ULMA drainage in the Cuautitlan-Buenavista Suburban Train tracks, in the State of Mexico

This year, improvement works have been carried out on this stretch of the Suburban Train, as the area was sometimes flooded by heavy rains, interrupting the service. Therefore, we decided to implement a complete drainage system on the sides of the tracks, for the correct evacuation of rainwater, thus avoiding major problems and enabling a continuous and safe service.

The premanufactured ULMA channels made of polymer concrete have been chosen for their high quality and short installation time. This material resists compression better than traditional concrete and remains unaltered in the face of temperature changes. In addition, because it comprises premanufactured canals, it saves time of installation, which is important in this class of works, in which the public services are altered. This work was carried out in approximately 6 weeks with work shifts of 4-5 hours.

Throughout the route, 900 linear metres of the SU200 model with a cascade slope and a galvanised steel ribbed grid were installed. After conducting a specific study for this project, it was seen that this canal had the optimum hydraulic capacity for the specific needs of the work. As for the grid, good fixation was the most important aspect, which was achieved thanks to the two barriers per linear metre it contains.

In 2008, this train service was implemented between the Federal District and the state of Mexico, with a line departing from Cuautitlán to Buenavista. Thanks to this project, an alternative transportation emerged for all citizens residing in these areas and who need to fast, safe transportation from the state of Mexico to the capital of the country.
