Abstract
A method and device for shoring trenches includes insertion of a first couple of lining plates into a ditch. A stiff bracing frame may be guided within a first couple of linear guides between the two lining plates, one linear guide being connected to one lining plate. A second couple of lining plates may be guided between the first lining plates and inserted into the ditch. A second couple of linear guides may be inserted between the first linear guides, one of the second linear guides being connected to one of the second lining plates, and the second linear guides being kept at a distance using a brace. The bracing frame between the first linear guides may be removed, and the second lining plates and the second linear guides may be lowered while the stiff bracing frame is inserted between the first linear guides when the ditch is dug deeper.
