  • Voussoir for a lining, and method for constructing the lining
    Patent number: 3961411
    Abstract: Method for constructing a bore lining comprising pre-assembling in the factory voussoirs into a panel in a jig having the required outside dimensions for the panel by means of a connecting material which fills the gaps between the voussoirs. Each panel has at least two voussoirs which are juxtaposed in at least one of circumferential and axial directions of the panel. The pre-assembled panels are then transferred to the construction site and laid directly in the bore so as to form the lining.A voussoir for the panel and a jig for assembling the voussoirs into a panel are described.
