Therefore, a construction process capable of solving the above problems is desired.

a pipe and cable construction process comprises the following steps:
firstly, a vertical pipe cable laying ship approaches to a junction of a deep water area and a shallow water area, and a connecting ship approaches to the vertical pipe cable laying ship;
secondly, the vertical pipe cable laying ship transfers the pipe cable inverted part wound on the vertical winding disc into a cable bin on the connecting ship, and the length of the pipe cable wound in the cable bin is not less than the distance between the vertical pipe cable laying and the electric centralized control central station;
thirdly, the barge sails to the electric centralized control central station for laying cables, and simultaneously the vertical pipe cable laying ship synchronously carries out cable laying operation to the booster station/converter station;
the specific process of sailing and cable laying of the barge to the electric centralized control central station is as follows:
the connecting ship firstly enters a tidal stream area of a shallow water area to be cabled;
and after entering a landing section of a shallow water area, dragging the remaining pipe cable on the barge into an on-shore power centralized control central station by using dragging equipment after the remaining pipe cable is refunded, and tying a floating ball on the pipe cable positioned in the landing section.
Compared with the prior art, the invention has the beneficial effects that:
the invention can conveniently and rapidly realize the transfer of the pipe cable by storing the pipe cable in a vertical type winding manner, has no torsion problem, and is efficient and safe; meanwhile, the laying effect of the pipe cable can be synchronously carried out after the pipe cable is transferred, so that the efficiency is greatly improved, and the construction cost is effectively reduced.
