Talking about pile drivers, not everyone is familiar with them. This is a common engineering team, which is a kind of pile driver that uses impact force to penetrate piles into the ground. It consists of a pile hammer, a pile frame, and lower configurations. The pile hammer is connected between two parallel vertical guide rods (commonly known as a gantry) at the front of the pile frame and is lifted by a hook. The chimney frame is a steel-designed tower, and a hoist is provided at the back of the chimney to lift the chimney and hammer. In front of the battery frame, there is a guide frame made of two guide rods, used to control the offset of the battery, thereby accurately penetrating the battery into the ground according to the planned direction. The tower and guide frame can be turned together to tilt the battery. The guide frame can also extend down along the tower frame to drive underwater batteries along embankments or docks. The scaffold can rotate and move. The basic skill parameters of the pile driver are the weight of the attacking department, the kinetic energy of the attack, and the frequency of the attack. Based on the source of motion energy, pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. In ancient China, engineering was manually constructed, and the pile foundation was manually constructed. With the development of the times, mechanical equipment has become more and more perfect. Engineering pile drivers have been used in many projects. Although pile drivers are very popular, many people have only heard of this type of mechanical equipment and don't particularly know about it.

1. Spiral Pile Driver

The spiral pile machine is mainly composed of a power head, drill rod, column, crawler-style hydraulic chassis, rotating structure, hoist, operating room, electrical system, hydraulic system, and transportation mechanism. In the operating state, when operating the hydraulic system, it can align the movement, turning, lifting column, and pile stacking. In the work process, the motor head drives the drill rod, the drill bit rotates, and the crane controls the lifting of the drill tool. The soil material cut by the drill bit is transported to the ground through the spiral blades. By drilling to the designed depth to form a hole, according to the requirements of the construction method, you can also stack concrete while injecting concrete (or mud).

2. Diesel Hammer Pile Driver

The main body of the pile driver's diesel hammer also includes a cylinder and a plunger. Its working principle is similar to a two-stroke single-cylinder diesel engine. The atomized diesel injected into the cylinder combustion chamber is driven by the strong pressure generated by the high pressure and high temperature explosion to operate the hammerhead. Diesel hammers are divided into two types: guide rod type and barrel type. The cylindrical diesel hammer uses the alternating movement of the core (upper piston or impact body) to hammer the pile. The two-line diesel hammer has a fixed piston, and the cylinder acts as the impact body for the impact battery due to its hammering energy. The lifespan has been gradually eliminated. Now widely used is the cylindrical hammer for diesel piles. Especially, in recent years, diesel hammers have been divided into four speeds, with the first speed being the smallest and the fourth speed being the largest. Usually, 2 to 3 speeds are used when handling batteries. It is easy for operators to understand and can also be estimated by touch energy.

3. Plug-in Machine

The plug-in machine is a new type of machine pile driver, mainly used in the field of coastal soft foundation treatment and maritime construction. After the plate inserter is in place, it sinks by aligning the jack with the vibrating hammer. The drainage plate passes through the casing and is connected to the anchor boot at the end. The casing is placed close to the anchor boot to insert the drainage plate to the designed depth of the floor. After the pipe, the anchor boot and the drainage plate are left on the ground together, and then the continuous drainage plate is cut to complete the insertion operation of the drainage hole. The popular plug-in machines in the world today are fully utilizing their advantages. Weak alkali must be treated before use, so the plug-in machine will have its place in the future construction industry.

4. Vibrating Hammer

The vibrating hammer is a device that generates strong excitation force to push objects into the ground. The electric motor drives a pair of eccentric blocks to rotate in opposite directions so that the lateral centrifugal forces generated by them cancel each other out, and the vertical centrifugal forces overlap each other. The vibrating pile hammer is a pile foundation construction machinery used in construction engineering for the construction of concrete piles. After supporting the pile frame, you can sink concrete piles, expanded concrete piles at the bottom (garlic head piles), lime piles, sand piles, and crushed stone piles; when equipped with a pile clamp, it can sink and remove precast concrete piles and several steel piles. It is the ideal equipment for roads, bridges
