【発明の詳細な説明】
「第１〜３図」の埋設機は、本発明の実施に使
用するものであるが、従来のものも、ほぼ同じ構
成である。まず、それについて説明する。DETAILED DESCRIPTION OF THE INVENTION The embedding machines shown in "Figs. 1 to 3" are used to carry out the present invention, but the conventional ones also have almost the same configuration. First, let me explain about it.
１０はそり、１２はフレームで、たとえば、上
下が空いている前後に細長い四角の箱形である。
１４はアームで、これによつてそり１０、フレー
ム１２間を連結する。 10 is a sled, and 12 is a frame, for example, in the shape of a rectangular elongated box with open space at the top and bottom.
An arm 14 connects the sled 10 and the frame 12.
１６は掘削体である。たとえば直角三角形で
（第２図）、その前部１６０を軸１８（フレーム１
２の前端に横渡しされている）によつて、揺動自
在に支持される。 16 is an excavation body. For example, a right triangle (Fig. 2), whose front part 160 is connected to the axis 18 (frame 1
(which extends across the front end of 2), it is swingably supported.
そり１０は海底面２０に接し、引きワイヤ２２
で引つぱられる。掘削体１６の前方傾斜部１６２
からは、水ジエツト２４が、噴出し、海底を掘削
してゆく。 The sled 10 is in contact with the seabed surface 20 and the pull wire 22
It is pulled by. Front inclined portion 162 of excavation body 16
From there, a water jet 24 spews out and excavates the seabed.
また、海底長尺体２６は、掘削体１６の前部１
６０から入り、後部１６４の下部から出て、掘削
された溝内に埋設される。 Further, the seabed elongated body 26 includes a front portion 1 of the excavation body 16.
60, exits from the lower part of the rear part 164, and is buried in an excavated trench.
以上は公知の埋設機（たとえば特公昭54−
22014号公報など参照）。 The above is a well-known burying machine (for example,
(See Publication No. 22014, etc.)
海底長尺体２６を埋設してゆくとき、海底の土
砂の硬さが変わつたり、引張り速度が変化した
り、あるいは、水ジエツト２４の圧や量が変わつ
たりすると、掘削体１６の後部１６４が「第４
図」のように浮上したり、あるいは下降したりす
る。そのため、長尺体２６を一定の深さに埋設す
ることができなくなる。 When burying the long seabed body 26, if the hardness of the seabed soil changes, the pulling speed changes, or the pressure or amount of the water jet 24 changes, the rear part of the excavated body 16 may change. 164 is “4th
It rises or descends as shown in the figure. Therefore, it becomes impossible to bury the elongated body 26 at a constant depth.
本発明は、掘削体１６の後部１６４に加わる重
量を調節して、常に長尺体２６を一定の深さに埋
設できるようにしたものである。 The present invention allows the elongated body 26 to be buried at a constant depth by adjusting the weight applied to the rear part 164 of the excavation body 16.
発明の構成
２８は重りである。掘削体１６の上面に、前後
に移動できるように取り付けられる。重り２８を
移動させるために、たとえば、それにネジ棒３０
を対偶させ、ネジ棒３０をモータ３２で回転させ
る。Structure of the invention 28 is a weight. It is attached to the upper surface of the excavation body 16 so as to be movable back and forth. To move the weight 28, for example, a threaded rod 30 is attached to it.
are paired together, and the threaded rod 30 is rotated by a motor 32.
３４はストツパで、たとえば、掘削体１６の後
部１６４に取り付けた１本の横棒である。それ
が、「第２、第３図」のようにフレーム１２の上
面に当たると、掘削体１６はそれ以上回動（第２
図で時計方向）できない。これにより埋設深さ
が、一定値以上にならないようにする。 A stopper 34 is, for example, a horizontal bar attached to the rear part 164 of the excavating body 16. When it hits the upper surface of the frame 12 as shown in "Figures 2 and 3", the excavation body 16 rotates further (second
(clockwise in the diagram) cannot be done. This prevents the burial depth from exceeding a certain value.
調節の方法
長尺体２６の埋設中における、掘削体１６の後
部１６４の下降および浮上の状況は、公知の埋設
深度計３６（たとえば特公昭52−47558号公報な
ど参照）やTVカメラ（図示省略）などによつ
て、船上から監視する。Adjustment method During the burying of the elongated body 26, the lowering and rising conditions of the rear part 164 of the excavated body 16 can be monitored using a known burial depth gauge 36 (for example, see Japanese Patent Publication No. 52-47558) or a TV camera (not shown). ) etc. to monitor from the ship.
そして、たとえば後部１６４が上がり過ぎた
ら、重り２８を後に移動させる。すると後部１６
４が重くなつて下降する。下がり過ぎる時は、そ
の反対にする。これらの操作も、船上で行なう。 Then, for example, if the rear portion 164 rises too much, the weight 28 is moved backward. Then the rear 16
4 becomes heavier and descends. If it goes too low, do the opposite. These operations are also performed on board.
発明の効果
以上の操作を繰返すことにより、掘削体１６の
後部１６４が所定の深度（海底面に対する）を保
持するようになるので長尺体２６の埋設深さを一
定にすることができる。Effects of the Invention By repeating the above operations, the rear part 164 of the excavation body 16 is maintained at a predetermined depth (with respect to the seabed surface), so that the buried depth of the elongated body 26 can be made constant.
