Abstract
A method and a device for producing a pipe bed or a pipe bed profiling. The method includes: digging a trench, producing a trench floor, producing the pipe bed or pipe bed profiling by a pipe-bed finisher adapted in at least one sub-region of its outer contours to the outer contours of the pipe to be laid, and on its longitudinal sides at least one guide or side element projects laterally on each of its two sides. The device has a pipe-bed finisher, shape-adapted in at least one sub-region of its outer contours to an outer contour of the pipe to be laid. The pipe-bed finisher is constructed either as a pipe profiling arbor that has at least on one front end, a finished guide tip or as a pipe profiling sleeve that has a punch-like, open or closed, concave or convex sleeve end region in the advancing direction.
