International competition: Torpedo drilled its way in to the final

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 to the final of a global competition with the ?Dirt Torpedo?. WIKA co-sponsored the project by giving measurement technology and a grant.
Students 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 bulk manufactured it into the final round
Of the total of 400 entries in your competition, called by the American entrepreneur Elon Musk (co-founder of Tesla among others), twelve made it through to the ultimate round. The finalists were tasked with drilling a 30-metre-long tunnel in California?s Mojave Desert. However, because of conditions being changed on-site at short notice, only the crew from TU Munich could actually start. The students at DHBW Mosbach were disappointed about the way your competition ended, which was, ultimately, not just a competition at all. Nevertheless, they’re justifiably proud of their ?Dirt Torpedo?.
Student competition project with WIKA measurement technology
The team spent per year working on the 2 2.63-metre-long tunnel boring machine. The ?Dirt Torpedo? progresses at a speed of 5.4 metres each hour. That?s one metre more than a snail ? and snails are usually faster than 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 against the tunnel wall through twelve valves to support 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 to allow them to permanently resist the abrasive forces of the concrete. No residues can abide by their surface. WIKA?s sponsorship of the ?Torpedo? project amounts to a total of 20,000 euros.
Long-term collaboration with the cooperative state university
The company and DHBW Mosbach have been closely associated since 1985. As a dual partner, WIKA enables future specialists to graduate in a current 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 offers the status of a ? เกรดวัดแรงดัน ?, which means it offers the university with ?an extraordinary level? of support. Partner companies are involved in the university through the Pro DHBW Mosbach foundation, and therefore promote the dual system. Furthermore, Alexander Wiegand may be the Chairman of the Board of Trustees.
