【発明の詳細な説明】
本発明は投錨海域等で海底に布設（埋設も含む）されて
いる海底ケーブルや送水管等の長尺体を錨等から防護す
る海底における長尺体の防護装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a protection device for long bodies on the seabed, which protects long bodies such as submarine cables and water pipes laid (including buried) on the seabed in anchorage areas etc. from anchors, etc. It is something.
投錨海域或は漁業海域等の海底に長尺体が布設されてい
る場合には、錨や漁具等が海底に沿って引き摺られるの
で、これら錨や漁具等で長尺体が損傷される欠点がある
。When a long body is laid on the seabed in an anchorage area or a fishing area, the anchor and fishing gear are dragged along the seabed, so there is a disadvantage that the long body may be damaged by the anchor or fishing gear. be.
本発明の目的は、海底に布設されている長尺体を効果的
−に防護できる海底における長尺体の防護装置を提供す
るにある。An object of the present invention is to provide a protection device for a long body on the seabed, which can effectively protect a long body installed on the seabed.
以下本発明の実施例を図面を参照して詳細に説明する。Embodiments of the present invention will be described in detail below with reference to the drawings.
本実施例の防護装置は、第１図に示すように、海底１に
布設されている海底ケーブルや送水管等の長尺体２の両
側に例えば５０〜１００ｍ程度の間隔をおき且つその長
手方向に沿って防護用長尺体３をそれぞれ並設し、これ
ら防護用長尺体３で長尺体２を防護するものである。As shown in FIG. 1, the protection device of this embodiment is a long body 2, such as a submarine cable or water pipe, installed on the seabed 1, with an interval of, for example, about 50 to 100 meters on both sides, and in the longitudinal direction. Protective elongated bodies 3 are arranged in parallel along each line, and the elongated body 2 is protected by these protective elongated bodies 3.
防護用長尺体３は、例えば３０〜５０ｍ程度の間隔で設
置されたシンカー４と、これらシンカー４の相互間を連
結している金属ロープ又はチェーン等の連結条体５とで
構成している。The protective elongated body 3 is composed of sinkers 4 installed at intervals of, for example, about 30 to 50 m, and a connecting strip 5 such as a metal rope or chain that connects the sinkers 4 with each other. .
連結条体５は、本実施例ではそれぞれ３条用い、各シン
カー４に固定されているフツク６に連結している。Three connecting strips 5 are used in this embodiment, and are connected to hooks 6 fixed to each sinker 4.
シンカー４は、本実施例では第２図及び第３図に示すよ
うに、横断面が略半円形状をなす形状にして重心を下側
に位置させ、布設船から防護用長尺体３を海中に沈める
ときこのシンカー４が横になったり、逆になったりしな
いようにし、且つ半円形状により海底に設置されたとき
波圧抵抗が小さくなるようにしている。In this embodiment, as shown in FIGS. 2 and 3, the sinker 4 has a substantially semicircular cross section, and its center of gravity is located at the lower side, so that the long protective body 3 can be removed from the laying ship. When submerged in the sea, the sinker 4 is prevented from lying sideways or upside down, and its semicircular shape reduces wave pressure resistance when installed on the seabed.
このようなシンカー４を実施例では鉄筋コンクリートで
形成し、その重量は１〜５ ｔｏｎ程度としている。In the embodiment, such a sinker 4 is made of reinforced concrete, and its weight is about 1 to 5 tons.
以上のように防護用長尺体を並設しておくと、錨や漁具
等が海底１に沿って引き摺られて来た場合には、先ず防
護用長尺体３に引っ掛り、各シンカー４の重量で錨や漁
具等の進行を阻止するから、長尺体２を防護できる。By arranging the protective elongated bodies in parallel as described above, when an anchor, fishing gear, etc. is dragged along the seabed 1, it will first get caught on the protective elongated body 3, and each sinker 4 Since the weight of the anchor and fishing gear is prevented from advancing, the elongated body 2 can be protected.
また、上記のようなシンカー付の防護用長尺体３は、布
設船から海中に順次落して行くことにより布設を行うこ
とができる。Moreover, the protective elongated body 3 with a sinker as described above can be laid by successively dropping it into the sea from a laying ship.
従って、急流等の理由によりダイバーがもぐれないよう
な海域でも容易に防護作業を行うことができる。Therefore, protection work can be easily carried out even in sea areas where divers cannot escape due to rapid currents or the like.
なお、防護用長尺３の布設は海底ケーブル等の長尺体２
の布設後に布設してもよく、或は布設前に予め布設しそ
の後に長尺体２を布設してもよいことは勿論である。In addition, when laying the protective long body 3, it is necessary to install the long body 2 such as a submarine cable.
Of course, the elongated body 2 may be installed after the installation, or the elongated body 2 may be installed in advance after the installation.
以上説明したように本発明では、海底に布設されている
長尺体の両側に間隔をおいてシンカー付の防護用長尺体
を並設したので、錨や漁具等から長尺体を効果的に防護
することができる。As explained above, in the present invention, protective elongated bodies with sinkers are installed at intervals on both sides of the elongated body laid on the seabed, so that the elongated body can be effectively removed from anchors, fishing gear, etc. can be protected against.
