What we have learnt
- Different types of pile hammers include drop hammers, single acting steam hammers, and double acting steam hammers.
- The selection of a pile hammer should consider the weight of the pile and the type of soil.
- The productivity rates of different types of hammers can significantly affect project timelines.
Key Concepts
- -- Drop Hammer
- A drop hammer is a heavy metal weight that is dropped on the pile to drive it into the ground, relying on gravity for impact.
- -- Single Acting Steam Hammer
- This type of hammer uses steam energy to lift the hammer during the upward stroke, while the downward stroke relies on gravity.
- -- Double Acting Steam Hammer
- A hammer that uses steam energy for both the upward and downward strokes, enhancing impact efficiency.
- -- Leader
- A supporting frame structure that ensures the alignment of the pile and hammer during installation.
