Implementation of trenchless projects in complex gravel formations – feasibility study of Direct Pipe crossings.

During the presentation the Direct Pipe projects implemented by PPI CHROBOK S.A. technology will be analysed. Drilling in Serbia under the Vielika Morava river and in the vicinity of Nowy Targ under the Białka river was characterized by complex geological conditions in the form of gravels and pebbles. Direct Pipe as a modern technology for the construction of pipelines works in such conditions reducing the risk of an unstable borehole and maintaining circulation of drilling mud.
