PURPOSE:To prevent groundwater and sediment from entering through the joint of a collecting sewer. CONSTITUTION:A lining material is composed of a flange 8 and a felt tube 9, which contain a setting resin, and a heat resistant film tube 10. The lining material is inserted into an inversion guide pipe 2 of a packer 1; the flange 8 of the lining material is attached on the surface of the packer 1. The packer 1 is moved to the joint 22 of the a collecting sewer 21. Compressed air is introduced into the packer 1 to expand it, and the flange 8 is fixed to the joint 22. Compressed air is introduced into the inversion guide pipe 2; the lining material, which is inverted, is inserted into the collecting sewer 21. The setting resin in the flange 8 and the felt tube 9 is cured, and the joint 22 of the collecting sewer 21 is coated with a synthetic resin. |
