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]
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.
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.

In this context, "engine" referred to a military machine, i. e., a mechanical contraption used in war (for example, a catapult). As the design of civilian structures such as bridges and buildings developed as a technical discipline, the term civil engineering [5] entered the lexicon as a way to distinguish between those specializing in the ...

Some troops leave the battlefield injured. Others return from war with mental wounds. Yet many of the 2 million Iraq and Afghanistan veterans suffer from a condition the Defense Department refuses to acknowledge: Moral injury.
