<p>PURPOSE:To surely seal the communication part of a lining pipe and a branched pipe by providing a pair of cylindrical holding members which hold two liquid of expandable sealing material respectively and are regulated to the rate of the cross-sectional area correspondent to the mixing ratio of the respective liquids and a pair of supply tubes whose respective end parts are connected to the respective holding members. CONSTITUTION:When both liquid being a curing component of the expandable sealing material and liquid being an uncuring component are simultaneously supplied at equal amount into the respective supply tubes 32 and 33, the curing component and the uncuring component of equal amount are introduced into a mixing pipe 35 through a check valve 34. While these two liquids are passed through the mixing pipe 35, both are mixed. Thereby while the sealing material starts foaming, it is passed through the mixed pipe 35. Furthermore the mixed expandable sealing material is introduced into the mixing pipe 25 of a stop cock 20 from a flexible joint 40 and mixed while it is passed through the mixing pipe 25. Thereafter the sealing material is packed into the end part between the stop cock 20 and the lining pipe.</p> |
