Technique of assessing the minimum laying depth of the initial site of sewer pipelines in severe climatic conditions
The paper proposes new parameters (protection time and restoration time) regulating actions of the staff at operation of sewer pipelines of underground laying during the winter period in case of an emergency failure of movement. There is presented a calculation technique for determining the protection time in dependence of the minimum laying depth value, taking into account the pipe`s diameter, transported water temperature and frozen soil temperature.
