Sample interview questions: Can you explain your approach to ensuring proper drainage and slope in newly installed drain systems?
Sample answer:
Approach to Ensuring Proper Drainage and Slope in New Drain Systems
-
Thorough Site Investigation: Conduct a thorough site inspection to assess the terrain, soil conditions, and elevation changes. This information informs the design of the drainage system to ensure proper slope and flow direction.
-
Accurate Slope Calculations: Utilize appropriate formulas and slope gauges to determine the optimal gradient for each drain pipe section. The slope is critical to maintain proper flow velocity and prevent blockages.
-
Precise Pipe Laying: Install pipes in accordance with the calculated slope and elevations. Use a level and stringline to ensure accuracy. Properly support the pipes with hangers or straps to maintain gradient.
-
Avoid Sharp Bends: Minimize the use of sharp bends or curves in the drain system. These can create resistance to flow, leading to blockages and decreased drainage efficiency.
