Pre Engineering Interview Question:

What are the different approaches in designing the floors of the service reservoirs?

Submitted by: Muhammad

In general there are two main approaches of designing the reservoir floors to prevent leakage of water due to seasonal and shrinkage movements:
☛ In this approach the movement joints of the reservoir floor panels are such that the free expansion and contraction of the panels takes place. Every panel is isolated from the other panels and two panels have a sliding layer between them to help in sliding.
☛ The second method does not provide any room for free movement. With seasonal and shrinkage movements, some cracks are designed to voluntarily occur on the floors of the service reservoirs. These tiny cracks are spread throughout the floor and are simply too minute to cause any leakage or corrosion of the floors. But the difference also in this method is that the amount of reinforcement used is much more than the first approach.
