Claims (1)

Способ сооружения морской платформы со сквозным опорным блоком, закрепляемым к морскому дну сваями, отличающийся тем, что опорный блок изготавливают на берегу из двух составных по вертикали секций: нижнего и верхнего ярусов опорного блока, после транспортировки нижний ярус опорного блока устанавливают на дно и закрепляют "короткими" сваями, забитыми через его основные стойки в дно до входа в плотный подстилающий слой грунта и обеспечивающими устойчивость нижнего яруса опорного блока в начальный период монтажных работ в море, а верхний ярус опорного блока устанавливают на нижний ярус таким образом, что стойки верхнего яруса опорного блока стыкуют с "короткими" сваями, после чего удаляют внутритрубную грунтовую пробку в "коротких" сваях и через них и стойки верхнего яруса забивают "длинные" сваи, несущие верхнее строение, при этом, в случае подводной стыковки ярусов опорного блока, стыковочный узел охватывают снаружи кессоном и герметизируют пакером или подводной сваркой, после чего воду из стойки верхнего опорного блока и кессона откачивают до уровня ниже стыковочного шва, который подготавливают и сваривают изнутри стойки автоматической электросваркой в нормальных атмосферных условиях, при большом диаметре стойки электросварку выполняют сварщиком, размещенным на плавучем понтоне, который опускают и поднимают в стойке путем удаления или подачи в нее забортной воды; при этом после забивки и соединения "длинных" свай со стойками верхнего яруса опорного блока межтрубное пространство свай, стоек и кессонов заполняют цементным раствором.A method of constructing an offshore platform with a through support block fixed to the seafloor by piles, characterized in that the support block is made on the shore of two vertical sections: the lower and upper tiers of the support block, after transportation, the lower tier of the support block is installed on the bottom and secured " short "piles, hammered through its main racks into the bottom before entering the dense underlying layer of soil and ensuring stability of the lower tier of the support block during the initial period of installation work at sea, and the upper The support block mustache is installed on the lower tier in such a way that the uprights of the upper tier of the support block are joined with the "short" piles, after which the in-tube earth plug in the "short" piles is removed and the "long" piles carrying the upper structure are hammered through them and the upper tier racks in this case, in the case of underwater docking of the tiers of the support block, the docking assembly is covered outside with a caisson and sealed with a packer or underwater welding, after which the water from the rack of the upper support block and caisson is pumped to a level below the docking seam , which is prepared and welded from the inside of the rack by automatic electric welding in normal atmospheric conditions, with a large diameter of the rack, electric welding is performed by a welder placed on a floating pontoon, which is lowered and raised in the rack by removing or supplying outboard water to it; in this case, after driving and connecting “long” piles with uprights of the upper tier of the support block, the annulus of piles, racks and caissons is filled with cement mortar.
