<p>The disclosure relates to a method of moulding an arcuate tunnel lining segment. A mould (10) has a mould cavity formed by a convexly curved surface (11) terminating in axially extending end faces (12) and bounded by side walls (13). Fastening devices in the form of preformed hoops (15) are mounted in the mould cavity at the ends (12) of the cavity and further fastening devices in the form of sockets (16) are mounted in the cavity on the side walls (13). Preformed arcuate reinforcement for the segment is then located in the mould cavity and connected to the fastening devices to support the reinforcement in the mould and concrete is cast in the mould over the reinforcement and fastening devices to form a reinforced cast concrete segment with casting fastening devices in the circumferential and axially extending edge faces.</p> |
