正在建设的港珠澳大桥连接珠海、澳门和香港,是迄今为止世界上最长,施工难度最大的跨海大桥。工程中最大的挑战就是在茫茫大海中央修建一条5.6公里的海底隧道,长度、规模、施工工艺都是我国首次尝试,因此一些经验丰富的老技师都面临着全新的挑战,钳工管延安就是其中的一个。因为要避让空中航线和海面货轮,大桥两头是桥面,中间用一条5.6公里的海底隧道连接。考虑到地质条件和生态保护,港珠澳大桥海底隧道并没有采
The Hong Kong-Zhuhai-Macau Bridge under construction, connecting Zhuhai, Macau and Hong Kong, is by far the longest and hardest-constructed cross-sea bridge in the world. The biggest challenge in the project is to construct a 5.6-kilometer subsea tunnel in the middle of the vast sea. The length, scale and construction technology are the first attempts in our country. Therefore, some veteran experienced technicians are facing new challenges. One. Because of the avoidance of air routes and sea freighters, the two ends of the bridge are bridge decks, with a 5.6 km undersea tunnel in the middle. Considering the geological conditions and ecological protection, the Harbor Crossing of Hong Kong-Zhuhai-Macau Bridge has not been adopted
