What Do You Mean By Screw Piles

Screw piles are also referred as screw anchors or some might call them as screw piles or helical piles. The screw piles are a mechanism name used for constructing the deep foundations. It is usually considered as the easiest type of deep foundation that can be easily installed. It produces minimum noise and the vibration produced is also minimized.  The wounding of screw piles is similar to the wounding a steel in to the wood, just like that the screw piles is wounded in to the ground. The screw piles are very efficient. These are combined with the mechanism of load dispersion which makes it even more effective in the areas where there are high rates of earthquakes.

The manufacturing of screw piles involves an anchor shaft or sometimes these are manufactured by hollow sections. These are made in various sizes and there is no standard size for this. The piles are constructed using helices. Number of helices are attached to the screw piles. Then these piles are wounded into the ground by using heavy machinery that are able to move the earth. The shafts of the screw piles and the flights of helical are manufactured according to the ground. The condition of the ground helps manufacturer to determine that which type of helices must be used on the screw piles so that these are appropriate for particular type of ground condition.

It is predetermined that to which depth the screw pile must reached. Depending on this depth the size of screw pile is determined. When the screw pile is wounded in to the ground and it reaches the defined target depth then it is fixed there permanently. In order to make sure that these screw piles do not move from their place these are fixed by using concrete.

The screw piles are installed by using hydraulic motors. These motors are very powerful and provide strong torque that is sufficient enough to screw these piles into the ground. A handling machine is also used along with the hydraulic motor. Each one of them is used in combination with another and must fulfil each other requirement in order to produce the required torque. Both of these should match the minimum requirement for the torque that is used for installation. It should also be kept in consideration that what are the height and width limitations of the particular site also the shaft must be checked for its capacity of the torsional.
