2. Supporting Equipment for Pile Driving

Try these first

1. 1.

   What is a drop hammer?

   Hint

   Think about gravity's role in this process.

2. 2.

   Why is it important to use a pile cushion?

   Hint

   What happens to an object when it is hit without cushioning?

3. 3.

   What is the primary function of a drop hammer?

   • To create vibrations
   • To drive piles using gravitational energy
   • To lift weights

   Hint

   Think about how the hammer moves.

4. 4.

   True or False: A single acting hammer uses steam for both upward and downward strokes.

   • True
   • False

   Hint

   Recall how steam energy is applied in each type of hammer.

5. 5.

   During a construction project, a contractor needs to drive a concrete pile weighing 25,000 kg using a single acting hammer. If the best available hammer weighs only 7,500 kg, what should the contractor do?

   Hint

   Review the minimum weight criteria discussed.

6. 6.

   If a double acting hammer has a lifting efficiency of 80% and operates 50 blows per minute, how many effective blows can be registered in one hour?

   Hint

   Consider units of time when calculating total output.
