Construcciones Urales<\/strong> is carrying out the construction of Phase 1 of the Santa Martha station<\/strong>, part of the mass electric transportation system known as the Elevated Trolleybus. The project also includes the execution of a curved viaduct that will connect this station with Line 8 of the Trolleybus, coming from Constituci\u00f3n de 1917 station (Mexico City).<\/p>\n

The project is divided into two phases, Phase 0 and Phase 1, due to the station\u2019s location at the boundary between Mexico City and the State of Mexico, and therefore managed by two different administrations.<\/p>\n

Once both phases are completed, the station will also enable the interconnection of the two elevated trolleybus lines that will converge there: Line 8, connecting Constituci\u00f3n de 1917 with Santa Martha, and Line 10, connecting Santa Martha with Chalco.<\/p>\n

In addition, the Santa Martha elevated trolleybus station will form part of the Modal Transfer Center (CETRAM) Santa Martha<\/strong>, which, through pedestrian walkways, will connect to the existing transport systems: metro, bus, cable car, and elevated trolleybus.<\/p>\n

<\/h3>\n

Construction of Phase 1 of the Elevated Station<\/h3>\n

The construction of Phase 1 of the elevated station is developed across four levels:<\/p>\n

    \n
  • Street level \u2013 bus terminal.<\/strong><\/li>\n
  • Concourse\u2013walkway level<\/strong>, with a built area of 704 m\u00b2.<\/li>\n
  • Trolleybus platform level<\/strong>, with a built area of 1,178 m\u00b2.<\/li>\n
  • Roof level<\/strong>, with a built area of 581 m\u00b2.<\/li>\n<\/ul>\n

    The structure as a whole is resolved with large reinforced concrete frames, made up of columns with a section of 2.4 x 2.9 m and variable-depth beams ranging from 2 to 3 m. These support the different elevated levels, which are executed with various steel structures.<\/p>\n

    These large frames are founded on reinforced concrete pile caps, 2.5 m deep, placed at \u20136.5 m below street level. The loads are transferred to reinforced concrete piles with a 1.5 m diameter and lengths of 67.5 m. The pile caps of the different frames are braced with foundation beams measuring 2 x 2.5 m.<\/p>\n

    Key figures for this work include:<\/strong><\/p>\n

      \n
    • 878 m of piles (1.5 m in diameter).<\/li>\n
    • 2,977 m\u00b3 of structural concrete.<\/li>\n
    • 844,000 kg of reinforcement steel.<\/li>\n
    • 548,000 kg of structural steel.<\/li>\n<\/ul>\n

      <\/h3>\n

      Construction of the Curved Connecting Viaduct<\/h3>\n

      The curved viaduct, which will connect Line 8 of the trolleybus with the Santa Martha station, has column heights of up to 15 m. It begins with a deck section wide enough for two-way trolleybus circulation. Shortly after, the deck splits into two narrower branches with one-way circulation each: the north branch and the south branch, both connecting to the station\u2019s structure.<\/p>\n

      Both branches are also linked in the central area to allow for trolleybus direction changes.<\/p>\n

        \n
      • The north branch<\/strong>, 104.56 m long, consists of a hyperstatic structure with three spans of 28.21 m, 28.44 m, and 18.22 m, plus an isostatic structure of 29.69 m.<\/li>\n
      • The south branch<\/strong>, 76.82 m long, consists of a hyperstatic structure with two spans of 30.92 m and 18.44 m, plus an isostatic structure of 27.76 m.<\/li>\n<\/ul>\n

        The deck typology of the viaduct (both branches and the central junction) is mixed, formed by a 25 cm thick reinforced concrete slab over a steel box girder with a depth of 1.63 m. The deck rests on variable-depth caps connected to reinforced concrete columns of variable height.<\/p>\n

        The foundation of the columns is executed with reinforced concrete pile caps, 3.75 m deep, placed at \u20138 m below street level. Each support transfers the load to the ground through six reinforced concrete piles, 1.5 m in diameter and between 64 and 74 m long, depending on the support\u2019s location.<\/p>\n

        Key figures for this work include:<\/strong><\/p>\n

          \n
        • 373 m of piles (1.5 m in diameter).<\/li>\n
        • 479 m\u00b3 of structural concrete.<\/li>\n
        • 493,000 kg of reinforcement steel.<\/li>\n
        • 655,000 kg of structural steel.<\/li>\n<\/ul>\n
