Tunnel-Bore

IMG_6234.jpeg

A miniaturized, pneumatic tunnel-boring machine designed and built by undergraduate engineering students as the prototype for a proposed high school team design competition

What is a Miniature Tunnel Bore?

What Does It Do?

Tunnel bores dig long, cylindrical, structurally sound tunnels through anything rock hard rock to sand often to make way for underground rail and transport projects. It is a safer alternative to drilling and blasting.

How Does It Work?

Traditional, full size tunnel bores use a rotating cutting head to dig through the Earth. To miniaturize the design, we have used a drill bit on the tip of a screw auger to accomplish the same task. In both cases, the devices are turned by a drill machine, though ours is significantly smaller

Where Can I Learn More?

A rapidly growing industry, both full scale tunneling and micro-tunneling are on the rise. From Robbins Tunneling to Elon Musk's Boring Company, tunnel bores are the future of geological engineering. An excellent detailed breakdown of the science behind Tunnel-Boring machines can be found below

Our Tunnel Bore

Straightforward Process; Straightforward Design

Simple, sturdy, and plainly effective: We have emphasized accessability and reliability in our design while keeping the build as affordable as possible. High schoolers who participate in the CU Hyperloop Bore Design Competition will find it easy to learn from our unconcealed design whose streamlined component orientation allows for easy recreation, modification, and supplementation.

"There I was, a-digging this hole
A hole in the ground, so big and sort of round."
