METHOD FOR ERECTION OF PIPELINES Russian patent published in 2010 - IPC E02F5/18 

FIELD: construction.

SUBSTANCE: invention relates to underground construction, in particular to methods for installation of pipelines under natural and manmade obstacles, also under water barriers designed for transportation of various working mediums. Method for erection of pipelines, in which shafts are arranged, besides as pipeline is erected under natural or manmade obstacles, shafts are erected outside this obstacle. Tunnel is driven with arrangement of lining, afterwards protective shell is laid, fixed against longitudinal displacement, and pipeline is installed inside protective shell. In driven tunnel guide tracks are preliminarily arranged along the whole length by number of protective shells arranged in tunnel. At least two protective shells are laid on according guide tracks. Afterwards working pipelines and/or cable is laid inside them, space is filled between tunnel and protective shells by filler. Besides protective shells are arranged in the form of polymer or steel pipes, which are laid in tiers, and in each tier - in rows. At the same time support surface is shaped in inner space of tunnel, arranged over lower tier of pipeline laying, for arrangement of guide tracks in upper tier of pipelines laying.

EFFECT: expansion of functionality and cost-effectiveness of the method, besides makes it possible to perform repair works and to fully replace the pipeline.
