  • Earth anchor
    Patent number: 4142336
    Abstract: An improved grouted earth anchor having a modified end configuration that reduces undesirable tensile stress in the grout ball. The reduction in tensile stress is accomplished by locating the enlarged end section of the end configuration of the anchor rod away from the bottom of the grout ball, and by shaping the enlarged end section in a predetermined manner in order to make the compressive stress trajectories between the surface of the enlarged end section and the surface of the grout ball as straight as possible.
