Abstract:
A high-strength confined concrete support system for an underground tunnel. The support system includes multiple confined concrete arches, bolts and cables, and a prestressed steel strand backfilling system. The confined concrete arches all support the surrounding rock of the tunnel and are sequentially arranged along the tunnel. Every two adjacent confined concrete arches are connected by a longitudinal connection structure. The support system is provided with a plurality of layers of steel bar meshes on the surrounding rock side and the tunnel side, and shotcrete layers are sprayed on the support system and the steel bar meshes. The prestressed steel strand backfilling system comprises a prestressed steel strand system and a filling material. The filling material fills the space between each confined concrete arch and the surrounding rock to equalize a load on the confined concrete arch and generate prestress.

Claim (Index 1):
A high-strength confined concrete support system for an underground tunnel, comprising: multiple confined concrete arches, bolts and cables, and a prestressed steel strand backfilling system, wherein the confined concrete arches form an internal bearing layer of the support system; the bolts and the cables form an external bearing layer of the support system; the bolts and the cables are embedded into the surrounding rock; and a filling material is injected between the arches and the surrounding rock to form an intermediate bearing structure layer;\n the confined concrete arches all support the surrounding rock of the tunnel and are sequentially arranged along the tunnel; every two adjacent confined concrete arches are connected by a longitudinal connection structure; the support system is provided with a plurality of layers of steel bar meshes on the surrounding rock side and the tunnel side, and shotcrete layers are sprayed on the support system and the steel bar meshes; the prestressed steel strand backfilling system comprises a prestressed steel strand system and a filling material; the prestressed steel strand system refers to that steel strands for connecting the arches with the bolts and the cables sequentially run through arch cable-passing holes and tray cable-passing holes to form a continuous grid between outer edges of the arches and the surface of the surrounding rock, thereby connecting the arches with the bolts and the cables; and the filling material fills space between each confined concrete arch and the surrounding rock to equalize a load on the confined concrete arch and generate a prestress.
