<p>PROBLEM TO BE SOLVED: To provide a connecting structure, of an underground buried pipe to a connection part, by which the underground buried pipe can be connected to the connection part easily and quickly, which can be used satisfactorily for a long period and which is low-cost. SOLUTION: In the connecting structure of an underground buried pipe to a connection part, an underground buried pipe 2 is connected to the connection part 1 at a handhole, a manhole or the like. In the connecting structure, an outside coupling member 3 which is externally fitted freely and an inside coupling member 4 which is internally fitted freely are installed at the underground buried pipe 2. In a state that the tip of the underground buried pipe 2 to which the outside coupling member 3 is externally fitted is inserted into a through hole 1A formed in the connection part 1, the outside coupling member 3 is moved to the tip side of the underground buried pipe 2. The inside coupling member 4 is internally fitted to the tip of the underground buried pipe 2. When the outside coupling member 3 and the inside coupling member 4 are moved to the side of the through hole 1A, pressure parts 3B, 4B by which an adhesive S which is coated on the outer face at least of the underground buried pipe 2 is moved to the side of the through hole 1A in the connection part 1 are provided at both coupling members 3, 4.</p> |
