SUPPORT OF HEAVY LOAD PIPELINE Russian patent published in 2015 - IPC E02D27/46 

FIELD: construction.

SUBSTANCE: invention relates to structures of supports for heavy load pipelines. The support of the heavy load pipeline comprises a foundation block, a pipeline and a foundation support parts with assemblies of longitudinal and transverse temperature movements with sliding surfaces. Assemblies of temperature movements additionally comprise an upper spacer fixed on the support part facing the pipeline, and a lower spacer fixed on the support part facing the foundation. Spacers are made on the basis of a ultrahigh molecular polyethylene with molecular weight of more than 2 million carbon units with addition of 2-5 % of either titanium dioxide or molybdenum disulphide, or 5-8 % of carbon. Spacers are equipped with garbage collection grooves on the sliding surface, arranged at the angle from 30 to 60 degrees in respect to the direction of movement.

EFFECT: reduction of the level of stresses and dynamic loads in pipelines and supports in case of shift processes.
