Q: How are unforeseen events or unexpected ground conditions managed during the execution of the work?

At Eurohinca, geological contingencies are managed through real-time monitoring, adjustment of thrust and torque parameters, drainage systems, inspection cameras and direct communication between engineering and site. Their international experience and the use of specialized excavation equipment allow them to deal with ground changes, seepage or unexpected pressures without compromising the safety and accuracy of the tunnel.

At Eurohinca, management of unforeseen events and unforeseen geological conditions is part of a structured working protocol, based on the experience accumulated over more than 25 years of national and international projects.

Prior to the start of each construction project, a detailed geotechnical and topographical analysis, However, during excavation, variations may occur, such as changes in soil density, the presence of boulders, seepage or unexpected water pressures.

To address them, Eurohinca applies specific measures such as:

Continuous monitoring of the excavation face sensors and hydraulic control.
TBM thrust and torque recalibration, adjusting parameters in real time from the control cabin.
Auxiliary pumping and drainage systems to stabilize saturated or leaking areas.
Specific technical interventions by means of manholes or inspection chambers.
Direct collaboration between the site team and the engineering department, ensuring quick and safe decisions.
Revision of the tunnel layout or section in coordination with the client when the terrain requires it.

Thanks to its fleet of specialized excavation equipment and its experience in complex hydraulic works, Eurohinca minimizes the impact of unforeseen events and ensures the continuity and security of execution, The alignment accuracy and the quality of the final result are maintained.
