A soldier pile wall using reclaimed railway sleepers as lagging. Soldier piles, also known as king piles or Berlin walls, are constructed of steel H sections spaced about 2 to 3 m apart and are driven or drilled prior to excavation. As the excavation proceeds, horizontal timber sheeting (lagging) is inserted behind the H pile flanges.
Extant wartime records were thought to be fairly poor, and nobody could be sure how many pillboxes and related hardened field defences had survived—or indeed, how many had been constructed in the first place. In the late 1970s, journalist Henry Wills began research on the topic, eventually publishing Pillboxes: A Study of UK Defences in 1985 ...
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]
In this way, a soldier can improve the position over time, while being able to stop at any time and use the position in a fight. Typically, a DFP is a pit or trench dug deep enough to stand in, with only the head exposed, and a small step at the bottom, called a fire step, that allows the soldier to crouch on to avoid fire and tank treads.
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.

Timber-pile bridge with steel stringers, New Jersey Timber pilings serve as the foundations of many historic structures such as canneries, wharves, and shore buildings.The old pilings present challenging problems during restoration as they age and are destroyed by organisms and decay.
First, the deposit is "undercut", where a slot is cut as deep as possible along the bottom of a section of ore. This undercut allows for a manageable pile of rock in later stages. The second step is the drilling and blasting of the section. This creates a pile of ore that is loaded and hauled out of the mine—the final step of the mining ...
One of at least 29 experimental piles that were constructed in 1942 under the West Stands of Stagg Field. Each tested elements incorporated into the final design. The pile was built in September 1941 from 4-by-4-by-12-inch (10 by 10 by 30 cm) graphite blocks and tinplate iron cans of uranium oxide. The cans were 8-by-8-by-8-inch (20 by 20 by 20 ...
