図、第２図のように、長尺体１０に防護管２０をかぶせ
る。[Detailed explanation of the invention] Background and purpose of the invention Among long submarine cables (e.g. submarine cables, pipes, water pipes, etc.), there is usually a
As shown in FIG. 2, the protective tube 20 is placed over the elongated body 10.

なお防護管２０は上部２４と下部２６とに二つ割りにな
っていて、ボルトナツト２８で結合される。Note that the protective tube 20 is divided into two parts, an upper part 24 and a lower part 26, which are joined together with bolts and nuts 28.

また各防護管２０は着口３０と受口３２とで、継ぎ合わ
される。Further, each protection tube 20 is joined together at a port 30 and a socket 32.

ところが従来の防護管２０は、断面がほぼ円形で（第２
図）、重心Ｇがほぼ上下の中間にあるので、すわりがよ
くない。However, the conventional protective tube 20 has a substantially circular cross section (the second
(Figure), the center of gravity G is approximately halfway between the top and bottom, making it difficult to sit.

波や潮流などによって左右（軸方向に対して）移動し、
激しく摩耗して破損を起こし、長尺体１０の事故発生の
原因となつた。It moves left and right (relative to the axial direction) due to waves and currents,
This caused severe wear and damage, which caused the long body 10 to cause an accident.

本考案は、防護管２０の移動を防止すると共に、その底
部の摩耗を無くすようにしたものである。The present invention prevents movement of the protective tube 20 and eliminates wear on the bottom of the tube.

実施例第３．第４図のように、防護管の下部２６の底部に、座
２７を設ける。Example 3. As shown in FIG. 4, a seat 27 is provided at the bottom of the lower part 26 of the protective tube.

なお、座２７というのは、′その上にすわるための具ヨ
という意味である（岩波：国語辞典）。Note that za 27 means 'a tool for sitting on it' (Iwanami: Japanese dictionary).

座２７は、着口３０と受口３２を除いた部分に設ける。The seat 27 is provided in a portion excluding the inlet 30 and the socket 32.

その形は、はぼ直方体である。Its shape is a rectangular parallelepiped.

すなわち、両側面２７０は平行、底面２７２は平らで、
かつ側面２７０と直交する。That is, both side surfaces 270 are parallel, and the bottom surface 272 is flat.
and perpendicular to the side surface 270.

座２７は、防護管下部２６の底部を肉厚にして形成する
。The seat 27 is formed by making the bottom of the lower protective tube 26 thick.

あるいは、別に作っておいて、一体に接合する場合もあ
る。Alternatively, they may be made separately and joined together.

３４は移動防止用の金具で、たとえばＬ型金具を使用す
る（第５図）。34 is a metal fitting for preventing movement, for example, an L-shaped metal fitting is used (FIG. 5).

３６はボルト孔である。この金具３４を、第６図のよう
に、防護管２０の両側の岩４０の上に、アンカーボルト
３８によって固定する。36 is a bolt hole. The metal fittings 34 are fixed onto the rocks 40 on both sides of the protective tube 20 with anchor bolts 38, as shown in FIG.

なお、金具３４と座２７との間は、密着させても良いし
、少しくたとえば５ｍｍ＜らい）のすき間４２がで
きるようにしても良い。Note that the metal fitting 34 and the seat 27 may be brought into close contact with each other, or may be provided with a small gap 42 of, for example, 5 mm.

作用効果（１）金具３４によって防護管２０の移動が防止され、
その摩耗に基づく事故が防止される。Effect (1) The movement of the protective tube 20 is prevented by the metal fitting 34,
Accidents due to such wear are prevented.

（２）防護管２０の底部に座２７を一体に設けたので、
防護管２０の全体の重量が増し、それだけ動きにくくな
る。(2) Since the seat 27 is integrally provided at the bottom of the protective tube 20,
The overall weight of the protective tube 20 increases, making it more difficult to move.

（３）座２７は直方形か、またはそれに類似の形にした
ので、１岩４０上におけるすわりが良くなる。(3) Since the seat 27 is shaped like a rectangular parallelepiped or a similar shape, 1. It is easier to sit on the rock 40.

２また、比較的小さい金具３４で防護管２０移動を防
止できる。2. Furthermore, the protection tube 20 can be prevented from moving with the relatively small metal fitting 34.

すなわち、もし座２７を設けないとすると、金具３４の
高さは、少なくとも防護管２０の高さの半分くらいは必
要で、それ以下だと円筒形の防護管２０に乗り越えられ
る心配がある。That is, if the seat 27 is not provided, the height of the metal fitting 34 needs to be at least half the height of the protection tube 20, and if it is less than that, there is a risk that it will be climbed over by the cylindrical protection tube 20.

しかし、本案の場合は、座２７の側面２７０の平らの面
が全部３４に当って引っ掛かるので、金具３４が相当低
くても、それを乗り越えて行くことはできない。However, in the case of the present invention, all the flat surfaces of the side surfaces 270 of the seat 27 hit and get caught on the metal fitting 34, so even if the metal fitting 34 is quite low, it is impossible to climb over it.

Claims

[Scope of Claim for Utility Model Registration] In a submarine long body line in which a protective pipe 20 is placed over a long body 10 laid on a rock 40 on the seabed, a rectangular parallelepiped or a shape similar thereto is provided at the bottom of the protective pipe 20. seat 27, protective tube 20
At the same time, metal fittings 34 are fixed on the rocks 40 on both sides of the protective tube 20 in a position that contacts or is very close to the seat 27, so that the protective tube 20 is prevented from moving by the metal fittings 34. A long submarine railway line characterized by:
