て布設を行うものである。 The present applicant has previously proposed a cable installation method as shown in FIGS. 1 to 4, which is suitable for cases where the cable length is long or the installation route is curved. In addition, in the figure, 1A to 1E are manholes, 2A to 2D are pipes that communicate between the manholes,
L is the section where one cable is to be laid, 3 is the long cable to be laid, 4 is the drum around which the long cable 3 is wound, 5A and 5B are the pulling machines, 6A and 6B are the lead wires, and 7 is the part of 8. This is a letter-shaped cable storage section. That is, in this laying method, as shown in FIG. 1, a drum 4 on which the cable 3 to be laid is wound is installed at the middle point of the laying section, the cable 3 is pulled out from this drum 4, and the cable 3 is laid as shown in the figure. The cable is laid from the middle point to one end of the cable section using the pulling machine 5A and the lead wire 6A, and then the remaining cable 3 is pulled out from the drum 4 at the middle point as shown in FIGS. 2 and 4. Then, it is stored in a figure 8 shape at the intermediate point to form a figure 8 cable storage section 7, and finally from this figure 8 cable storage section 7, the cable 3 is connected as shown in Fig. 3.
The cable is pulled out and laid from the intermediate point to the other end of the laying section using the installation machine 5B and the lead wire 6B, thereby laying the entire length of the laying section.
なお、この布設方法は、地下の管路のみなら
ず、地上のピツト或は架空の電柱上等へのケーブ
ル布設にも同様に適用できるものである。 Note that this installation method can be applied not only to underground conduits but also to installation of cables in above-ground pits or on overhead utility poles.
このような布設方法をとることにより、ケーブ
ル３の１条長を長くしても布設時にケーブル３に
かかる引張力を従来より大幅に低減して布設を行
える利点がある。また、８の字形ケーブル蓄線部
７を形成することによりケーブル３に捩れを発生
させることなく円滑に布設を行うことができる。 By adopting such a laying method, there is an advantage that even if the length of one cable 3 is increased, the tensile force applied to the cable 3 during laying can be significantly reduced compared to the conventional method. Further, by forming the figure-8 cable storage section 7, the cable 3 can be laid smoothly without twisting.
しかしながら８の字形ケーブル蓄線部７は特に
８の字の交差部分が他の部分より高く積重なるの
でその形状の維持が難しく、形くずれのためにも
つれを発生させ易い欠点がある。 However, the figure 8-shaped cable storage section 7 has the disadvantage that it is difficult to maintain its shape, particularly at the intersections of the figure 8, which are stacked higher than other parts, and tangles are likely to occur due to the shape being distorted.
本発明の目的は、８の字形の形状の維持を確実
に行うことができる８の字形蓄線方法を提供する
にある。 An object of the present invention is to provide a figure-8 wire storage method that can reliably maintain the figure-8 shape.
本発明に係る８の字形蓄線方法は、ケーブルを
８の字形に蓄線するに際し、８の字形をなすケー
ブルの各中間部分をケーブル支持台の支持面方向
に順次位置をずらしつつそれぞれ仮留めすること
を特徴とするものである。 In the figure-8 wire storage method according to the present invention, when storing cables in a figure-8 shape, each intermediate portion of the cable forming the figure-8 shape is temporarily fixed while sequentially shifting the position in the direction of the support surface of the cable support stand. It is characterized by:
以下本発明の実施例を第５図を参照して詳細に
説明する。本実施例では平行する２つのケーブル
支持台８を用い、これらケーブル支持台８を横切
るようにしてケーブル３を８の字形に蓄線するも
ので、８の字形をなすケーブル３の各中間部分を
ケーブル支持台８の支持面方向に順次位置をずら
しつつそれぞれクランプ具９でケーブル支持台８
に仮留めするものである。 Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. In this embodiment, two parallel cable support stands 8 are used, and the cable 3 is stored in a figure 8 shape by crossing these cable support stands 8, and each intermediate portion of the cable 3 forming the figure 8 shape is While sequentially shifting the position in the direction of the support surface of the cable support stand 8, the cable support stand 8 is moved using the clamp tool 9.
It is temporarily fastened to.

発生を確実に防止することができ、蓄線部７から
ケーブル３を引出す際にもつれを発生させること
なく円滑にケーブル３の引出しを行うことができ
る。 When the cable 3 is stored in this way, the intersection of the figure 8 is shifted in the direction of the support surface of the cable support stand 8, so that part does not become high and deformation can be reliably prevented. When the cable 3 is pulled out from the wire storage section 7, the cable 3 can be smoothly pulled out without causing any tangles.
なお、ケーブル支持台８は１台でもよい。 Note that the number of cable support stands 8 may be one.

しを行うことができる。 As explained above, in the present invention, each intermediate portion of the figure-8-shaped cable is temporarily fixed while sequentially shifting its position in the direction of the support surface of the cable support base, so that deformation can be reliably prevented. can. Therefore, according to the present invention, when pulling out the cable from the wire storage section, the cable can be pulled out smoothly, and the cable can be pulled out without twisting the cable.
