Problems solved by technology
[0002] At present, for ocean communications for military and communication purposes, it is necessary to bury cables on the seabed to achieve transoceanic transmission; at the same time, for double insurance or other functional purposes, it is often necessary to bury two submarine cables at the same time; conventional burying methods The cable-laying ship needs to carry out two operations, and the two submarine cables are laid separately in two times. The two-time operation method greatly increases the construction cost (there is a cost of two operations), and secondly, it increases the difficulty of construction. ——Due to the relationship between positioning accuracy, there must be a displacement deviation during the two laying processes, resulting in poor laying effect and affecting the performance of the submarine cable; for this reason, a new double-cable laying process in the same ditch is urgently needed to solve the above problems question

Embodiment Construction
[0025] see Figure 1~4 , the present invention relates to a double-cable co-ditch embedding process, said double-cable co-ditch embedding process includes the following steps:
[0026] Step 1, place the initial anchor: connect the initial anchor with the lead cable, the construction ship will berth on the sea surface of the predetermined construction site through the satellite positioning device, the lead cable will pass through the buried plow, and then the construction ship will use the cable laying machine to place the initial anchor Lowered vertically to the seabed;
[0027] Step 2, moving forward: the construction ship moves forward for 100 meters along the embedding direction, and releases the lead cable through the cable laying machine while maintaining tension during the forward process;
[0028] Step 3, lowering the buried plow: the construction ship lowers the buried plow through the traction cable, so that the buried plow sinks to the seabed under the guidance of t...

The invention relates to a dual-cable one-ditch laying technology. The dual-cable one-ditch laying technology comprises the following steps of 1, placing an initial anchor; 2, moving forwards; 3, putting down a burial plough; 4, performing adjusting, wherein cables are collected and reamed; 5, laying one cable; 6, laying dual cables. According to the dual-cable one-ditch laying technology, one workboat can lay two submarine cables at the same time.
Description
technical field [0001] The invention relates to a submarine cable embedding process, in particular to a process for burying two submarine cables together in a ditch, and belongs to the technical field of marine engineering. Background technique [0002] At present, for ocean communications for military and communication purposes, it is necessary to bury cables on the seabed to achieve transoceanic transmission; at the same time, for double insurance or other functional purposes, it is often necessary to bury two submarine cables at the same time; conventional burying methods The cable-laying ship needs to carry out two operations, and the two submarine cables are laid separately in two times. The two-time operation method greatly increases the construction cost (there is a cost of two operations), and secondly, it increases the difficulty of construction. ——Due to the relationship between positioning accuracy, there must be a displacement deviation during the two laying proc...
