FIELD: machine building.SUBSTANCE: rolled flexible plastic pipes of smaller diameter are transported to a place of laying, which are then unfolded from rolls and pulled in parallel to each other in the place of pipeline laying into a trench or along the earth surface. The quantity of pipes is selected so that the total cross section of smaller diameter pipe area sum is equal or exceeded the area of the cross section of the pipe of larger diameter required in accordance with throughput capacity. Then pipes are cemented or concreted together in the form of a pipe of larger diameter.EFFECT: simplified transportation, manufacturing and installation of pipes of larger diameter, reduced costs.1 dwg |
