A high-efficiency controllable jack-up platform spud shoe device

Abstract

The invention discloses an efficient controllable self-elevating platform pile shoe device, and belongs to the field of ocean engineering auxiliary equipment. The efficient controllable self-elevating platform pile shoe device comprises a shoe frame, a pile leg tube sleeve, a hydraulic type locking torsion bar, a built-in rotatable blade and an ultrasonic probe. The efficient controllable self-elevating platform pile shoe device is characterized in that the hydraulic type locking torsion bar is arranged in the pile leg tube sleeve, and connected with the built-in rotatable blade, the built-in rotatable blade is installed in the shoe frame, the shoe frame is installed at the bottom of the pile leg tube sleeve, and the ultrasonic probe is arranged on the upper portion of the shoe frame. The built-in rotatable blade is composed of a plurality of fan-shaped plates. The efficient controllable self-elevating platform pile shoe device has the advantages that the area of contact between a pile shoe and a foundation is reduced through a pierced frame mode in the process that a pile is installed and inserted into a self-elevating platform, friction is reduced, and the effective piling depth is achieved.

Description

Technical field [0001] The invention relates to an efficient controllable self-elevating platform pile shoe device, which belongs to the field of marine engineering auxiliary equipment. Background technique [0002] With the increase in the development and utilization of marine resources, the scale of the development of modern pile-legged offshore platforms has become larger and larger, and a large number of offshore platforms (especially large jack-up offshore platforms) have gradually been applied to deep waters such as the East China Sea and the South China Sea. Since the pile boots of many jack-up platforms still use the circular or polygonal disc surface form of the previous pile boots, the depth of mud entry when the platform legs are installed is relatively shallow, the mobility is not strong, and the foundation is often damaged. The phenomena of stability, uneven settlement of pile legs, platform tilt, scouring and scouring, resulting in unstable platform structure, which...

AI Technical Summary

Problems solved by technology

[0004] The problem to be solved by the present invention is that the self-elevating offshore platform can work on various seabed silt foundations by inserting piles and installing fixed platforms, and can well overcome the stability of the pile force legs of the offshore platform caused by different sea area conditions. , the adverse effects of the floating state, and the self-elevating platform can be easily pulled out and moved after the resource mining work is completed
