（発明の技術分野）
本発明は、多数条の海底ケーブルを一括して布設船から
海底に布設する海底ケーブルの多条布設方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a multi-strand submarine cable laying method for laying a large number of submarine cables at once from a laying ship to the seabed.
（発明の技術的背景とその問題点）
多数条の海底ケーブルを海底布設する際、従来は、布設
船上で各海底ケーブルを一括してテープあるいは紐等に
より逐次バインドしながら海中に繰り込むようにしてい
た。しかしながら、このよあるいは埋設機内でテープ等
が外れ易く、外れた場合には各テーブルが離ればなれに
なり、ケーブルの布設位置が管理できなくなることがあ
った。(Technical background of the invention and its problems) When laying a large number of submarine cables on the seabed, conventionally, each submarine cable was sequentially bound with tape or strings on board the laying ship and then fed into the sea. . However, the tape or the like tends to come off in the embedding machine, and when it comes off, the tables become separated, making it impossible to manage the cable laying position.
またテープ等をバインドするために多大な時間と労力を
要し、工事費用も高くなるという欠点かあった。Another drawback was that it required a great deal of time and effort to bind the tapes, etc., and the construction costs were also high.

付けた状態で海底に布設するものである。(Summary of the Invention) That is, the method of the present invention is a self-defense method for laying a large number of cables on the seabed at once on a laying ship, and a flexible pipe with a lengthwise split. This involves encasing the pipes all at once and bringing them into the sea one by one, and installing them on the seabed with flexible pipes attached.

A drum 3 containing three submarine cables 2 each to be laid on the seabed and a drum 5 containing one flexible vibrator 4 are installed on the top. The flexible vibrator 4 is made of plastic such as polyvinyl chloride and has a split 4a in the length direction, and by opening the split 4a, three submarine cables 2 can be accommodated at once.

可撓バイブ４は海底ケーブル２の全長に亘って包覆する
必要がなく、断続的に包覆するものであってもよい。The flexible vibrator 4 does not need to cover the entire length of the submarine cable 2, and may cover the submarine cable 2 intermittently.

る。(Effects of the Invention) As described above, according to the method for laying multiple submarine cables according to the present invention, multiple cables can be laid like a single cable, so the installation work can be carried out efficiently and in a short time. obtain. In addition, since multiple submarine cables are encased in a flexible vibrator, each table will not be separated while submerged in the sea or passing through the burial machine, and each cable can be laid easily. Convenient for managing location.
