EXAM COMPLETE 110 QUESTIONS AND CORRECT DETAILED
ANSWERS
What do electrical grid mats that are bonded to a fluid assisted boring
system provide? - CORRECT ANSWER✔✔Operator protection in case of
contact with electrical lines the boring equipment and machine operators
are at the same electrical potential
Which type of vibratory plow is an attachment to a tractor or trenches and
requires a ground person to manually guide the conduit into the feed chute
as the plow cuts through the ground? - CORRECT ANSWER✔✔The
Modular Vibratory Plow
In which areas is the use of a Vibratory plow much more economical than
trenching? - CORRECT ANSWER✔✔In underdeveloped areas where a
large tractor can be maneuvered
How can coaxial cable be plowed using a plow machine without a cable
reel carrier? - CORRECT ANSWER✔✔Lay the coaxial cable along the
bury route and have a helper guide the coaxial cable into the feed chute of
the forwarding plow
When preparing to plow conduit how long should the starter trench be? -
CORRECT ANSWER✔✔A length that allows the plow blade to be lowered
to the burial depth without violating the minimum bend radius of the
attached conduit
When using a surface dry boring machine what is the preferred forward
speed of the machine? - CORRECT ANSWER✔✔A speed that allows a
boring bit to work freely without being forced
What is the purpose of a portable conduit fishing system? - CORRECT
ANSWER✔✔It is used to blow a pull line through the conduit
, How much contraction will 1200ft of conduit have if the temp changes from
94F to 54F when the rate of contraction is 1 1/2 in per 100ft per 20F
change? - CORRECT ANSWER✔✔36 inches
When directly burying coaxial cable, - CORRECT ANSWER✔✔Avoid
reverse bending of the coaxial cable when unreeling the coaxial cable
What is the proper method for removing the coaxial cable from its reel for a
direct burial operation? - CORRECT ANSWER✔✔With the reel on an
appropriate stand pull the cable from the bottom of the reel
What may be required to remove a large rock from the ground during
trenching? - CORRECT ANSWER✔✔Using a Backhoe
When digging the trench, - CORRECT ANSWER✔✔First confirm that all

What should be done before using a Chain Trencher? - CORRECT
ANSWER✔✔It should be inspected for any loose bolts, broken chain
teeth, or any types of fluid leaks before beginning its operation
What does the Boom do to the Chain on the Chain Trencher? - CORRECT
ANSWER✔✔It is spring loaded to create tension on the chain
When backfilling the trench, - CORRECT ANSWER✔✔Gravel, a soil
stabilizer, or a slurry mixture should be used when proper compaction is
difficult to obtain with the present trench material
What are some of the factors in determining the total length of pre-
assembled cable in a conduit for a trench site? - CORRECT ANSWER✔✔
Thermal expansion contraction allowance
What is required for checking the physical network integrity when
maintaining the coaxial cable network? - CORRECT ANSWER✔✔Being
observant and performing some minor tasks while engaged in regularly
scheduled activities
