The multi-layered hollow tube produced by the post-processing as described above has a groove 710 at a constant depth along the circumference of the double-layered tube on both side end sides of the double-layered tube manufactured by continuous fusion welding of a square pipe having a hollow portion spirally. The filling filler injected into the groove is formed by forming an airtight layer 720 which prevents the hollow portion from being exposed.

Multi-layered hall tube having the configuration as described above can prevent the leakage of sewage by the hollow portion, and by reinforcing the rigidity of the pipe and the connection portion of the pipe can realize a more stable pipe joint.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
