Piles. Because piles are driven into ground, they are slender members. Therefore, the load-bearing capacity of an individual pile is small. A (concrete) pile cap integrates multiple piles into one foundation element.In placing concrete into the drilled hole for a pier, special equipment is used. What is that equipment and what function does it serve?
What will be an ideal response?
The equipment used is called a tremmie, which is simply a long steel pipe with a funnel at the top. Its purpose is to take the concrete into the depths of the bored hole. Without a tremmie, the concrete would have a free fall into the hole, separating particles of the concrete mix.
