The analyze resulted in the event of the number of charts, which could then be accustomed to estimate pile stresses and resistance for concrete piles. The study also dealt with quite a few technical troubles that remain of curiosity to at the present time, such as instrumentation and knowledge selection on stresses and forces in piles, the outcome of the hammer cushion within the technology and effect on the pile worry wave, the relationship of ram body weight to pile weight and cross area, and fall tower tests on cushion material to find out cushion stiffness.

Where by quick pile driving results in entire horizontal cracks inside of a concrete pile, calculated rigidity stresses can be off. If the tension stresses are too superior, insert cushioning or reduce the length with the hammer stroke. If way too pile driver micro goomba reduced, it may be connected with lousy hammer performance.
Pile drivers can reach varying depths according to soil problems and the type of hammer utilized. Depths commonly vary from various meters to over 100 meters in specific applications.
