Hong Kong-Zhuhai-Macao bridge closure can be built with the steel quantity 60 Eiffel | _ Hong Kong-Zhuhai-Macao Bridge news
Now on the Lingdingyang, Qingzhou channel bridge "Chinese knot" shined, river-sea direct link ship channel bridge "Dolphin" lifelike, Jiuzhou channel bridge of "sailing" sail tower stands. Hong Kong-Zhuhai-Macao Bridge is like a rainbow to lay the wave, water dragon, between sea and sky in the clouds, forming a beautiful landscape. New Express Reporter Ning Biao/photo United Kingdom newspaper the guardian as one of the "seven wonders of the modern world", one of the Hong Kong-Zhuhai-Macao Bridge yesterday to usher in a historic moment, yesterday at 10 o'clock in the morning, about 23 km in length declared a success of Hong Kong-Zhuhai-Macao Bridge bridge closure. The successful closure of the bridge, bridge traffic conditions that goal by the end of next year has laid a solid foundation.
According to reports, the Hong Kong-Zhuhai-Macao Bridge, when completed will be the world's longest Cross-Sea Bridge. By then, the Hong Kong and Zhuhai, transportation time will be much shorter driving time from Hong Kong to Zhuhai will be reduced from the current 3 hours 20-30 minutes. With the opening of the Hong Kong-Zhuhai-Macao Bridge, docking on land from Zhuhai, Hong Kong and Macao for the first time, it will greatly shorten the distance between Hong Kong-Zhuhai-Macao.

港珠澳大桥主体合龙 用钢量可建60座埃菲尔铁塔|港珠澳大桥_新闻资讯
如今的伶仃洋上,青州航道桥“中国结”熠熠生辉,江海直达船航道桥“海豚”塔栩栩如生,九洲航道桥“风帆”塔扬帆矗立。港珠澳大桥似长虹卧波,蛟龙出水,在云卷云舒的海天之间,形成了一道亮丽的风景线。新快报记者 宁彪/摄 被英国《卫报》誉为“现代世界七大奇迹”之一的港珠澳大桥昨日迎来历史性时刻，昨天上午10时许，全长约23公里的港珠澳大桥主体桥梁宣告成功合龙。桥梁的成功合龙，将为明年底大桥具备通车条件这一目标奠定了坚实的基础。
据介绍，港珠澳大桥建成后将成为世界最长的跨海大桥。届时，香港至珠海的交通时间将大大缩短，开车从香港到珠海的时间将由目前的3个多小时缩减为20至30分钟。随着港珠澳大桥的通车，将首次实现珠海、香港和澳门的陆路对接，将极大缩短港珠澳三地间的距离。

为避台风季提前两个月合龙
新快报记者在相关部门了解到，6月28日23时30分，两台桥面吊机将一段长约8.6米的中跨钢箱梁吊入江海直达船航道桥合龙口，这是港珠澳大桥主体桥梁 的最后一段钢箱梁。29日零时45分，吊装顺利完成。29日上午10时，港珠澳大桥管理局朱永灵局长宣布江海直达船航道桥合龙段开焊，这标志着港珠澳大桥 主体桥梁成功合龙。
据了解，港珠澳大桥总长55公里，是连接香港、珠海和澳门的超大型跨海通道，包括海中桥隧主体工程，以及香港、珠海、澳门三地口岸和连接线。其中，主体工程由6.7公里的海底沉管隧道和长达22.9公里的桥梁工程组成，隧道两端建有东、西两个人工岛。
要克服恶劣的外海施工条件，建设一座同时满足内地、香港和澳门三地标准体系，设计使用寿命长达120年的巨大规模跨海通道，港珠澳大桥因此被誉为“现代世界七大奇迹”之一。
港珠澳大桥主体建造工程于2009年12月15日开工建设，经历了7年的建设，大桥主体桥梁终于成功合龙。施工方长大公司港珠澳大桥项目总工陈儒发表示， 为了赶在台风季节到来之前完成合龙，工程师们设法优化技术方案，积极与相关方沟通协作，合理有效调配资源，将原本8月底合龙的计划足足提前了两个月，从而 确保了台风期桥梁施工安全。
用钢量足以建造60座埃菲尔铁塔
据悉，本次合龙的主体桥梁工程包括3座通航孔桥（九洲航道桥、江海直达船航道桥、青州航道桥）及深、浅水区非通航孔桥。深水区非通航孔桥采用110米跨径整幅整墩钢箱连续梁桥，浅水区非通航孔桥采用85米跨径钢混组合梁。
为减小桥梁基础的阻水率，保证珠江口排洪纳潮及航道通畅，港珠澳大桥非通航孔桥采用埋置式承台，将188个桥梁承台埋入深达8-15米的海床面以下，规模庞大，在国内乃至世界范围内尚属首次。
据记者了解，港珠澳大桥主体工程近23公里的桥梁，首次在桥梁工程上部结构大规模采用钢结构，用钢量达40多万吨，足以建造60座埃菲尔铁塔。
记者获悉，港珠澳大桥主体工程非通航孔桥基础均采用大直径钢管复合桩，桥梁墩台、组合梁、钢箱梁、钢塔全部采用陆上预制，海上运输整体吊装。
岛隧工程完成超过80%
港珠澳大桥被业界誉为桥梁界的“珠穆朗玛峰”，并被英媒《卫报》称为“现代世界七大奇迹”之一。据新快报记者了解，目前，大桥主体工程建设各方正夙兴夜寐，全力推进工程建设。
港珠澳大桥桥梁东西两个人工岛目前在进行道路和临建工程施工。作为世界上最长的沉管海底隧道，港珠澳大桥海底隧道长6.7公里，由33节沉管拼接而成，目前完成27节沉放，已建隧道总长4.7公里，超过总长度的80%。
据了解，明年上半年有望完成人工岛和海底隧道的主体工程，随后将进行海底隧道的路面铺装，明年年底完成建筑机电、环境保护、交通监控等附属配套工程并进行联合调试。
