Title:
LINING METHOD OF PIPELINE
Document Type and Number:
Japanese Patent JP3216505
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To securely harden resin liquid infiltrated in a lining material by a method wherein drain is produced with a water pressing member to the terminal of the lining material and then discharged so as to transmit the gas under heat and pressure without being shut off by the drain even at the recessed part of a pipeline to the lining material through heating liquid.
SOLUTION: A lining material 4 is inserted in a pipeline 1 so as to urge the lining material 4 to the inner surface of the pipeline 1 by feeding pressure fluid in the lining material 4. Further, gas under heat and pressure containing pressurized steam is fed from one end of the lining material 4 and, at the same time, a flexible water pressing member 9 is reciprocatingly moved over the whole length of the lining material 4 so as to discharge the liquid gathered to the terminal of the lining material 4 from the terminal.
