OFT drillings Julianaplein Groningen

In Groningen we completed drilling 45 meters of Ø820 (steel) using the Open Front Technique last week.

We then introduced a Ø630 HDPE pipe, including spacers. Because there are spacers, the pipe is exactly in the middle of the casing tube, so the walls of the casing tube are not touched. The pipe, which is under slope (free fall), serves to drain water coming from the new car tunnel to be constructed. The sheet pile pit will remain behind because it will be used as the final pump shaft for the entire Juliana Square.
