The coaxial steel tube foundation aims at the problems of the existing wind driven generator foundation, and provides the coaxial steel tube foundation with the advantages that the construction is convenient and fast, and economy and reliability are realized. The foundation consists of the outer tube and the inner tube, the outer tube has bending resistance and shearing resistance and is connected with an upper end tower tube, the inner tube is driven into the supporting layer to resist the sedimentation, and the inner tube and the outer tube are connected through the separation plate and are combined to form a complete resistance system.
Description
Technical field
The invention belongs to the technical field of single-pipe tower architecture basics engineering, be specifically related to a kind of coaxial steel cylinder basis with inside and outside cylinder.
Background technology
Current many Pile-supported stand foundations of the more use of wind-power electricity generation single-pipe tower architecture basics in water level area under weak soil, height.Engineering quantity is large, cost is high, long in time limit.Also useful steel pipe single-pile foundation gets to bearing stratum; If bearing stratum is very dark, piling bar is very long, and cost is high, then adds piling bar top and do cushion cap, uneconomical.
Summary of the invention
Object of the present invention is exactly the problem that will exist for above-mentioned existing wind driven generator base, and convenient, the economic reliably coaxial steel cylinder of a kind of construction basis is provided.This foundation main will consist of urceolus and inner core, and urceolus bending resistance shearing resistance is also connected with upper head tower cylinder, and inner core is got to bearing stratum anti-settling, between inside and outside cylinder, by dividing plate, connects, and inside and outside cylinder is in conjunction with forming a complete drag system.
The technical solution adopted in the present invention is:
A kind of coaxial steel cylinder basis, comprise blower fan tower barrel, basis urceolus, outer scab, slotted hole frictional high-strength bolts, interior scab, soil supporting layer, long screw, basis inner core, dividing plate, ground Soft Soil Layer, it is held and levies is that described blower fan tower barrel is connected with basic urceolus with interior scab by outer scab, basis urceolus is embedded in ground Soft Soil Layer, slotted hole frictional high-strength bolts is simultaneously through outer scab, blower fan tower barrel and interior scab, or select slotted hole frictional high-strength bolts simultaneously through outer scab, basis urceolus and interior scab, basis inner core is connected with basic urceolus by dividing plate, the bottom of basis inner core is supported on soil supporting layer, basis urceolus and dividing plate, the connection of basis inner core and dividing plate is with bolts.
Further illustrate a kind of coaxial steel cylinder of the present invention basis:
Described urceolus, inner core coaxial combination profile and composite force form.
Described basic urceolus and the junction of tower body adopt long screw to be used for finely tuning the verticality of coxopodite blower fan tower barrel.
Described dividing plate is the steel plate that has honeycomb shape.
Described basic urceolus and tower body adopt the splicing of slotted hole high-strength bolt double shear.
Described scab adopts embossed steel plates.
The edge bending of described interior scab increases its flexural strength.
The operating principle and the construction sequence that further illustrate a kind of coaxial steel cylinder of the present invention basis are:
1, with high-frequency vibratory hammer, inner core is pressed into base center on-site, and its top is exposed be highly equal to urceolus height.
2, urceolus is installed, and is connected the dividing plate between urceolus and inner core.
3, with high-frequency vibratory hammer, be pressed into coaxial cylinders basis to design elevation.
4, measure cylinder top absolute altitude levelness, with high-frequency vibratory hammer, adjust.
5, lifting coxopodite tower cylinder, and make inside and outside scab be located in inner side and the outside of the seam of upper and lower cylinder.
6, penetrate from inside to outside high-strength bolt, tentatively screw in.
7, adjust vertical height.
The present invention contrasts existing with Pile-supported stand foundation, and usefulness is:
1, adopt urceolus bending resistance, the form of inner core anti-settling, meeting tall and slender structure bending resistance is main loading characteristic.A large amount of material usages that reduce.
2, rapid and convenient is installed in the on-the-spot splicing in pure steel structure basis (segmentation transportation).
3, basic urceolus and tower body adopt the splicing of high-strength bolt double shear, the good and simplified structure of no-welding-seam fatigue resistance and save cushion cap.
4, employing long screw in the junction of basic urceolus and tower body is used for finely tuning the verticality of pylon, the inclination in modified basis urceolus allowed band.
5, connect the dividing plate employing of the inside and outside cylinder in basis with the steel plate of honeycomb hole, save steel using amount.
6, scab adopts embossed steel plates, improves friction factor.Further improve the structure efficiency connecting.
7, steel cylinder basis sinks conveniently in soft foundation, and does not need to process underground water, saves construction investment.
