The correct answer is D. All of the above.
Raymond piles are a type of foundation pile that is driven into the ground by a Raymond hammer. They are typically made of steel and have a conical shape. The length of Raymond piles varies from 6 m to 12 m, the diameter of the top of the pile varies from 40 cm to 60 cm, and the diameter of the pile at the bottom varies from 20 cm to 28 cm.
Raymond piles are used in a variety of applications, including the construction of buildings, bridges, and other structures. They are a popular choice for foundation piles because they are strong, durable, and easy to install.
Here is a brief explanation of each option:
- Option A: The lengths of Raymond piles vary from 6 m to 12 m. This is because the length of the pile needs to be sufficient to reach a stable bearing stratum. The bearing stratum is the layer of soil that is strong enough to support the weight of the structure.
- Option B: The diameter of the top of piles varies from 40 cm to 60 cm. This is because the diameter of the pile needs to be large enough to provide a large surface area for the pile to transfer the load to the ground.
- Option C: The diameter of pile at bottom varies from 20 cm to 28 cm. This is because the diameter of the pile needs to be small enough to allow the pile to be driven into the ground.
I hope this helps!
