SUSPENSION SUPPORT FOR SECTIONS OF UNDERGROUND PIPELINE ROUTING

摘要

FIELD: construction.SUBSTANCE: invention relates to construction of underground pipelines under permafrost conditions. Suspension support comprises movable and fixed parts connected by flexible chain suspension. Movable part comprises a lodgement in form of a semi-cylinder with semi-annular frames on outer side. Pipeline in lodgement is fixed by detachable half-yoke. Fixed part of support includes a foundation frame, made in form of interfaced beams, bridges and stiffness ribs arranged on top bearing plates. Foundation frame is fixed on pile foundation through support assemblies of hinge type. Chain suspension is articulated with one end with lodgement and at other end with adjusting screw resting through support washers and nuts on support plate of foundation frame. Additionally, on pipeline is fixed a band of two half-shells installed on pipeline via safety cushioning material representing rocky sheet. Pile foundation is double-pile or four-pile.EFFECT: restriction of movement of pipeline and providing within preset limits displacement in longitudinal, transverse and vertical directions upward at temperature deformations of pipeline and under effect of maximum loads on support of pipeline.5 cl, 5 dwg
