Abstract:
A mechanical ground anchor comprising:an elongated core member;an anchor body comprising a plurality of part-cylindrical members surrounding said core member and movable between a closed position close to said core member and an open position spaced radially farther from said core member than said closed position, wherein in said closed position each said part-cylindrical member abuts each adjacent said part-cylindrical member to form a closed cylindrical body, and in said open position, said part-cylindrical members are spaced apart from one another;each said part-cylindrical member provided with at least a pair of slide mechanisms that mount said part-cylindrical members for reciprocal radial movement relative to said core member, said pair of slide mechanisms on each said part-cylindrical member being longitudinally spaced apart from one another; andat least one drive mechanism interconnecting said core member and each said part-cylindrical member to drive said part-cylindrical members between said closed position and said open position;whereby said spaced apart slide mechanisms provide increased strength to said ground anchor during a rotary driving of said anchor into the ground.
