📋 Tender Overview
At a depth of 20 meters the second tunnel boring machine of Line 2 of the Lima and Callao Metro which was installed at the Insurgentes station and is digging towards the Juan Pablo II station in the Bellavista district has drilled so far more than 600 meters of the thousand meters that correspond to the first phase and has assembled more than 356 concrete rings that serve as support. It should be noted that on September 27 the head of the Ministry of Transport and Communications Richard Tineo activated the power button of the gigantic machine named Micaela which can advance approximately 15 meters per day. The Micaela TBM will also run through the Buenos Aires and Puerto del Callao stations. In this first stage the tunnel boring machine has drilled more than half of the route and has simultaneously installed the concrete structures that support the tunnel. It has already placed 356 concrete rings. The machine is 148 meters long and its cutting wheel is 10.27 meters in diameter. Coming from Germany it is designed for land with groundwater such as those that exist in some areas of Callao. It excavates approximately more than a thousand cubic meters of earth and rock per day. The name of Micaela was placed in honor of the hero of the Independence Micaela Bastidas. It is important to remember that Line 2 of the Lima Metro will have 27 stations. When the train is operational it will transport more than a million people per day and will link Ate and Callao in just 45 minutes.
