STATIONARY PIPELINE SUPPORT

The claimed invention relates to the field of above-ground pipeline construction and can be used in the organization of pipeline supports in difficult geological conditions, such as in conditions of permafrost. The technical result achieved by using the claimed invention consists in providing for the stability of a structure and in redistributing loads from a pipeline to a pile foundation. The aim is achieved in that a stationary pipeline support includes a coil which is mounted, by means of electrically-insulating assemblies, onto four stands which are height-adjustable so that the height and incline of the support can be adjusted, and which are secured on a single-level grillage foundation which rigidly rests on a pile foundation. The coil is in the form of a pipe which is provided with an outer casing and with a layer of thermal insulation; the pipe has an inner tubular shell affixed at the central portion thereof; longitudinal ribs are rigidly affixed to the shell, thus allowing the coil to be secured to the stands; the stands are secured to the grillage foundation by means of support flanges. The load-bearing structure of the coil, and the principle behind and way in which the coil rests on the stands, make it possible to prevent axial and lateral displacement of a pipeline, and permit transfer of a load born by the coil to the grillage foundation of the support by means of brackets with electrical insulation, with adjustable stands and a pile foundation. L'invention se rapporte au domaine de la construction de conduits en surface et peut être utilisée lors de l'édification de supports de conduits dans des conditions géologiques difficiles, comme en cas de gel permanent. Le résultat technique de la présente invention consiste en une structure solide et une redistribution des charges du conduit sur les fondations de pylône. Ce but est atteint grâce à un support immobile de conduit comprenant une cartouche disposée via des unités d'isolation électrique sur quatre montants capables d'ajuster leur hauteur afin d'ajuster la position en hauteur et l'angle d'inclinaison du support, et fixés sur une cage de même niveau et reposant fermement sur les fondations de pylônes. La cartouche consiste en un tube comportant un capot externe et une couche d'isolation thermique à laquelle est fixé, dans la partie centrale, un anneau interne auquel sont connectées rigidement des arêtes longitudinales permettant de fixer la cartouche aux montants. Les montants sont fixés
