本発明はケーブル埋設機に関し、４！に水底に通信ケー
ブル等を埋設するケーブル埋設機に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cable burying machine, and includes 4! This invention relates to a cable burying machine for burying communication cables, etc. at the bottom of water.
第３図（ａ）および（ｂ）は従来のケーブル埋設機の一
例を示す縦断面図および平面図である。FIGS. 3(a) and 3(b) are a longitudinal sectional view and a plan view showing an example of a conventional cable burying machine.
従来、この種のケーブル埋設機に於ては、ケーブル埋設

掘シ起こされた土砂１８の上を、ケーブル埋設機本体１
１のそりｌｌａが通過するような構造となっていた。Conventionally, in this type of cable burying machine, a groove 17 is created on the bottom surface of the water by a plow 15, which is a digging blade of the cable burying machine main body 11.
The cable 13 via the cable inlet port 14 is put into the u17 and held down by the cable presser car 16, and the cable 13 is moved by the movement of water and the like, and the earth and sand 18 on both sides of the groove 170 are removed.
It was designed so that it would naturally collapse and be buried. Also,
The cable burying machine main body 1 is placed over the excavated earth and sand 18.
The structure was such that the sled lla of No. 1 could pass through.
上述した従来のケーブル埋設機は、ケーブルを溝の中に

る。The conventional cable burying machine mentioned above simply drops the cable into the trench, and as time passes, the cable will naturally move, etc., and the earth and sand on the walls on both sides of the trench will be removed. However, there is no guarantee that the soil will be deposited on the cable, and the cable may be buried to a sufficient extent immediately after it is laid, so depending on the underwater topography, the cable may The disadvantage is that there is a risk of it floating out of the groove.
さらに従来のケーブル埋設機に於ては、鋤で掘り起こさ
れた土砂の上を埋設機のそりが通過する為に、埋設機が
持ち上げられ、溝の掘削深度が充分に得られなくなる可
能性がある。Furthermore, with conventional cable burying machines, the burrowing machine's sled passes over the earth and sand dug up by the spade, which causes the burying machine to be lifted up, potentially making it impossible to obtain a sufficient digging depth for the trench. .
本発明は上記従来の欠点を除去し、掘削した土砂を溝の
両側に積み上げ且つケーブル布設後の溝の中に埋め戻し

、布設されたケーブル３を埋設する。The cable burying machine main body 1 installed on the bottom of the water is towed by a preceding laying ship 21 via a towing wire 2. The cable 3 to be laid/buried is placed in the laying ship 210 and the cable tank 2.
2, the cable passes through the cable engine 23 and is led to the cable introduction port 4 of the cable burying machine main body 10. cable 4
Cable presser wheel 6 is placed in #9 excavated by plow 5.
laid down by The plow 5 is mounted on the upper side of the cable burial machine main body 1 so as to be suspended downward from the plate 7, so the plow 5 excavates the earth and sand with a 7-ply movement. are piled up on both sides of groove 9. This earth and sand 10 is returned to the groove 9 by a backfilling machine 8 installed behind the cable presser car 6, and buries the laid cable 3 therein.
なお、ケーブル埋設機本体１のそｉｌａ、ｌｂは、溝９
に対して両側に分割された形状となりているので、掘シ
起こされて積み上げられた土砂１０を踏み潰すようなこ
とがない。Note that the sides ila and lb of the cable burying machine main body 1 are the grooves 9.
Since it has a shape that is divided into both sides, there is no chance of trampling on the earth and sand 10 that has been dug up and piled up.
以上説明したように本発明は、本体の上側から吊り下げ

効果がある。As explained above, the present invention uses the excavation means suspended from the upper side of the main body and the backfilling section provided at the rear of the main body. Since it can be buried, it has the effect of protecting the installed cable from ship anchors and fishing hazards.
また、従来の埋設機のように掘り起こした土砂がそシの
下に入らずに鋤の両側に排除される為に、埋設機が持上
げられることが無いため、充分な溝の掘削深度を得るこ
とができるし、また埋設機の走行安定性も向上する。In addition, unlike conventional burying machines, the excavated soil is removed to both sides of the plow instead of going under the plow, so the burying machine does not have to be lifted, making it possible to obtain a sufficient trench digging depth. This also improves the running stability of the burial machine.
さらに、後部に土砂埋戻し機を有することにより１．多
少埋設機を曳航する張力は大きくなるが、埋設機の転倒
防止に役立つ。Furthermore, by having an earth and sand backfilling machine at the rear, 1. Although the tension required to tow the burying machine is somewhat increased, it helps prevent the burying machine from tipping over.
なお、本発明のケーブル埋設機は水底のみならず、陸上
に於ても使用が可能である。The cable burying machine of the present invention can be used not only at the bottom of the water but also on land.
