Method and device for production of a pipe bed

摘要

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.

1. 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.
