<p>PURPOSE:To realize the effective pipe and processing by charging the inside of a conduit with a charging material through an opening drilled by using a drilling device and hardening the charging material, then cutting the conduit, and closing the pipe end formed through the cut, in a regular manner by using a coupling member, etc. CONSTITUTION:A saddle-shaped installation part 2 is set on a conduit 1 and installed on the conduit 1 through the tightening by a belt 2b, and then a cylindrical part 3 is revolved, and the drilling by a hole saw 3b is realized, and an opened port 1a is formed on the conduit 1. A tube 6 is connected at the basic end part of the cylindrical part 3, and after a valve 7 is set to an opened cock state, a charging material and the two-liquid type silicone foaming material are mixed through the tube 6, and then sent into the through hole 3a of the cylindrical part 3, and further sent into the conduit 1 in front of the through hole 3a through the opening 1a, and then a charging part B for closing the pipe end side is formed in the conduit 1, by hardening the charging material, and then the conduit 1 is cut at the charging part B or at the place on the downstream side of the charging part B, and the pipe end formed by the cut is closed in a regular manner by a coupling member.</p> |
