If compressed air is sealed in the airtight space surrounded by the elastic body of the air plug, the band of the elastic body will be tightened with the exception of the part outward. The air plug is fixedly set inside the sewer pipe because it expands and comes into close contact with the inner wall of the sewer pipe. At the same time, a portion of the elastic body covering the outer tube portion where the inner tube is not installed expands inward to clamp the hose, so that the hose is connected to the air plug.

内管３との間に挟持される形となる。FIG. 1 is a sectional view of an air plug l according to the present invention.
In the figure, 2 is a highly rigid outer tube made of metal or the like,
An inner tube 3 having high rigidity is also partially housed inside the outer tube 2, and a portion of the inner tube 3 is connected to the outer tube 2 as shown in the figure.
It protrudes slightly outward in the axial direction. The entire outer tube 2 is covered with a highly airtight elastic bag-like elastic body 4 that is stretchable, and a sealed space S is formed inside the elastic body 4. Therefore, a part of the inner peripheral portion of the first elastic body 4 is held between the outer tube 2 and the inner tube 3.

６が介設されている。Thus, one or more air plugs 1 are used as water stop plugs in a pipe repair method, for example, as shown in FIG. That is, FIG. 2 is a sectional view showing a method of bypassing water in a pipe in the pipe repair method, and as shown in the figure, the air plug 1 is set at the inner end of the pipe 11 and It functions to block water in the channel 11 and to connect to the end of the hose 12.
In this case, the hose 12 is connected to a tank 14 installed on the ground via a manhole 13.
Another hose 15 is led out from the
6 is interposed.

よい。By the way, in the state shown in FIG. 2, the lining is constructed for the pipe line 17.
Is it necessary to prevent water from flowing into the area? For this purpose,
The pump 16 is driven, and the water in the conduit 11 blocked by the air plug l is sucked up from the hose 12, one end of which is connected to the air plug l, to the tank 14, and then from the hose 15 to another conduit ( (not shown).

Next, as shown in FIG. 4, the pipe 18 connected to the end of the hose 12 is placed inside the outer tube 2 and set so as to butt against the inner tube 3. . From this state, if compressed air is supplied into the closed space S inside the elastic body 4 through an air valve (not shown) attached to the elastic body 4, the elastic body 4 Since the band tightening except for the part is prevented by the inner pipe 3 from deforming inwardly, it is carved outward and tightly contacts the inner wall of the pipe line 11 to tighten the air plug l inside the pipe line 11. Set to fixed. At the same time, a part of the elastic body 4 that covers the part of the outer tube 2 where the inner tube 3 is not installed (a part of the elastic body 4 located on the outer peripheral side of the pipe 18) is deformed outward. Since it is blocked by the band 5, it swells inward to hold the vibrator 18 and connect the hose 12 to the air plug 1.
