Description
Technical field
The utility model relates to a kind of steel pipe pile, particularly relate to a kind of in establish the steel pipe pile of multiple arc stiffening rib.
Background technology
Along with the development of national economy and the progress of science and technology, the exploitation for the energy is advanced to ocean by land, comprises offshore oil, offshore wind farm etc.Current ocean engineering base form has the forms such as gravity type foundation, single-pile foundation, spider basis, basic, the High-Rise Pile Cap Foundation of jacket, buoyant foundation and suction cartridge type basis, when design condition is suitable, single-pile foundation has obvious advantage in design, manufacture and construction.For marine wind electric field, under most depth of water and fan loads condition, steel pipe pile single-pile foundation is top-priority base form.
Along with the increase of the seawater depth of water and the raising of blower fan capacity of power unit, the diameter of single-pile foundation steel pipe is also increasing.Along with the increase in stake footpath, according to the regulation of specification, the wall thickness of steel pipe pile also increases thereupon, and offshore steel pile tube single-pile foundation mostly is opening pile, in-site measurement field data show, super-large diameter open end steel pipe pile soil plug effect is more weak, the side friction that the inner soil body of stake can provide is far short of what is expected, bearing capacity of pile tip is very low, need enough stakes long come bonding pile vertical carrying capacity, above factor all causes steel using amount obviously to increase, material cost increases, difficulty of processing increases, the transport that dead load causes, construction waits the also corresponding increase of other costs, have impact on the economy of object of construction production.Therefore need a kind of safe and reliable, be beneficial to the ribbing steel pipe pile manufacturing and designing, alleviate deadweight, reduce material and costs such as transport construction etc.
Utility model content
In order to the weak point in solving the problem, the utility model provide a kind of in establish the steel pipe pile of multiple arc stiffening rib.
For solving above technical problem, the technical solution adopted in the utility model is: the steel pipe pile establishing multiple arc stiffening rib in a kind of, and it is made up of steel pipe and stiffening rib; Stiffening rib is arranged on the inside wall of steel pipe uniformly; The both sides of stiffening rib vertically adopt fillet weld seam on the inside wall of steel pipe; A perfusion area is formed between stiffening rib and the inside wall of steel pipe.
The set-up mode of stiffening rib is that elongated setting or local are arranged.The quantity of stiffening rib is multiple, shape is circular arc.
The utility model designs more that science, structure are rationally, stress performance is superior, safe and reliable, be beneficial to manufacture and design, transport few from heavy and light, iron and steel materials and construction cost low, more convenient and practical.

Detailed description of the invention
As Figure 1-Figure 4, the utility model is made up of steel pipe 1 and stiffening rib 2; Stiffening rib 2 is arranged on the inside wall of steel pipe 1 uniformly, and the set-up mode of stiffening rib 2 is that elongated setting or local are arranged.The quantity of stiffening rib 2 is 4 or multiple, and the shape of stiffening rib 2 is circular arc or other curve form.
The both sides of stiffening rib 2 vertically adopt fillet weld 3 or other modes to be welded on the inside wall 1 of steel pipe 1; A perfusion area is formed between the inside wall of stiffening rib 2 and steel pipe 1; Can pour in perfusion area or not concrete perfusion 4.
Construction method of the present utility model is:
A, in steel work processing factory by steel pipe 1 roll forming and segmentation welding is formed overall;
B, vertically adopt fillet weld 3 or other modes to be welded on the inside wall of steel pipe 1 stiffening rib 2, other accessory structures also can be complete in factory-assembled in advance;
C, by assembling after whole stake be transported to stake position by special transport boats and ships, adopt relevant device carry out piling construction and pile body beaten to design elevation, then carry out the process of jackstone protection against erosion;
D, according to design needs, concrete perfusion 4 in the perfusion area formed between stiffening rib 2 and the inside wall of steel pipe 1, reaches until it and to carry out other constructions follow-up after design strength and install.
Multiple arc stiffening rib is set up in large diameter steel pipe pile, thickness of steel pipe and Weight of steel can be reduced, the community that arc rib is formed forms soil plug completely when being interposed between piling, bearing capacity of pile tip can be improved, need to fill at soil according to design and separate interior concrete perfusion between rear arc rib and outer wall of steel pipe, thus can pile body stiffness be improved, reduce pile body by corroded area, improve structure durability, and circular arc rib self stability is fine, and improve stake inside sliding block and bearing capacity of pile tip, can concrete perfusion in what arcuate rib and steel pipe pile lining were formed separate, pile body stiffness can be significantly improved, under identical designing requirement, stake will be effectively reduced long, reduce material, transport, the costs such as construction, there is good economy.In addition, when arcuate rib and steel pipe pile lining formed separate interior concrete perfusion time, also can reduce pile body by corroded area, improve structure durability.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing; the change that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
