The most common form of pile driver uses a heavy weight situated between vertical guides placed above a pile. The weight is raised by some motive power (which may include hydraulics, steam, diesel, electrical motor, or manual labor). At its apex the weight is released, impacting the pile and driving it into the ground. [1] [3]

Pressure piling is a phenomenon related to combustion of gases in a tube or long vessel. When a flame front propagates along a tube, the unburned gases ahead of the front are compressed, and hence heated. The amount of compression varies depending on the geometry and can range from twice to eight times the initial pressure.
Screw piles were first described by the Irish civil engineer Alexander Mitchell in a paper in Civil Engineer and Architect's Journal in 1848; however, helical piles had been used for almost a decade by this point. [2] Screw foundations first appeared in the 1800s as pile foundations for lighthouses, [3] and were extensively used for piers in ...
Small charges of concrete can be added while the base is being formed [6] to enlarge the base and improve the pile’s settlement performance. [3] Franki piles can be installed raked (or sloped) with a tilt of up to 4:1. [5] Raked Franki piles are always reinforced and are particularly suitable for structures subject to dynamic forces. [1]
Tennessee Valley Authority civil engineers monitoring hydraulics of a scale model of Tellico Dam. Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings ...
In jet piling high pressure water is used to set piles. [9] High pressure water cuts through soil with a high-pressure jet flow and allows the pile to be fitted. [10] One advantage of Jet Piling: the water jet lubricates the pile and softens the ground. [11] The method is in use in Norway. [12]
Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber ...
