FIELD: pipeline transport.
SUBSTANCE: invention relates to pipeline transportation field and can be used for construction of pipeline crossings over natural obstacles, rivers, ravines. Single-span pipeline crossing comprises bank piers and anchors. Bank piers are made of bearing and thrust bearing elements connected in their upper part in pairs, and installed on inclined support plates. Support plates arranged in natural obstacle slope upper part and rigidly connected with mating anchor plates, equidistantly arranged on pipeline axis both sides and fixed on horizontal surface adjacent to natural obstacle slope edge. Pipeline is arranged in side beds and in central bed. Side beds are attached to thrust bearing elements. Central bed is connected with pillars with help of suspensions, rigidly fixed in each bank pier upper part. Bank piers and suspensions form angles with pipeline axis, sufficient to compensate for side wind loads on pipeline.
EFFECT: increasing covered span length in case of natural obstacle complex shape and higher crosswise stability of pipeline inter-support part.
