PURPOSE: A method and structure for connecting drainpipes by using a clip flange provided to improve watertightness and to firmly connect the drainpipes. CONSTITUTION: In a structure for connecting drainpipes, a plurality of bolt holes(12) are formed at the circumference of drainpipes(10). Flanges(20) are melted at one end of the drainpipes. A heating unit has a heating element(30) inserted between the flanges, and a terminal wire(34) supplying electricity to the heating element. Clips(40) pierce through the bolt holes, and connect the drainpipes.
