Title:
STEEL-CONCRETE COMPOSITE TUNNEL LINING SUPPORT STRUCTURE AND MANUFACTURING AND CONSTRUCTION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/045425
Kind Code:
A1
Abstract:
Disclosed is a steel-concrete composite tunnel lining support structure. The support structure is composed of a curved unit plate member (1) assembled along a tunnel wall circumferential direction and axial direction. The unit plate member (1) has a pair of curved edges (2) and a pair of straight edges (3). Projecting ribs (4) are provided at intervals at an inner wall of the unit plate member (1) in a direction of the straight edges (3). A curvature of the projecting rib (4) is consistent with the curved edges (2). The projecting rib (4) forms a cavity cylinder (5) with the unit plate member (1). A concrete pouring hole (6) is provided at a surface of the projecting rib (4), and a concrete overflow hole (7) is provided at the unit plate member (1) corresponding to the projecting rib (4). The curved edge (2) curved inwards to form an end surface flange (8), and a side edge flange (9) is provided on the straight edge (3). The support structure can immediately bear a pressure load of surrounding rock of a tunnel upper portion and periphery, rapidly and timely supporting a newly excavated hole and preventing the newly excavated hole from collapsing. The support structure usable can be used as a primary lining, and can also be combined with a secondary lining, and can be used to repair and reinforce damaged tunnels. Also disclosed is a method of manufacturing and constructing the tunnel lining support structure.
