The article describes the design and construction of the tunnel lining system in the Budapest metro. The lining consists of unconnected reinforced concrete hinged segments in which each ring consists of a bottom segment, six side segments of uniform size and one key segment consisting of three pieces. The lining, made up of ten segments of three basic sizes, has an outside diameter of 5.5 M and a wall thickness of 200 mm. Each 1.0 M wide concrete ring has a volume of 3.46 cu M and a weight of 8.68 t. A feature of the lining structure are the hinges where the segments support each other. The hinge design allows movement of the segments to minimise the bending moment. The lining system overcomes waterproofing problems by a combination of concrete mix technology and a bituminous coating with caulking between segments. Details are given of construction techniques used for the tunnel lining system.
