A remotely operable drilling apparatus drills annular piles into the seabed using a power swivel and rack-and-pinion drive system.
Dynamic lifting and lowering cycles using a pivoting ripping tool break up channel walls to redistribute existing soil material without external additives.
High-pressure water jetting disturbs sand layers around pipe piles to reduce soil resistance during driving operations.
Segmented sleeve and interlocking fittings distribute torsional loads, preventing side hole elongation and weld failure during installation.
Telescoping screws and wing blocks allow vertical and lateral adjustment, resolving installation misalignments without permanent concrete pouring.
Composite pile recesses enclose mortar at angles exceeding 90 degrees to transmit shear forces between structural components.
An inclined spiral blade guides soil to the helical plate, resolving the trade-off between complex geometry and universal soil adaptability.
Segmented pile connections replace concrete footers by allowing horizontal beam mounting, reducing installation time and site disruption.
