SEWER LINING CONSTRUCTION DEVICE PROVIDED WITH FEED ROLLER, AND LINING APPLICATION METHOD IN SEWER USING THE CONSTRUCTION DEVICE

摘要

To be able to accommodate increasing of size and weight of a spiral lining construction device for strip members used in a sewer having a feed mechanism equipped with a feed roller that abuts against an inner wall/bottom surface of the sewer to give feed force, and to give a large transmission force.SOLUTION: A sewer lining construction device has a joining mechanism part that includes an inner surface roller and an outer surface roller that are mounted on a drive shaft held by a rigid box and are rotated in opposite directions by meshing of gears, and forms a lining pipe by a function of sandwiching and joining the inner surface roller and the outer surface roller to a belt-like member. In the rigid box, a feed roller is disposed on a feed roller drive shaft disposed outside and parallel to the drive shaft of the outer surface roller, and the feed roller drive shaft is driven by meshing with the drive shaft of the outer surface roller.SELECTED DRAWING: Figure 10
