PROJECT OBJECTIVE

New railway platform

The project consisted of the construction of a new railway platform from the underpass of the C-31 highway to terminal T1 of Barcelona’s El Prat Airport.

The layout of the two tracks was more straight, connecting both terminals under the runways and terminating under Terminal T1, at the same point as Metro Line 9. Of the 4.5 km total, 2.8 km ran in an EPBtunnel.

This train offered faster and more direct access from the center of Barcelona, with frequencies of approximately 15 minutes, compared to the 30 minutes of the previous system.

How we made it happen

Action plan, services and instrumentation

This line will run from Paseo de Gracia (eventually to be replaced by La Sagrera station), Sants Station, El Prat de Llobregat and the new stations of Terminal 1 and Terminal 2 of the airport.

In this way, it will take advantage of the R2 line until after the Prat station, where the new railway platform will be built to connect with the airport, which will be mostly subway.

Grupo Álava provided the monitoring services during the works, including all the installation, instrumentation design, supply, measurements, data monitoring and presentation to the client through reports and a computer platform. In the specific situation of the tunnel boring machine passing through the runway of El Prat airport, continuous monitoring of different geotechnical parameters was proposed.

All the sensors were connected to a datalogger that collected and sent the data for analysis.

The facility was critical because of the restricted restricted access and the short lead time available, coinciding with runway maintenance. runway maintenance. However, the work was successfully completed successfully in just 18 hours, minimizing disruption and achieving a continuous disruption and achieving a continuous monitoring system for geotechnical geotechnical parameters in an area that is difficult to access by traditional methods. traditional methods.

RESULTS AND ACHIEVEMENTS

Infrastructure monitoring

The monitoring system installed made it possible to maintain the airport runway in optimal conditions during the construction of the railway tunnel, recording the evolution of deformations in different sections and simulating possible seating basins caused by the tunnel boring machine.

Se proved to be a reliable solution for minimizing risks in other infrastructures other infrastructures, with rapid installation despite restricted access, and its and its data was validated by topographical measurements. measurements.
