When the commotion of construction must be minimized, try horizontal directional drilling!📺 Get a year of CuriosityStream AND Nebula for 26% off, just $15/yr! http://www.curiositystream.com/practicalengineeringWatch the Coding Train video: https://youtu.be/FfCBNL6lWK0Play the simulator: https://codingtrain.github.io/Directional-Boring/Like laparoscopic surgery for the earth, horizontal directional drilling (or HDD) doesn’t require digging open a large area like a shaft or a bore pit to get started. Instead, the drill can plunge directly into the earth’s surface. From there, horizontal directional drilling is pretty straightforward, but it’s not necessarily straight. In fact, HDD necessarily uses a curved alignment to enter the earth, travel below a roadway or river, and exit at the surface on the other side.Practical Engineering is a YouTube channel about infrastructure and the human-made world around us.
