“基建狂魔”又来了!2020年7月1日,由中国中铁设计承建的世界上首座跨度超千米的公铁两用斜拉桥——主跨1092米的沪苏通长江公铁大桥通车运营,这也标志着世界公铁两用斜拉桥主跨将迈入“千米级”时代。看来,我国“基建狂魔”的称号真不是盖的,这座大桥的建成再创多项世界之最!可你知道吗?就在几年前,中国居然使用火箭来造桥,甚至有世界其他23个国家纷纷效仿,一举创造世界桥梁建筑奇迹!下面我们就跟随西瓜视频创作人“工程师徐小刀”,来一起重温下当年那些不可思议吧。

在地处湖北宜昌与恩施交界处的深山峡谷中,那里横跨着一座目前世界上最长的悬索桥——四渡河大桥。桥梁横跨四渡河峡谷,桥面距离谷底将近600米,全长1365米,宽24.5米。这座大桥在中国现代工程当中绝对算是个超级工程,战胜了种种建造困难,充分的体现了中国人民的智慧,让外国人刮目相看。这其中最神奇的莫过于中国在这座桥的修建当中采用了非常特殊的火箭建桥。

从高速路的建设到高铁,从中国村村通上水电,网络覆盖各个角落。不止是建桥,中国的所有制造业都在飞速发展,不久的将来我相信都会站到全球的尖端,这会开创一个新的时代。

抛送导索沟通两岸、牵引架设拽拉钢缆是悬索桥进入上部构造施工的关键环节。唯此,才能架设空中便桥,开辟主缆和桥面施工工作平台。此前,国内外悬索桥施工均采用人工拽拉、船舶运送、直升机牵引等办法输送导索,但四渡河两岸是刀劈斧削、深达500多米的悬崖绝壁,且峡谷中气流变幻无常,传统办法派不上用场。

大桥建设期间,有一次大桥经理生病住院,他从针管的原理中突发奇想:如果用火箭来抛射先导索是否可以呢?于是他查阅了大量资料并找来了导弹专家商议此事后,施工人员先后发射了两枚小型火箭,每一枚火箭带着一千两百米长的工作索,几秒钟就解决了这一难题,这项“黑科技”也算是开起了用火箭造桥的先河。

中国用火箭造桥的成功的消息一经传出,引得美国日本等国家惊讶的同时也纷纷效仿,不得不赞叹中国人民的大智慧,真是想象力的奇迹。现在每当有国内外游客来中国旅游的时候看到如此气势辉煌的四渡河大桥都会对大桥建造过程感到好奇,然后当他们知道了大桥使用火箭来建造的时候惊讶到目瞪口呆。
