The total length of described pile body 1 is L, in top-down direction,
L is extremely
L sections are the first cone 6, and the longitudinal profile of the first cone 6 is two symmetrical the first outwardly camber lines 12, and the radius of curvature of the first camber line 12 isL；
L is extremely
L sections are the first cylinder 7；L is extremely
L sections are the second cone 8, and the longitudinal profile of the second cone 8 is two symmetrical the second outwardly camber lines 13, and the radius of curvature of the second camber line 13 isL；
L is extremely
L sections are the second cylinder 9；Below L is the 3rd cone 10, and the longitudinal profile of the 3rd cone 10 is two symmetrical the second outwardly camber lines 14, and the radius of curvature of the second camber line 14 is
L。
The spacing of fin of described helical blade 15 is 35-45mm, and the width of helical blade 15 is 8-12mm.
The utility model compared with the existing technology, has the following advantages that：
The stepped foundation auger pile of this kind of structure type, its is simple in construction, design is ingenious, rhombus is revised as in the sophisticated cross section of existing pile by it by traditional circle, the tip of this structure can provide more powerful group native ability, the present apparatus is set to be more suitable in the harder environment of the soil properties such as high latitude area, its cone is not common coniform simultaneously, but tool is made up of the curved surface of special shape, and these curved surfaces are stepped to be set, on the one hand this structure makes pile more laborsaving during installation, improve operating efficiency, on the other hand bigger fixed force can also be provided, the building for the pile for having used the present apparatus is allowed more to consolidate, safety.And its manufacture craft is simple, cheap for manufacturing cost, it can be said that this foundation auger pile possesses a variety of advantages, is particularly suitable for popularization and application in the art, possesses extensive market prospects.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings embodiment of the present utility model.As shown in Figure 1：A kind of stepped foundation auger pile, including pile body 1, this pile body 1 is made up of the cannulated sleeve 2 and cone 3 being connected with each other, the upper end surface of cannulated sleeve 2 is provided with ring flange 4, multiple connecting screw holes 5 are evenly over the circumference distributed with ring flange 4, these connecting screw holes 5 can be screw or arcuation hole；
Cone 3 is from top to bottom made up of the first cone 6, the first cylinder 7, the second cone 8, the second cylinder 9 and the 3rd cone 10 successively, tip 11 is provided with the lower end of the 3rd cone 10, the cross section at tip 11 is rhombus；
The total length of described pile body 1 is L, in top-down direction,
L is extremely
L sections are the first cone 6, and the longitudinal profile of the first cone 6 is two symmetrical the first outwardly camber lines 12, and the radius of curvature of the first camber line 12 is
L；
L is extremely
L sections are the first cylinder 7；
L is extremelyL sections are the second cone 8, and the longitudinal profile of the second cone 8 is two symmetrical the second outwardly camber lines 13, and the radius of curvature of the second camber line 13 is
L；
L is extremely
L sections are the second cylinder 9；
Below L is the 3rd cone 10, and the longitudinal profile of the 3rd cone 10 is two symmetrical the second outwardly camber lines 14, and the radius of curvature of the second camber line 14 is
