[0022] like Figure 1 and Figure 2 As shown, an underwater base bed leveling frame provided by the utility model includes two oppositely arranged transverse tubes 101 and two oppositely arranged longitudinal tubes 102. The two transverse tubes 101 and the two longitudinal tubes 102 enclose a leveling frame 10. A plurality of spaced-apart watertight bulkheads 103 are provided in each transverse tube 101 and / or each longitudinal tube 102 along their respective extension directions. Each watertight bulkhead 103 divides the internal space of each transverse tube 101 and / or each longitudinal tube 102 into a plurality of compartments 104. Each compartment 104 is provided with an air inlet 105 for transmitting compressed air to the compartment 104 and a drain outlet 106 for draining water. Each air inlet 105 is connected to an air inlet device, and the drain outlet 106 is provided with a drain stop valve.

[0023] In this embodiment, multiple watertight bulkheads 103 are provided at intervals within the interior spaces of the transverse tubes 101 and longitudinal tubes 102, thereby forming multiple compartments 104 within the interior spaces of the transverse tubes 101 and longitudinal tubes 102. An air intake device inflates the compartments 104 through air inlets 105, forcing the water within the compartments 104 out through drains 106 using compressed air. This increases the buoyancy of the leveling frame 10, allowing the entire apparatus to float on the water surface. The leveling frame 10 is raised through inflation, eliminating the need for a crane to lift the leveling frame from underwater, resulting in greater flexibility. Furthermore, because the leveling frame 10 has multiple compartments 104, it can maintain a stable and balanced float during inflation. Compared to conventional leveling frames that only have buoyancy chambers within the transverse tubes 101, the leveling frame 10 of the present invention is more stable and less prone to capsizing. Secondly, the watertight bulkheads 103 strictly separate the cabins 104 from each other. During the floating process, even if one or two cabins 104 are damaged and flooded, the water will not flow into other cabins 104. In this way, the leveling frame 10 still maintains considerable buoyancy, ensuring that the leveling frame can float smoothly.

[0024] As a preferred embodiment, a pipeline is further included to connect the air inlet 105 and the air intake device, and the air inlet 105 is provided with an air intake shut-off valve for controlling the air intake of the cabin 104 .

[0025] As a preferred embodiment, the air inlet stop valve is an electric remote control stop valve, or an automatic stop valve. Using an electric control method, the inflation of the cabin 104 can be remotely controlled, which is more convenient and flexible.

[0026] In a preferred embodiment, the air intake device is a vessel's own air compressor or an air compressor independent of the vessel. In this embodiment, the air intake device is a machine that provides compressed air to cabin 104. The vessel's own air compressor can be connected to air inlet 105 via piping. If the vessel is not equipped with an air compressor or a separate air compressor is required for reliability, this can be optionally configured in the present invention.

[0027] As a preferred embodiment, the drainage stop valve is an electric remote control stop valve or an automated stop valve, so that the drainage of the cabin 104 can be remotely controlled.

[0028] As a preferred embodiment, a maintenance port 107 is also provided on each cabin 104. In this way, the internal structure of the cabin 104 can be inspected through the maintenance port.

[0029] As a preferred embodiment, a lifting lug 108 is provided on the outside of each transverse tube 101 and / or each longitudinal tube 102 .

[0030] In this embodiment, after the leveling frame floats on the water surface, a crane is used to lift the lugs 108 on the leveling frame 10, so that the leveling frame 10 can be lifted quickly and stably. Of course, in other embodiments, a tugboat can also be used to tow the leveling frame 10 to the dock area.

[0031] As a preferred embodiment, the end of the transverse tube 101 is detachably connected to the end of the longitudinal tube 102. The transverse tube 101 and the longitudinal tube 102 are assembled in a detachable manner, which facilitates disassembly and transfer.

[0032] As a preferred embodiment, the transverse tube 101 and the longitudinal tube 102 are both formed by splicing a plurality of circular tubes. The transverse tube 101 and the longitudinal tube 102 with a circular tube structure have a simple structure and are easy to process.

[0033] As a preferred embodiment, the four corners of the bottom of the leveling frame 10 are respectively provided with telescopic legs 20, and the telescopic legs 20 are equipped with telescopic hydraulic cylinders. The telescopic legs 20 can support the leveling frame 10 on the underwater bed, and the telescopic hydraulic cylinders can control the extension and retraction of the telescopic legs 20 to adjust the elevation of the leveling frame 10 with good control accuracy.

[0034] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limiting the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the present invention.
