中国又一工程惊艳世界:长城下有座世界最深高铁站

2017-08-14 15:21:06   海外网

能否保证安全?

△红色管道为求生通道

上图中通体红色的管状廊道,现在是施工通道,未来将形成立体环形救援廊道,乘客在车站的任何位置都可以在50米之内到达求生通道。

地下如何换气?

△4根竖直管道为通风井

上图可以看出,车站第三层中央有4个通风井,新鲜空气可以从这里进去。

△通风管道

施工中的通风是通过斜井口的4台风机吹进掌子面的。上图中隧道顶部橘色的大型管道就是通风管道。

地震等灾害怎么办?

专家告诉记者,整个隧道按照高级别抗震要求设计,抵抗烈度为8度的地震是没问题的。

世界之最的背后有多少挑战与艰辛

掌子面比篮球场大

从二号斜井一路下行,来到一处宽阔的掌子面。这是国内单拱跨度最大的一段暗挖隧道,跨度32.7m,高度19.5米,整个面积比一个标准篮球场还大。施工跨度大再加上隧道穿越军都山,地形起伏较大,无法采用盾构掘进机,只能采取爆破工法。

△施工现场

施工现场像迷宫

八达岭长城站地下建筑面积36143平方米,车站内各类洞室共78个,断面型式多达88种,交叉节点密集,结构异常复杂,施工难度非常大。

△多洞穴施工现场

地质会随施工变化,步步惊心
