The casing pipe has a circular sheath and a cold water junction disposed on an external wall of the circular sheath, and the circular sheath has a circular sheath hole sheathed onto the first pipework, such that the internal wall of the circular sheath is in a close contact with the two first washers and the cold water junction is interconnected with the interior of the first pipework.
