How does a foundation piling rig work and what types are there?

Principle of piling machine: it is a piling machinery that uses impact force to penetrate the pile into the ground. Construction of pile driver: it is composed of pile hammer, pile frame and accessory equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame, and lifted by lifting hook. The pile frame is a steel tower with a winch at the rear for lifting the pile and the pile hammer. In front of the pile frame, there is a guide frame consisting of two guide rods, which is used to control the direction of pile driving so that the piles can be accurately driven into the ground according to the designed orientation. The tower and the guide frame can be deflected together to drive inclined piles. The guide frame can also be extended downward along the tower to drive underwater piles along embankments or piers. The piling frame can be rotated and moved. The basic technical parameters of a pile driver are the weight of the impacting part, the kinetic energy of the impact and the frequency of the impact. Piling hammers can be classified into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. according to the power source of movement. Types of Pile Driving Machines: Pile Driving Machines also have Rotary Pile Driving Machines, which are used to dig into the ground with a screw and then fill the piles. Types of Pile Drivers: (1) Steam Hammer Pile Driver. Using high pressure steam to lift up the hammer head, and then rely on the self-weight of the hammer head to impact downward on the pile head, so that the pile is sunk into the ground. (2) Diesel hammer pile driver. Using fuel explosion to push the piston and impact the pile head by explosion force to sink the pile into the ground, which is suitable for driving all kinds of prefabricated piles. (3) Vibratory Hammer Pile Driver. Utilizing the mechanical vibration force of pile hammer to sink the piles into the ground, suitable for precast concrete piles and steel sheet piles with small load bearing. (4) Static pile driver.
