3. Factors Affecting Hammer Selection

Try these first

1. 1.

   What type of hammer is recommended for concrete piles?

   Hint

   Think about stresses on concrete when dealing with pile driving.

2. 2.

   Which soil type requires a heavier hammer?

   Hint

   Which soils stick together more tightly?

3. 3.

   What hammer type is optimal for dense cohesive soils?

   • Double Acting Hammer
   • Single Acting Hammer
   • Vibratory Hammer

   Hint

   Consider what type provides the most power.

4. 4.

   True or False: Heavy hammers should be avoided when driving concrete piles in tough soil.

   • True
   • False

   Hint

   Think about stress on the pile.

5. 5.

   Assess the impact of selecting a vibratory hammer in a region known for its dense, clay-like cohesive soil. What may result?

   Hint

   Consider how vibrations might respond to dense materials.

6. 6.

   In a scenario where a double acting hammer is used for a lightweight steel pile in loose soil, analyze the consequences of this choice.

   Hint

   Think about how weight and resistance interact with hammer energy.
