Introduction of Construction Process in Shenjiamen Immerse Tube Tunnel and Problem Analysis of Grouting
Abstract:
The construction method for immerse tube tunnelling varies significantly in sites with different hydrogeological conditions. Using the construction process of the undersea immerse tunnel at Shenjiamen harbour, Zhoushan city, Zhejiang Province as an example, the overall construction process of undocking, float transporting, immerse positioning, locking, grouting and backfilling were introduced in this study, with possible problems at each stage listed in details. The problems occurred when grouting Tube E1, E2 and E3 (floating or settling) and relevant solutions were concluded and the related possible causes were analysed.
