Double-truncated-cone type pile shoe

Abstract

The invention discloses a double-truncated-cone type pile shoe. The double-truncated-cone type pile shoe comprises a casing, reinforcing ribs arranged in the casing and a shoe cover connected with the upper end of the casing. The casing is composed of at least two inverted hollow truncated cones from top to bottom, wherein the upper truncated cone is provided with a coaxial central hole with the diameters tapering from top to bottom, and the lower truncated cone is in a bucket shape, the diameter of the mouth of the bucket is identical to the aperture of the small-diameter central hole of the upper truncated cone, and the mouth of the bucket is connected with the small-diameter central hole of the upper truncated cone; the end surface where the upper truncated cone and the lower truncated cone are connected is provided with a truncated cone shoulder which is provided with a plurality of ring grooves; a plurality of straight grooves are distributed on the circumferential surface along the radial direction from the center of the truncated cones; the bottom of the bucket of the lower truncated cone is provided with at least one ring groove; the circumferential surface of the upper end surface of the upper truncated cone, which is close to the edge of the upper truncated cone, is evenly provided with three holes for mounting chord members of a pile leg. The double-truncated-cone type pile shoe improves the compression-resisting capacity of the pile shoe and meanwhile has the advantages of lateral sliding resistance and ocean current scouring resistance.

Description

technical field [0001] The invention belongs to the technical field of offshore platforms, and relates to a spud can, more particularly to a double-cone-shaped spud can for jack-up platform pile legs, which is suitable for seabeds in various complex environments. Background technique [0002] The spud shoe is a structure used on the jack-up platform. A spud shoe is fixedly connected under each leg of the jack-up platform, which is similar to an enlarged "discus" and supports the entire platform together with the legs . Due to the mechanical independence between the spud cans of the platform, the platform supported by the spud can adapt to various seabed conditions compared with the platform supported by the ground (sinking pad), such as: operating on uneven seabed or slightly inclined sea area . Various jack-up drilling platforms and drillships need to operate in various complex sea conditions. Since the spud cans play a fundamental role in supporting the platform, the des...

Problems solved by technology

However, the strip mechanism cannot give full play to the bearing capacity of its functional area, and the open hydraulic mechanism is under the seabed, so its reliability cannot be guaranteed. Therefore, there are still technical problems that need to be solved in practical applications
