摘要

In the spring of 2015, by the idyllic shores of Oahu, HI, a Robbins 3.96-m (13-ft) diameter main beam tunnel boring machine (TBM) began its long journey. The TBM started its excavation on a 4.6-km (2.8-mile) drive for a new sewer tunnel in Kaneohe, Honolulu, HI. The machine, nicknamed Pohakulani, meaning "Rock Girl" in Hawaiian, launched from a 23-m (74-ft) deep starter tunnel on a mission to bore through almost 4.8 km (3 miles) of basalt bedrock. Contractor Southland/Mole JV is building the Kaneohe-Kailua wastewater conveyance tunnel for the city and council of Honolulu, which will improve waste water infrastructure by eliminating overflows during rain events.
