Cutting-Edge technology for the Garisenda tower

CASE STUDIES

Cutting-Edge technology for the Garisenda tower

The Garisenda Tower is one of the so-called two towers of Bologna, a symbol of the city built in the late 11th and early 12th century. The historical slope is due to an ancient subsidence of the foundation ground, which led to its lowering to the current 48 metres in 1353. The initial height was in fact 60 metres, but the steep slope risked causing it to collapse, so it was lowered by 12 metres to prevent this.

Since 2018, the Garisenda has undergone consolidation works and has been constantly monitored to verify the structure’s behaviour over time and ensure its safety and preservation.

The current monitoring system of the Garisenda Tower supplied by Lunitek in the first half of 2022, based on the acoustic emission technique, a little-known and little-exploited monitoring technique with great potential, consists of a total of 16 ultrasonic sensors, 2 AEMission dataloggers for data synchronisation and recording, and a 4G router for remote acquisition on a server. An SFTP space, accessible from the Internet using the appropriate credentials, is also available to allow technicians to access and process the data. This system has already allowed a risk profile of the structure’s stability to be elaborated in almost real time.

The surveys and analyses are carried out by the Polytechnic University of Turin, and the data collected were processed using modern multi-parametric statistical analysis techniques to identify correlations between the data that most influence the stability of the structure.

In recent months, the reports from the sensors have increased, detecting abnormal vibrations and oscillations. The monitoring system will be expanded to allow a more detailed analysis of the structure.

Yeti – compact and lightweight measurement sensor based on GNSS technology

Yeti is a compact and lightweight measurement sensor based on GNSS technology ideal for low budget projects.

It was designed for monitoring and early-warning of critical areas in the presence of hydrogeological risk.

Landslides, subsidence, volcanos, slope instability are some of the most common applications of the system but not only. All infrastructures such as civil buildings, water pipelines, energy plants, railways, bridges, dams, quarries, viaducts can be monitored using Yeti.

EGU General Assembly 2023 / Vienna, 23–28 April 2023

EGU, the European Geosciences Union, is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide. It was established in September 2002 as a merger of the European Geophysical Society (EGS) and the European Union of Geosciences (EUG), and has headquarters in Munich, Germany.

The EGU General Assembly 2023 brings together geoscientists from all over the world to one meeting covering all disciplines of the Earth, planetary, and space sciences. The EGU aims to provide a forum where scientists can present their work and discuss their ideas with experts in all fields of geoscience.

LUNITEK will exhibit at the EGU General Assembly 2023 and we’ll be delighted to welcome you at our stand providing information on earthquake monitoring systems and our products.

LACSC / QUITO – ECUADOR, 03-05 October 2022

LACSC – Latin American and Caribbean Seismological Commission IV ASSEMBLY

Lunitek with its regional partner Geosis Ingenieria from Bogotá – Colombia, participated in LACSC, the Latin American and Caribbean Seismological Commission IV ASSEMBLY event, in the city of Quito – Ecuador. This important meeting was attended by different public entities and private companies that carry out seismic monitoring activities with national, regional and local networks, volcanological monitoring networks, as well as researchers and experts in seismology from different Latin American countries.

Our stand had a good participation of the different attendees during the 3 days of the event and was attended by Paloma Sandoval (Commercial Manager) and Carlos Lozano (Geosis Engineering Director). Our instruments caught the attention of the attending professionals, highlighting the presentation of the Hermes equipment, Triton Seismographs with different bandwidths, Sentinel GEO and Accelerographs for recording strong ground motion.

What was most appreciated about our products was their versatility, the variety of sensors and digitizers, their design, easy portability, power backup and adaptability in communications. The affordable costs, robustness in their construction and ease of use in permanent networks as well as in temporary monitoring of seismic noise, the possibility of making arrangements for monitoring networks with different equipment configurations, were other aspects that were highlighted during the presentation of the different equipment.

Circo Massimo monitoring during the Maneskin concert

The Circo Massimo is the largest building for spectacle of antiquity and one of the largest of all time (600 m long by 140 m wide) and is linked by legend to the very origins of Rome: here, in fact, the Rape of the Sabine Women took place.

On occasion of the Maneskin concert on 9 July 2022, Lunitek installed, on behalf of the Polytechnic of Turin and Fine Arts, 7 seismometers to record and assess the vibrations caused by the concert and their impact on the remains of the Circus.

Structural Health Monitoring System Installed in Two Skyscrapers in Medellín – Colombia​

Through our Colombian dealer we carried out SHM systems installed in two Skyscrapers in Medellín, Colombia. In total 6 Triton accelerographs were installed together with accessory devices that allow the equipment to connect to the network, and therefore the visualization and the remote acquisition of recorded data. The accelerographs were installed on the basement or lower level, on the 16th and on the 34th floor of the Towers.
