If you’re from Madrid, you must have looked at next year’s work calendar and noticed a small problem: there isn’t a single day of rest from Easter (March 23-24) to Monday, August 16.
139 days.
At least we have weekends and holidays left that we usually save for the summer. Without the latter, from Monday to Friday, Madrid residents will have 100 working days ahead of them. Are you getting an idea?
Imagine doing this without rest
Mayarit, worked for 127 days without rest
This is the experience of the Mayarit tunnel boring machine, which works underground in the capital and which is very close to reaching Atocha at the moment.
This huge tunnel boring machine weighing 1,500 tons spent 127 days digging the soil of Madrid without rest. Without rest, literally. For 24 hours a day, overseen by a team of 300 people, Merritt proceeded to operate the city’s underground tunnel along which Metro Line 11 would be extended.
The task of this extraordinary machine is to dig a tunnel about three kilometers long to connect the Comilla station of Carabanchel with the Palos de la Frontera in the vicinity of Arganzuela. Along the way, the tunnel boring machine removed about 189,000 cubic meters of earth. Imagine a 50-meter pool used in the Olympic Games. Now multiply by 75.
The progress of the machine worked so well that it arrived at Palos de la Frontera station a month ahead of schedule. Community in Madrid released a spectacular video showing the machine Break through the last wall Before reaching the subway station. This milestone was made possible because Myarit advanced at an average rate of 18.6 meters per day when an advance of 15 meters per day was estimated. Madrid reached 22.8 meters per day between Rio and Palos de la Frontera.
If you think that these figures are not very spectacular, with the traditional method, which was used in some parts of the line extension due to the peculiarities of the terrain, the technicians managed to advance only 50 meters per month.
Once it arrived in Palos de la Frontera, technicians spent three weeks testing the machine to avoid any malfunctions during the process. Once finished, work resumed in late September when Mayritt again sped up to Atocha. 700 meters ahead before entering the capital’s most important train station.
Once reaching the Mayarit station, A new technical stop Before heading to the final destination: Conde de Casale. There, the city is also building an important interchange that will be crucial to the expansion of the aforementioned metro line. This point is not expected to be reached until next year as the distance of that last segment is 1,436 meters.
Along the way, and in the absence of a new update released with the arrival of the tunnel boring machine in Atocha, Mayorit has already left us spectacular numbers, including the 1,606 concrete structural rings that it is installing on its way and which are part of the 25,000 parts, when it is finally installed, Mayorit will finally install. an end
