Patent ID: 7686054

Claim:
An apparatus for everting and inserting, via a vertical manhole, a pipe-lining material impregnated with a curable resin for use in rehabilitating an underground pipeline that extends in a direction inclined relative to the vertical manhole, the apparatus comprising: a storage container storing the pipe-lining material in an un-everted state; an everting nozzle for everting the pipe-lining material, the everting nozzle having a nozzle opening that confronts an opening of the pipeline to be rehabilitated during use of the apparatus so that when the pipe-lining material is drawn from the storage container and is brought un-everted up to the everting nozzle and attached to the nozzle opening thereof and fluid pressure is supplied inside of the pipe-lining material, the pipe-lining material is everted and inserted into the pipeline to be rehabilitated in a pipe-extending direction thereof; and a mounting pipe removably connected to the storage container and disposed between the everting nozzle and the storage container, the mounting pipe having an upper portion with an open end through which the pipe-lining material is inserted when brought un-everted up to the everting nozzle and attached to the nozzle opening thereof, a side portion with a duct through which a heating medium supply hose is introduced into the everted pipe-lining material for supplying a heating medium into the everted pipe-lining material after the mounting pipe is disconnected from the storage container following completion of the eversion and insertion of the pipe-lining material into the pipeline to be rehabilitated, and a window via which the introduction of the heating medium supply hose into the everted pipe-lining material through the duct of the mounting pipe is observed.
