Погружают трубопровод в следук исй носледовательности . Устанавливают нп дно водоема анкера 3 с закрепленными к ним неподвижными блоками 4, и пропущенным сквозь блоки 4 тросом 5. Трос соединен с береговым анкером в и лебедкой 7, Но участках между анкерами 3 трос 5 ослабл ют и временно креп т к поплавкам на поверхности водг, После сварки трубопровода 1 в одну нитку и закреплени  на нем подвижных блоков 2, трубопровод опускают на воду, подгон ют к поплавкам, навешивают на блоки 2 трос 5. Лебедкой 7 выбирают слабину троса 5 и погружают трубопровод 1 до нужной отметк Предлагаемый способ укладки позвол ет равномерно погружать трубопровод по всей его длине, выравнивает напр же ш  в его сечени х, снижает усили  нат жени  анкеро и троса по участкам, уменьшает вли ние неровностей дна. Если отдельный участок трубопровода достиг анкера ранее других, то по мере выбирани  троса лебедкой продолжают погружатьс  остальные участки. Скорость пс  ружёни  трубопровода регулиру с  оборотами лебедки, усилие в тросе числом анкеров и блоков; число анкеров предол етс  их конструкцией и свойствами -рунтадно водорма. Способ обеспечивает возможность укпдки трубопровода любых диаметров на лубину ит уровн  воды до 100 м и более при значительных скорос;т х водного потока, Формула изобретени  Способ укладки трубопровода на дно водоема , включающий установку на дно водоема анкеров с неподвижными блоками и пропущенным через них тросом, размещение трубопровода на поверхности воды, погружение трубопровода на дно путем нат жени  троса, отличающийс  тем, что, с целью упрощени  производства работ, перед погружением трубопровода на нем закрепл ют подвижные блоки, а трос пропускают поочередно через каждый подвижный и неподвижный блоки. Источники информации, прин тые во вни мание при экспертизе: 1.Авторское свидетельство СССР № 109120, кл. Е 02 D 29/О6, 1956. Immerse the pipeline in the track of the line. Install the bottom of the reservoir of the anchor 3 with fixed blocks 4 fixed to them, and cable 5 passed through the blocks 4. The cable is connected to the shore anchor in and winch 7, but the areas between the anchors 3 cable 5 are weakened and temporarily attached to the floats on the surface After welding the pipeline 1 in one line and fixing the movable blocks 2 on it, the pipeline is lowered into the water, the float 5 is fitted to the floats, the cable 5 is hung on the blocks 2. The winch 7 selects the slack of the cable 5 and immerses the pipeline 1 to the desired mark em rav numerically immerse the pipeline along its entire length, aligns the stresses in its cross sections, reduces the tension of the anchorage and cable along sections, reduces the effect of bottom irregularities. If a separate section of the pipeline reached the anchor earlier than others, then as the cable is selected by the winch, the remaining sections continue to be immersed. I adjust the speed of the pipeline control with the winch speed, the force in the cable by the number of anchors and blocks; The number of anchors is given by their design and the properties of a soil-hydrated soil. The method makes it possible to install a pipeline of any diameters per lip and water level up to 100 m or more at significant speeds, water flow, the invention The method of laying the pipeline to the bottom of the reservoir, including installing anchors with fixed blocks to the bottom of the reservoir, placing the pipeline on the surface of the water, immersing the pipeline to the bottom by pulling the cable, characterized in that, in order to simplify the work, before the pipeline is immersed, movable blocks are fixed on it ki, and the cable is passed alternately through each movable and fixed blocks.
