Overview

In the course of the years, Robit Rocktools Ltd has been involved in several Olympic Games building projects all around the world. The work will continue with the next Winter Olympics in Sochi, as the local contractors rely on Robit products for digging the tunnel network – a necessary part of the game venue infrastructure.

The 2014 Olympic Games will be organized in Sochi, the first Winter Olympics to be held in Russia. To ensure smooth transport between the various sites, a tunnel network with a total length of over 26 kilometers is being excavated in the area. One of the key factors behind Sochi’s selection as the Olympic City was the creation of a functional road and railway network, and Robit has its share in this.

Several contractors in Sochi are utilizing the Robit RoX+ 88.9/8 Top Hammer system in tunnel work. The system consists of a pilot bit automatically locking with a ring bit, which makes work considerably easier and faster. “Word about the excellence of our product quickly got around the Sochi sites, and a total of six contractors started using it”, says Oleg Ivanov, Regional Manager at Robit Rocktools Ltd.

“Our co-operation went smoothly. The contractors appreciated our proactive technical support and service. We were able to respond to their wishes comprehensively,” Ivanov continues. Work on the Sochi tunnel sites is getting near completion. “We will continue by delivering our HTG bits to the Olympic sites as needed.”

Metro heads to the west with Kalliorakennus and Robit

Overview

The challenging construction work of the new, westbound metro line in Helsinki demands wide-ranging expertise. Drilling maintenance shafts for metro tunnels has little room for error, but Kalliorakennus-Yhtiöt ensured a successful end result by using Robit products.

The metro tunnel shafts are a vital part of the underground railway system. They serve as emergency exits, smoke vents and pressure equalization as well as ventilation systems. Among their other large contributions to the West Metro construction, Kalliorakennus-Yhtiöt had to drill 44 meter-deep shafts with a surface area of 68 square meters to solid Scandinavian bedrock – by no means a trivial task.

“We set tough quality requirements for the project, as the work outcome must be exact. We drilled the excavation holes for the shaft from the top right down to the bottom, whereas drilling is normally carried out from both the bottom and the top. It was crucial that the holes turned out straight,” explains site manager Martti Kähkönen from Kalliorakennus. “We used Robit Rocktools special equipment to make sure the drilling holes were straight”.

The collaboration between Kalliorakennus and Robit go back since the early ‘90s. “All of the bits we use are from Robit, because they are familiar products for me. I participated in the bit development work for the first time many years ago”, Kähkönen recalls. In addition to the shared history, Robit’s wide service offering has also impressed Kalliorakennus. “Robit is a reliable partner, but their bit-sharpening service was also a major reason behind why we chose them as co-operation partner in the West Metro project,” he says.
