Abstract

1302954 Casting conduit linings CUFFLIN HOLDINGS Ltd 2 June 1971 [5 June 1970] 27363/70 Heading E1S An underground conduit is lined with castable material, e.g. concrete, using an elongate collapsible former 3 positionable to define a tubular space for casting the lining between the former and the conduit wall, by first installing spacing elements 6 to keep the former spaced from the conduit wall, then positioning the former in an initially collapsed state and expanding it and inflating sealing rings 9, 11 attached to its ends 10, 12 to seal off a first tubular casting space, filling the space with the lining material and allowing to set, deflating the sealing rings and collapsing the former, and then moving the former along the conduit to a position where its trailing end 12 is within the end of the cast portion of lining, and expanding the former and inflating the sealing ring 9 at its leading end 10 to define a second tubular casting space, the cycle being repeated until the full length of the conduit is lined. As each casting space is filled with lining material the displaced air must escape, and this step may be performed by drilling one or more pairs of bores 7, 8 into the conduit from ground level and pumping the lining material in through bore(s) 7 whilst air escapes through bore(s) 8; alternatively, one or more pairs of open-ended tubes may extend inside the former between one end and points along its side wall (Fig. 4, not shown); other arrangements of tubes for this purpose are described. The former 3 may be inflatable or may comprise a collapsible assembly of plates.
