めった。However, when such conventional submarine cables are laid at the same time, 11! Because it is difficult to precisely control the ship's speed using the crotch method, excessive tension remained in the buried submarine cable 3), and there was a risk that the cable 3 would become trapped under the buried equipment aSO and be damaged. In addition, the rolled cable 3 that can withstand a huge laying tension is required to have a tensile strength of several tons or more, and there is often a drawback that cables with a small breaking tension cannot be laid and buried at the same time.

At the center of the lower surface of the fruit stand 23, a trench excavator 6 such as tJl for digging a cable 8 for burying the cable on the seabed surface 7 is installed downward, and at the center of the upper surface, a trench excavator 6 for excavating a cable 8 for burying the cable is installed at the center of the upper surface.

is installed. The submarine cable 3 was twisted 91 times per turn and wound into a record groove shape (spiral shape) as shown in FIG. 4(A) or a high photocoid shape as shown in FIG. 4(b). The cable is housed in the cable storage container 24 in a state of
The cable is led into a groove 8 at the rear lower part of the trench excavator 6 via a cable lead-out hole 21 formed through the trench excavator 6. When the submarine cable 3 is wound in a no-ibotrochoid shape, compared to when it is wound in a record groove shape,
゛Contact +k between the wires can be reduced, and as a result, the cable 3 can be prevented from jumping up when being pulled out, and can be pulled out smoothly.

A rotatable presser wheel 2B is disposed at the lower end opening of the cable outlet hole 2T, and this presses the submarine cable 3 against the bottom of the groove 8.

の布設同時埋設を可能にする。In such a configuration, when the power boat 20 tows the burial device 21 carrying the submarine cable 3 along the seabed T, the S excavator 6 excavates a trench 8 in the seabed 7. The submarine cable 3 in the cable containment vessel 24 is moved upward as the burial device 21 moves forward and is naturally pulled out from the cable outlet 21, and the M1 wire of one winding is returned and the # 8 without any residual twist. Therefore, it is possible to feed out a long cable. In addition, in the conventional laying and burying method shown in Figure 6, a tension equivalent to the sum of the amount of underwater In contrast, in the present invention, the cable is buried [2]
Since the effect of the tension can be reduced to almost nothing by letting it out from 1, it is possible to simultaneously lay and bury a small-diameter Sawasoko optical cable with low breaking tension.

残留する可能性が高い。Here, when the dish installation M21 is towed by a ship as shown in FIG. It shows the so-called stick-slip phenomenon in which forward and stop t-repetition occurs. In order to prevent the submarine cable 3, which is laid and buried at the same time, from breaking, it is necessary to control the cable payout length of the burying equipment W21 to be equal to the amount of movement of the burying equipment. In the conventional method shown in FIG. Fine control of the cable payout amount is impossible because the distance between the burial device 5 and the onboard cable engine 4 is too far, and there is a high possibility that tension will remain in the buried cable.

。- 10,000, in the method for simultaneously laying and burying the cable according to the present invention, the burying device 2
Since the cable 3 mounted on the burying device 21 is naturally pulled out according to the amount of movement of the cable 3, even a submarine optical cable with a breaking tension of about 100 lines can be buried without breakage or residual tension. In addition, a groove width of 1 m is sufficient for a small submarine optical cable engine with an outer diameter of several millimeters, so excavation resistance is small. Therefore, there is an advantage in that W can be buried to a depth of about 1 m using a small burying device that is slightly smaller than conventional burying devices and has lengths and widths of about 3 m. Furthermore, it is not necessary to use a laying ship to tow the buried equipment w121, and a small general-purpose vessel such as a work boat can be used.

Note that even when other burying methods such as jet burying are used, the cable storage and feeding means are the same as described above.

とが可能になる。As explained above, according to the submarine cable laying and simultaneous burying method and its device according to the present invention, the cable containment vessel for storing the submarine cable is directly installed on the pedestal that moves on the seabed surface, so that the underwater weight acting on the cable is reduced. This enables the installation and burial of small-diameter submarine optical cables that are virtually unaffected by tension caused by tidal current resistance and have low breaking tension and lateral pressure resistance. 11 Put the submarine cable in the form of a record cast or hypotocolloid (twisting 91 times per turn) and wind it up.
Since the cable is lifted up when it is unrolled, one twist per roll is unraveled without the need for power or control equipment, and if any twist remains in the cable, it can be laid and buried at the same time smoothly. This makes it possible to economically construct highly reliable submarine A-roads.
