本考案はケーブル管路に水が流入しないように
管路口を閉塞する防水栓に関するものである。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a waterproof plug that closes a conduit opening to prevent water from flowing into a cable conduit.
地下ケーブル管路の管路口はマンホール内で開
口しているのでケーブルが引き込まれていない空
の管路にはケーブルに入つた雨水が管路口から流
入し、その管路に新たにケーブルを引き入れる際
には障害となつており、このため空の管路の管路
口には防水栓を装着して閉塞していた。
The pipe entrance of underground cable conduits opens inside the manhole, so rainwater that has entered the cables flows into empty pipes where no cables are drawn, and when new cables are drawn into the pipes. For this reason, the pipe entrances of empty pipes were closed off with waterproof plugs.
前記のように空の管路口に防水栓を装着しても
長期間経過すると空のケーブル管路内に地下水等
の水が滞留し、この滞留水が多量になるとその水
圧で管路口に装着されている防水栓が押し出され
脱落することがあつた。
As mentioned above, even if a waterproof plug is attached to an empty pipe entrance, after a long period of time, water such as groundwater will remain in the empty cable pipe, and when this accumulated water becomes large, the water pressure will cause it to be attached to the pipe entrance. In some cases, the waterproof plug that was installed was pushed out and fell off.
このため本出願人は水圧を受けても管路口から
脱落しないようにした実開昭54−115595号の防水
栓を提案したが、この防水栓では多量の水が滞留
している空の管路に新たにケーブルを引き入れる
際に防水栓を引き抜くと、管路内の多量の水が管
路口から勢いよく噴出するので作業の障害になる
という問題点があつた。 For this reason, the present applicant proposed a waterproof plug in Japanese Utility Model Application No. 115595/1983 which was designed to prevent it from falling out of the pipe opening even when subjected to water pressure. There was a problem in that if the waterproof plug was pulled out when a new cable was being brought in, a large amount of water inside the pipe would gush out from the pipe opening, which would hinder the work.
また、前記提案の防水栓では管路内がマホール
内の外気圧より減圧になつている場合には、管路
口に差し込まれている防水栓を引き抜くことが困
難であるという問題点があつた。 Furthermore, the proposed waterproof plug has a problem in that it is difficult to pull out the waterproof plug inserted into the pipe opening when the pressure inside the pipe is lower than the outside pressure inside the main hole.
そこで本考案は、ケーブル管路内に多量の水が
滞留していても管路口から防水栓を引き抜く際に
急激に噴出することがないようにし、かつ管路内
が減圧状態の場合にはその減圧状態を解消するこ
とができる防水栓を提供するものである。 Therefore, the present invention has been developed to prevent water from suddenly gushing out when the waterproof plug is pulled out from the pipe opening, even if a large amount of water remains in the cable pipe, and to prevent water from suddenly gushing out when the water plug is pulled out from the pipe opening, and to prevent water from suddenly gushing out when the water plug is pulled out from the pipe opening. To provide a waterproof plug that can eliminate a reduced pressure state.

急激に噴出するようなことはなくなる。 When removing this waterproof plug, leave it attached to the cable conduit entrance and remove the cap nut screwed onto the tip of the hollow core tube, and the water remaining in the conduit will flow out from the tip of the hollow core tube. Therefore, it becomes possible to receive this water in a container or the like, and there is no possibility that a large amount of water suddenly spews out the moment it is pulled out from the pipe opening, unlike the waterproof plug disclosed in the above-mentioned patent application.
またケーブル管路内が減圧状態の場合でも、中

A waterproof plug constructed of a rubber disc packing 4, a stop plate 5, a cylindrical nut 7, and a cap nut 8 is as shown in the figure. To install this at the cable conduit entrance, hold the cylindrical nut 7 part with your hand at the conduit entrance A where the empty conduit with no cables is opened in the manhole, and hold the fixing disk 2, If you insert the movable disc 3 and the rubber disc packing 4 sandwiched between them and screw the cylindrical nut 7, the end of the cylindrical nut 7 will move the movable disc 3 to the fixed disc 2.
The annular portion 41 of the rubber disk packing 4 is pressed toward the fixed disk 2 and the movable disk 3, and is sandwiched between the opposing annular inclined plate portions 21 and 31 of the movable disk 3.
42 is compressed by both inclined plate portions and pushed outward, so that the outer circumferential surfaces of the annular portions 41 and 42 are strongly pressed against the inner circumferential surface of the conduit port A, and are fixed in pressure contact.

