Description

Submarine cable embedding equipment {SUBMARINE CABLE BURIAL MACHINE}

The present invention relates to a cable embedding equipment, and more particularly to a subsea cable embedding equipment that is easy to install the bottom of the cable by inducing buried at the same time when the cable buried in the seabed.

In general, underwater excavation and burial equipment is used to build a variety of structures, such as long-distance oil pipelines, water pipes, such as communication or power lines on land and islands, or through the sea, the underwater excavation And the open cut method is mainly used as a method for embedding various structures using the buried equipment, the open cut method is to excavate the underwater ground of the excavation position with an underwater excavator (Grab, etc.) to the excavation cross section As a method of laying and refilling the structure, this open cut method was pointed out as a disadvantage in that the construction quality is long and the construction time is long, and the construction cost is high.

On the other hand, the construction of the underwater drilling and buried equipment of the buried method is equipped with a self-generator and other control equipment, and submersible and submersible submersible pump equipped with an air compressor, a hydraulic cylinder, etc. It is largely composed of an excavator equipped with a hydraulic injection nozzle connected to excavate the seabed surface destroyed by the plow.

Underwater excavation and buried equipment of the conventional buried method configured as described above excavates the first bottom surface with a plow provided in the submersible, and excavated the bottom surface excavated with a strong injection force through a hydraulic spray nozzle connected to the underwater pump, Various structures will be buried in place.

Such underwater drilling and embedding equipment should be placed on the excavation section after the completion of the excavation process from the initial construction point to the end point, and at the end of the excavation, part of the excavation will be partially filled due to the flow rate in the previous excavation section. Therefore, there is a problem in that the structure can not be accurately seated in the desired position.

In addition, in the process of dropping the structure at the end of the excavation, it is not possible to settle the exact position of the excavation section due to the flow rate, so it is required to move the underwater structure by the divers, resulting in excessive labor and time costs. There is a problem that is a very troublesome and a lot of risk of moving the above operation.

In addition, in the excavation method, after the excavation, as the structure is installed, part of the excavation becomes partially filled due to the flow rate in the excavated excavation cross section, and thus, the excavation method cannot be accurately seated at a desired position, and a wide excavation cross section is provided. Due to this, it is impossible to completely backfill due to the natural flow rate, so a separate artificial backfill process is required, and there is an uneconomical problem in that the cost of the artificial backfill process is excessive.

In addition, it is mainly applicable to soft sea bed, and the ground such as soft rock, gravel mixed sand, hard rock, etc. cannot be excavated, and the sea bottom was excavated using underwater blasting work or diver. However, the above method is very troublesome to undersea ground excavation work, contains a lot of risks, there is a problem that excessive cost.
