Description of the Related Art Conventionally, ducts using ductile cast iron pipes and the like have been frequently used to guide clean water taken in on the upstream side to utilization facilities on the downstream side. If foreign matter such as mud enters the pipeline, the foreign matter is transported together with the water to the downstream usage facility, which becomes an obstacle when using water supply at the usage facility.

Is done. Reference numeral 9 denotes a branch pipe, which is formed integrally with the main pipe 6, and has a spiral part 10 formed from the bottom to the top along substantially half the circumference of the main pipe 1, and a top of the main pipe 1. And a branch portion 11 extending upward from the branch portion, and a flange 12 for attaching a fire hydrant is provided at a tip of the branch portion 11. The main pipe 6 at the portion where the branch pipe 9 is formed
An opening 13 communicating with the branch pipe 9 is formed at the bottom of the pipe, and foreign matter flowing along the bottom of the main pipe 6 is prevented from flowing through the opening 13.

There is a problem that the formed air vent hole 14 cannot be made so large, which is not always satisfactory for obtaining sufficient air vent performance. That is, in the conventional spiral T-tube 4 for discharging foreign matter, a conventional T-tube in which a branch pipe branches directly from the top of the pipe body.
There is a problem that the air release performance is only about 1/30. For this reason, when the end of the branch portion 11 is opened to forcibly drain the water through the air vent hole 14, most of the air in the pipe can be forcibly exhausted with that,
In the case where only the air that naturally passes through the air vent hole 14 is stored in the branch portion 11 without opening the end of the branch portion 11,
It is difficult for the air in the main pipe 1 to escape, and air bubbles flowing from the upstream side in the main pipe 1 will flow away to the downstream side.
