Title:
GRAVITY PILE SHOE CAPABLE OF BEARING LATERAL LOAD EFFECT
Document Type and Number:
WIPO Patent Application WO/2023/169244
Kind Code:
A1
Abstract:
The present invention relates to a gravity pile shoe capable of bearing a lateral load effect, comprising a mounting base, an anti-lateral motion portion and a pressure reducing portion. The mounting base is assembled at the lower free end of an offshore platform pile leg. The anti-lateral motion portion is formed from multiple inserting columns which are directly borne by the mounting base and may be deeply inserted below a seabed bearing layer. The pressure reducing portion comprises a top contact bottom plate and an auxiliary connecting unit. The top contact bottom plate is arranged parallel to and directly below the mounting base, and a clearance gap allowing an inserting column to freely pass through is provided on the top contact bottom plate. The auxiliary connecting unit is formed from multiple sets of linkage mechanisms which are connected between the mounting base and the top contact bottom plate, and are uniformly distributed around the periphery of the anti-lateral motion portion. After the offshore platform pile leg completes final sinking construction, the inserting column is deeply inserted into the bearing layer, so that the pile shoe has good lateral force resistance, thereby ensuring that the ocean platform meets the requirements for resisting horizontal impact loads, which means that the risk of lateral motion is reduced when it is subjected to a series of horizontal loads such as wind, waves, and ocean currents.
