![]() ![]() ![]() Any ground subsidence that occurs can be absorbed by the permissible deformation of the pipes without the danger of damage as a result of cracks or breaks. Given their high flexibility, wash borings with small installation radii are also possible. Pipes made from PE 100-RC are permanently resistant to corrosion from the mine water transported here. The complex repair of the damaged section would not rule out the risk of further damage to other sections around the pipe bridge.Ī new installation using the horizontal directional drilling method with pipes made from PE 100-RC was the most economic and easiest solution to implement. Thorough repairs on the existing GRP pipelines would be very time-consuming and have an excessively high impact on mining of the brown coal, which can only operate without the pipelines for a few days. Several floods in 2010, 20 in the area around the pipe bridge near Spreewitz resulted in a pipe rupture in a GRP bend in Nochten Water Pipeline. The two pipelines crossed the Spree river on a pipe bridge close to the town of Spreewitz. Two parallel underground GRP pipelines are used to transport the groundwater and mine water from the mine to the mine water processing plant. As the brown coal stratum lies below the natural groundwater table, the water table needs to be lowered. The brown coal for the the Schwarze Pumpe brown coal power station is excavated in the nearby opencast mine in Nochten. Supplied by FRANK GmbH and manufactured by AGRU Kunststofftechnik GmbH, the Dutch company Visser & Smit Hanab, as a subcontractor specialised in this method, installed the PE pipeline by applying the horizontal directional drilling process.
