亲眼目睹的工程小奇观。

之前的样子:

每次上下班的路上都要经过一个高架桥的工地。高架桥的主体部分是一座斜拉桥。这座桥的建设已经有一年多了。每天都从他下面经过，看着他从水泥。主塔到放出斜拉绳到斜拉绳拉直连接桥面。但是两端的引桥部分离。这座桥始终有很长一段距离。一直以为这是一座立体桥，旁边的引桥最终是要。以某种角度从他从桥上或者是桥下跨过去。反正每天看着他一点点的建设。慢慢的完成，也没有感觉到什么异样，因为每天的变化都是觉察不出来的。但是就在上个礼拜。因为工作关系在单位上了一次夜班。第2天早上下班回来，经过这座桥时。发现好像有什么地方不对劲，怎么桥的方向。一夜之间转了90度。恍惚间一度怀疑自己是不是走错路了，但是这条上下班的路怎么可能会走错呢？手机那确认没错，这座桥确实在一夜之间就旋转了90度。真是难以置信。仿佛。每天逆行拿着铁锹箩筐，准备去。移山的愚公，突然发现眼前的大山不见了被。玉皇大帝派来大义士把那两座山搬走了一样，让人吃惊。

后来开启无人机，从空中远远的看了一下，发现这确实是一次个非常。有意思也非常聪明的工程小奇观。原来这座高架桥要横跨很多条铁路。如果按照最终的方向施工的话，就会阻断铁路的交通。因为高架桥的走向与铁路线的走向是垂直的。于是他在桥的搭建过程中采取了寓意铁路平行的方向，在整个桥面都搭建完成之后。不知道用什么方法将这么巨大的桥面水平旋转了90度。正好与两端的引桥对接。很可惜没有目睹这一过程。要不然一定是很壮观的。

网上评价中国素有基建狂魔的称，呼眼前这座不大不小的工程。确实让我小小的震撼了一下。

Every time I commute to work, I pass by the construction site of a viaduct. The main part of the viaduct is a cable-stayed bridge. The bridge has been under construction for more than a year. Every day passed under him and watched him pass from the cement. The main tower to the release of the cable-stayed rope to the cable-stayed rope straightened to connect the bridge deck. However, the approach bridges at both ends are separated. The bridge is always a long way away. I always thought that this was a three-dimensional bridge, and the approach bridge next to it was finally wanted. At some angle, he crossed over the bridge or under the bridge. Anyway, I watched him build a little bit every day. I finished it slowly, and I didn't feel anything unusual, because the changes every day are imperceptible. But just last week. Because of work, I worked a night shift in the unit. On the second day, when I came back from work in the morning, I passed the bridge. I found that there seemed to be something wrong, how the direction of the bridge. It turned 90 degrees overnight. In a trance, I wondered if I was on the wrong path, but how could this commute to and from work be wrong? The phone confirmed that the bridge did rotate 90 degrees overnight. It's unbelievable. Seems. Every day retrograde, holding a shovel and basket, ready to go. The foolish man who moved the mountain suddenly found that the mountain in front of him was gone. The Jade Emperor sent a righteous man to move the two mountains, which was surprising.

Later, I turned on the drone and looked at it from a distance from the air, and found that it was indeed a very one. Interesting and also very clever little spectacle of engineering. Originally, the viaduct had to span many railways. If the construction is carried out in the final direction, the traffic of the railway will be blocked. Because the direction of the viaduct is perpendicular to the course of the railway line. So he took the direction of the parallel railway, which means that the bridge was built, and the entire bridge deck was built. I don't know how to rotate such a huge bridge deck horizontally by 90 degrees. It is just docked with the approach bridges at both ends. It's a pity that I didn't witness this process. Otherwise, it must be spectacular.

Online evaluation: China is known as the infrastructure madman, and this small project in front of him is not small. It really gave me a little bit of a shock.
