Abstract
The utility model discloses a shallow sea single pile platform casing pipe reinforced pile, comprising two steel pipes with different diameters connected by steels, the utility model is characterized in that the steel pipe with large diameter is sheathed on the steel pipe with small diameter, their diameter relation is as three-D, the steel pipe with large diameter is as long as three-D, and the annular space is welded with symmetrical ribbed panels; when the pile enters the shallow soil layer in the seabed, the external casing pipe makes full use of the coactions between the piles and the earth to enlarge the pile lateral area and the contact earth volume, so the utility model improves the horizontal and vertical bearing ability of the pile foundation as well as shortens the pile length. The utility model enlarges the pile lateral area, the utility model improves vertical bearing ability of the pile foundation, and the utility model shortens the pile length.
Description
One, technical field
The utility model relates to the solely stake platform sleeve pipe reinforcement stake of a kind of shallow sea.
Two, background technology
Ocean platform is the basic facility of offshore oil natural gas resource exploitation.Along with the exploitation that deepens continuously of offshore oil and gas resource, the fixed Light Platform that research is suitable for the shallow sea oil-gas field development becomes the main subject topic.Since the eighties, Shengli Oil Field is just studied application to Light Platform, has been at present the key facility in exploitation oil field, shallow sea.Recently, the researcher is optimized design to piling strtucture on the basis of pile-soil interaction, has proposed the solely stake platform sleeve pipe reinforcement stake of a kind of new shallow sea.
Three, summary of the invention
The purpose of this utility model is for making full use of the native interphase interaction of stake, save the platform cost, in the application life of raising platform drag and prolongation platform, having designed solely stake platform sleeve pipe reinforcement stake of shallow sea.
The technical solution of the utility model realizes in the following manner:
The utility model is connected to form by steel by two different steel pipes of diameter, it is characterized in that the big steel pipe socket of diameter is on minor-diameter steel-tube, its diameter Relationship is 3 times of little diameter of steel tube for the big steel pipe diameter, the length of big steel pipe is 3 times of little diameter of steel tube, its annular space is welded with the ribbed panel of symmetry, its stake is gone in the submarine shallow soil layer, made full use of interaction between stake soil by outer side sleeve, it is long-pending to have enlarged the stake lateral area and the passive area soil body, improved the level and the vertical bearing capacity of pile foundation, it is long to have shortened stake.
Compared with the prior art the utility model has the following advantages:
1, increases the bending rigidity and the shear stress of stake, reduced the dynamic response of stake.
2, enlarged the stake lateral area, improved vertical bearing capacity, it is long to have shortened stake.
3, enlarge the passive area soil body and amassed, improved the drag and the horizontal bearing capacity of pile foundation soil.
Four, description of drawings
Fig. 1-structural representation of the present utility model;
A-A is to schematic diagram among Fig. 2-Fig. 1.
1-steel pipe 2-steel pipe 3-floor
Five, embodiment
For further disclosing the technical solution of the utility model, be described in detail by embodiment below in conjunction with Figure of description:
With floor 3 on the steel pipe 1 periphery balanced welding, put steel pipe 2 and with floor welding, the diameter of steel pipe 2 is 3 times of steel pipe 1 diameter.The length of steel pipe 2 is 3 times of steel pipe 1 diameter.Its method with piling is squeezed into the seabed, large diameter steel pipe and floor are slipped in the sea-bottom shallow soil.At last offshore platform is welded in stake end week side of surfacing the only stake platform in shallow sea, this new structure has saved the solid stake of traditional jacket structure and slip casting system.Have safe and reliable, small investment, construction is fast, use value is high characteristics.
Claims (1)
1, the only stake in shallow sea platform sleeve pipe reinforcement stake is connected to form by steel by two different steel pipes of diameter, it is characterized in that the big steel pipe socket of diameter is on minor-diameter steel-tube, its diameter Relationship is 3 times of little diameter of steel tube for the big steel pipe diameter, the length of big steel pipe is 3 times of little diameter of steel tube, its annular space is welded with the ribbed panel of symmetry, its stake is gone in the submarine shallow soil layer, made full use of interaction between stake soil by outer side sleeve, it is long-pending to have enlarged the stake lateral area and the passive area soil body, improved the level and the vertical bearing capacity of pile foundation, it is long to have shortened stake.
