4.2. Performance of Diesel Hammers in Cohesive Soil

Try these first

1. 1.

   What type of hammer is recommended for concrete piles?

   Hint

   Think about the requirement to reduce the stress on the pile head.

2. 2.

   How is blow energy calculated?

   Hint

   Remember the formula: W x H.

3. 3.

   What is the main purpose of selecting the appropriate hammer type?

   • To reduce cost
   • To ensure effective pile driving
   • To improve aesthetic appeal

   Hint

   Think about the functional requirements of pile driving.

4. 4.

   True or False: Diesel hammers are not suitable for cohesive soils.

   • True
   • False

   Hint

   Recall the performance characteristics of diesel hammers.

5. 5.

   A construction site requires driving piles into stiff clay that requires high blow energy. What type of hammer would be most suitable, and why?

   Hint

   Consider the blow energy needs for tough soil.

6. 6.

   During a project, an engineer finds that noise restrictions limit the use of standard hammers. What alternative hammer should be considered and why?

   Hint

   Think about the types of hammers that minimize noise yet drive effectively.
