Being faster than a snail is a tremendous challenge for a tunnel boring machine. Students at DHBW Mosbach have mastered this, and also have made it through to the final of a global competition with the ?Dirt Torpedo?. WIKA co-sponsored the project by giving measurement technology and a grant.
Blunder at DHBW Mosbach proudly presented their ?Dirt Torpedo?. DHBW Rector Prof. Dr. Gabi Jeck-Schlottmann, Gerhard Lauth, Managing Director of the Pro DHBW Mosbach foundation, and CEO of WIKA Alexander Wiegand SE & Co. KG, Alexander Wiegand, also attended the presentation of the innovative tunnel boring machine.
Tunnel boring machine made it in to the final round
Of the full total of 400 entries in the competition, called by the American entrepreneur Elon Musk (co-founder of Tesla and others), twelve managed to get through to the ultimate round. The finalists were tasked with drilling a 30-metre-long tunnel in California?s Mojave Desert. However, due to conditions being changed on-site at short notice, only the crew from TU Munich were able to start. The students at DHBW Mosbach were disappointed about the way the competition ended, which was, ultimately, not just a competition at all. Nevertheless, they are justifiably pleased with their ?Dirt Torpedo?.
Student competition project with WIKA measurement technology
The team spent a year working on the two 2.63-metre-long tunnel boring machine. The ?Dirt Torpedo? progresses at a speed of 5.4 metres per hour. That?s one metre greater than a snail ? and snails are often faster when compared to a conventional tunnel boring machine.
WIKA?s measurement technology is situated in the rear area of the ?Dirt Torpedo?. From there, a fibre-reinforced, fast-curing concrete is pressed contrary to the tunnel wall through twelve valves to aid it. To monitor the pressure of the concrete feed, WIKA provided twelve diaphragm seal systems with mounted transmitters of model S-20 and a 1?10 V output signal. The flush diaphragms of the diaphragm seals are extra strong so they can permanently resist the abrasive forces of the concrete. No residues can abide by their surface. WIKA?s sponsorship of the ?Torpedo? Bona Fide amounts to a complete of 20,000 euros.
Long-term collaboration with the cooperative state university
The business and DHBW Mosbach have already been closely associated since 1985. As a dual partner, WIKA enables future specialists to graduate in an ongoing total of seven degree programmes, with practical phases at WIKA?s headquarters in Klingenberg. Up to now, around 250 WIKA students have graduated from the DHBW. WIKA also has the status of a ? Zen ?, this means it provides the university with ?a fantastic level? of support. Partner companies get excited about the university through the Pro DHBW Mosbach foundation, and thus promote the dual system. Furthermore, Alexander Wiegand may be the Chairman of the Board of Trustees.
