An insertion pipe closely accommodated at one end of the receiving pipe,
A flange coupled to an outside of the insertion pipe and fixed to the one end of the receiving pipe by a fixing hardware,
Water milling provided at a position where the receiving pipe and the flange are in contact with each other to ensure watertightness,
An induction processing groove located at a lower end of the water mill and formed at a position where the insertion pipe and the flange are in contact with each other so as to form a vortex,
And a coupling device coupled to the receiving pipe and the insertion pipe outside to couple the insertion pipe into the receiving pipe with hydraulic pressure and air pressure.
8. The method of claim 7,
Wherein the receiving pipe has a joining portion formed in a slanting line so that the outer circumferential surface of the insertion pipe can be brought into close contact with the inside of the receiving pipe,
An accommodating portion formed to have a larger diameter than the joint portion and surrounding one end of the insertion pipe;
An engaging plate extending outward from an end of the receiving portion and coupled by the fixed metal member to the flange,
And a measuring unit provided in the receiving part and measuring leakage and pressure by measuring an air pressure and a water pressure of a measuring space formed when the receiving pipe and the inserting pipe are engaged.
9. The method of claim 8,
Wherein the insertion pipe includes an insertion portion inserted into the inside of the accommodation portion,
An engaging portion provided at one end of the insertion portion and formed in a slanting line so as to be brought into close contact with the abutting portion,
A caulking material provided as a ring outside the engaging portion to enhance airtightness between the engaging portion and the abutting portion,
And a protrusion protruding to the inside of the insertion pipe to form the induction processing groove at a position where the insertion portion contacts the flange.
10. The method of claim 9,
Wherein the inserting pipe further comprises a fixing body provided on a rear face of the caulking material to prevent the caulking material from moving between the inserting portion and the inserting portion by water pressure. Device.
8. The method of claim 7,
Wherein the water milling has a body capable of securing fluidity and improving watertightness between the receiving pipe and the flange due to elasticity,
A through hole through which at least one of the receiving pipe and the inserting pipe is coupled to the body,
And a joint hole formed to pierce from the inside to the outside of the body and formed on the inner side of the body by the vortex of the atmospheric pressure and the water pressure generated in the induction treatment groove and to be closely attached to the receiving pipe and the flange Wherein the watertightly inductive coupling device of the insertion type flange pipe is characterized in that the watertightly inductive coupling device of the insertion type flange pipe.
9. The method of claim 8,
Wherein the coupling device comprises a guide rod fixed to the flange by one end of the flange after being passed through the flange and the other end extending to the receiving pipe,
A pneumatic-pressure cylinder coupled to the other end of the guide rod and adapted to move the flange, which is engaged with one end of the guide rod by hydraulic pressure and pneumatic pressure,
And a fixing plate coupled to an outer surface of the pneumo-hydraulic cylinder and fixed to the measuring unit.
