Abstract
The utility model relates to a stepped anti-settling pile leg of an ocean platform, which comprises a pile leg, a ribbed plate, a stepped ring, transition segments and annular metal rings, wherein the ribbed plate is welded between the pile leg and the stepped ring and used for relieving stress concentration; the stepped ring is formed by welding and superimposing a plurality of steel pipes with different outside diameters, each transition segment is welded at the connected part of every two steel pipes, and the inclined annular metal rings are packaged outside the transition segments; when the stepped anti-settling pile leg is in installation, the pipe diameter of a corresponding stepped segment is determined according to the conditions of a surface foundation below a submarine mud surface, the stepped ring is driven into a place at the depth of 0.5-2.5 meters of the submarine mud surface when in submarine pile-leg driving construction to achieve the purpose of preventing settlement, and meanwhile, the driving depth of the pile leg can also be decreased by almost 1-3; and fillers are placed at the transition segments, i.e. the connected parts when the pile leg is driven on the spot, and the inclined annular metal rings are packaged outside the fillers and are favorable to bearing loads.
Description
Technical field
The utility model relates to the anti-sedimentation device of a kind of ocean platform spud leg, especially a kind of anti-sedimentation spud leg that is notch cuttype.
Background technology
Oil field, shallow sea, the beach ocean platform that usage quantity is maximum on stream in China Bohai Sea Gulf is a jacket platform, and this platform comprises jacket, spud leg and upper module.Each several part carry out on land prefabricated after, lifting migrates to the sea and installs again.Wherein drive piles behind the handling and securing after upending procedure, in the piling process, need one section one section ground of large-scale steel pipe spud leg is welded, then it is squeezed into the seabed.Yet owing to what squeeze into the seabed all is the identical spud leg of diameter, this spud leg relies on the stake and the frictional force of soil layer inspection to carry, be called friction pile, but because top weight is big, so the depth of drive of friction pile is very big, and the time one is long, and slow sedimentation can take place spud leg, brings potential safety hazard to the production on the ocean platform.
Summary of the invention
At the defective that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of notch cuttype anti-sedimentation spud leg, can reduce because of the long sedimentation that takes place service time after squeezing into the seabed, can also reduce driving depth simultaneously, the saving steel.
For achieving the above object, the utility model provides a kind of ocean platform notch cuttype anti-sedimentation spud leg, comprises spud leg, floor, cascade ring, changeover portion, endless metal circle, and floor is welded between spud leg and the cascade ring, and relieve stresses is concentrated; Cascade ring is formed by stacking by the different steel pipe welding of a plurality of external diameters, and the junction of per two steel pipes is welded with changeover portion, and changeover portion is surrounded by the endless metal circle of inclination outward.
Changeover portion is made of the steel loop and the riblet plate that tilt; Floor has 8-12, uniform being welded between spud leg and the cascade ring; The angle of endless metal circle and horizontal plane is 15 °-45 °; Cascade ring is a hollow body, and the caliber footpath becomes big successively from bottom to up; The caliber of cascade ring maximum is 2-4 a times of spud leg caliber; The endless metal circle is the iron sheet or the aluminium skin of 0.2-0.5 millimeter.
The anti-sedimentation spud leg of this notch cuttype earlier according to the situation of the following top layer of mud face, seabed ground, is determined the caliber of respective steps section, cascade ring is when the construction of seabed piling leg, squeeze into the depths of seabed mud face 0.5-2.5 rice, reaching the purpose of anti-settling, the spud leg depth of drive nearly also can reduce 1/3 simultaneously; When will driving piles leg at the scene, the changeover portion junction puts into filler, filler is surrounded by the endless metal circle of inclination outward, be beneficial to bearing load, it is in order to make long-time use after himself corrodes that the endless metal circle adopts slim iron sheet or aluminium skin, because of cross sectional shape changes, increase the resistance of sedimentation, to realize anti-efficiently sedimentation.
Compare with existing spud leg, have simple in structure, safe and reliable, flexible operation, advantage such as convenient and swift, cheap, economical and practical, and greatly improved the installation effectiveness of ocean platform, in the ocean platform installing engineering, had broad application prospects.
Description of drawings
Accompanying drawing 1 is the sectional view of the anti-sedimentation spud leg of ocean platform notch cuttype;
Accompanying drawing 2 is vertical views of the anti-sedimentation spud leg of ocean platform notch cuttype;
1-spud leg; 2-floor; 3-cascade ring; 4-changeover portion; 5-endless metal circle.
The specific embodiment
Shown in Fig. 1-2, the utility model comprises spud leg 1, floor 2, cascade ring 3, changeover portion 4, endless metal circle 5, and floor 2 is welded between spud leg 1 and the cascade ring 3, and relieve stresses is concentrated; Cascade ring 3 is formed by stacking by the different steel pipe welding of a plurality of external diameters, and the junction of per two steel pipes is welded with changeover portion 4, the changeover portion 4 outer endless metal circles 5 that are surrounded by inclination.
Using method: the anti-sedimentation spud leg of this notch cuttype, beach shallow foundation situation according to Bohai Sea Gulf, the caliber of determining the maximum order bench is 2.5 times for spud leg 1 caliber, and be provided with 3 the joint cascade rings 3, cascade ring 3 is when the construction of seabed piling leg, squeeze into the depths of 1 meter in seabed mud face, reaching the purpose of anti-settling, the spud leg depth of drive nearly also can reduce 1/3 simultaneously; When will driving piles leg at the scene, changeover portion 4 junctions put into the sandstone filler, filler is surrounded by the endless metal circle of inclination outward, be beneficial to bearing load, it is in order to make long-time use after himself corrodes that the endless metal circle adopts slim iron sheet or aluminium skin, because of cross sectional shape changes, increase the resistance of sedimentation, to realize anti-efficiently sedimentation.