ようなおそれはない。 In this way, the cable conduit opening is watertightly closed by the rubber disc packing 4 of the waterproof plug and the cap nut 8, so even if rainwater enters the manhole, it will be prevented from entering the cable conduit. Become. Since the annular parts 41 and 42 of the rubber disc packing 4 are strongly pressed against the inner circumferential surface of the pipe port, and the stop plate 5 is in contact with the front surface of the pipe port A, a large amount of water remains in the pipe. Even when subjected to water pressure of

うことにより安全に排水させることができる。 When a new cable is introduced and installed in an empty cable conduit whose waterproof plug is attached to the conduit opening as described above, first, the cap nut 8 screwed onto the tip of the hollow core tube 1 is removed. If a large amount of water remains in the pipe, when the cap nut 8 is removed, water will leak from the opening at the tip of the hollow core tube through the drainage/ventilation hollow channel 12 of the hollow core tube 1. Therefore, the water can be drained safely by immediately applying a water container, hose, etc. to this opening at the end.

水栓を取外すことになる。 After the accumulated water in the pipe is drained in this way, the cylindrical nut 7 is loosened to fix the movable discs 2 and 3.
Annular parts 41 and 42 of the rubber disc packing 4 according to
When the pressure is released, the pressure contact between the outer circumferential surface of the annular part and the inner circumferential surface of the pipe port is released, and the waterproof plug can be removed safely and easily without a large amount of accumulated water gushing out from the pipe port. Become. If water does not come out from the opening at the tip of the hollow core tube 1 even after removing the cap nut 8 as described above, it means that there is no accumulated water in the cable conduit, so immediately loosen the cylindrical nut 7. The waterproof plug will need to be removed.

る。 In addition, if the pressure inside the cable conduit is lower than the outside pressure inside the mahole, removing the cap nut 8 at the tip of the hollow core tube 1 as described above will allow drainage and ventilation of the hollow core tube. Since the inside of the pipe and the outside air are communicated through the hollow passage 12 and the reduced pressure state is eliminated, the waterproof plug can be easily removed.

As mentioned above, the waterproof plug of the present invention has a hollow core tube 1 having a structure having a hollow passage 12 for drainage and ventilation, and a cap nut 8 at its tip opening.
When removing the waterproof plug from the cable conduit entrance, the cap nut 8 screwed onto the tip of the hollow core tube 1 is first removed, so even if there is a large amount of water stagnant in the conduit. Drainage can be done safely, and there is no need to worry about the sudden gushing of water that hinders work.
また、管路内が減圧状態になつている場合でも
中空心管1先端の袋ナツト8を外して外気と連通

き、マホール内における防水栓の取扱い作業が容
易になるものである。 Furthermore, even if the inside of the pipe is in a reduced pressure state, the reduced pressure state can be resolved by removing the cap nut 8 at the tip of the hollow core tube 1 and communicating it with the outside air, making it easier to handle the waterproof plug inside the mainhole. It becomes easier.

である。 In addition, to attach the waterproof plug to the pipe port, all you have to do is hold the cylindrical nut 7 in your hand, insert it into the pipe port, and screw this cylindrical nut 7, so the handling work is extremely easy. Since the outer circumferential surfaces of the annular parts 41 and 42 of No. 4 are strongly pressed and fixed against the inner circumferential surface of the conduit opening, even if rainwater flows into the mahole, it is not only possible to completely prevent it from entering the conduit. The waterproof plug installed in this manner has no fear of coming off from the pipe opening even if it is subjected to the water pressure of a large amount of water stagnant in the pipe or other external force. Furthermore, stop plate 5
Since it is in contact with the front surface of the conduit port A, the waterproof plug is not pushed too far into the conduit port.
