The pile driver uses impact force to piling the pile into the ground. It consists of pile hammer, pile frame and auxiliary equipment.
The pile driver is composed of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame, and is lifted by a lifting hook. The pile frame is a steel structure tower, and a hoist is provided at the rear thereof for lifting the pile and the pile hammer. There is a guide frame composed of two guide rods in front of the pile frame, which is used to control the direction of pile driving so that the pile can penetrate the ground accurately according to the design orientation. The basic technical parameters of a pile driver are the weight of the impact part, the impact kinetic energy, and the impact frequency. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. according to their power sources.
Drop hammer pile driver The pile hammer is a steel weight, which is lifted by a hoist with a hoist. After being unhooked, the pile will fall freely along the guide frame to pile.
Steam Hammer Pile Driver The pile hammer consists of a hammer head and a hammer seat, and is powered by steam or compressed air. There are two types of single-acting and double-acting steam hammers. The single-acting steam hammer uses a plunger or a cylinder as the hammer head, and the steam drives the hammer head to rise, and then it is allowed to fall along the guide rod of the hammer seat to pile. The double-acting steam hammer generally uses a heavy plunger as the hammer head and a cylinder as the hammer seat. The steam drives the hammer head to rise, and then drives the hammer head to impact the piling down.
Diesel hammer pile driver The main body is also composed of a cylinder and a plunger. Its working principle is similar to that of a single-cylinder two-stroke diesel engine. The atomized diesel injected into the combustion chamber of the cylinder is driven by the strong pressure generated by high pressure and high temperature explosion to drive the hammer head to work. Diesel hammer is divided into guide rod type and barrel type according to its structure.
Hydraulic hammer pile driver It is a diesel belt starter. It is driven by oil pressure and can adjust the hydraulic pressure according to the soil quality of the stratum to achieve a proper impact. It is a new type of pile driver. Small and medium-sized hydraulic pile driver, often used for piling of highway guardrails and construction of highway guardrails. Similar piling equipment includes: hydraulic pile driver, highway pile driver, guardrail pile driver, highway drilling machine.
Screw pile driver Spiral pile driver is a kind of pile driving equipment that drives the drill pipe drill bit to make holes into the underground drill through the power head. The screw pile driver can be divided into two parts: the pile frame and the drilling part.
