Research on Water Environment Protection Technology During the Construction Period of Bridges in Shenzhen-Zhongshan Link

During the construction period of sea-crossing bridge, pile foundation and other operations are easy to cause marine water environment pollution. In order enhance green development level cross-river (sea) channel project, this paper selects Shenzhen-Zhongshan Link, a typical cross-sea traffic cluster as research object. And introduces environmental protection technologies such bored with steel casing, cofferdam formed by locking pipe pile, geotech-bag, whole trestle across sea. The variation characteristics suspended solids, oil, inorganic nitrogen, phosphorus heavy metal concentrations respect time space in sea area bridge project were systematically analyzed, explore influence on quality area. Further verify application effect technologies, provide reference for similar future.
