PILE DRIVING FINAL EXAMS ANSWERS AND
QUESTIONS SET A+
✔✔Plug - ✔✔The soil inside a pipe pile driven open-end.
✔✔Precast Pile - ✔✔A concrete pile either reinforced or prestressed which is
manufactured in a construction yard or at the site, and having been properly cured, is
handled and driven like a steel or timber pile.
✔✔Precast Segmental Pile - ✔✔A precast pile manufactured in lengths which enable
the pile to be extended on site relatively quickly which a mechanical splice.
✔✔Pressure-Treated Pile - ✔✔Round or sawn timber used as a pile, which has been
pressure impregnated with a chemical preservative, e.g., creosote, pentachlorophenol,
or ammoniacal copper arsenate or chromate copper arsenate
✔✔Prestressing - ✔✔Methods of increasing the load-bearing capacity of concrete by
applying increased tension on steel tendons or bars within an element.
✔✔Pretensioning - ✔✔A method of prestressing a concrete member in which cables or
rods are jacked against and then anchored to abutments in a form before the concrete
is poured. When the concrete member has cured to specified strength, the tendons are
detached from their anchorages and relieved of their stress. Restrained from shortening
by a bond with the concrete, the tendons compress the concrete member.
✔✔Ram Point - ✔✔The part of the ram that comes closest to the impact surface of the
pile. Sometimes a separate unit of the ram.
✔✔Ram - ✔✔The moving or driving part of an air, steam, diesel or drop pile hammer
which delivers an impact blow to an anvil and to the pile.
, ✔✔Rectangular Cofferdam - ✔✔A temporary wood or steel sheet piling, braced, single-
walled, rectangular shaped enclosure installed to permit construction of a foundation
below ground or water level.
✔✔Reinforced Concrete - ✔✔Concrete with embedded reinforcing bars or fibrous
material to provide additional tensile strength.
✔✔Reinforced Pile - ✔✔A regular piling shape that is strengthened with plates welded
to the flanges. By this means, section moduli and resisting moments can be increased
considerably
✔✔Reinforcing Steel - ✔✔Steel bars with deformed little projecting edges to insure that
they will not pull out of the concrete and that the bond between the steel and concrete
will be perfect. It comes in round bars in smaller sizes and square bars in larger sizes. It
is bent or straight according to where the added strength is needed.
✔✔Screw Pile - ✔✔A pile with spiral blade fixed on a shaft or a shaped precast pile,
which is screwed into ground by a rotating force.
✔✔Semi-Automatic Pile Hammer - ✔✔A power pile hammer for which the valve is
manually thrown at one end of the stroke and automatically thrown at the other end.
✔✔Sheet Pile - ✔✔A pile that may form one of a continuous line or row of timber,
precast concrete, or steel piles driven interlocked to provide a tight wall to exclude or
resist lateral pressure of water, adjacent earth or other materials.
✔✔Single-Acting Hammer - ✔✔A pile hammer in which a heavy ram is lifted by
steam/air/diesel explosion/etc. and falls by its own weight.
✔✔Soldier Pile - ✔✔An H or wide-flange (WF) member driven at intervals of a few feet
into which horizontal lagging is placed to support the walls of an excavation.
✔✔Spud - ✔✔Driving a hard metal point into the ground, then removing and driving the
pile.
✔✔Spudding - ✔✔The act of opening a hole through dense material by dropping a
driving spud.
✔✔Steel H-Pile - ✔✔A rolled-steel section with web and flanges nearly the same
thickness. The width and depth are approximately equal.
✔✔Steel Pipe Pile - ✔✔Pipe in any wall thickness or diameter; it may be driven closed
end or open end.
