Bored Tunneling Company designed the tunnel excavator Prufrock, a generation of products with a digging speed of about 250 meters per week, and now the second generation of products in Texas is already 6 times faster than the first generation! Reaching 1.6 kilometers per week, the goal of the third generation will be 1/10 of the human walking speed, and then 50 times faster than the second generation! The digging speed reached 11 kilometers per day!
Even the second-generation products currently in use are far more efficient than the traditional way of working, and boring tunneling companies mainly improve the construction speed by the following aspects: increasing the excavation speed. While improving the cooling system, the power is increased, and the power of the second generation is three times that of the first generation. Prefabricated pipe segments of the tunnel are installed at the same time as excavation, without stopping construction to erect the pipes. You can start working directly on the ground, without the need to dig a pit and hoist into the equipment to start working like a traditional excavator, and the excavator can directly dig out the ground to facilitate the recovery of the machine. The use of rubber-wheeled segmented trucks instead of traditional railway locomotives eliminates time-consuming railway installation and maintenance.
Reduced tunnel costs, vertical integration: in-house production excavators, construction vehicles and precast concrete linings for rapid iteration, tunnel size reduction and standardization: reducing tunnel diameter to 3.6 meters (30% - 60% reduction), maintaining the same tunnel diameter for all projects, uniform standards. Dirt Reuse: Develop alternative methods of excavating tunnels for dirt reuse, including reusing dirt as bricks and pavers for house projects and roadbed beautification.
All-electric: Tunnel construction is carried out using all-electric tunnel equipment, including liner trucks; tunnels are cleaner and ventilation requirements are simpler due to the absence of diesel fumes.
In any case, Musk has established a completely new model in terms of tunneling, all the improvements are only to achieve greater efficiency, and the smaller pipeline is combined with the hyperloop that is about to be fully tested, and the future of boring tunneling companies is worth looking forward to!
