Title:
START LINER WITH COLLAR FOR BRANCH TUBE AND TUBE LINING CONSTRUCTION METHOD
Document Type and Number:
Japanese Patent JP2702099
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To integrate a connection part by preventing shortage in strength of a lining material owing to inferiority in hardening though ground-water permeates by a method wherein respective one ends of a start liner tube of almost the same diameter as a caliber of a branch tube and a pressure bag connection tube are fitted to a collar.
SOLUTION: When a main tube 10 is ended to be lined, a branch tube 11 is then lined by using a branch tube lining material 25. The branch tube lining material 25 is inserted by reversing toward the main tube 10 from a ground side by fluid pressure inside a start liner tube 3 of a start liner with a collar for branch tube an upper part of which is fixed by hauling. At that time, though ground-water is barriered by the start liner tube 3, a thermosetting resin impregnated with the branch lining material 25 does not come in direct contact with the ground-water. Thereby, the setting resin is prevented from being deteriorated in hardening, and strength required for each lining material can be secured.
