📋 Tender Overview
The production of segments concrete structures that will form the rings that will cover the underground tunnel through which the trains of Line 2 of the Lima and Callao Metro will move is progressing at a good pace. Since the end of 2019 the manufacturing plant of these structures has been operating at 100 and so far more than 25340 segments are ready with which 3620 concrete rings can be formed of the 13000 that are needed in total for lining the entire tunnel to be built.The production of the segments will guarantee that the two tunnel boring machines on Line 2 can soon start working at an accelerated pace to excavate and simultaneously place the rings. Each ring that will be placed by the aforementioned machinery is made up of seven segments with which 100 of the tunnel wall will be covered whose diameter is 10 meters. Each segment weighs approximately 6.5 tons while the ring has a total weight close to 42.5 tons.There are two tunnel boring machines that will install these pieces of concrete. The TBM No. 1 that will dig from the San Juan de Dios station in San Luis heading to Callao will start working next July. While No. 2 will enter through the Insurgentes station in Bellavista Callao heading west. In this way the tunnel will be drilled and lined with concrete on two work fronts covering a total of 34 kilometers.It should be noted that Line 2 of the Lima Metro will have 27 stations in total not counting the 8 that will have the Av.
