The micropile slide stabilization system (MS3) consists of an array of micropiles, working in tension and compression, that connect as a system using a structurally reinforced grade beam to stop slide movements.
Process
The micropile slide stabilization system (MS³) retains soil by connecting an array of drilled and grouted micropiles, sometimes combined with ground anchors, to a reinforced concrete beam constructed near the ground surface.
A small bench is cut into the slope to allow access to the micropile drill rig. A reinforced concrete beam is first constructed on the ground surface, through which micropiles are then drilled at angles. The micropiles are then grouted and connected to the beam. The finished micropiles act in tension and compression to effectively create an integral, stabilized ground reinforcement system to resist sliding forces in the slope. The grade beam can be buried, hiding the slope stabilization system from view.
