本発明は海底ステーション用ブロック（海底に長期的な
探査、発信等の基地となるステーションを構成するため
のブロック）を海底の定点に設置する方法に関する。[Detailed description of the invention] (Technical field to which the invention pertains) The present invention is directed to installing a block for an undersea station (a block for configuring a station on the seabed as a base for long-term exploration, transmission, etc.) at a fixed point on the seabed. Regarding the method.
（発明の課題とその特徴点）

ていない。(Problem to be solved by the invention and its characteristics) Various instruments have been introduced and installed on the ocean floor to measure physical and chemical quantities on the ocean floor, but it is still difficult to conduct long-term observations at fixed points. It is not yet possible to do so.
本発明は、前述の実情に鑑みてなされた技術開発の一環
をなすものであって、海底ステーション用ブロック（以

の特徴は特許請求の範囲に記載したとおりである。The present invention is a part of technological development made in view of the above-mentioned circumstances, and aims to provide a method for accurately installing a block for a submarine station (hereinafter simply referred to as a block) at a predetermined point on the seabed. and its structural features are as described in the claims.
本発明における海底設置の３つのトランスポンダの絶対

位置を知る方法、を用いればよい。In the present invention, the absolute positions of the three transponders installed on the seabed can be measured and detected using conventionally known methods. A method may be used in which the relative position of each transponder is detected based on data obtained from communication using acoustic pulse signals between each transponder and the ship, and the absolute position of each transponder is determined from these.

が好ましい。In the invention of claim <2), the block is placed a certain distance li from the seabed! The reason why the lobe is removed from the block after it has been lowered to a distant position and the block is then allowed to fall freely is that if the lobe is removed from the block after the block reaches the seabed, it will reduce the rocking of the work boat. This is because there is a risk that the block may be dragged on the ocean floor due to movement, etc., and even if the lobe detachment device is activated, it is difficult to confirm that the lobe has been detached.Currently, the lobe detachment position is not far from the ocean floor. It is thought that a distance of about 2 to 3 meters above is appropriate, and it is preferable to detect this distance using a pinger (a range finder that uses sound wave reflection) attached to the block.

。Then, remove the row 15 from the block 6 at an appropriate stage,
As mentioned above, it is preferable to remove the row 15 from the block 6 when the block 6 has been lowered to a certain distance from the seabed, and then allow the block 6 to freely descend.
To explain this case using FIG. 3, transponder A
, B, and C while detecting the position of the work boat 3, navigate the work boat 3 to a predetermined position [state 1 of (a), after locating the lowering position of block 6] , the block 6 is suspended by lobes 5,5'' and lowered into the sea, and during the descent, the position of the block 6 is detected and confirmed, and the necessary position correction is made. The distance from the block 6 to the seabed is continuously measured by the pinger attached to the system. When the block 6 has descended to a predetermined distance from the seabed in state 1 of (υ), the descent of the block 6 is stopped [ Case 91 of (c), the operation signal is sent from the work boat 3, the detachment device 8 attached to the tip of the lobe 5 is remotely operated, the lobe 5° is removed from the block 6, and the block 6 is brought to the installation point S by free descent. Let it touch the bottom [state 1 of (d)] In this case, a tension gauge is provided on the row 15, and the row 1
By detecting a change in the tension of the block 6, it can be confirmed that the lobe 5° is removed from the block 6.
