Abstract:
The south section of No. 11 Line of Shanghai rail transit works is a singletube doubletrack tunnel bored by 11.58 m slurry shield. Prefabricated concrete separation wall is assembled within the Metro tunnel. To this end, a separation wall assembling machine is developed on basis of the construction schedule and the working environment, so as to improve the assembly efficiency and the assembly quality. In the paper, the key technologies for the assembly of the separation wall, including the prefabricated component hoisting and assembling technology, the temporary supporting technology and the dowel steel installation technology, are presented.
Key words: No. 11 Line of Shanghai Rail Transit Work, singletube tunnel containing double tracks, Metro tunnel, separation wall, prefabricated component, hoisting
