Embodiment 1

[0053] Such as figure 1 , figure 2 and image 3 As shown, in the underwater support device of the present invention, the lower end of the support frame body 1 is connected to the underwater foundation 2, and the near-end edge of the protective sand bag 3 is provided with a connecting belt, and the connecting belt is provided with a plurality of through holes, and the protective sand bag The bag 3 is bolted to the side of the underwater foundation 2 through the through holes on the connecting strap. The bag body of the protective sand bag 3 is folded along the direction from the far end to the proximal end, and the folded part faces upward. The movable buckle assembly 4 is arranged around the protective sand bag 3 , and both ends of the movable buckle assembly 4 are bound on the surface of the underwater foundation 2 . The bag body of protective sand bag 3 proximal ends is provided with filling port, and support frame body 1 is provided with sand-filling pipe 5, and one end...

Embodiment 2

[0057] The underwater supporting device of the present invention is characterized in that it is basically consistent with Embodiment 1, the difference is that:

[0058] (1) The material strength of the movable buckle assembly 4 is designed to break after exceeding the rated tensile force F, and the rated tensile force F is greater than the weight of the protective sand bag 3 and less than the protective sand bag filled with 1 / 8 of the bag body 3 gravity;

[0059] Or if it belongs to the idea of ​​this plan, incomplete cutting is performed on a part of the movable buckle assembly 4, so that the strength of the part is weakened, and the part breaks after exceeding the above-mentioned rated tensile force F.

[0060] After the construction and installation are completed, when sand is filled into the protective sand bag 3 through the sand filling pipe 5, due to the extrusion effect of the mud and sand and the action of gravity, after the external force received by the movable buckl...

Embodiment 3

[0063] Such as Figure 4 As shown, in the underwater supporting device of the present invention, the lower end of the supporting frame body 1 is connected to the underwater foundation 2 , and the surface of the underwater foundation 2 is provided with a first pull ring 21 . The edge of the proximal end of the protective sandbag 3 is fixedly tied to the first pull ring 21 . The bag body of the protective sand bag 3 is rolled up along the direction from the far end to the proximal end, and the rolled up part faces upward. One end of the tie rope 41 is connected to the first pull ring 21 and the other end is connected to the second pull ring 42 , the tie rope 41 is arranged around the protective sand bag 3 , and the second pull ring 42 overlaps with the first pull ring 21 . The pull rope 43 passes through the inner circles of the first pull ring 21 and the second pull ring 42 at the same time and is tightened, so that the tie rope 41 is tightened. The two ends of the stay rope ...

Abstract

The invention discloses an underwater support device, offshore equipment and an installation method for the underwater support device, and aims to provide an underwater support device that is convenient for construction and does not require underwater operations. The key points of the technical scheme are: The surface of the foundation is fixed with a protective sand bag in a folded state, and a movable buckle assembly is arranged around the protective sand bag. After the construction of the underwater foundation and the support frame body is completed, the movable buckle assembly is untied, and the protective sand bag is filled with sand, thereby The reinforcement and protection of the underwater foundation are realized, and the operation steps are simple, avoiding the operations of laying sand bags and underwater operations by the hoisting ship, and saving construction costs.

Description

technical field [0001] The invention relates to the technical field of offshore equipment, in particular to an underwater support device, an offshore equipment and an installation method for the underwater support device. Background technique [0002] With the continuous development of offshore equipment technology, the requirements for the construction and installation of equipment support mechanisms are also getting higher and higher. The underwater support part of the existing offshore equipment is usually designed by building a support frame above the underwater foundation such as a pile foundation or a negative pressure cylinder foundation. However, for these underwater supporting parts, on the one hand, the water flow will continuously scour the seabed around the underwater foundation, causing uneven settlement, tilting or loosening of the underwater foundation; Due to the moment action in all directions, it is difficult to ensure the stability of the simple underwate...
