Description
【発明の詳細な説明】 本発明は電カケープルの布設方法に関する。[Detailed description of the invention] The present invention relates to a method for laying an electric cable.
電カケープルは地下の管路内に布設されることが多いが
、管路は地下の他の構造物との関係で曲折していること
が多く、電カケープルの布設には摩擦という大きな問題
があった。Electric power cables are often installed in underground conduits, but the conduits are often bent in relation to other underground structures, and the installation of electric power cables poses a major problem of friction. Ta.
従来この問題を解決する方法として、管路内に油を塗布
し、摩擦力を低減させることも提案されているが、この
方法は、油を管内に薄くしか塗布できず、従って摩擦係
数の大幅な低減には寄与せず、さらに、油はケーブルの
防蝕層に化学的影響を及は゛し、ケーブル寿命を短かく
する欠点があり、実用化されていない。Conventionally, as a method to solve this problem, it has been proposed to apply oil inside the pipe to reduce the frictional force, but this method only allows oil to be applied thinly inside the pipe, and therefore the coefficient of friction increases significantly. In addition, oil has the disadvantage of chemically affecting the cable's corrosion protection layer and shortening the cable's lifespan, so it has not been put to practical use.
本発明は斯かる状況に鑑み、前記の摩擦力を低減し、電
カケープルに無理なく容易に布設を行うことのできる方
法を提供することを目的とする。In view of this situation, it is an object of the present invention to provide a method that reduces the above-mentioned frictional force and allows easy and reasonable installation of power cables.
本発明の構成を実施例を示す図面を参照して具体的に説
明する。The configuration of the present invention will be specifically explained with reference to drawings showing embodiments.
第１図において、１は管路であり、この管路１の内面に
塗布器２によって滑剤３を塗布する。In FIG. 1, 1 is a conduit, and a lubricant 3 is applied to the inner surface of the conduit 1 by an applicator 2.
塗布器２はワイヤー４によって一端から他端へ引かれ、
滑剤３を管路１の全長に亘って塗布する。The applicator 2 is drawn from one end to the other by a wire 4;
A lubricant 3 is applied over the entire length of the conduit 1.
滑剤３は第２図に示すように予め管路１内の複数箇所に
滑剤の山３０として山積されていると塗布に便利である
。It is convenient to apply the lubricant 3 if it is piled up in advance as lubricant mounds 30 at a plurality of locations within the conduit 1 as shown in FIG.
滑剤３は例えばタルク（滑石の粉末）もしくはマイカ（
雲母の微粒片）を４０〜７０重量パーセントに対して水
を３０〜６０パーセント混練したものである。The lubricant 3 is, for example, talc (talcum powder) or mica (
It is made by kneading 40 to 70 percent by weight of mica fine particles) with 30 to 60 percent of water.
このような滑剤３を管路１に塗布した復電カケープルを
管路１内に引き入れたところ、引き入れ時の静止摩擦係
数は０．３１、動摩擦係数は０．２５であり、充分に張
力を低減することができたものである。When the power recovery capule with such lubricant 3 applied to the pipe line 1 was drawn into the pipe line 1, the static friction coefficient at the time of drawing was 0.31 and the dynamic friction coefficient was 0.25, which sufficiently reduced the tension. It was possible to do so.
塗布器２は例えば第３図に示すようにゴム製円板状体２
１を二つ引張シャフト２２によって連結した構造であり
、円板状体２１の外周には溝２３が設けられている。The applicator 2 is, for example, a rubber disc-shaped body 2 as shown in FIG.
1 are connected by a tension shaft 22, and a groove 23 is provided on the outer periphery of the disk-shaped body 21.
このような塗布器３であれば管路１の内壁に−様に滑剤
３を塗布することができ、布設張力及び側圧の低減を図
ることができる。With such an applicator 3, the lubricant 3 can be applied to the inner wall of the conduit 1 in a negative manner, and the installation tension and lateral pressure can be reduced.
塗布器２に設けられた溝２３の形状としては歯車型、鋸
歯状型、矩形型、円弧状型などが上げられる。Examples of the shape of the groove 23 provided in the applicator 2 include a gear shape, a sawtooth shape, a rectangular shape, and an arc shape.
本発明の布設方法であれば滑剤により電カケープル布設
時の摩擦力を低減し、電カケープルに無理な張力をかけ
ることなく、容易に布設を行うことができるものである
。According to the installation method of the present invention, the frictional force during installation of the power cable is reduced by the lubricant, and the installation can be easily carried out without applying excessive tension to the power cable.
