Geogrid sand fence

摘要

A geogrid sand fence for depositing matter moved by wind currents and related methods, are provided. A geogrid sand fence for the control of sand or other particulate matter movement can include support members carrying a fencing material. The fencing material can include a High Density Polyethylene geogrid mesh material having apertures distributed to provide approximately a 50% porosity to maximize sand deposit volume. The geogrid mesh material has sufficient structural weight to be employed with a height of approximately two meters, which can be adjusted to maintain maximum effectiveness.

1. A method for depositing sand moved by wind currents, the method comprising the steps of:
controlling between approximately 80% and 85% or more of moving sand particulate matter moved by the wind currents in a sand environment through employment of a single row sand fence positioned at an offset distance from a structure to be protected, the single row sand fence having a structural configuration designed to maximize particulate matter precipitation and accumulation on a leeward side of the sand fence prior to the wind currents reaching the structure to be protected, the step of controlling between approximately 80% and 85% or more of moving sand particulate matter moved by the wind currents in the sand environment, comprising:
determining the offset distance from the structure to be protected,securing a plurality of support members to a surface at the offset distance from the structure to be protected, the plurality of support members extending downward into the surface a first preselected distance and extending upwardly from the surface a second preselected distance, andattaching a polymer fencing material to the plurality of support members to thereby form a sand fence, the polymer fencing material having a height of approximately 2.0 meters and having a plurality of apertures having diameters in a range of between approximately 6 mm to 10 mm and distributed to provide a fencing material porosity of approximately 50% to thereby maximize the reduction in a speed of the wind currents as the wind currents move through the fencing material and maximize an amount of sand carried by the wind to be deposited on the leeward side of the sand fence prior to the wind currents reaching the structure to be protected.
