In construction, the term pile refers to a prefabricated element that is installed by hammering it into the ground. Piles are usually made from various materials including timber, steel, and concrete. The hammering is done using a pile driving hammer, which is also referred to as a pile driver. Driving hammers are used to drive piles into the soil so that they can offer foundation support for structures such as buildings. This is what one should know about marine pile drivers.
Pile drivers on the other hand may also be used to refer to the crew that works with a pile driving hammer. Ordinary lateral and compressive loads can be supported by the use of piling. On the other hand, drilled shafts support more loads than piles. It is for this reason that piles are categorized as footings when it comes to supporting heavy loads. This activity is mostly carried out in East Texas in the United States.
Piling activity is most suited for softer soils that are easier to penetrate without causing damage to piles. That means that hard soils and rocks are not suitable for piling activities. Load capacity gained by piling comes from skin friction. Also, end bearing of the piling can be significantly increased if its tip is placed inside a rock layer or packed soil. That means that such piles support more weight better.
The driving system is composed of several components that serve different functions. These components are leads, power hammer, helmet connects, and the cushioning. The function of the leads is to hold the hammer and piling in place to ensure that the two components are aligned with each other. It would be catastrophic if the hammer missed the tip of the piling when it is coming down. In fact, the force of the hammer would damage the piling badly.
The work of the power hammer is to lift and drop heavy rams which in turn drive the piling deeper into the soil. The source of power of the power hammer is air pressure or diesel. The helmet connects the top of piles to the hammer. Thus, helmet ensures the descent of the hammer makes contact with the pile.
The whole operation involves huge forces which may cause damage to the hammer and the pile. A cushioning is therefore placed in between the two to prevent damage. The function of the cushion is to prevent excess stress and absorb some energy. This ensures the system can last for a long time.
When working, it is very important to pay attention to the condition of the cushion. Sometimes, the cushion may get damaged and in turn cause damage to both piles and hammers. To be safe, not more than three piles should be driven using the same cushion block. If necessary, the cushion should be changed as frequently as possible. Regular inspection should be done before, during, and after a driving operation.
Matching the size of the piles and the size of the hammers is very important. Penetration cannot be effective in case the hammer is too tiny for the piling. On the other hand, when very large hammers are used inappropriately they can lead to high comprehensive and tensile forces.
