在港珠澳大桥之前,中国工程师没有做过外海沉管隧道。我们就是要用中国人的勇气和智慧,去攻克世界级难题,创造“唯一”。——港珠澳大桥岛隧工程项目总经理、总工程师林鸣10月8日,港珠澳大桥岛隧工程E33沉管安装到位。这项工程的基本概念是,在珠江口构筑两个人工岛,然后在这两个人工岛之间,用33个巨大的混凝土管子,次第对接起来形成一个近6公里的海底隧道。两个人工岛分别向东西两个方向通过桥梁连接陆地。港珠澳大桥海底隧道总长5664米,是世界最长公路沉管隧道及唯一深埋沉管隧道,被誉为交通工程的“珠穆朗玛峰”。中国交建港珠澳大桥岛隧项目团队自主创新,攻坚克难,经过近两年的筹划,一年的科研,半年多的施工准备,于10月8日完成了首节曲线段沉管E33的安装,成功攻克世界级工程难题。这也是全世界首个工厂化预制的曲线段沉管。本期“关注”走进港珠澳大桥岛隧工程项目部,解密首节曲线段沉管E33安装前后的故事,展示中国工程建设者的风采。
Before the Hong Kong-Zhuhai-Macao Bridge, Chinese engineers had not done any immersion in the sea tunnel. We just want to use Chinese courage and wisdom to overcome world-class problems and create “the only one.” - Hong Kong-Zhuhai-Zhuhai Bridge Project General Manager, Chief Engineer Lin Ming On October 8, Hong Kong-Zhuhai-Macao Bridge Project E33 immersed pipe installed in place. The basic concept behind the project is to construct two artificial islands at the mouth of the Pearl River and then use 33 huge concrete pipes between the two artificial islands to make up for a submarine tunnel nearly 6 kilometers in length. The two artificial islands are respectively connected to the land by bridges in both east and west directions. The total length of the undersea tunnel of Hong Kong-Zhuhai-Macao Bridge is 5664 meters. It is the longest road immersed tunnel in the world and the only deep immersed tunnel. It is also known as the “Everest” of traffic engineering. After more than two years of planning, one year’s research and more than six months of construction preparation, China Jiaosho Hong Kong-Zhuhai-Zhuhai-Zhuhai-Zhuhai Bridge Project completed the first curve curve E33 Installation, successfully overcome the world-class engineering problems. This is also the world’s first factory prefabricated curved segment immersed tube. This issue “concern ” into the Hong Kong-Zhuhai-Macao Bridge Project Department, to decrypt the first section of the curve before and after the installation of tube E33 story to show the style of Chinese construction builders.
