PURPOSE: A connection method is provided to ease assembling drainage line pipe using semi-permanently, preventing a leakage of drainage. CONSTITUTION: An input space of cement mortar is constituted as a connection space each other by forming a welding point(4) according to the length of spirally wound a corrugated support stand(5) by curving an outer wall of drainage line pipes(A,B). A construction for preventing a leakage is conveniently performed by reclaiming soil dug around after curing for a specific time by filling cement mortar into inlets(3,7). To provide an active endurance lengthwise, the construction is improved by forming the input space with the welding point and the corrugated support stand(5) formed as a recessed part curving the outer wall, and also improves the leakage to an assembly part for connecting drainage line pipes(A,B) of different standards.
