AVE Palencia-Santander high-speed rail project is a significant infrastructure undertaking aimed at connecting Palencia and Santander in Spain. This project involves the construction of extensive railway networks, viaducts, and bridges, underscoring the need for a strong and resilient foundation. Recognizing the critical importance of ensuring the structural integrity of the concrete piles, the project management sought advanced testing methodologies.
Dextra played a pivotal role in ensuring the robustness of the project’s foundation by supplying Sonitec Crosshole Sonic Logging (CSL) testing tubes. These tubes were instrumental in conducting comprehensive structural integrity tests on the concrete piles of AVE Palencia-Santander USR Package 1 (Palencia – Palencia Norte) and Package 2 (Palencia Norte – Amusco).
Crosshole Sonic Logging is a non-destructive testing method widely employed to assess the quality and integrity of concrete piles. It involves the use of sonic waves transmitted through the concrete between two access tubes, allowing engineers to evaluate the material’s properties and identify potential defects.
Sonitec tubes are specially designed for Crosshole Sonic Logging, ensuring precise and reliable data collection during structural integrity tests. These tubes are embedded in the concrete piles during construction, providing access points for the sonic wave transmission.
