Title:
マンホール更生工法
Document Type and Number:
Japanese Patent JP5302696
Kind Code:
B2
Abstract:
To line an inner circumferential surface of side walls (1b, 1c) of a manhole (1), a rehabilitating sheet (3, 3A, 3') made of a sheet material resistant to water and corrosion is provided in the form of a bag having a shape corresponding to the inner circumferential surface to be lined. The rehabilitating sheet (3, 3A, 3') is inserted into the manhole (1) to be lined. Block and plate frames (9, 16) are coupled inside the bag of the rehabilitating sheet (3, 3A, 3') to support it so as to have the shape corresponding to the inner circumferential surface to be lined. A gap between the rehabilitating sheet (3, 3A, 3') and the inner circumferential surface of the side walls (1b, 1c) of the manhole is filled with a filler (13), which is then hardened to line the side walls (1b, 1c) of the manhole (1). Pairs of plate frames (16) having different diameters are coupled to each other to provide ring plates (17) having different diameters. The ring plates (17) are stacked one by one from the maximum one to support the rehabilitating sheet (3, 3A, 3') so as to have a shape of the inner circumferential surface of the inclined side wall portion (1b) of the manhole (1).
