PROBLEM TO BE SOLVED: To simply, rapidly and safely carry out, for example, a piping such as a drain pipe of building. SOLUTION: In the piping method, after the coupling pipe 5 is fixed to a predetermined position, a concrete is placed to form plate parts made of concrete such as a floor 4 and a wall 34. Therefore, one end of a lengthy pipe body 1 is inserted into at least one spigot port 7 of the coupling pipe 5 from the spigot port 7 direction while inclining it and the other end (lower end 2a) of the pipe body 1 is subsequently connected to the opposed coupling pipe 5.
