Title:
CONSTRUCTION METHOD FOR INNER STRUCTURE OF SINGLE-BORE DOUBLE-TRACK COMPOSITE LINING SHIELD TUNNEL
Document Type and Number:
WIPO Patent Application WO/2018/214737
Kind Code:
A1
Abstract:
The present invention relates to the field of shield tunnel construction, and provides a construction method for the inner structure of a single-bore double-track composite lining shield tunnel. Steps of the method mainly comprises a first stage and a second stage; in the first stage, composite lining construction is conducted on the middle section and/or the rear section of a tunnel synchronously during tunnel boring, and lining is conducted on the tunnel by adopting the order of first lining and then splitting from bottom to top in the composite lining construction; the second stage is a construction stage after the tunnel is bored through. By means of the construction method, construction of the inner lining structure is conducted on the middle section and/or the rear section of a tunnel synchronously during shield tunnel boring, and thus the construction efficiency is improved; moreover, the order of first lining and then splitting from bottom to top is generally adopted in the composite lining construction, and thus, the stability of the interior of the tunnel can be guaranteed, and smooth passing in the construction space is also guaranteed. The present invention has good practicability.
