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. Earth anchors are used in both temporary or permanent applications, including supporting retaining walls, guyed masts, and circus ...
Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
Bored pile retaining wall in Lisbon, Portugal. Bored pile retaining walls are built by assembling a sequence of bored piles, followed by excavating away the excess soil. Depending on the project, the bored pile retaining wall may include a series of earth anchors, reinforcing beams, soil improvement operations and shotcrete reinforcement layer.
Helical anchors consist of an extendable steel shaft with helical bearing plates. Piles or piers refer to strong base elements that withstand or transfer vertical/horizontal loads. Anchors are piles utilised only in tension applications like restraining wall tiebacks or vertical ground anchors made to resist overturning forces.
The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...
Earth moving equipment (c. 1922) Flattened and leveled construction site. Road roller in the background. Excavation may be classified by type of material: [1]: 13.1 Topsoil excavation; Earth excavation; Rock excavation; Muck excavation – this usually contains excess water and unsuitable soil
When selecting an anchor, consider the element formwork and the ease of placement and securing of the anchor prior and during the pouring of the concrete. For example, some of the anchors shown in figures 4-6, can be placed into thin wall elements as the anchor chair maintains the position relative to the element thickness.
