【発明の詳細な説明】
本発明は所定間隔毎にマンホールを有する管路内にケー
ブルを布設する方法の改良に係る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method of laying a cable in a conduit having manholes at predetermined intervals.
第１図に示すように所定間隔毎にマンホール１゜２．３

ことが行なわれる。As shown in Figure 1, manholes are spaced 1°2.3 at regular intervals.
When installing a cable 5 in a conduit 4 that has The cable installation device 9 takes over the cable.
一般に、この種網８に細いスチールワイヤー等を用いる
場合はウィンチで巻取りを行ない、太いロープを用いる
場合は無端ベルト式のものによってロープを挾みつけて
引取る方法がとられている。Generally, when a thin steel wire or the like is used for this kind of net 8, it is wound up with a winch, and when a thick rope is used, the rope is held in place by an endless belt type.
ところが、ウィンチによる場合はウィンチ用のスチール

ように引取り側にロープの山ができるという難点があっ
た。However, when using a winch, it is necessary to lead the steel wire for the winch from the opposite side of the cable installation section to the location where the cable is to be laid, and when using an endless belt type, if the rope is not thick, it has to be pulled by pinching it. Since it cannot be removed, when using thick and long ropes, there is a problem in that a pile of rope forms on the receiving side as shown in Figure 1.

るケーブル布設方法に関する。The present invention has been made in view of the above points, and provides a first cable laying device having a pair of opposing endless belt pulling mechanisms for pulling the tip of a flexible seed net, one end of which is tied to the tip of the cable to be laid. The cable is taken up by winding it around an endless belt of either fj, and then the side net is taken up using a second cable laying device, and the seed net is taken up in the same manner as the said taking up, while the first cable The present invention relates to a cable laying method characterized in that the cable is clamped and fed by an endless belt mechanism of a laying device.
以下その方法を実施例によって説明する。The method will be explained below using examples.
第２図において、まずケーブルを布設すべき管路１０内
をマンドレル等により清掃する。In FIG. 2, first, the inside of the conduit 10 where the cable is to be laid is cleaned using a mandrel or the like.
このときマンドレルの後端に麻ロープ等の柔軟な種網を
結束し管路の清掃終了と同時に各管路に図のように種網
１１，１２の通線が完了するようにする。At this time, a flexible seed net such as a hemp rope is tied to the rear end of the mandrel so that the threading of the seed nets 11 and 12 through each pipe is completed as shown in the figure at the same time as the cleaning of the pipes is completed.
この管路の長さが短いときは種網１１と１２の端を結束
するか継ぎ目の無い１本の種網を使用する。When the length of this pipe is short, either the ends of the seed nets 11 and 12 are tied together, or one seamless seed net is used.
次にマンホールのいくつかに無端ベルト式ケーブル布設
装置１３．１４を設置する。Next, endless belt type cable laying devices 13, 14 are installed in some of the manholes.
その後刺網１１の一端をケーブル布設装置１３の無端ベ
ルト１５に第３図に示すように巻回して固定しケーブル
布設装置１３を始動させると種網１１は無端ベルト１５
外周に巻回されケーブル１６が管路に引込まれる。Thereafter, one end of the gill net 11 is wound and fixed around the endless belt 15 of the cable laying device 13 as shown in FIG.
The cable 16 is wound around the outer circumference and drawn into the conduit.
そして、ケーブル先端１７がケーブル布設装置１３に挾
み込まれたら種網１１を外し次の種網１２の一端をケー
ブル先端に結束する。When the cable tip 17 is inserted into the cable laying device 13, the seed net 11 is removed and one end of the next seed net 12 is tied to the cable tip.
今度はケーブル布設装置１４によって種網１２を先の方
法と同様にして引取る一方、ケーブル布設装置１３でケ
ーブル１６を挾みつけて送る。This time, the seed net 12 is picked up by the cable laying device 14 in the same manner as in the previous method, while the cable 16 is pinched and sent by the cable laying device 13.
以上詳述した本発明の方法によれば、種網が、布設装置
の無端ベルトに巻回できる程度に柔軟であるからマンホ
ール内での取り扱いおよび搬入作業が容易である。According to the method of the present invention described in detail above, since the seed net is flexible enough to be wound around the endless belt of the laying device, it is easy to handle and carry it into the manhole.
また、ケーブル布設装置に無端ベルト式のものを使用し
て、種網の巻取りと送りの両方の作用をさせるので布設
作業効率が良い。Furthermore, since an endless belt type cable laying device is used to perform both winding and feeding of the seed net, the laying work is efficient.
