Abstract (en)
[origin: EP2722443A1] The method involves fastening an inner linear guide (13') at an outer linear guide during lowering the outer linear guide into deep trenches such that lower ends of the inner linear guide are provided in a distance above next-lying lower ends of the outer linear guide. The inner linear guide is released from the outer linear guide and lowered upto a bottom of the trenches after lowering the outer linear guide into the trenches. The inner linear guide is lowered, and a spreading frame (3) is inserted between the outer linear guides during digging the trenches. An independent claim is also included for a device for shoring deep trenches.
