本発明は長尺海底ケーブル等の長尺ケーブルの工場接続
の鉛被接続法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a lead-sheathed connection method for factory connection of long cables such as long submarine cables.
（従来技術とその問題点）
長尺海底ケーブル例えば長尺海底型カケーブルは工場で
予め接続長尺化し後布設を行っている。(Prior art and its problems) Long submarine cables, such as long submarine cables, are connected in advance and made into long lengths at a factory, and then installed.
この接続の際の鉛被の接続は従来第１図の如き方法で行
っている。The connection of the lead sheath during this connection has conventionally been carried out by the method shown in FIG.

。That is, when the ends of the cable lead sheath (1) and the lead pipe for the connection part (2) are brought together, they are cut off so as to form a V-shaped groove (8) in cross section, and that part is butt welded (4). welded part(
4) Straddle the cable lead sheath (1) and the lead pipe for the connection part (2).
) The external lead pipe (6), which has been inserted in advance on one of the circumferences, is pulled back into the center V-shaped groove (8) and fillet welded (A), the external lead pipe (6) and fillet welding (a reinforcing layer (5) is applied across C (for example, formed by applying epoxy resin to glass tape and wrapping it around)
.
しかし乍らこのような方法によるものは下記のような欠
点がある。However, this method has the following drawbacks.
■ 溶接が３個所（（４）、（力、（７））あり、作業
時間が長い。■ There are three welding points ((4), (force, (7)), and the work takes a long time.
■ 曲げは、ケーブル鉛被（１）十補強層（５）、或い
は接続部用鉛管（２）十補強層（５）の強度に依存する
為又引張りはケーブル鉛被（１）と補強層（５）、或い
は接続部用鉛管（２）と補強層（５）の付着力に依存す
る為すみ肉溶接（７）近傍の強度が弱い。■ Bending depends on the strength of the cable lead sheathing (1) and the reinforcing layer (5), or the strength of the lead pipe for the connection (2) and the reinforcing layer (5). 5) Or, the strength near the fillet weld (7) is weak because it depends on the adhesion between the lead pipe (2) for the connection part and the reinforcing layer (5).
■ 衝合せ溶接（４）の直下に熱的に強くないケーブル
コアが存在する。又裏当金なしの衝合溶接となる為衝合
せ溶接（４）の溶接に細心の注意を要し充分な溶は込み
を期待出来ない。■ There is a cable core that is not thermally strong directly below the butt weld (4). In addition, since it is butt welding without a backing metal, great care must be taken in welding the butt weld (4), and sufficient penetration cannot be expected.
（発明の構成）
上記に鑑み本発明はこのような問題点を解消するため開
発されたものである。以下例示の第２図について本発明
の詳細な説明する。(Structure of the Invention) In view of the above, the present invention has been developed to solve these problems. The present invention will be described in detail below with reference to FIG. 2 as an example.
本発明に於いてはケーブル鉛被（１）端及び接続部用鉛
管（２）端を拡大し、その内部にスペーサー（３）を挿
入してケーブル鉛被（１）、接続用鉛管（２）間を衝合
溶接する（このため（１）、（２）端は衝合せたとき断
面Ｖ字状溝（８）を形成するよう切り落す）。In the present invention, the ends of the cable lead sheath (1) and the lead pipe for connection (2) are enlarged, and a spacer (3) is inserted inside them to form the cable lead sheath (1) and the lead pipe for connection (2). (For this purpose, the ends (1) and (2) are cut off so as to form a V-shaped groove (8) in cross section when they are brought together).
その外周に補強層（５）をスペーサー上の上記衝合溶接

来と同様例えばガラステープを用いエポキシ樹脂を塗布
しながら巻きつけて構成する。A reinforcing layer (5) is provided on the outer periphery of the spacer so as to straddle both sides of the convex portion where the welded portion of the butt weld is present. Note that the spacer is made of lead, for example, and has a cut in the axial direction, and is inserted through the cut. Further, the reinforcing layer (5) is constructed by wrapping the reinforcing layer (5) using, for example, a glass tape while applying an epoxy resin, as in the conventional case.
（発明の効果）
以上の様な本発明の方法によれば下記のような効果があ
る。(Effects of the Invention) The method of the present invention as described above has the following effects.
■ 溶接が１個所（（４） ）であり拡管も材質が鉛で
あるから容易である。従って作業時間が短かくてすむ。■ There is only one welding point ((4)) and pipe expansion is easy because the material is lead. Therefore, the working time is short.
■ 溶接部自体が裏当板付衝合溶接となり、スペーサー

張力に対する補強層（５）の効果が大きい、即ち補強層
（５）の剪断力が有効となる為、機械的強度が大きい。■ The weld itself is a butt weld with a backing plate, and the spacer serves as thermal protection for the cable core, so sufficient penetration can be expected. Also, for bending, use [spacer (3)) @ - (reinforcement layer (5)] - [butt welding (4) or cable lead sheath (1) or lead pipe for connection (2).
)]. Furthermore, since the welded portion is located in a convex portion, the effect of the reinforcing layer (5) on tensile force is large, that is, the shearing force of the reinforcing layer (5) becomes effective, resulting in high mechanical strength.
