  • DE-U-9211801 describes a device for exchanging soil material especially known alongside traffic routes and buildings, the one formwork arrangement with two parallel, at a distance held vertical formwork walls that after Type of knife installation by ramming and / or in a previous one excavated excavation pit can be brought into the ground. Between the formwork walls is in this known device plate-shaped abutment arranged over adjustment cylinders is coupled to the formwork walls and thus their propulsion allowed in the ground.
  • This known device can in particular next to traffic routes, for example next to train tracks to find a soil exchange there.
  • Knife shields whose main area of application is tunneling, are due to their frictional engagement between the jacking knives and the principle of work based so far on the trench walls only used as a knife shoring for trenching if, as with pipe laying work, trenches of proportionate great depth must be created.
