What is Microtunneling?
Microtunneling, also known as pipe jacking, is a method used for installing underground pipelines with surgical precision. But why use the term “micro”? It’s because we’re talking about tunnels with diameters as small as 24 inches! Now, that’s a small but mighty revolution.
Microtunneling isn’t just about digging holes in the ground. It’s a precision-driven approach that marries engineering prowess with technological finesse. This method involves the construction of small-diameter tunnels, typically ranging from 24 to 60 inches, using remote-controlled machines known as microtunnel boring machines (MTBMs). These machines elegantly carve out pathways below the surface while maintaining minimal ground disturbance.
The Power Behind Microtunneling
Intrigued? Well, here’s where the power words come in. Picture this: Subterranean Revolution. Microtunneling is reshaping the underground construction game. With its innovative technology and undeniable efficiency, it’s changing how we create tunnels beneath our feet.
