PURPOSE:To block up a conduit made of poured resin without using an air bag as in the past, by installing bag-shaped porous body at the top end part of a cylindrical body and holding the resin poured into the conduit in the bag- shaped porous body. CONSTITUTION:When the intermediate part of a conduit 1 is cut off, a saddle- shaped installation part 2 is set on the conduit 1 and installed on the conduit 1 through the tightening by a belt 2b, and an opened port 1a is formed on the conduit 1 by a hole saw 3b. 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 resin A is sent into the through hold 3a of the cylindrical part 3. In the process where the resin A is sent into the conduit 1, a bag-shaped porous body 5 installed at the top end part of the cylindrical body 3 fulfills the function of holding the poured resin A, and on the basis of this holding, the trouble that the resin A is washed away by the gas flow in the conduit 1 can be averted. |
