[0002] Punching pile driver is an indispensable mechanical equipment in the construction of bridges, docks, roads, railways and other building foundations. Punching pile driver consists of hammer head, pile frame and auxiliary equipment. The hammer head is attached between the two vertical guide rods in front of the pile frame to lift the hook. The two vertical guide rods are commonly known as gantry. The pile frame is a steel structure tower with a winch at the rear to lift the pile and hammer head. When punching the pile driver, the winch is used to drive a hammer head of a certain weight to lift the hammer head within the set height, and then release it to let the hammer head fall freely, using the impact kinetic energy to impact the soil layer or break the rock layer to form a pile hole.
