京张高铁土木特大桥空中旋转 看的人不敢眨眼(图)

2017-10-13 08:17:40   东方网

众所周知,中国“基建狂魔”的称号由来已久,中国基建工程的质量和速度也常常受到中外网民的称赞。近日,一段大桥空中旋转完成对接的视频又一次走红网络。

据央视财经10月11日报道,9月17日凌晨5点,京张高铁土木特大桥的两段悬臂梁开始转体。90分钟后,如巨人臂膀的两段悬臂梁在转体31度后,在空中实现了精准对接,顺利跨越铁路大秦线(大同至秦皇岛)。

据报道,土木特大桥全长3503.48米,位于河北省怀来县土木镇和官厅水库之间。该大桥要依次跨越大秦线铁路、铁路京包线、京藏高速公路这三条交通要道。其中,大秦线为大同至秦皇岛的双线电气化铁路,是世界上最繁忙的一条运营专线。

为了尽量减小施工对大秦线的影响,确保铁路运营安全,承建方决定先在铁路旁边平行施工。然后在前浇块段施工完毕之后,通过墩顶预埋的转体装置完成墩顶转体,将桥梁结构转到原来设计的桥位上。

据报道,这样的墩顶转体施工不但保证了跨越铁路的安全性,还显著降低了工程难度和造价。

网友们看到视频后也纷纷赞叹:厉害了,我的国!

网友们还想到了参与工程的施工人员,留言感谢他们的工作。

还有网友脑洞大开,称之为“纪念碑谷现实版”。

中国基建工程在技术先进,令人称赞的同时,为民众生活带来了极大的便利性。相信这些“中国制造”还将继续惊艳世界。
