作業を実施していた。2. Description of the Related Art A gas pipe that has been set up in the water draining section is exposed to a very corrosive environment due to repeated dryness and wetness due to intermittent use of water in a sink and battery action of dissimilar metals. Therefore, it is necessary to replace the old pipe with the new pipe for repair after the operating time reaches a certain level.
When such a pipe needs to be repaired, first, the drainage pipe under the sink is separated from the water source side pipe, and the movable sink is temporarily removed. After replacing the old and new, after relocating the sink to the original position, the drainage pipe was reconnected and restored.

られている。In the above-described first embodiment, the unfixed gas pipe fixing portion 2a is attached to the upper end of the gas pipe 1 to form the upper end portion 1a, and the male screw joint and the flanged nut-like fixing metal fitting are provided. 9 and the gas cock 7, but in the third embodiment, the gas pipe fixing portion 2a has a gas pipe 1 as shown in FIG.
A male threaded joint that is attached to the upper end and constitutes the upper end portion 1a, and a lower portion of the male threaded joint that is externally fitted together with the washer 11 under the drainer plate 2 and screwed. It consists of a combination of an upward pressing nut 10 to be fastened together and a nipple 12 on the upper side of the draining plate 2 with the gas cock 7 connected to the upper part. In the third embodiment, first, similarly to the first embodiment, the cutting line A using the hole saw 13 for the gas pipe fixing portion 2a (see FIG. 6).
By forming the first perforated portion 5A by performing the perforation (see (a)), the perforated portion 5 having a larger diameter than the upper end portion 1a is provided. By the way, this first perforation is provided by the washer 1
When the washer 11 is reached, the hole washer 13 will idle due to the presence of the non-fixed washer 11. Therefore, the first perforation is temporarily stopped up to the location where the washer 11 is present, the central portion of the draining plate 2 separated by the first perforation is removed, and the downward pressing nut 14 is attached to the removed portion. After the washer 11 is fixed by being screwed and fastened as shown in FIG. 6 (b), a second cutting line B having a diameter larger than the cutting line A (see FIG. 6 (b)) is formed. By forming the perforated portion 5B, the gas pipe fixing portion 2a
The central part of is separated from the main body of the draining plate 2. The subsequent operating procedure is the same as in the first embodiment. The hole saw 13 has a blade body 13
Guide cylinder 13 for centering at the time of drilling at a position preceding a.
Although b is provided, a lower diameter reducing portion 15 is provided on the inner peripheral surface of the male threaded joint as in the third embodiment (see FIG. 6A).
If the reduced diameter portion 15 exists, the guide cylindrical body 13b cannot guide the portion after the reduced diameter portion 15 exists. As a hole saw 13 capable of coping with such a problem, a guide cylindrical body 13b having a compression coil spring 13d which is compressed and deformed so that it can be guided after the existing position is considered (see FIG. 6B). Has been.
