Patent ID: 7090440

Claim:
A method for slope stabilization comprising: identifying a target slope with a potential or actual translational landslide by the presence of colluvial soil, a slope angle of between 1 horizontal to 1 vertical and 3 horizontal to 1 vertical, hummocks, soil fissures, soil cracks, toeing, a pre-existing slide, or soil creep where the target slope has an x-axis and a y-axis; determining the target slope area by measuring or estimating the area of the target slope; calculating a sufficient number of plate piles needed to create a series of alternating rows covering the entire target slope area in a diamond-shaped lattice pattern where a first row, and all subsequent odd-numbered rows, contains a plurality of plate piles inserted four feet center-to-center along the x-axis of the target slope, a second row, and all subsequent even-numbered rows, is placed ten feet away from the first row along the y-axis of the target slope, and contains a plurality of plate piles inserted four feet center-to-center along the x-axis of the target slope, and where the even-numbered row plate piles are offset from the odd-numbered row plate piles, and all subsequent even and odd rows continue the calculated pattern to cover the target slope area; transporting the number of plate piles to the target slope; inserting a plurality of plate piles into the target area in a series of alternating rows in the calculated diamond-shaped pattern covering the entire slope; and driving at least one of the plate piles below the ground surface into the bedrock.
