Some theoretical sides of calculation of temperature deformations of underground heat conductors

In this article we examine the process of thermal deformations of trenchless pipe network. Distribution of heat stress was analyzed for trenchless parts under different variants of positioning of U-shaped compensators inside compensator recesses and the most effective scheme is shown. Calculation and sustainability check algorithm was explored concerning starting compensator for trenchless part. Diagrams presented, which show dependency of maximum length and stabilizing vertical load from depth of fi ll.
