Robbins TBM Rosie is First Crossover TBM in the U.S.

Robbins TBM Rosie is First Crossover TBM in the U.S.

A Robbins Crossover (XRE) TBM measuring 9.26 m (30.4 ft) in diameter underwent factory acceptance on May 30, 2017. The machine will be shipped 40 km (25 mi) south to the OCIT-1 site for construction of the Ohio Canal Interceptor Tunnel (OCIT) in Akron. The contractor is the Kenny-Obayashi JV. The TBM, which includes features of both EPB and Hard Rock Single Shield TBM types, is the first Crossover machine to be used in the United States. It will be launched from a 12 m (40 ft) deep portal site and build the first 68 m (226 ft) in soft ground, transitioning to a 183 m (600 ft) long zone of partial face shale before switching to hard-rock mode for the remainder of the drive in full face shale. Probe drilling will be done continuously using two probe drills to determine which mode the TBM should be in.

The machine was dubbed “Rosie” in honour of Rosie the Riveter, an icon representing the American women who worked in factories and shipyards during World War II. Hundreds of “Rosies” including Akron resident Rose May Jacob worked in factories to turn out materials and armaments for the Allied war effort.

The TBM will be shipped in truckloads to the jobsite, with the large cutterhead shipped in four pieces. Tunnel boring is scheduled to begin in August of this year.

The OCIT Project for the City of Akron consists of the construction of a conveyance and storage tunnel system to control Combined Sewer Overflows (CSOs) for several regulators in the downtown Akron area. The EPA (Environmental Protection Agency) mandated project includes the 1.89 km (1.17 mi) conveyance and storage tunnel, as well as drop shafts, diversion structures, consolidation sewers, and related structures.  The consent decree specifies that the tunnel must be operational by December 31, 2018.
