Strand Anchors Stabilize Supporting System against Water Pressure
Since 2006, the B 15 new federal road has been under construction in Germany. Once fully completed, the 130km project will lead from Regensburg to Landshut and on to Rosenheim.
Currently, the section between Ergolsbach and Essenbach is being built. This section has a length of 9km and includes 13 structures. Each of the two lanes will have a width of 10m. The largest engineering structure in this section is the 1,000m long basement waterproofing near the town of Ohu.
The high groundwater table poses a challenge during the construction of this structure. Furthermore, traffic on the A 92 may not be obstructed during construction work.
For the basement waterproofing, sheet pile walls had to be erected that were tied back using temporary DYWIDAG Strand Anchors to resist the water pressure in the jobsite area. During the drilling work, water was encountered 2m above the first anchor layer. To stabilize the supporting system against water pressure, DSI Germany supplied 20,000m or 1,370 pieces of 4-7 strand temporary DYWIDAG Strand Anchors.
