  Ideas on Novel Factory Flowline and Element of Negative Buoyancy for Immersed

  The Shenzhen Yanjiang Highway Qianhai-Nanping Transit Project is an EPC contract that covers feasibility study, conceptual design, pre-design, construction design, procurements of facilities and equipment, and constructions. The project is located in the centre area of the Qianhai and Bao'an of Shenzhen city, on the east coastline of the Pearl River. The immersed tunnel that is part of the Yanjiang Highway is 2.31 km long; the design speed is 100 km/h, eight-lanes double ways. The main challenges are the very tight schedule and relatively confined land space for tunnel element prefabrication. This paper proposed a novel factory flowline to prefabricate concrete tunnel element with three segments based on the proven technique of the Island and Tunnel project of Hong Kong-Zhuhai-Macao Bridge. Quantitatively analysis shows that the method shortens the prefabrication period, occupies less land and saves work efforts as compared to the conventional. Further, tunnel elements designed and built with negative buoyancy will have unique benefits.
