Illingen-Wustweiler Sammler 1.0
Sharp curves in the sewer
This advance was quite challenging for our navigation system SLS Microtunnelling LT. Due to a sharp S-curve with a radius of 150m and 120m at an advance length of 270m, the conditions were very difficult. In addition, the work has been hampered by the small diameter of 1.6m. The excavation lasted 4 months.
