In jet piling high pressure water is used to set piles. [8] High pressure water cuts through soil with a high-pressure jet flow and allows the pile to be fitted. [9] One advantage of Jet Piling: the water jet lubricates the pile and softens the ground. [10] The method is in use in Norway. [11]
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.
A related weapon is the angkusa or elephant-goad measuring 2–3 ft (0.61–0.91 m) long with a tip of steel or bronze. Southeast Asian royals and generals would ride elephants either into war or during processions. Every elephant was guarded by one to four handlers, each of whom carried an angkusa.
Franki piles can be used as high-capacity deep foundation elements without the necessity of excavation or dewatering. [4] They are useful in conditions where a sufficient bearing soil can only be reached deeper in the ground, [5] [6] and are best suited to granular soil where bearing is primarily achieved from the densification of the soil around the base.

The width of the throat determines the flume size; 22 standardized sizes have been developed, ranging from 1 in to 50 ft (0.005 ft 3 /s to 3,280 ft 3 /s). A venturi flume is similar to the Parshall flume, without the contoured base, but the cross section is usually rectangular, the inlet shorter, and there is a general taper on the outlet ...
Screw foundations first appeared in the 1800s as pile foundations for lighthouses, [3] and were extensively used for piers in harbours. Between the 1850s through 1890s, more than 100 screw-pile lighthouses were erected on the east coast of the United States using screw piles. Made originally from cast or wrought iron, they had limited bearing ...
The D575A-3SD measures 16 feet 0 inches (4.88 m) tall, 38 feet 5 inches (11.71 m) long has a ground clearance of 2 feet 5 inches (0.74 m). [ 2 ] The D575A-3SD features a Super Dozer blade designed to dump, dig or carry that measures 11 feet 11 inches (3.63 m) high and 24 feet 3 inches (7.39 m) wide.
