PILE DRIVING STUDY EXAMS SET ANSWERS AND
QUESTIONS SET A+
✔✔A supporting pile for a structure that can be of wood, concrete or steel in any
number of shapes and whose bearing is reached by point or end bearing, friction, or
friction and compaction, or a combination.
Select one:
a. Steel H-Pile
b. Steel Pipe Pile
c. Bearing Pile
d. Pedestal Pile - ✔✔bearing pile

✔✔A two (or more) part resin that, when mixed, produces a high-strength bonding
material.
Select one:
a. Reinforcing Steel
b. Grout
c. Epoxy Grout
d. Reinforced Pile - ✔✔epoxy grout

✔✔A fabricated guide used to align the piling before driving. Circular templates may
have one or more rings against which piles are set to form the circle of the cell. This can
be almost any shape; square, rectangular, etc. Single walls are generally set against a
beam as a guide.
Select one:
a. Leads
b. Compression Leads
c. Template
d. Fixed Leads - ✔✔template

✔✔The entire area where, in the event of a pile accident resulting in the collapse of the
crane and leads system, personnel on the ground could be struck by falling equipment

,or objects dynamically affected by falling equipment such as stored piles, towers, other
standing equipment.
Select one:
a. Driving Theater
b. Penetration Test
c. Failure of a Pile Foundation
d. Drive Sleeve - ✔✔driving theater

✔✔A proprietary Augered Pile. High strength grout is forced down the center of a flight
auger to form a shaft as the auger is withdrawn.
Select one:
a. Precast Pile
b. Tension Pile
c. Augercast
d. Non-Displacement Pile - ✔✔augercast

✔✔The use of a water or air jet to facilitate the placing or driving of a pile by means of
hydraulic displacement of parts of the soil. In some cases, a high-pressure air jet may
be used, either alone or with water.
Select one:
a. Nonvibrating Weight
b. Jacking
c. Impact Velocity
d. Jetting - ✔✔jetting

✔✔The use of a water jet to assist in driving piles into sand speeds up the driving
operation.
Select one:
True
False - ✔✔true

✔✔Steel pipe piles are most efficient as friction piles as they have substantial surface
area that interacts with the surrounding soil to provide significant frictional load
resistance.
Select one:
True
False - ✔✔true

✔✔Load-bearing piles are used primarily to transmit structural loads.
Select one:
True
False - ✔✔true

✔✔Hydraulic leads are less costly than standard fixed leads.
Select one:

Select one:
a. Double-Acting Hammers
b. Differential-Acting Hammers
c. Single-Acting Hammers - ✔✔single acting hammer

✔✔Which type of pile can penetrate into soils that other types of pile cannot?

Select one:
a. Precast-Prestressed Concrete Piles
b. Steel Piles
c. Timber Piles
d. Cast-in-Place Concrete Piles - ✔✔steel piles

weight piles into soils having normal frictional resistance?

Select one:
a. Differential-Acting Hammers
b. Single-Acting Hammers
c. Double-Acting Hammers - ✔✔double acting hammers
