@tunnel.engineering: ✅Horizontal Directional Drilling (HDD) is a trenchless method to install underground pipelines or conduits by drilling a guided bore, enlarging it, and pulling the pipe through. It allows crossing obstacles like rivers or roads without large surface excavation, using drilling rigs, bentonite fluid, and a steerable drill head. 👨‍🎓You can learn about all tunnel construction methods in our Online Tunnel Engineering Course (CPD Certified).
