る。Generally, when a cable is laid on the ocean floor, etc., and the location is formed of uneven hard rock, etc., the cable is laid through two or more convex parts, for example, in a hole-shaped part.
This may result in a so-called 6-bridge shape. In this case, there is a risk that the contact portion between the cable and the rock etc. will slide over a long period of time due to the influence of tidal currents and the like, ultimately resulting in an accident such as a breakage of the cable. If this is not possible, check to see if the cable has completely landed on the seabed after laying it, and if
If there is a save lip, it must be removed.

査部材２の水底の姿勢を検出する手段を形成している。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an apparatus for investigating the landing state of a cable installed on the bottom of water according to the present invention will be described below with reference to FIGS. 1 and 2. 1st
The figure is an explanatory diagram of the landing state inspection situation, and Figure 2 is the ll of Figure 1.
-Tll is a section view as seen from the arrow. , In the figure, ■ is a cable laid on the seabed, 2 is a rotating survey member, and cable 1
When the cable 1 is loosely fitted and pushed through, has an elliptical cross section, and is installed so that the axial direction of the cable 1 and the long axis of the ellipse are perpendicular to each other, and cannot contact the seabed surface 5 such as a recessed position on the bottom of the water. The long axis of the shape is located in the vertical direction. Reference numeral 3 denotes a non-rotating member, which is continuous with the rotating investigating member 2 and has a pulling wire rope 4 attached thereto for pulling the rotating investigating member 2. Reference numeral 8 denotes a landing posture detection device, which includes an arc-shaped sealed hollow portion 9 formed at the longitudinal end of the rotation investigation member 2 with the central axis of the ellipse on the inner side of the radius, and a plurality of devices formed within the arc-shaped sealed hollow portion 9. It consists of a contact point 6 and a liquid conductive member made of mercury 7 filled inside so as to occupy a part of the space. The landing posture detection device 8 is a landing posture detection device 8.
At the position of mercury 7 in the ship, the connection of contact 6 is changed to electrical on-off, and the information obtained by this is sent out as an electrical signal to the ship on the water (sea) by wire.
A means for detecting the attitude of the rotating investigation member 2 on the bottom of the water is formed by a known transmission device (not shown) that transmits sound waves with different wavelengths from each contact point 6 and detects them on board the ship. .

、回転調査部材２は二つの割りに形成してもよい。The rotary investigation member 2 is formed so that when it is located at the recess position 10 portion of the seabed surface 5 (see FIG. 3), the landing attitude detection device 8 side is always located at the lower end side. To avoid this, the hole 11 through which the cable 1 is loosely inserted is provided eccentrically, not at the center of the elliptical cross section, so that when floating in water, the same position is always the lowest position. In addition, a cavity is provided or a weight is attached to one of the major diameter sides of the elliptical cross section, but by being composed of composites with different specific gravity, the same direction is always the bottom side when floating in water. Good too. The rotation investigation member 2 may be formed in two pieces.
上記の回転調査部材２の穴１１にケーブル１を挿通した
状態でケーブル１を海底面５に布設する。The cable 1 is inserted into the hole 11 of the rotating investigation member 2 and laid on the seabed surface 5.

- sliding the rotating investigation member 2 via the part 4 along the cable 1 over the seabed surface 5 in the direction of arrow A; If the cable 1 is in the concave position 1o, for example, as shown in FIG. The situation is detected, a signal thereof is transmitted to a ship on the sea, and the landing attitude of the rotating investigation member 20 is indirectly detected.
