Ground treatment assistance method comprising providing a machine comprising a ground treatment tool is provided, providing geographic coordinates of at least one treatment area, determining positioning data of the ground treatment tool using an optical acquisition device, displaying at least a first object representative of the ground treatment tool or of said at least one treatment area on a display device, and positioning said first object on the display device using the previously determined positioning data of the ground treatment tool and the geographic coordinates of said treatment area.

Devices, systems, and methods for installing earth anchor foundations and/or conducting load tension tests on earth anchors used to secure structures, such as solar platforms, trellises, tents, decking, bleachers, telephone poles, powerlines, construction scaffolding, and the like. In one example, the device includes a base plate, a plurality of elongate telescoping members extending from the base plate and containing a crank mechanism. A drive shaft on the upper member is coupled to the crank mechanism to raise and lower the upper member relative to the base plate. A support arm or shelf is provided on the upper member for raising a frame during installation of the structure, and a testing hook is provided on the upper member for conducting a load tension test on one or more earth anchors used to secure the structure using a load measurement device coupled to the hook and the earth anchor(s).

A post-tensioned tube foundation for supporting a structure subject to high upset forces is described herein. The post-tensioned tube foundation includes an outer CMP, an inner CMP, and a tubular concrete base positioned between the inner CMP and the outer CMP. The outer CMP includes an inner surface that defines a cavity extending between a first open end and an opposite second open end. The outer CMP is positioned within an excavated hole defined along a ground surface. The inner CMP is positioned within the cavity of the outer CMP such that an annular space is defined between the inner CMP and the outer CMP. The tubular concrete base is positioned within the annular space defined between the inner CMP and the outer CMP. A plurality of bracing beams extend radially outwardly from the tubular concrete base.

A foundation component having an elongated shaft with a below-ground end and an opposing above-ground end. The foundation component is installed by sleeving it over a mandrel and applying downward force to the mandrel to insert the component and mandrel into underlying soil. Proximate to the underground end, the shaft has one or more crumple zones formed along its length. When the mandrel is rotated to a locked position and upward force is applied while bracing the above-ground end of the component, one or more of the crumple zones expand transversely into the soil, depending on the soil's density, thereby increasing the component's bearing capacity and resistance to pull out.
