The present invention relates to: a manufacturing method of a multipipe which can be used as a pipeline facility including a drainpipe, a sewer pipe, a water pipe, a water supply, and a rainwater pipe; and the multipipe manufactured by the method. More specifically the present invention relates to: a manufacturing method of a water barrier wall multipipe which prevents the transformation including the twisting and collapsing of the pipe by independently inserting a block type water barrier reinforcing member through a hollow hole of a profile, and prevents the deformation including water leakage, strength decrease, and breakage of the pipe after installing the pipe; and the water barrier wall multipipe. |
