Pipeline Crossing In A Single Step

摘要

In the fall of 2016, drilling contractor PPI Chrobok S.A installed two new gas pipelines in Poland. The alignment, which runs along existing gas lines and through geologically challenging terrain, marked the first use of Herrenknecht's Direct Pipe technology in Poland. With the construction of a new north-south pipeline connection, Poland is reacting to the increasing local demand for gas. Part of this network expansion is the Cze-szów-Wierzchowice Gas Pipeline Project in the southwest of the country. For some time, only horizontal directional drilling (HDD) has been used for crossing rivers or roads during pipeline projects in Poland. Used for decades, the method has proved its worth for large numbers of boreholes, but it reaches its technical and economic limits in heterogeneous, non-stable grounds.
