Hammer timber pile is something people use to work with. Maybe, you should google it sometime. If you did, I'm very sorry that you couldn't find anything but I will help you :D
If someone driving in fence-posts with a hammer is observed at a distance of several hundred yards, it will be apparent that the sound of the hammer striking the post is not coincident with the action; it will be heard as the hammer is being raised for the next stroke. The same effect can be observed when watching a pile-driver at a similar distance.
an anomaly in the reflectogram can be caused by necking if the curve deflects first in the direction of the hammer blow, and then in the opposite direction before returning to normal. in the European usage, the hammer blow is plotted downwards. thus a necking in the pile causes the reflectogram to deflect first downwards and then upwards. if the anomaly is in the upper half of the pile, it can repeat itself one or more times, depending on the pile profile and soil properties. all consequent reflections will have the same characteristics as the first one - downward and then upward.
hit it with a hammer, stroke it with a magnet or flow an electric current through or closely around it!
You can use hammer, press or vibrationdrivers. The most common are hammer and vibrationdrivers, which pound on or vibrate the pile to sink it into the ground. Where noise or vibration would be a no-no, pressdrivers can be employed.Hammer drivers can be operated mechanically, hydraulically or pneumatically. In all types of hammer driver, the ram is raised in a slide and allowed to drop on the head of the pile. Repeat until the pile is at the required depth. Make sure you are wearing your ear protectors if you're nearby. Hammer driving can also have a detrimental effect on nearby buildings, as the seismic waves generated are powerful. Typically the ground around the driver will jump a few inches with each blow.(There is a method in which the ram is constructed to form a single cylinder diesel engine but I'm unfamiliar with this technique. Most of the pile drivers I've seen were hydraulically raised hammer or mechanical vibration types.)Vibration drivers operate on a different principle. Usually there is a hydraulic arm and a motor driving an eccentric cam or a shaft which is weighted to put it out of balance; the vibration causes the earth to assume liquid-like properties and the pile slowly glides in under the pressure of the pile driver arm. This is nowhere near as noisy as hammer driving. Unfortunately the powerful seismic vibration can have a bad effect on nearby buildings and can be quite unpleasant for nearby humans.Press drivers use (usually) hydraulic brute force to push the pile in; doing it like this requires Big Science but has the advantage of being relatively quiet and kind to nearby foundations and people.For driving smaller pilings or for shoring trenches, the bucket of a digger can be used to good effect. Just raise it up and bring it down hard.

Spun Pile is the pile that they produced at the factory and bring it to the worksite.It is almost the same with Bored Pile,but in side is hole.
It means, "pile." It could mean a pile of wool, a pile driven into the ground, a Voltaic pile (battery), or an atomic pile (nuclear reactor).
When power is applied to the armature coil, the armature which has the hammer attached to it is drawn into the coil. The bell is struck by the hammer. At the end of the hammer stroke there is a N.C. (normally closed) contact which is opened. The opening of the contacts stops the current flow to the armature coil and the armature and hammer return to the off bell position. In the off bell position the N.C. contact re closes and the cycle is repeated over again. This cycling will continue until the bell circuit is turned off.
A pile show is a piece of metal that goes onto the end of a pile. It is used to aid the pile when it penetrates dirt, and it also protects that pile while it is driving.
A skirt pile can refer to a pile of clothing in a female's dressing room. Also, a skirt pile can be a pile of dirt or rocks that are pushed to the side when clearing with large equipment.
