PIPELINE COMBINED LAYING METHOD Russian patent published in 2008 - IPC F16L1/28 

FIELD: transportation.

SUBSTANCE: sections of an overhead, surface and underground pipeline laying are selected on the route being developed. The overhead pipeline supports are located directly on the ground base surfaces and the support lower parts are top filled with soil. At the points of transfer from one type of laying to the other one, the pipeline is laid in a vertical plane along the curve with a minimum elastic bend radius, allowing for a tolerable bending strength, while, in plan, it is laid with an elastic bending and locating turn apexes at the centre of every selected route section.

EFFECT: higher industrial and ecological safety in pipeline operation.
