7.2. Basic Principle of Pile Driving

Try these first

1. 1.

   What is one benefit of using bentonite slurry in piling?

   Hint

   Think about how the slurry interacts with the soil.

2. 2.

   What does pre-stressing do to concrete piles?

   Hint

   Consider what internal stresses can do.

3. 3.

   What is the main purpose of conducting soil tests before pile installation?

   • To determine the moisture level
   • To understand soil behavior
   • To check for contaminants

   Hint

   Think about what characteristics of soil affect pile performance.

4. 4.

   Pre-stressing is applied to increase the load-bearing capacity of piles?

   • True
   • False

   Hint

   Recall what pre-stressing aims to achieve.

5. 5.

   You have a construction project at a site with very unpredictable soil layers. Discuss how you would determine the best pile type to use and justify your choices.

   Hint

   Focus on how soil behavior dictates your pile type.

6. 6.

   Given a task to pre-stress concrete piles, outline the steps you would take from tendons setup to concrete pouring and eventual tension release.

   Hint

   Recall the sequence of operations related to pre-stressing.
