本発明は、電力ケーブル、通信ケーブルの如き電気ケー
ブルをマンホール内で余長取りする方法に関するものて
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for lengthening electrical cables, such as power cables and communication cables, within a manhole.
従来では、マンホール内ではケーブルの余長取りが行わ
れていないのでマンホール内に落下物等があつてマンホ
ール内のケーブル部分に障害が発生すると、一条のケー
ブル全長を引替えなければならなかつたので工事費及び
材料費がかさんで不経済であつた。In the past, excess cable length was not taken inside the manhole, so if something fell into the manhole and caused a problem with the cable inside the manhole, the entire length of the cable had to be replaced. It was uneconomical due to the high cost of materials and expenses.
このため、マンホール内でケーブルの余長取りをするこ
とが行われているが、この余長取りがコイル状であつた
のでケーブルの障害が発生し修理をするため余長部から
ケーブルを引出す時にキックを発生しケーブルが捩れて
ケーブルを修理することが困難であつた。本発明の目的
は、キックを発生することなくケーブルを引出すことが
できるようにマンホール内でケーブルを余長取りする方
法を提供することにある。For this reason, the excess length of the cable is removed inside the manhole, but since this excess length was in the form of a coil, cable failures occur and when the cable is pulled out from the extra length for repair. The kick occurred and the cable was twisted, making it difficult to repair the cable. SUMMARY OF THE INVENTION An object of the present invention is to provide a method for taking extra length of a cable in a manhole so that the cable can be pulled out without kicking.

する。Embodiments of the present invention will be described in detail with reference to the drawings.
Figures 1 and 2 show a method for taking extra length of a cable in a manhole according to the present invention, in which the cable 10 is laid through conduits 14 and 16 on both sides of the manhole 12, and inside the manhole 12, the cable 10 is laid in a figure-8 shape on a vertical plane. The extra length portion 18 is formed by elongating the length.

クを発生することがない。There are multiple concrete supports 2 inside the manhole 12?
is erected by appropriate means, and the extra length portion 18 is fixed to the column 20 by a fixture 22 at the portion where it intersects with the column 20.
In the embodiment of FIGS. 1 and 2, a cable connection 24 is provided within the manhole 12, and this cable connection is connected to the support column 20.
The extra length part 18 is fixed to this support with a fixture 26 across the
The cable part from the pipe line 14 side is connected to the cable part from the conduit 14 side. J Therefore, when a problem occurs in the cable 10 and the cable 10 is to be repaired, the fixture 22 can be removed from the support 20 and the extra length 18 can be extended and pulled out. In this case, the extra length has a figure 8 shape. Therefore, there will be no kick when withdrawing.

あるのでこの余長部をのばす場合にキングを発生するこ
とがないのでケーブルを容易に修理することができる。In the drawings, reference numeral 28 indicates a manhole, and reference numeral 30 indicates a manhole wall. According to the present invention, as described above, when there is a fault in the cable and the cable is to be repaired, it can be easily pulled out by extending the excess length, so there is no need to replace the cable, and the construction cost is reduced. It is economical because it saves on material costs, and since the extra length is in the shape of an 8, no kinging occurs when extending this extra length, so the cable can be easily repaired. .
尚、このケーブルの余長部は図示の実施例ではケーブル

てもよい。In the illustrated embodiment, the extra length of the cable is formed at the end of the cable and has a cable connection part in the manhole, but the extra length may be formed in the middle of one cable.
