Panama power

摘要

By this month, Seli will have tested and delivered at its factory in Aprilia, Italy, the second of two very similar EPB TBMs to be launched shortly in Panama on sister drives through lahar, a variable volcanic rock rarely met by tunnellers.Each machine will be used to construct a headrace tunnel, one for the Monte Lirio hydropower plant and the other for the Pando project, just upstream. The run-of-river projects are on the Chiriqui Viejo River, which runs west in Chiriqui province, close to the border with Costa Rica.
