日前,港珠澳大桥桥梁工程建设取得新突破。继九洲航道桥“预制承台”钢管桩插打之后,主桥墩“钻孔桩”顺利开钻,采用国内钻孔深度最大的钻机作业。同时,全桥首个永久混凝土结构——首块“预制桥面板”也完成浇筑施工,相关钢筋和混凝土工艺的120年寿命技术在国内尚属首次;目前已全面展开2500多块桥面板预制工作,以确保大桥工程各项目标建设的如期完成。
Recently, the Hong Kong-Zhuhai-Macao Bridge construction achieved a new breakthrough. Following the Jiuzhou Channel Bridge “prefabricated platform ” after the steel pipe plug, the main pier “bored pile ” smooth drilling, using the largest drilling depth drilling operation. At the same time, the first permanent concrete structure of the whole bridge - the first piece of “prefabricated bridge deck” also completed the pouring construction, and the 120-year life-span technology of related reinforced and concrete technologies is the first time in China; at present, more than 2,500 bridge decks Prefabricated work to ensure that the construction of the bridge project objectives completed on schedule.
