AI Technical Summary

Technical Problem

Traditional submarine cable protection technology has problems such as difficult construction, high maintenance costs, large environmental impact and poor adaptability, and it is difficult to effectively resist erosion in complex marine environments.

Method used

Using a sacrificial pile structure, by laying pile bodies around the submarine cable, the anti-shrinking ability of the pile bodies disperses the water flow energy, thereby reducing direct erosion of the cable. The structure includes a sacrificial pile body, a protective cured pile structure and a locking mechanism, which can be quickly assembled and disassembled to adapt to different sea conditions.

Benefits of technology

It effectively improves the anti-shocking capacity of submarine cables, extends the service life, reduces construction and maintenance costs, and has a small impact on the marine environment.

Abstract

The invention belongs to the technical field of submarine cable scour prevention, and provides a sacrifice pile structure for submarine cable scour protection, which comprises a sacrifice pile body, the periphery of the bottom end of the sacrifice pile body is uniformly connected with a plurality of fixing blocks, each fixing block is provided with a through hole in a penetrating manner, and the periphery of the sacrifice pile body is further sleeved with a protection solidification pile structure. The protection solidification pile structure comprises a first scouring protection outer cover and a second scouring protection outer cover, the first strip-shaped base and the second strip-shaped base are each provided with two locking mechanisms, and an inner cavity of the first scouring protection outer cover is provided with a mounting component. The sacrifice pile structure for submarine cable scour protection can effectively resist the tidal current effect from the sea condition environment, the situation that soil around the submarine cable body is eroded and scoured is avoided, the scour prevention capacity of the submarine cable is improved, the stability of a seabed around the submarine cable is enhanced, and the service life of the submarine cable is prolonged. Therefore, the use safety of the submarine cable is improved.
