Abstract | The invention discloses a dual-shield TBM (tunnel boring machine) combined lining support structure and a construction method thereof. The dual-shield TBM combined lining support structure comprises segments, a mold bag, pads, constant loads, surrounding rock, anchor cables/bolts, mold bag grouting holes, constant load and anchor cable/bolt mounting holes, a mold bag groove, pad grooves, and padcenter holes. The mold bag that a flexible foldable chamber member is fixed outside the segments before mounting of the segments and is communicated with the segments via the mold bag grouting holes for the purpose of grouting; the constant loads are mounted at one ends of outer heads of the anchor cables/bolts and are used for keeping constant loading for the anchor cables/bolts. The constructionmethod includes: treating the segments, and mounting the mold bag, the anchor cables/bolts and the constant loads. The dual-shield TBM combined lining support structure and the construction method thereof have the advantages t |
