Monitoring

Joint and deformation monitoring

By Reinier Brongers

In the latest COB tunnel deformation monitoring report for emerged tunnels various modern monitoring tools are described. For instance to monitor the movements of tunnel sections over the joint f.i. with a 3D joint sensor. In the past the monitoring was done with 3 potenial meters, each demanding a node to communicate with a gateway. The installation is demanding time and the dimensions of a cabinet to cover the meters is big. We will present data form various tunnel projects thus showing attendees the advantages of having all data in one screen. This new generation of sensors is very compact, easy to install and is not demanding any additional infrastructure or support. They do have their own battery and SIMCard and will work everywhere there is a mobile network available. The sensors also measures the temperature. Alarm settings can be given in and frequency can be changed in time if needed. Data can be imported by means of an API to any platform, tidal data as well as weather data can be integrated to the sensor data. Besides this we will shortly go into the deference between high frequency tiltmonitoring and static tilt monitoring. High frequency monitoring will show the real dynamic behaviour of any object.

Tunnels: a heritage to regenerate. Italian EU funded program on refurbisment of roadtunnels

By TBA

Tunnels: a heritage to regenerate. In Italy, hundreds of tunnels, bridges and viaducts are needed to cross hills, valleys, and streams. Regenerating maintenance interventions on this important heritage and preventive maintenance of more recent assets have become urgent. No other country has so many. If we look at tunnels, Italy alone has half of all European tunnels, totalling 500 kilometres. However, this important heritage is ageing: most of the bridges, viaducts, tunnels and the motorway network itself were built between 1960 and 1980. In addition, the network has to cope with the stress caused by an average daily traffic of 40,000 vehicles per section (compared to 27,000 in France, for example), and with a particularly fragile territory and its hydrogeological instability. Suffice it to say that two thirds of the landslides in Europe occur in Italy and that this figure is likely to increase with the extreme events caused by climate change.It has become imperative to start a campaign of investigations on bridges, viaducts and tunnels considering the wear and tear caused by ageing, but also extreme weather events and the increasingly evident climate change, which affect road transport infrastructure. With support of the EU funds were allocated to start this campaign and Italy is now in the middle of this campaign. How far are they and what lessons have they learned so far?

Assetmanagement for tunnels

Developments in tunnel asset management with CERN

By Vanessa Di Muro

The European Laboratory for Particle Physics (CERN) hosts the most powerful particle accelerator ever built, the Large Hadron Collider (LHC). To guarantee the safe running of the particle accelerators, the maintenance of CERN underground infrastructure plays an important role. Ageing and deterioration of tunnel defects are becoming more evident and inevitable. Detecting and monitoring cracks in tunnels are crucial for maintaining the structural integrity and safety of the infrastructure. However, access to most of the underground areas is regulated and granted only during specific periods of the year, for 1-2 months. Such limited time poses a great challenge to the visual inspection and field monitoring of the CERN infrastructure over tens of kilometres. The presentation will focus on CERN Tunnel Asset Management strategy and the implementation of smart monitoring technologies used to inspect and assess CERN large-scale infrastructure. This includes automated crack detection systems by using advanced robotics solutions and distributed fibre optic sensors, that can provide real/time data on structural changes, enhancing preventive maintenance activities.

Tunnels getting more independent from the power grid: an important step in energy transition

By Rene List

The Austrian highway road operator ASFINAG has made a Expressway with more than 16km length in Vienna, including six tunnels within and the traffic control centre, self-sufficient by generating its energy. This energy is used for the normal daily consumption of the route, and the surplus is stored in large batteries. To transport and distribute the energy, ASFINAG has installed its own medium-voltage network. This allows energy to be generated, stored and used where and when needed. An central energy management system controls the energy flows and ensures monitoring. In a power outage around Vienna, the most critical systems on this layout can continue to operate for about ten hours. Learn more about the status, the methodology, the future of this project, and possibilities for your tunnel project.

How to estimate and how to decide ; a practical guide for tunnel relining; first experiences and lessons learned

By Daniele Di Fiore

Autostrade per l’Italia, with its engineering firms TECNE, has developed an approach to refurbish existing tunnels named Tunnel Renewal Strategy (“TRS”). TRS aims to achieve service life’s renovation through 8 different relining treatments. Over the last three years the design of the solutions has been developed and studied and key factors, leading to success or to the need for further improvements, have been identified. Beyond this, the method for selecting the right treatment among the solutions is driven by a multicriteria analysis including a supporting decision tool, based on asset management best practice, to account for others then technical aspects. Sound decision making is becoming part of the asset management strategy of the Organization, involving the Client and the Contractor in a continuous exchange of insights about budget limits, service life of the solutions and needed technologies to minimize the impact and keep serviceability of a very busy infrastructures.

Automated concrete relining technique– when time is of the essence

By Stefano Guanziroli

HINFRA has developed a technology named ETLR (Extruded Tunnel Lining Regeneration), with the scope to build new linings for existing tunnels adopting an ultrafast horizontal slip-forming. The ETRL processing train is a machinery consisting of several modular units, each solving a specific function. The incremental industrialization of set of operations, typically the demolition, the surface preparation, and the new lining phases, combined with the performances of the special concrete, allow to target productivity rates far from the traditional methods in use in the industry. The engineered Fiber-Reinforced Concrete (FRC) is characterized by high early-age strength parameters, that allow a rapid slip-form at a predetermined time. A solid step into the technology implementation has consisted in the construction of a real scale extrusion facility, where the main components of the ETLR train are designed, produced, and tested. The solution was then transferred to pilot projects starting from 2023.

Monitoring the integrity of the Rotterdam metro tunnel

By Edo Noordermeer

We present the monitoring system installed in the Rotterdam metro tunnel to safeguard the integrity of the immersed joints for the coming 10 years. In 2015, large-scale damage was detected in the immersion joints of the metro tunnel in Rotterdam. It was found that the Gina seals in the joints were pushing themselves inwards, causing damage both to the concrete tunnel walls and to the fixation of the support structures. An extensive renovation project was set up to repair the damage and to ensure that the tunnel joints are fit to last another 50 years. As part of this effort, an extensive sensing system was installed to permanently monitor the integrity of the joints. The system consists of a variety of sensors, measuring amongst others joint widths, shape and position of the Gina profiles, forces in the fixation brackets, water pressure and temperatures. Several systems were custom developed for application in this tunnel. In total, more than 1500 sensors are now continuously measuring the state of the tunnel joints. Data from all sensors is automatically transferred from the tunnel to a central cloud-based server and presented in near real-time via interactive dashboards in an online portal. Thresholds have been configured for the various measurements - when a measurement exceeds a threshold, an alarm is raised automatically, and a ticket is generated for follow-up action. The monitoring system provides invaluable input to the tunnel asset management team, not only about the current state of the tunnel, but also predicting future problems early, before they lead to damage. In this presentation, we describe the motivation for installing this unique monitoring system. We present the design of the various sub-systems, as well as the associated data processing pipeline, visualization dashboards and ticketing system for follow-up actions. We also present results from the first two years of measurements. Finally, we give some recommendations and good practices for future tunnel monitoring projects.
