METHOD FOR ERECTION OF UNDERGROUND PIPELINE AT CROSSING OF TECTONIC FRACTURES

摘要

FIELD: construction. ^ SUBSTANCE: invention is related to construction and may be used in underground installation of pipelines that cross zones of tectonic fractures. In method for erection of underground pipeline at crossing of tectonic fractures, locating blocks are fixed in pneumatic springs installed on axis of trays symmetry along pipeline length with pitch equal to pitch of pipeline stands installation, with the possibility of compressed air supply to them via air ducts. After pipeline installation, remaining space is filled with easily deformable material. Height of pneumatic springs in filled condition and gaps between pipelines and trays are accepted as higher than value of maximum possible predicted displacement of pipeline. ^ EFFECT: application of this method for erection of underground pipeline at crossing of tectonic fractures provides for the following advantages: improved efficiency; reduced labour intensiveness of installation; reduced labour intensiveness of maintenance. ^ 3 cl, 1 dwg
