Abstract

In a method for setting up a pipeline section of a pipe system in a heat network, which is provided for transferring a heat transfer fluid between a heat provider and a heat consumer, the pipeline section is subdivided into segments in a segmentation step. A segment characteristic variable is determined for each segment based on a physical soil characteristic variable. The determined segment characteristic variables of two adjacent segments differ by more than a predefined segment characteristic variable difference value. In a bedding determination step, segment embedding of a pipeline segment, introduced in the trench in this segment, in a water-permeable segment bedding material is predefined for each segment such that a heat loss of the heat transfer fluid transferred in the pipeline segment, which is averaged over the segment and is based on a unit of length, is lower than a predefined heat loss limit value.
