此次南水北调工程中，到底用了多少料，其中有多少颗卷钉，其实都是在工程师的心中的。
　　在湖北省的丹江口大坝上，建筑工人们正在烈日的炙烤下忙碌施工。一个工作人员正细心拧紧坝顶门机轨道上的每颗螺纹卷钉。在他的面前，碧波荡漾的汉江水正穿过大坝闸口一泻千里。

The water diversion project, in the end with much material, how many stars coil nails, in fact, the hearts of the engineer.
Danjiangkou Dam in Hubei Province, construction workers are the hot sun baked under busy construction. A staff member is carefully twist the thread tight dam gantry crane rail on every chip coil nails. In front of him, the blue waves of the Han River water through the dam gates blew.

　　这里就是目前世界上最大的南水北调工程中线水源地丹江口水库。20日，丹江口混凝土大坝坝顶全线贯通，标志着中线水源工程实现重大阶段性目标。

　　在整个工程中，需要用到卷钉的地方很多，现在我们来说几个用量比较大的地主，首先是扎板，每个扎板都是由许多林板连接起来的，那么连接这些木板的就是卷钉。

This is currently the world's largest water source area of the middle route of South to North Water Diversion Project in Danjiangkou reservoir. 20, Danjiangkou concrete dam crest run-through, marking the middle route water source project to achieve a significant level sex target.

Throughout the project, need to use nail volume where a lot of us now, several relatively large amount of the landlord, is the first rolling plate, each rolling plate is composed of many forest board connected, then connect these boards is coil nails.


      再次就是临时栈板，同样是用得比较多的，那么这是两个用量大的，还有其他一个锁碎的地方就不一一列举。
