Title:
SHIELD TUNNEL SEGMENT STRUCTURE AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/170638
Kind Code:
A1
Abstract:
A shield tunnel segment structure and a construction method therefor. The shield tunnel segment structure comprises segment blocks (1, 2, 3, 4) sequentially spliced in the circumferential direction. The segment blocks form closed annular segment structures, and the outer diameters of the annular segment structures adjacent in the axial direction are gradually increased; at least two adjacent segment blocks of the same annular segment structure form an annular inner groove (11, 21), and at least one segment block of the adjacent annular segment structures is provided with an inner convex block (22) matched with the annular inner groove; at least two adjacent segment blocks of the same annular segment structure form an annular outer groove (31, 41), and at least one segment block of the adjacent annular segment structures is provided with an outer convex block matched with the annular outer groove; and the annular outer grooves and the annular inner grooves are arranged in a staggered mode in the circumferential direction. The shield tunnel segment structure and the construction method therefor have the advantages that mounting of segments of tunnels having different diameters can be achieved, and safe transition of the tunnels from one diameter to another diameter can be achieved.
