Reliable, lightweight and convenient multi-helix soil anchors for deployable structures and shelters

"A refined helical screw configuration is proposed as an efficient, versatile andeconomical anchor for deployable structures and shelters; the system designallows for convenient and rapid driving into soil through rotation. The refinedhelical screw configuration complements high frictional resistance with addedbearing capacity. The proposed Phase I research will: (1) quantify the designparameters of anchor system; (2) fabricate prototypes and validate theirtechnical features and ease of use; and (3) identify and test chemical stabilizersthat enhance performance of the system in weak, saturated soils. The Phase I Optionwill: (1) develop and verify optimum system designs; and (2) assess competitiveposition of the technology in different applciations. The efficient anchor design proposed here maximizes load-carrying capacity,minimizes weight, and allows for rapid and convenient installation. The system issimple and amenable to low-cost manufacturing. The new design is versatileand suits diverse site conditions. Major applications of the anchor systeminclude deployable structures and shelters, slope stabilization, retaining wallstabilization, and foundations for small structures in difficult soils.Technova Corporation has formed an alliance with a major anchor/fastenermanufacturer (Hilti Inc.) and a leading academic institution in the field(The University of Michigan, Ann Arbor) towards development and broadcommercial implementation
