Construction method of tunnel on artificial island and modular tunnel structure
The invention relates to the technical field of island tunnel engineering construction, in particular to a construction method of a tunnel on an artificial island and a modularized tunnel structure.The tunnel structure is prefabricated in a modularized mode, the tunnel structure is prefabricated firstly, the tunnel structure is transported and installed on water, and island wall construction is conducted synchronously in the tunnel structure construction process; and after island wall construction is completed, island body backfilling work is conducted, parallel implementation of multiple procedures is achieved, the construction period is shortened, and meanwhile it is avoided that tunnel foundation trench excavation and backfilling work is repeatedly conducted on the island body. By the adoption of the scheme, supporting, seepage prevention and excavation construction do not need to be conducted on a newly-filled island body, the construction difficulty is small, the construction efficiency is high, and the construction cost is low.
本发明涉及岛隧工程施工技术领域，具体涉及一种人工岛上隧道的施工方法及模块化隧道结构，本发明将隧道结构模块化预制，通过先预制隧道结构，通过水上运输和安装隧道结构，并在施工隧道结构的过程中同步进行岛壁施工，待岛壁施工完成后再进行岛身回填工作，实现多种工序并列实施，利于缩短施工工期，同时也避免了在岛身上重复进行隧道基槽开挖和回填工作。采用上述方案，无需在新填筑的岛身上做支护、防渗、开挖施工，施工难度小，且施工效率高、工程造价低。
