PURPOSE: An expanded pipe and a structure of a joint thereof are provided to prevent the movement of the pipe because an expanded part and a socket part are simultaneously locked in both sides of the joint. CONSTITUTION: An expanded pipe and a structure of a joint thereof comprise a socket part(300), an expanded part(200), and multiple joints(100). A protruding sill(310) is formed in the socket part at one end of a pipe. An inclined portion(210) is formed in the expanded part at the other end of the pipe and is expanded to fit the socket part. The multiple joints have a synthetic rubber packing(150), a stopping sill(110), and an inclined stopping sill(120). The multiple joints connect the socket part and the expanded part.
