METHOD OF ERECTION OF VACUUM PILES Russian patent published in 2024 - IPC E02D27/52 

FIELD: construction.

SUBSTANCE: invention relates to methods of erection of piles, in particular at the bottom of water areas, and can be used in the construction of anchor piles for fixation of floating oil and gas drilling platforms, during operation of various float devices, which remove energy of sea waves, and as anchors of floating facilities, it is intended for use in hydraulic engineering and navigation. Method of erection of vacuum piles includes vertical arrangement of pipes with a plugged upper part at the bottom of the water area, pumping water from the pipes with creation of a vacuum inside the pipes and penetration of the pipes into the bottom soil by the force of atmospheric and hydrostatic water pressure acting on the plugged part of the pipes. Several pipes are placed vertically parallel to each other at the bottom of the water area; helical ribs are attached to the outer surface of each pipe. Pipes are buried in bottom soil with their rotation around vertical axis, caused by availability of helical ribs. After submersion, the pipes are rigidly connected to each other with a bridge to prevent their rotation in the opposite direction when a pulling load is applied to the pipes.

EFFECT: increased stability and reliability of vacuum piles-anchors operation in bottom soil due to increased resistance to pulling of piles from bottom soil.
