METHOD OF PIPELINE LAYING ON THE BED OF WATER BODY Russian patent published in 2018 - IPC F16L1/16 F16L1/20 F16L1/06 

FIELD: instrument engineering.

SUBSTANCE: invention relates to methods of pipeline laying along the bed of water bodies. Method of pipeline laying along the bed of water bodies involves laying the pipeline on the joint piles that are previously fixed on the bed of a water body in a single row, followed by fastening with clamps. Joint piles consist of screw piles with additional threaded part and removable extensions. Screw piles are drilled into the ground using removable extensions, which also used to provide the required orientation of the buoyant pipeline before it is flooded. Additional threaded part of the screw piles is used to fix the pipeline at a given depth with the help of upper and lower half-clamps with a locking system, as well as supporting and fixing nuts.

EFFECT: method ensures safe work while pipeline laying, the possibility of adjusting the sag, the ability to adjust the level of stress-strain state, the possibility of full visual inspection of the pipeline, the minimum labor costs for securing the pipeline on the supports.
