Abstract

476,680. Lining conduits &c. TOWNLEY, J. C. May 11, 1936, No. 13339. [Class 33] [Also in Group XXI] For lining conduits, sewers, pipes, &c., preformed sections are mounted within the structure with their edges spaced from one another longitudinally and transversely, the spaces are then filled in with material which extends to the surface of the structure and bonds the sections together and the cavities behind the sections are then filled in. In lining an egg-shaped sewer, lower sections 12 are first placed and upper sections 11 supported therefrom by telescopic struts, spaces 13 being left between adjacent longitudinal and circumferential edges, the inner sides 11a, 12a of which are bevelled. Reinforcements 14a, 15a of the sections extend into the spaces 13 and are connected by links 17. Regrading may be effected by supporting the lower sections 12 on saddles 16 of wood, brick, concrete, metal, &c., hollowed &c. for the flow of liquids. Bonding material is then applied, preferably by a cement gun, to key the sections together and to extend to the inner wall 10a of the sewer. The cavities behind the sections are then filled by forcing cementitious material 19 through pipes 20; adjacent cavities may be connected by pipes or ducts to relieve back pressure. More than two sections may be used, and if they are not reinforced, their edges are shaped or provided with metallic &c. projections to provide secure bonding.
