V., Registration Date 10-02-2003 Organization The Odessa State Akademy of Building and Architecture popup.description2 In the work existing methods of laying of underwater pipelines of a large diameter are considered and technical complexity of their erection when it's necessary to provide the outlet of pipeline dischrges on ecologically safe depthes is shown.The new technique of calculation of pipelines immersion considering the application of tensile stresses and inclusions in their construction of hinged insertions for elimination of excessive stresses is developed. A complete cycle of the system of underwater pipelines with the following operational processes is considered: manufacturing, lowering to water and towage to the place of laying , installation in the fold of the line, immersion of separate pipes with docking them above water, arrangement of the anchorages of floating facilities. Specific kind of the pipeline construction mostly conceming the branch of municipal economy is considered therein, namely: superlong-distance marine discharges of waste water from steel pipes of a large diameter. The immtrsion of water discharges on the bottom of a basin is carried out without application of uneconomical and hard diving labour. A large cycle of experimental researches for various depthes of a basin with application both continuous constructions and dismembered by hinged insertions is conducted. Accordig o the offered technique calculations of experimental pipelines shown good convergence of theoretical and experimental results have been made.
