How strong are those rails laid by those big Chinese machines?

Question

Saw i saw clips of this machine laying concrete down on gravel and rocks and rails for the trains https://vm.tiktok.com/ZS8mnMfM8/ .

But those concrete bars don’t seem to be anchored to anything so how strong are they actually?

That’s a good question! It’s hard to tell from the video, but it’s likely that the concrete bars are anchored to the gravel and rocks underneath them. Depending on the size and weight of the bars, they may need additional reinforcement to ensure they stay in place.
