Piling without disturbing the neighbours in Stockholm

Posted on by admin

Overview

Solna Arenastaden right next to Solna railway station needed support piles for passage over railway between Arena and surrounding buildings. The urban site called for extra care and Robit products.

The work site needed some 150 piles (220/12.5) to be driven to overburden ground, which tends to ”suck the water” due to numerous fractions. What’s more, there was a large sewage passing near the worksite, let alone railway and buildings. In this environment, any pollution would be no-no as well.

Due to ground type, air drilling would almost surely cause problems to surroundings. The use of Wassara W150 ensured fast penetration and created less noise. The project was finished with minimum disturbance.

New Robit horizontal drilling equipment proves its worth in Sweden

Posted on by admin

Overview

Robit, in collaboration with our retailer Swedish retailer GDS Sverige AB, put our new HZ product series to test under a motorway ramp near Landvetter airport.

Robit has been developing the new HZ series for horizontal drilling in Sweden since the early 2011. Now, the new system was put through its paces under a motorway ramp, where a 24-meter hole of size 406.4/12.7 was drilled. The land filling under the ramp consisted partially of very large boulders. Because of the boulders and directional requirements, the drilling was a challenging test to our new HZ series.

Despite the rough terrain, the results proved successful. No problems occurred, and the drilling went as

planned. What’s more, the test drilling results have enabled the company to further improve the functionality of the HZ product line.
