Abstract
The invention relates to an auger boring rig for drilling an earth layer, in particular to a simulated spiral drill provided with an unsmooth surface. The simulated unsmooth spiral drill is to have the unsmooth surface by regularly arranging convex hulls on blades of a common spiral drill; the total area of the convex hulls on the blades occupies 15 to 30 percent of the area of the blades; and the convex hulls are uniformly or randomly distributed in the shape of a concentric circle, a diamond, an equiangular triangle or a radial shape. As shown by compared drilling tests between the simulated unsmooth spiral drill and the prior common spiral drill, compared with the smooth blade spiral drill, the simulated unsmooth blade spiral drill is difficult to cling to the earth, has obvious antisticking and anti-drag properties, improves the earth removal rate by 70 percent, reduces the power consumption of the drill, reduces the fuel consumption of the drill by 53.3 percent, greatly improves the drilling efficiency, and reduces the drilling cost. The technical proposal of the simulated spiral drill is suitable for a Luoyang spade.
Description
Technical field
The present invention relates to a kind of auger boring facility that bore the digging layer, especially have the bionical auger boring facility of non-smooth surface.
Background technology
The geologic body that is run in the geotechnical engineering drilling construction has rock stratum, gravel layer, sandy soil layer and soil layer, and the drilling tool that adopts has inferior wheel brill, Churn drill, auger usually.Churn drill is only applicable to competent bed and gravel layer, inferior wheel bores and is not only applicable to competent bed and gravel layer, also be applicable to sandy soil layer and soil layer, but creep into soil layer especially argillic horizon be that efficient is lower, produce in auger or Luoyang is to creep into the particularly effective tool of argillic horizon of soil layer.Existing spiral drill casting is to lean on the rotation of the blade of spiral drill to be delivered to the face of land, the soil bits that bored are inevitable in the soil that rises to produce friction with blade, especially when creeping into clay stratum, because the big soil of viscosity being attached on the helical blade tightly, defeated soil resistance is increased, cause the casting difficulty, carry and also need spend behind the brill plenty of time to remove soil on the spiral drill, greatly reduce drilling efficiency; Moreover, because the clay soil block is attached on the helical blade, increase torsion, increase the rig power consumption.Domestic relevant spiral drill casting Research on Working shows, soil block or native ball are thrown under centrifugal action on the hole wall and produce frictional force with hole wall on the blade, after this frictional force has only overcome the frictional force that soil rises with blade, soil block just can prolong hole wall and rise automatically, so the size of the frictional force of soil block and blade has also determined the power consumption of rig.The big resistance of spiral drill in clay stratum creeps into and the soil of lifting from after the boring that removes are handled the efficient of creeping into are reduced greatly.Therefore, drag reduction and the bonding helical blade of desorption soil bits are that spiral drill improves the key of creeping into operating efficiency, and all there is this problem in existing spiral drill.
Occurring in nature, some live in the animal in the soil, through the evolution to For hundreds of millions of years in millions of years, generated the body surface that conforms, as dung beetle, mole cricket and earthworm etc. all is to bore the self-taught expert, can activity in the soil of viscosity extremely freely, and that self body surface is put soil is sticking, has outstanding drag reduction desorption function.The expert who is engaged in bionics Study is through a large amount of tests and research, the result shows, the non-smooth form that the body surfaces of these soil faunas exists, that the non-smooth morphology of this biology surface has is antiseized, drag reduction, characteristic such as wear-resisting, and has formed a kind of perverse bionic, non-smooth new theory.Biological non-smooth antiseized drag reduction theory is confirmed the bionical new technology of produced a series of saving materials, raising the efficiency, reducing cost by numerous test.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned the deficiencies in the prior art, and a kind of bionic non-smooth spiral drill is provided.
The objective of the invention is to be achieved through the following technical solutions:
Bionic non-smooth spiral drill is clocklike to be provided with convex closure 2 to constitute non-smooth surface on common spiral drill blade 1.
Technical scheme of the present invention is applicable to luoyang spade.
Purpose of the present invention can also be achieved through the following technical solutions:
The gross area of the convex closure 2 on the blade 1 accounts for the 15%-30% of blade 1 area, the center distance 10-20mm of convex closure 2 and convex closure 2, convex closure 2 high 2-5mm, convex closure 2 bottom surface diameter 3-5mm; Convex closure 2 is concentric-ring pattern, rhombus, equilateral triangle, radial shape, even or random distribution on blade 1; Convex closure 2 on the blade 1 adopt the manganese steel welding rods directly on blade built-up welding go out convex closure.
Beneficial effect; Bionic non-smooth spiral drill provided by the invention and existing common spiral drill have carried out the contrast drilling test, bionic, non-smooth blade screw drilling tool more is difficult for clay than smooth blades spiral drill, antiseized, drag reduction is extremely remarkable, take off native rate and improved 70%, reduced the rig power consumption, the rig fuel consumption reduces by 53.3%, has greatly improved drilling efficiency, has reduced and has bored the pick cost.
