Title:

PIPE LINING MATERIAL-REVERSELY TURNED NOZZLE AND PIPE LINING CONSTRUCTION METHOD

Document Type and Number:

Japanese Patent JP2001138399

Kind Code:

A

Abstract:

To provide pipe lining material-reversely turned nozzle wherein an operator can come in or out from a man-hole during lining operation.

In a pipe lining material-reversely turned nozzle 31 equipped with a guide tube-fixing end 32 for fixing one end of a guide tube 20, and a pipe lining material-fixing end 33 for fixing one end wherein a nonreversely turned pipe lining material 10 passing through inside the guide tube 20 is folded back, a caliber of the guide tube-fixing end 32 is set less than a caliber of the pipe lining material-fixing end 33. A guide tube 20 of a less caliber than that of pipeline 50 (or a pipe lining material 10) can be used, and a necessary and sufficient clearance is formed between the small caliber guide tube 20 and a man-hole 51. Therefore an operator freely comes in and out from the man-hole 51 during lining operation from that clearance, and a state of the lining or the like can be examined and confirmed.
