Microtunneling is an alternative method to conventional tunneling. Microtunneling is used in applications under high water pressure and unfavorable ground conditions. Michels deploys a remotely controlled, guided microtunnel boring machine (MTBM) to mine tunnels up to 10 feet in diameter. A pipe-jacking operation provides continuous support for the excavation, making it effective for construction under roadways, waterways and other challenging situations. Hydraulic jacks inside the entry shaft accurately propel the MTBM to the retrieval shaft. A closed loop system takes spoils to the surface where slurry is cleaned and reused after spoils are removed for proper disposal. Underwater Retrieval Michels is one of the most experienced contractors at successfully executing underwater retrievals of a MTBM. Michels has added to its resume completing over 25 wet retrievals. This specialized tunnel construction method starts in a shaft on shore and proceeds to an end point under a waterway. At that precise location, the newly constructed tunnel is sealed, and the MTBM is detached and lifted onto a barge. The vast experience and design-build capabilities makes us a qualified partner.
