防水混和物５とにより支持防水されている。1 and 2 show a conventional triplex type cable conduit mouth waterproofing device, in which the cable 11 has an internal backing 4 attached to a step 12 of the conduit 10 at the end of the conduit 10; A pipe between the inner backing 4 and the inlet backing 3, the artificial side backing 3 that is pressed and fixed in contact with the center metal fitting 2 and the side metal fittings 2A pressed by the tightening metal 1 that is pressed against the flange 13 via the bolt 6. Road 1
The cable 11 is supported and waterproofed by a putty-like waterproof mixture 5 filled between the inner side of the cable 11 and the outer periphery of the cable 11.

ング３取付部分を締付けている。The bolt 6 is fixed to the fastening fitting 1 via a flat washer 9 and a spring washer 8 by a nut 7 which is prevented from loosening, thereby tightening the mounting portion of the backing 3 on the entry side.
上記従来の防水装置の方式においては、単心ケーブルの
場合には、通電によるケーブルの伸縮により防水混和物
がケーブルの外周に沿って外部へ引き出され締付圧が低
くなり、従って水密性も低下する欠点があった。In the above-mentioned conventional waterproofing device system, in the case of a single-core cable, the waterproofing compound is drawn out along the outer circumference of the cable due to the expansion and contraction of the cable due to energization, lowering the tightening pressure and therefore reducing the watertightness. There was a drawback.
また、トリプレックス型ケーブルの場合はケーブルの伸
縮は余りないが撚合せ中心部に防水混和物を充填するこ
とが難しく水密性が充分でない欠点があった。Further, in the case of a triplex type cable, although the cable does not expand or contract very much, it is difficult to fill the center of the strand with a waterproofing compound, resulting in insufficient watertightness.
本考案の目的は、上記欠点を解消し、簡単な構造で取付

ランジに固定するフランジを設けてなるものである。This invention consists of a flanged pipe into which a cable is loosely fitted, which is attached to the flange at the end of the conduit with a waterproof packing interposed between them, and an internal compound leak-stop packing which is prevented from hanging on the inner end of the flanged pipe, and a flange. Compound outflow ratio between the packing attached to the flange side of the pipe and the inside of the flanged pipe and the outer periphery of the cable between the packing and the above-mentioned two backings, and the foamed compound formed after being filled between the packing and the outer circumference of the cable, the waterproof backing, the flanged pipe, and the compound outflow. A flange is provided to fix the ratio backing to the flange via a tightening bolt.
以下本考案の管路口防水装置の一実施例を第３図、第４
図により説明する。An embodiment of the pipe mouth waterproofing device of the present invention is shown below in Figures 3 and 4.
This will be explained using figures.

。The inside of the flanged pipe 15 and the cable 11 between the compound outflow ratio backing 16 on the flange side of the flanged pipe 15 and the internal compound outflow ratio backing 21
After being injected and filled from the compound injection hole 24, a foamed compound 23 having closed cells made of foamed urethane rubber, silicone rubber, etc. and having good adhesiveness and elasticity is foamed between the outer periphery and the outer periphery of the compound. It is arranged.
発泡コンパウンド２３は注入後発泡処理されるので介在
物２２により形成された進入路を介しケーブル撚合せ中
心部にも充分に浸透充填され、また、ケーブル１１の外
周ならひ゛にフランジ付パイプ１５の内周側にも水密的
に接着している。Since the foaming compound 23 is foamed after being injected, it is sufficiently penetrated and filled into the center of the cable twisting through the entrance path formed by the inclusions 22. Also, if it is the outer periphery of the cable 11, it will be completely filled on the inner periphery of the flanged pipe 15. It is also watertightly bonded.
上記したようにこの防水装置は、管路１０内壁直接では

単な構造であり、取付作業も容易で、確実に水封するこ
とができる。As described above, this waterproofing device uses a flanged pipe 15 in consideration of the fact that if the inner wall of the pipe 10 is directly attached, the foaming compound 23 will not have sufficient adhesion due to rust and other deposits on the inner wall, and water sealing cannot be performed reliably. Using flanged pipe 15
It has a simple structure in which it is fixed to the flange 13 via the waterproof backing 14, and the installation work is easy and it can be reliably sealed against water.
