Description

Technical Field

[0001] The utility model relates to the technical field of underwater rubble bed ramming equipment, in particular to an underwater rubble bed ramming protection device. Background Art

[0002] Underwater bed ramming is of great significance. By improving the bearing capacity of the foundation, reducing settlement and deformation, enhancing soil density, and improving soil properties, it ensures the stability and safety of underwater structures. This process can effectively prevent foundation instability, reduce settlement differences, improve construction quality, and ensure the long-term stability and bearing capacity of structures in the underwater environment.

[0003] The utility model patent with the publication number CN216238351U discloses an underwater rubble bed ramming noise reduction device, which includes a bracket and multiple high-pressure air pipes fixed on the bracket. Each air pipe is provided with an air inlet for introducing high-pressure air, and a plurality of exhaust holes are evenly arranged along the axial direction. In water, the bubbles discharged from these exhaust holes will form an air wall around the bracket, thereby effectively reducing the impact of noise during bed ramming on surrounding organisms.

[0004] Although this patent can effectively block the noise during the construction process, there will still be some splashing of broken stones during the ramming construction process, and the splashing broken stones will also damage the surrounding environment and organisms. Moreover, during the descent of the device, there will be some fluctuations in the ocean. Therefore, the utility model proposes an underwater rubble bed ramming protection device.

A plurality of evenly distributed ground inserting parts are fixedly installed at the bottom end of the protection cylinder. A plurality of air outlet holes are arranged inside the protection cylinder. One end of an air delivery pipe is fixedly installed near the bottom end, and one end of the air delivery pipe is communicated with the plurality of air outlet holes. The plurality of air outlet holes eject high-pressure gas to achieve the sound insulation effect.

[0007] Further, the gas transmission component further includes a second winding roller, which is rotatably installed on the bracket. The second winding roller is connected to the gas transmission pipe. The other end of the gas transmission pipe is fixedly installed with a high-pressure air pump, and the high-pressure air pump is fixedly installed on the bracket. A second rotating shaft penetrates through the second winding roller. At both ends of the second rotating shaft, a first bevel gear is fixedly installed.

A sliding track is slidably installed on the connecting block, and the sliding track is fixedly connected to the bracket. The lifting unit further includes two groups of symmetrically distributed winding assemblies. By sliding the connecting block on the sliding track, it is ensured that after the protection unit sinks, it will not deviate from the bed ramming device.

The winding assembly further includes a first winding roller, which is rotatably installed on the bracket. A rope is wound around the first winding roller. One end of the rope is fixedly installed on the first winding roller, and the other end of the rope is connected to the connecting piece.

The second bevel gear meshes with the first bevel gear. The first bevel gear drives the second bevel gear to rotate, and the second bevel gear drives the first winding roller to rotate through the first rotating shaft, so that the protection cylinder can be conveniently recovered and reset after the construction is completed.

[0012] Further, the inside of the sliding track is hollow, and the hollow sliding track can be extended through an extension rod, so that the protection unit can reach a deeper bed.
