APPARATUS AND CONSTRUCTION METHOD FOR LINKING EXISTING PIPELINE

摘要

PROBLEM TO BE SOLVED: To easily line an existing pipeline with a resin by man power at a low cost without using water pressure or air pressure, even if one end side of the existing pipeline is plugged.

SOLUTION: This apparatus for lining the existing pipeline is constituted of a pig introducing member 1 which is freely attachably and detachably connected to one open end A' of the existing pipeline A and a lining member 2 for lining the inside surface of the pipeline A with a lining liquid B. The member 1 is provided with a connection port 11 to be connected to the end A', an introduction port 12 of the member 2 and a lining liquid feeding port 13 formed between the ports 11 and 12. The member 2 is formed by connecting a lining pig 21 for lining the inside surface of the pipeline A with the liquid B to a lining liquid conveying pig 22 for conveying the liquid B to the inner part of the pipeline A while interposing a flexible connection member 23 between the pigs 21 and 22 and connecting a pushing/pulling operation member 24 to the pig 22.
