As one preferably technical scheme, described pile top 14 is the scopes of the hypomere 48 being arranged in pile crown 10, and comprise scraper plate 38, leading most advanced and sophisticated 50 and sharpener 52, described scraper plate 38 is cylindrical.
As one preferably technical scheme, the skin 42 of described scraper plate 38 is no more than the diameter 34 of a connector 12 in the range size that radial direction extends along axis 40.The basal surface of described scraper plate 38 forms helical form continuously, i.e. spiral bottom surface 44, the horizontal profile on described spiral bottom surface 44 overlaps with the vertical plane of axis 40, the continuous print helical outer surface 46 that described scraper plate 38 is formed intersects with spiral bottom surface 44, described helical outer surface 46 forms acute angle A with axis 40, described acute angle A is 4 ° ~ 6 °, usually selects 5 °, and described acute angle A opposed helical external surface 46 is little with the angle on spiral bottom surface 44.
As one preferably technical scheme, described leading most advanced and sophisticated 50 is reverse pyramidal structures 51, and described pyramidal structure 51 forms symmetrical sharpener 52 to soil downward-extension, described pyramidal structure 51 be stand upside down most advanced and sophisticated dome shape.
As one preferably technical scheme, form larger angle between the intrados 54 of described sharpener 52 and axis 40, close to about 20 °.The least significant end part 56 of sharpener 52 is to extend to form the fish tail shape of rotation below symmetrical structure forward guide nose end 50.
As one preferably technical scheme, the diameter of described stake 28 is 30cm ~ 90cm.
The beneficial effects of the utility model are: the utility model structure reduces piling required time, fixing welded construction between stake and stake connector and pile crown, axle center has better end bearing loading capability on the same line, and structure is more firm, and tension pull out force and overturning moment effect strengthen.
