FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to development of oil and gas deposits and can be used for anchoring of mining equipment at sea bottom. Proposed method comprises fitting the pile anchor in place by screwing the cylinder in soil, well drilling via wellhead, lowering of reinforced well casing in the well and cementing the string inner space. Note here that casing pipe is pre-furnished with lengthwise sawcuts. Prior to cementing of casing string, charge is lowered to 1.5-2.0 m from well bottom to explode its so that inverted plume is formed in the area if sawcuts as well as cavities in soil to be filled with concrete.
EFFECT: higher reliability of retention.
