摘要
Method of construction of a vault, in which at least two half-shells (1-8; 60) are brought to bear against one another by means of at least two bearing pieces (30, 50; 70) which are mated and, each half-shell (1-8; 60) comprising an upper edge (21; 61) and a bottom lip (22); each bearing piece (30, 50; 70) is fixed removably to a half-shell (1-8; 60), the two half-shells (1-8; 60) are brought to bear against one another temporarily via their bearing piece (30, 50; 70) without their bottom lips (22) being brought to bear against one another, a keystone-forming material is cast between said upper edges (21; 61), on the bottom (14) constituted by the lips (22), so as to bring about continuous transverse joining together of the half-shells (1-8; 60), and then the bearing pieces (30, 50; 70) are removed so as to effect load transfer from the bearing pieces (30, 50; 70) to the half-shells (1-8; 60). The invention is suitable for the construction of a passage under an embankment.
