The excavator vibratory pile driver is composed of pile hammers, jibs, clamp nozzles and other equipment. It uses its high-frequency vibration to vibrate the pile body with high acceleration, and transmits the vertical vibration generated by the machine to the pile body. The vibration sinking claw hammer and the weight of the pile body sink the pile into the soil. When pulling out the pile, pull up the pile with the lifting force of the excavator while one side is vibrating.
Excavator piling construction is to use different types of piling equipment and excavator installation combination, which can be suitable for all the needs of various work sites. Different types, only need to replace the chuck, that can meet the user's construction needs. There are also differences in the construction methods of pile driving, pressing, vibrating or screwing into the foundation soil of various materials, and the commonly used methods are hammering, vibration, water jetting and pile pressing.
Hammering method and vibration method are common application methods in foundation construction. The hammering method is to use the impact energy of the pile hammer of the excavator to overcome the resistance of the foundation soil to the pile, and to drive the pile to a predetermined depth, which is suitable for soft plastic or plastic cohesive soil. The main equipment used is pile frame, pile hammer, power equipment, etc.
