PURPOSE: A structure for connecting a water pipe is provided to stably maintain sealing properties against an external force or bending deflection towards a longitudinal direction of the pipe or a diameter direction. CONSTITUTION: A structure for connecting a water pipe comprises a pipe type packing(30), a flange connection pipe(40), a first ring type packing(50), a second ring type packing(60), a third ring type packing(70), a connection member, and a protective cover(90). The outer circumference of the pipe type packing is inclined in a constant angle for gradually enlarging a thickness from the inner outer circumference of each water pipe(10,20) to the end portion in a longitudinal direction. The flange connection pipe is shorter than the pipe type packing and the internal diameter is larger than the outer circumference of each water pipe. A connection piece(91) of the protective cover is coupled with a bolt(910) and a nut(911).
