Description
Technical field
This utility model belongs to wind power generation field, is a kind of enhancement mode marine wind electric field single-pile foundation.
Background technology
Single-pile foundation is a kind of conventional offshore wind plant wind turbine foundation form, a piece steel pipe hammering is rammed sea bed or boring is arranged on sea bed the basis formed, general basis a diameter of 3～6m, wall thickness is about the 1% of diameter, the degree of depth inserting sea bed is relevant with the intensity of the soil body, transmit fan loads mainly by soil pressure against piles, be primarily adapted for use in shallow water and the moderate water area of 20～25 m, soil condition preferable marine wind electric field project.This basis has been widely used for European offshore wind park at present.
And the major defect of existing single-pile foundation is: the weight of single-pile foundation is big, construction equipment is required of a relatively high, the most important thing is that single-pile foundation antidumping and anti-Its ultimate bearing capacity are of close concern to each other with the degree of compaction of soil layer, requiring that soil layer has certain density, particularly the shallow soil close to earth's surface can not be the loosest or too soft weak.It is true that offshore wind farm place mostly is loose ground or weak soil, it is impossible to provide enough pile-soil interactions, the horizontal displacement on Long-term Cyclic Loading effect Single Pile basis will persistently increase, and be easily caused single-pile foundation lateral tilt.In Practical Project, this type of example is of common occurrence.
The most effectively prevent single-pile foundation from tilting, ensureing its safety in utilization, be current problem demanding prompt solution.
Utility model content
Being solved the technical problem that of the present invention is i.e. providing a kind of enhancement mode marine wind electric field single-pile foundation with tubular flank, possesses extremely strong antidumping and anti-Its ultimate bearing capacity.
The technological means that this utility model is used is as described below.
A kind of enhancement mode marine wind electric field single-pile foundation, comprises single-pile foundation, and on this single-pile foundation, ring sets the tubular flank that Open Side Down, and tubular flank can be one-body molded with single-pile foundation, or the welding of tubular flank with on single-pile foundation.
Setting a circle ribbed stiffener between described tubular flank and single-pile foundation, ribbed stiffener is a plurality of, and ring single-pile foundation border is uniformly arranged.
Described tubular flank top sets at least two circle osculums.
Described perfusion by osculum forms concrete layer.
Described concrete is cyclopean concrete or plain concrete.
Nano anti-corrosive material is sprayed on described single-pile foundation and tubular flank.
The described single-pile foundation being provided with tubular flank passes through hydraulic vibration driver linked manner pile sinking in sea bed.
Have the beneficial effect that produced by this utility model.
1, on single-pile foundation, tubular flank is increased.Change the mechanical behavior of conventional single-pile foundation, on the one hand moment of flexure can be converted into pulling force and pressure by tubular flank, improving its resistance to capsizing, on the other hand tubular flank vertical side can increase substantially horizontal bearing capacity, it is to avoid occurs that single-pile foundation lateral tilt was lost efficacy.
2, between single pile and tubular flank, ribbed stiffener is set, it is ensured that effective connection therebetween.
3, osculum is set on tubular flank, on the one hand can arrange sea water in pile driving process, be beneficial to pile sinking, on the other hand can also be by this hole perfusion cyclopean concrete (or low grade plain concrete), with the impact overcoming sea bed landform height to rise and fall.
4, jackstone process is made on the sea bed surface around tubular flank, improves the protection against erosion ability of single-pile foundation.
5, anti-corrosion mode uses novel nano anti-corrosion material, to guarantee structural anticorrosion performance and durability.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model enhancement mode marine wind electric field single-pile foundation.
Detailed description of the invention
A kind of enhancement mode marine wind electric field single-pile foundation of this utility model protection, comprises single-pile foundation 1, and on this single-pile foundation 1, ring sets the tubular flank 2 that Open Side Down, and it can be arranged by welding or integrated mode.For ensureing that single-pile foundation 1 is effectively connected with tubular flank 2, therebetween setting ribbed stiffener 3, this ribbed stiffener 3 is a plurality of, and ring single-pile foundation border is uniformly arranged, with every 60 ° arrange one, to set 6 altogether be optimal to a circle, other are up to the set-up mode of firm effect certainly.Tubular flank 2 top can set at least two circle osculums 5, and it can discharge sea water in pile driving process, it is possible to is made cylindrical interior form concrete layer 4 by osculum perfusion further, with the impact overcoming sea bed landform height to rise and fall.The concrete of perfusion can use cyclopean concrete or plain concrete (low grade plain concrete).
Owing to the corrosivity of marine environment is relatively strong, single-pile foundation and tubular flank spray nano anti-corrosive material, to ensure structural anticorrosion performance and durability.
Owing to single-pile foundation is heavier, particularly adding the above-mentioned single-pile foundation possessing tubular flank and ribbed stiffener, pile sinking mode may select hydraulic vibration driver linkage pile sinking in sea bed.
Time actually used, single-pile foundation generally uses steel-pipe pile, stake footpath to be 3～6m, and wall thickness is about the 1% of diameter.Being burn-on by marine wind electric field single-pile foundation tubular flank, tubular flank diameter is about 4 times of single-pile foundation diameter, and the tubular flank degree of depth is about 0.5 times of single-pile foundation diameter.Treating that single-pile foundation sinks in the soil body, tubular flank sinks in sea bed therewith, and keeps the laminating as far as possible of tubular flank top and sea bed top.The osculum diameter about 1m at tubular flank top, arrange along single-pile foundation border, it is optimal to arrange one every 30 °, sea water is arranged in pile driving process, it is beneficial to pile sinking, it addition, by this osculum perfusion cyclopean concrete (or low grade plain concrete), with the impact overcoming sea bed landform height to rise and fall.In order to improve the protection against erosion ability of single-pile foundation, the sea bed surface jackstone around tubular flank processes.
Conventional single-pile foundation relies primarily on lateral earth pressure resist torque and horizontal loading, enhancement mode single-pile foundation of the present utility model is in addition to relying on lateral earth pressure, on the one hand moment of flexure can be converted into pulling force and pressure by its tubular flank, improving its resistance to capsizing, on the other hand tubular flank vertical side can increase substantially horizontal bearing capacity.Owing to marine environment is relatively strong, use novel nano anti-corrosion material, to guarantee structural anticorrosion performance and durability.This utility model can increase substantially single-pile foundation antidumping and Lateral resisting ability, it is to avoid occurs that single-pile foundation lateral tilt was lost efficacy.
