Underwater passage of an oil pipeline with a diameter of 820 mm across the river by the method of directional drilling
Description
Underwater passages can be placed relative to the natural surface of the bottom of reservoirs in several ways: on the bottom; hanging structure above the level of the bottom; below the level of the bottom. Trenchless methods of laying pipelines are a more promising and new direction: these methods are environmentally friendly, often less time-consuming than trench methods.
