Three-zone principle. The screw starts with a feed zone: Constant depth, takes up 15 to 30% of length. In the middle is the compression zone, walls close in on the melt/pellet mix, drive air backward and make up for slipping and rolling of pellets in the feed zone. This zone contains the "barrier" of barrier screws: A long double-channel ...

Pipe Express®
Pipe Express ® is a mechanized method for the near-surface installation of pipelines in semi-trenchless construction. The technology is suitable for pipelines with diameters of 900 to 1,500 millimeters and distances of up to 2,000 meters. A TBM loosens the soil, which is then transported directly to the surface via an attached trenching unit.
