Leveling and Bore Alignment

Question 1

To level means to?

Answer 1

Put into the same plan as the horizon

Question 2

Describe the difference between flat and level?

Answer 2

Level is level to the horizon where flat can be flat but on an angle

Question 3

What is plumb?

Answer 3

To align perpendicular to horizontal

Question 4

Describe square?

Answer 4

Somthing that is aligned 90 degrees to reference line.

Question 5

The advantages of optical lines of site are :

Does not sag

Cannot be kinked

____________

There is no tripping hazard

Remains straight for long distances

Can measure within thousands of an inch

Answer 5

Does not vibrate

Question 6

What are some problems using optical lines?

Answer 6

• Problems shooting through heat waves, causes distortion

-Shooting through glass, refracts (bends) the line of sigh and gives false reading.

• shooting through an opening that is to small, using a sitting block can improve accuracy
• Shooting near edge of a hole, can bend the line of sight due to reflection and refraction

Question 7

What is the advantage of using a pentaprism (5-sided) over standard prism?

Answer 7

Penta prism does not reverse the image

Question 8

Answer 8

Optical

.001

.0001

Question 9

What are the two types of scales?

Rough alignment

And

Answer 9

Precision alignment (.001” accuracy)

Question 10

The alignment bar is for _______?

Answer 10

Simple, versatile, and economical way of achieving the desired precision reading over 100 ft

Question 11

Tilting levels are used strictly for _________?

Answer 11

Levelling procedures

Question 12

What is a way to check if your reference line is level?

Answer 12

By checking from both ends

If it is level it will be the same on both ends

Question 13

A plumb aligner bracket is used to_______?

Answer 13

Establish a vertical plumb line quickly and easily

Question 14

1: is it level
2: is it flat
3: is it plumb
4: is it straight
5: is it square

Question 15

Answer 15

Optical

Question 16

Checking the vertical accuracy of a jig transit or theodolite can be accomplished with what________?

Answer 16

Plumb bob in a bucket of oil

Question 17

What are theodolites used for?

Answer 17

To measure angles in horizontal and vertical planes

All purpose instruments with the ability to shoot and measure the angle of slope or angle of deviance from a horizontal reference line.

Can be more complicated to set up

Question 18

Wire alignment when done properly can provide accuracy as close as ________\?

Answer 18

.0001”

Question 19

What is one problem when using horizontal wire alignment is __________ to over come this you must refer to ________

Answer 19

Wire sag

Sag charts

Question 20

What are the three catagories of lasers:

High accuracy, long distance
