Description
Technical field
The utility model relates to a kind of foundation pile, relates in particular to a kind of earthbound solar energy power station special-purpose blade drilling rod piling bar that is exclusively used in.
Background technology
Solar power station generally is based upon the open field of open-air desert, known ground desert type solar-electricity stands in when beating foundation pile, construction sequence is loaded down with trivial details, the job site is dirty and messy, be to excavate foundation ditch at the scene, ram base, bury prefabricated concrete stake backfill original soil then underground, or on-the-spotly excavate assembling reinforcement cage and supporting template, job mix concrete casting and maintenance behind the foundation ditch.The construction period of known technology is very long, need long-term curing concrete, causes open-air material transportation tissue difficulty because of material is wide in variety, and logistics cost greatly, wild environment constructional difficulties, working area be big, the heavy damage vegetation.Can't construct by season and weather effect, be subject to special geologic condition and can't construct, the whole fund input of project strengthens.
The utility model content
The purpose of this utility model is to provide earthbound solar energy power station, a kind of earthbound solar energy power station special-purpose blade drilling rod piling bar, to overcome the defective that exists in the known technology.
For achieving the above object, earthbound solar energy provided by the invention power station special-purpose blade drilling rod piling bar is a steel pipe, one end of this steel pipe is the drill bit formula metal construction of taper, cross, tooth row's shape or in-line, fixedly connected flange of the other end of steel pipe or special-purpose connecting parts have provided the screw type blade on the body of steel pipe.
The utility model also comprises special-purpose blade drilling rod piling bar connector, this special use blade drilling rod piling bar connector is a steel pipe, each fixes a connecting parts (connecting parts can be structures such as flange, U-shaped structure or box section) two ends of this steel pipe, has provided the screw type blade on the body of steel pipe.
The steel pipe of the present utility model outside all is coated with anticorrosive coat.
The diameter range of steel pipe of the present utility model is 50mm-1500mm.
The beneficial effects of the utility model are, because of blade drilling rod piling bar has adopted the structure form of variable cross-section to satisfy distribution Regularity of Additional Stress and stress is shared the requirement of stiffness variation when, adjusted the effect between soil and the stake, stake side soil body stress is shared when, and the stress diffusance improves, stake end load reduces, and makes pile body stressed harmonious with earth stress.Special-purpose blade drilling rod piling bar has changed interactional pattern between the stake and the soil body, and the piling process king-pile side soil body is squeezed, compacted effect, and stake has constituted the mechanical type interlock with the pedosphere face, makes it have more firm characteristics.A piling back stake side soil body forms nut, and a pile body screw thread and the tight interlock of stake side soil nut further strengthen firm performance, unsinkability energy and the anti-pulling performance of blade drilling rod piling bar.
The utility model makes more simply that because of material structure cost of transportation significantly reduces; Do not need to repair on a large scale that soil, quick construction are convenient, construction sequence is few, the few characteristics of construction manpower will make construction period significantly shorten, it is with the obvious advantage to reduce construction costs, and can make the power station project run generating in advance, the shortening investment repayment phase; Foundation pile intensity height, load is big, sedimentation is little, shock resistance is good; Geological adaptability is good: adapt to multiple soil layer and comprise desert, grassland, beach, Gobi desert, severe cold areas permafrost region, lithostratigraphy, beach, shallow sea special geology environment such as (below 5 meters), construction and pile quality are not subjected to influence on groundwater; Climate adaptability is good: can reach in the winter time under the bad climate condition and construct; Environment protecting is good: do not fetch earth, pollution-free, do not destroy ecology and vegetation, when the power station operation finished back or other reasons end item, utilization was connected with pile body with pile driving equipment, by reverse rotation and lift and easily realize the conveniently purpose of recovery; Can connect standard and nonstandard support easily.
