Tunnels

RK-TYCSA is able to offer its customers the best solutions for tunnels, drains and technical galleries. TYCSA masters all tunnel execution techniques in all types of terrain and has its own drilling equipment with diameters of 500 to 5500 mm, which it has used in over 100 jobs around the world.

Techniques and equipment:

• Excavation with a tunnel boring machine (Ø 1.80 to 5.50 m.): Earth-pressure balance (EPB) tunnelling, boom-type heading TBMs, back-ups, debris clearing equipment (trains, etc.), pressurisation equipment (suppressors, hyperbaric chambers, SAS, etc.)
• Excavation with a microTBM (Ø 0.50 to 2.50 m.):
• Pile driving
• Prefabricated arches
• Boreholes
• Associated civil engineering and refurbishments

We offer the full range of engineering specific to each job: feasibility study, geotechnical analysis of the project, geometry and layout, environmental conditions, and we offer the ideal solution in terms of the equipment to use (reconditioning of own or third-party equipment, own construction, and purchase of new equipment) and the shell, including its design.
