Method and device for production of a pipe bed

A method for production of a pipe bed comprising the following steps:

• a) digging of a trench,
• b) producing a trench floor,
• c) producing a pipe bed or pipe bed profiling using a pipe-bed finisher (7) having a shape in at least one sub-region of an outer contour thereof that corresponds to an outer contour of a pipe to be laid, wherein for digging a pipe trench floor (4), using a digger attachment that performs, from the following work steps:
• digging the trench (3), production of the trench floor (4) and production of the pipe bed or pipe bed profiling, at least one work step in a coordinate-controlled manner using a coordinate or satellite global positioning system (GPS) measurement and control unit, and wherein the pipe trench floor (4) is produced by a coordinate or satellite (GPS) sensor (5) installed on the digger attachment according to at least one of a height, alignment, or gradient according to specified coordinates or GPS signals, and wherein the pipe-bed finisher (7) is guided through a pipe-bed material (6) in a plowing manner with coordinate or satellite (GPS) control, such that the bed material (6) is planed, extracted, and simultaneously compressed by the pipe-bed finisher (7), wherein after production of the trench floor, at least one part of excavated soil and/or soil sitting on the trench floor is processed and used in the trench as pipe-bed material.
