How is quality control performed in a pile driving or microtunnelling project?

Q: How is quality control performed in a pile driving or microtunnelling project?

Quality control in a jacking or microtunneling project includes previous geotechnical and topographical studies, verification of the quality of materials such as pipes, continuous monitoring of parameters during the execution and final tests of watertightness, resistance and alignment. At Eurohinca we follow procedures based on international standards such as those of the Pipe Jacking Association (PJA) to guarantee precision, safety and durability in each project.

The quality control in a work of driving or microtunneling is a comprehensive process that ensures that each phase of the project meets the expected technical, safety and performance standards.

The main actions include:

Preliminary studies and design
Geotechnical, topographical and layout evaluation to ensure feasibility and minimize risks.
Material control
Verification of the quality of the pipes and components, such as those used in submarine emissaries or marine catchments.
Monitoring during execution
Monitoring of parameters such as thrust pressure, alignment, ground speed and ground conditions to detect deviations and correct them in real time.
Final tests and trials
Tightness, structural strength and final alignment tests prior to delivery of the work.

At Eurohinca We apply procedures based on international standards, such as the recommendations of the Pipe Jacking Association (PJA), to guarantee precision, durability and safety in all our works.
