Single helix earth anchors Guyed mast anchor. An earth anchor is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as a ground anchor, percussion driven earth anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
A deep-penetrating anchor (DPA) is conceptually similar to a torpedo anchor: it features a dart-shaped, thick-walled, steel cylinder with flukes attached to the upper section of the anchor. A full-scale DPA is approximately 15 metres (49 ft) in length, 1.2 metres (4 ft) in diameter, and weighs on the order of 50–100 tonnes (49–98 long tons ...

U.S. Army soldiers use a military standard metal detector. A metal detector is an instrument that detects the nearby presence of metal. Metal detectors are useful for finding metal objects on the surface, underground, and under water. A metal detector consists of a control box, an adjustable shaft [dubious – discuss], and a variable-shaped ...
In ground-anchored guys, the structure which attaches the guy-wire to the ground is called an anchor. [4] The anchor must be adequate to resist the maximum tensile load of the guy wires; both the dead load of the tension of the wire and the maximum possible live load due to wind.
A number of types of detecting technology can be employed by such instruments, including use of magnetic fields, radio frequencies, signal generation, metal detectors, ground-penetrating radar and RFID. [2] Cable locator tool in use with spray marking can for marking location Survey marking
UK Coal was the United Kingdom's largest coal mining company, producing approximately 8.7 million tonnes of coal annually from deep mines and surface mines, and possessed estimated reserves in excess of 200 million tonnes of coal. [11] The firm was the successor of British Coal, which was privatised in 1997.
A reptile tooth and a fish tooth from the Blue Anchor Formation, Somerset The formation is named from the village of Blue Anchor on the coast of west Somerset. It consists largely of green to grey mudstones and siltstones (which gave rise to the earlier name of this sequence, the Tea-green Marls) and varies from around 5 m to 67 m in thickness.
