Abstract RU 2227856 C2

FIELD: pipelines construction technology. SUBSTANCE: method includes tearing away of mounting pits for baring whole surface of metallic pipeline, pipeline cutting with prior terrain ripping under pipeline and drawing a snell under the pipeline. Slanting chute is formed during dismantling, certain portions of which are later stretched by means of constantly acting horizontal force of traction device. Device has traction device with terrain ripping tooth, snell, end cap, engaging device and cable. Terrain ripping tooth is provided with expander capable of forming of slanting chute during dismantling of metallic pipeline. Snell has cable loop with rotating globe ripping means. EFFECT: lessened amount of earth work operations. 2 cl, 6 dwg
