FIELD: construction.
SUBSTANCE: method includes erection of shafts, driving a tunnel with arrangement of lining, installation of tiers of protective casings from polymer or steel pipes, their fixation against longitudinal displacement and placement of working pipelines inside appropriate protective jackets. In the tunnel they form a support surface, arranged above the lower tier of pipeline installation. On the support surface along the tunnel they install a rail track, using which, pipes of protective jackets are delivered to the tunnel. From a wagon site, using a crane-manipulator, they install onto supports at both sides from it and further weld pipes of protective jackets of the second tier. Then metal brackets are mounted around protective jackets of the second tier, using metal brackets, they install onto supports put onto them and further weld pipes of protective jackets of the third tier. After that they dismantle the rail track and install remaining protective jackets from pipes on a free space with installation of working pipelines in protective jackets. The space of the tunnel between the protective jackets is filled with sand pulp.
EFFECT: simplified process of pipeline installation.
