INVERSION METHOD FOR LINING MATERIAL

摘要

PURPOSE: A pipe lining material inversion method is provided to turn over a pipe lining material by using an outer liner and insert it into a pipe using small reverse pressure. CONSTITUTION: A pipe lining material inversion method is as follows. A pipe lining material(200) is accepted in a containing compartment(110) of square pillar shape. The leading end of the pipe lining material is connected to an inversion nozzle(120) combined in the pipe lining material outlet of the containing compartment. A rear end of the outside liner is airtightly combined in the inversion nozzle to cover the pipe lining material. The pipe lining material is inversed toward lead-in part through the extra length of the outside liner. The reverse pressure is added in the pipe lining material flowed in to the conduit line to reverse the pipe lining material.
