ことが行われている。The number of telephone lines drawn by a building such as a building having a large number of telephone subscribers is large, and normally, the telephone line of all telephone subscribers is 1 at the duct (pipe) opening in the manhole of the building.
Collected in several places. In order to prevent such intrusion of water into the pipeline, the procedure shown in FIG. 7 is performed. That is, for the purpose of closing the vicinity of the conduit opening 2 of the conduit 3, the dam 4 is formed in the conduit 3 near the conduit opening 2 and in the conduit opening 2 by using a sponge or the like. Then, as shown in FIG. 8, the closed space between the two dams 4 is filled with a water-stopping material-forming material such as a two-component urethane foam polymer and hardened to form a water-stopping material 5 to form the conduit port 2. It is being blocked. By the way, in the case where the water is stopped in the pipeline 3 in this way, when the number of subscribers such as telephones is newly increased and the number of the cables 1 needs to be increased, the waterproof material 5 in the pipeline 3 is A hole is appropriately punched with a punch or the like, a saw is passed through the hole to increase the diameter of the hole, and the cable is passed therethrough. In addition, the replacement of the cable 1 is performed by drilling a ring-shaped hole around the cable 1 in the same manner as described above, pulling out the cable 1, and inserting a new cable.

ことによりケーブルの増設が行われる。Then, at a later date, when a new cable is added in the conduit 3 due to an increase in new telephone subscribers, etc., it is performed as follows. That is, using a tool such as a saw, as shown in FIG. 5, a hole A surrounded by an alternate long and short dash line is made in the waterproof material 5. At this time, the diameter of the hole A is set to be larger than the diameter of the pipe externally fitted to the newly inserted cable.
On the other hand, a pipe is externally fitted on the outer circumference of the newly added cable in the same manner as described above. And
The cable fitted with the pipe is inserted into the hole A. Next, a soft sponge is used to form a dam in two places between the newly inserted pipe and the water blocking material. Then, the closed space sandwiched between these two dams is filled with the same water-stopping material-forming material as described above and hardened, and the above-mentioned gap is filled, so that a cable is added.
