METHOD TO BUILD COMPLEX OF PIPELINES Russian patent published in 2013 - IPC F16L1/28 E03F3/06 H02G9/06 

FIELD: construction.

SUBSTANCE: in the method stiff blocks with longitudinal pockets are installed and connected to each other in a trench with the possibility of low axial and angular motions. Further different pipelines and cables are installed in appropriate longitudinal pockets. Shape and size of pockets due to the difference in the shape and size of pockets and pipelines provides for the possibility of self-installation of pipelines and cables in accordance with deformations caused by soil settling, temperature and pressure in each pipeline. Then open sides of pockets are closed by side walls with installation of their lower parts into longitudinal slots of stiff blocks. On top the blocks and walls are closed with sectional covers. Places of joints between stiff blocks, side walls and sectional covers are additionally closed with joint-to-joint covers to form labyrinth locks.

EFFECT: provision of structure integrity, prevention of soil and moisture ingress into longitudinal pockets, fixation of pipelines and cables in appropriate pockets, their mechanical safety, heat and sound insulation along entire length of pipeline routing.
