Drilled Piling and Anchoring in Kiruna, Sweden
In the autumn of 2024, Juvatec Oy carried out a demanding drilled piling and anchoring project in Kiruna, Sweden. The project aimed to ensure the stability and safety of a future excavation in a densely built area. This technically challenging work was completed on a tight schedule, providing a solid foundation for upcoming construction.
Drilled piling along the excavation edges
In the first phase of the project, 220 mm steel pipe piles were drilled at regular intervals along the edges of the excavation at the Kiruna site. This created a stable foundation for the pile wall, which the client finished with a sheet metal panel wall. The structure served as a base for supporting the excavation walls, enabled safe work inside the excavation, and provided a neat, compact, and visually clean construction.
Steel beams and anchoring to reinforce the wall
To support the sheet metal wall, a robust steel beam structure was installed on site, reinforced with seven 115 mm steel pipes drilled at a 45-degree angle into solid rock. Through-drilling equipment was used to achieve 3-meter-deep rock anchors, ensuring the wall remained firmly in place. This drilling equipment is particularly suited for projects requiring highly precise and durable anchoring in challenging rock formations.
Final anchoring with wire rope strand anchors
After the drilling work was completed, Juvatec Oy’s skilled team installed wire rope strand anchors into the steel pipes, which were then grouted in place to provide additional stability. Once the grout had cured, our crew tensioned the anchors to ensure the wall could withstand the imposed loads and pressures. This resulted in a straight and robust retaining wall, allowing the deep excavation to be carried out safely while protecting adjacent buildings and traffic routes.
Reliable and safe construction in challenging conditions
This drilled piling and anchoring project in Kiruna is an excellent example of Juvatec Oy’s expertise in challenging construction sites, where safety and durability are top priorities. The result was a solid support structure that enables planned construction work in the area to proceed safely and efficiently.
