Abstract
PURPOSE:To raise the efficiency of construction work by a method in which a two-layered cylindrical water-proof material consisting of an outer layer of water-swelling rubber and an inner layer of thermoplastic synthetic resin is inserted into a manhole and expanded by heating and pressurizing from the inside to closely adhere it to the inner surface of the manhole. CONSTITUTION:A two-layered cylindrical water-proof material 1 consisting of an outer layer 1b of water-swelling rubber and an inner layer 1a of thermoplastic synthetic resin is inserted into a manhole (a) almost concentrically. A cover 2 is provided for the upper end of the material 1. Steam is supplied through a boiler 3, a conduit 4, and the supply port 2a of the cover 2 into the material 1 to heat and pressurize the inside of the material 1. Hereupon, the resin of the inner layer 1a is softened and expanded with the rubber of the outer layer 1b by receiving the pressurizing force, thereby closely adhering to and covering the inside of the manhole (a).
