Jack-up platform leg and ocean platform with the same

Abstract

The invention provides a self-elevating platform pile leg and an ocean platform with the same. The pile leg comprises a hollow columnar pile leg body, a separator and at least one communicating part, a group of pin holes are circumferentially formed in different positions of the pile leg body along the height direction, the separator is mounted at a set position in the pile leg body, the shape of the separator is matched with that of an internal section of the pile leg body, the internal space of the pile leg body is divided into an upper cavity and a lower cavity which are mutually independent, the communicating parts are mounted at the pin holes in the lower cavity in a one-to-one corresponding manner and provided with a group of mutually communicated openings, and the openings of each communicating part are fixedly connected with the inner wall of the pile leg body and communicated with the pin holes in a one-to-one corresponding manner, so that the pin holes are communicated with each other and isolated from the lower cavity. Insertion and extraction operations of pins cannot be affected, soil cannot enter the pile leg, and pile extracting difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of ocean engineering, in particular to a jack-up platform leg and an ocean platform with the leg. The leg is suitable for matching with a hydraulic bolt-type lifting system. Background technique [0002] The legs are a very critical part of the jack-up platform. They are used to support the weight of the upper hull and withstand environmental loads such as wind, waves, and currents. Their structural forms are mainly cylindrical legs and truss legs; The lifting system mainly includes hydraulic pin type and rack and pinion type. For the hydraulic plug-type cylindrical pile legs, there are many square holes or round holes for the bolts on the pile legs. When the pile legs are inserted into the seabed soil, the soil enters the pile legs from these holes due to the existence of the holes, which leads to The following problems: on the one hand, the weight of the pile leg is increased, which increases the difficul...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-elevating platform leg and an offshore platform with the leg, which solves the problems in the prior art that the pile is difficult to pull out due to soil entering the leg and the soil is difficult to clean
