Example Embodiment
[0017] There are three types of optimized friction cast-in-place piles made by the pile expander, which are characterized in that there are pairs of rectangular pile cones protruding on the cylindrical pile body, which are perpendicular to the axis, radially symmetrical or staggered; Figure 1a , Figure 1b The first type of cast-in-place pile type A shown is a pair of rectangular pile cones 2 protruding on the cylindrical pile body 1, each pair is radially horizontally symmetrical, perpendicular to the center of the circle, and staggered in the axial direction of the pile body; Figure 2a , Figure 2b The second type of the multiple sets of rectangular pile cones 2 of the cast-in-place pile type B shown is that the two pile cones of each pair of rectangular pile cones are staggered in the axial direction of the pile body 1 with a height of a rectangular pile, respectively symmetrical to the same Diameter, two pairs perpendicular to the center of the circle; Figure 3a Figure 3b ...
