PROBLEM TO BE SOLVED: To provide a method for jointing an olefin resin pipe represented by a polyethylene pipe that is difficult to joint by an adhesive.SOLUTION: An enlarged diameter section 5 having an inside diameter of the identical dimension to an outside diameter of an insertion port 3 is formed at an end of one resin pipe fitted with an insertion port 3 formed at an end of the other resin pipe 1, so as to form a receiving port 4. Annular grooves 7, 9 opposed to each other are provided on an outer periphery of the insertion port 3 and an inner periphery of the receiving port 4. After a room-temperature hardening type resin base filler having viscosity and fluidity is injected to the annular grooves 7, 9, while the insertion port 3 is fitted with the receiving port 4 and both of the resin pipes 1 are held at a position at which the annular grooves 7, 9 are opposed to each other, a filler filled in the annular grooves 7, 9 opposed to each other is naturally hardened into a hardened filler 22 filled in the annular grooves 7, 9 as a time has elapsed. A tensile load acting in an axial direction of both of the resin pipes 1 is endured by an action for blocking detachment of the hardened filler 22. |
