Specific implementation mode
Embodiment 1
A kind of compound pile pile of resistance to plucking, as shown in Figs 1-4, including inner core 4 and setting are matched in 4 outside of inner core with inner core 4
Outer core 1;Inner core 4 is hollow cavity structure, and dowel 2 is equipped in inner core 4, and regular reinforcement or deformed bar can be used in dowel 2,
The specification and quantity of dowel 2 determine that 6 length of anchoring section is determined according to calculating according to design anti-pulling capacity;It is evenly equipped in inner core 4
Steel or plastic products can be used in the locating support 5 being connected with dowel 2, locating support 5, and locating support 5 is setting up and down, adjacent
Locating support 5 between spacing be no more than 2m;4 bottom end of inner core is equipped with end plate 12, and 2 bottom end of dowel stretches out end plate 12 and passes through spiral shell
Mother 11 fixes with end plate 12;2 top of dowel is more than or equal to without departing from 4 top of inner core and 2 top of dowel and the spacing on 4 top of inner core
800mm;4 top of inner core is equipped with plug at end part 3;Dowel 2 is divided into free segment 7 and anchoring section 6, the anchoring section 6 of dowel 2 from top to bottom
