Description

Technical Field

[0001] This utility model relates to the field of pontoon technology for submerged barges, specifically to a pontoon structure and a submerged barge suitable for the structure. Background Technology

[0002] The immersed barge is mainly used for the transportation and installation of immersed tubes in coastal and inland river underwater tunnel projects. It has the functions of connecting immersed tubes out of the dock and floating immersed tubes to the construction water area for positioning and installation. During operation, multiple pontoons are assembled to support the immersed barge. The pontoons and the immersed barge work together to position and install a section of immersed tube.

[0003] Currently, the assembly and splicing of multiple pontoons is usually done by fixing them with bolts to secure the top and bottom of two pontoons. Fixing the bottom of the pontoons is not only troublesome, but also prone to corrosion underwater, which is not conducive to the subsequent disassembly and assembly of the pontoons. Furthermore, the close fit between two pontoons makes them prone to collision damage. There is an urgent need to design a pontoon structure and a suitable submersible barge to solve the above problems. Utility Model Content

[0013] In the above technical solution, the present invention provides a floating box structure and a submersible barge suitable for this structure, which have the following advantages:

[0014] The hooks and hook seats allow one of the two tanks to be lowered during assembly, enabling the hooks to engage from the bottom. This facilitates the underwater connection and assembly of the two tanks, reducing the risk of corrosion on the underwater threaded connections. The bolt boxes, once the bottoms of the two tanks are fixed, align with each other, allowing the fixing bolts to pass through the bolt holes and secure the tops of the two tanks. The rubber fenders on the sides of the tanks provide cushioning when they are brought close together for assembly, reducing the risk of collision damage. After assembly, the rubber fenders remain within the grooves and do not interfere with the assembly process. Attached Figure Description

Support blocks are provided between the four sides of the support rod 15 and the support plates 16. The top and bottom of the inner wall of the housing 1 are fixedly connected to two support plates 16 respectively. The support rods 15 allow them to be installed inside the housing 1, providing support for the interior of the housing 1 and preventing collapse.

[0027] Reference Figure 2 In this embodiment, a manhole 17 is provided on the top of the box body 1, and a cover 18 is rotatably fitted on the top of the box body 1, with the cover 18 located above the manhole 17. The cover 18 can cover and close the manhole 17, and after the cover 18 is opened, personnel can enter the box body 1 through the manhole 17 to inspect the interior.

[0028] Reference Figure 3 In this embodiment, a sealing plate 19 is rotatably fitted to the top of the bolt box 8. A snap-fit ​​assembly is provided between the two corresponding sealing plates 19. The snap-fit ​​assembly includes a slot 20 formed at one end of one sealing plate 19 and a snap-fit ​​block 21 formed at one end of the other sealing plate 19.

After the two sealing plates 19 are closed, the snap-fit ​​block 21 can enter the slot 20 to fix the two sealing plates 19.

[0029] Reference Figure 4 In this embodiment, the hook 11 is L-shaped and the hook base 12 is J-shaped. One end of the hook 11 is provided with a bevel 22, and one end of the hook base 12 is provided with a trapezoidal block 23. Through the bevel 22, after the hook 11 enters the hook base 12 and engages, the bevel 22 and the trapezoidal block 23 are aligned. After the top of the box 1 is fixed, the hook 11 is completely fixed in the hook base 12. After the top of the box 1 is contacted and fixed, the bevel 22 can move along the trapezoidal block 23, allowing the hook 11 to move out of the hook base 12.

[0030] A submersible barge, applicable to any of the above-mentioned floating box structures, specifically includes: a floating island module 24 and a crossbeam 25. The floating island module 24 is disposed on the top of multiple boxes 1, the crossbeam 25 is disposed between two floating box structures, a lifting mechanism is provided on the crossbeam 25, a positioning block 26 is installed on the top of the box 1, the top of the positioning block 26 is provided with a positioning groove, and positioning rods 27 are installed on both sides of both ends of the crossbeam 25, the positioning rods 27 corresponding to the positioning grooves.

[0031] The crossbeam 25 is composed of multiple sealed boxes, which can be spliced ​​together to the required degree. The crossbeam 25, consisting of multiple sealed boxes, can float and move in the water tank.

[0032] Working principle: In use, multiple containers 1 are assembled and spliced ​​together to form a floating container structure. Two containers 1 are spliced ​​together, and jacks and supports are installed on each of the two containers 1. The jacks support the supports, at which point one container 1 moves downward, causing the hook 11 and hook seat 12 to misalign. Then, a hand chain hoist is used to pull the two containers 1 closer together, so that the rubber fenders 7 on the sides of the containers 1 contact each other for cushioning. After the two containers 1 are in contact, the jacks supporting the supports are removed, and the two bolt boxes 8 are aligned. At this time, the hook 11 will enter into the hook seat 12 for locking and fixing, securing the bottom of the two containers 1. Then, fixing bolts 10 are used to pass through the two bolt boxes 8. The corresponding bolt holes 9 inside the bolt box 8 are used for fixing, and the tops of the two boxes 1 are fixed to complete the splicing and assembly between the boxes 1. Repeat the above steps to assemble multiple boxes 1 into a floating box structure. Then, the floating island module 24 can be installed on the floating box mechanism so that the sample can work on the floating island module 24. When installing the crossbeam 25 between the two floating box structures, the two floating box structures are lowered. The crossbeam 25 is pulled between the two floating box structures using a cable on the floating island module 24 so that the positioning rod 27 corresponds to the positioning block 26. Then the floating box structure floats up, so that the positioning rod 27 enters the positioning groove of the positioning block 26 to position the crossbeam 25. Subsequently, the fixing mechanism is used to connect and fix the crossbeam 25 and the floating box structure.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
