FIELD: transportation; construction.
SUBSTANCE: invention relates to main pipeline transportation of liquids and gases and can be used during earthworks in the process of preparation for repair, as well as directly during the repair of small-length sections of underground pipelines layed in swampy areas, where the level of ground waters does not allow to perform repair work without a preliminary preparation. Technological complex for opening of a section of an underground pipeline includes an excavator, at least two floorings and sheet piles, the number of which is determined based on the overall dimensions of the developed pit. Floorings are made of tightly welded pipes. For movement of floorings around the developed by the excavator pit, metal lugs are welded on floorings. Sheet piles are made of segments of pipes welded together by a single-stranded weld seam and reinforced by means of straps. In the upper part of every sheet pile sheet metal is welded by a single stranded non-continuous welding seam.
EFFECT: wider range of equipment.
