Diesel pile driver

The main body of the diesel hammer pile driver 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 hammer is driven to work by the powerful pressure generated by the combustion and explosion of atomized diesel injected into the cylinder combustion chamber under high pressure and high temperature. Diesel hammers are divided into guide rod type and barrel type according to their structural forms. The guide rod diesel hammer uses the plunger as the hammer seat to press on the pile cap, and uses the cylinder as the hammer head to lift along the two guide rods.

2. Common application of diesel pile driver

A piling machine that penetrates a pile into the stratum with impact force. It is composed of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached between two parallel vertical guide rods (commonly known as the gantry) in the front of the pile frame and lifted with a lifting hook. The pile frame is a steel structure tower, and a winch is set at its rear to lift the pile and pile hammer. In front of the pile frame, there is a guide frame composed of two guide rods to control the driving direction and make the pile penetrate into the stratum accurately according to the design orientation. The tower and 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 the embankment or wharf. The pile frame can rotate and move. The basic technical parameters of the pile driver are the impact weight, impact kinetic energy and impact frequency. The pile hammer can be divided into drop hammer, steam hammer, diesel hammer, hydraulic hammer, etc. according to the power source of movement.

3. Development history of diesel pile driver

The pile hammer of drop hammer pile driver is a heavy steel block, which is lifted by a winch with a hook. After uncoupling, it drops freely along the guide frame. The pile hammer of steam hammer pile driver consists of a hammer head and a hammer seat, which is powered by steam or compressed air. There are two types of single acting steam hammer and double acting steam hammer. The single acting steam hammer uses the plunger or cylinder as the hammer head. The steam drives the hammer head to rise and then let it fall along the guide rod of the hammer seat to drive the pile. The double acting steam hammer generally uses the weighted plunger as the hammer head, and the cylinder as the hammer seat. The steam drives the hammer head to rise, and then drives the hammer head to impact the pile downward. The speed of up and down reciprocation is fast and the frequency is high, which makes the pile vibrate when penetrating into the stratum, which can reduce the friction resistance, and the pile driving effect is good. The differential steam hammer with bi-directional unequal force has light weight of hammer seat, relatively increased effective impact weight and better performance. The reversing of the steam hammer inlet and exhaust rotary valve can be manually controlled, or automatically controlled by the flange control lever installed on the side of the hammer head and rising and falling with the hammer head. Both methods can adjust the impact stroke of the steam hammer.
