There are many modern pile foundation construction projects, offering a wide range of choices in excavators and pile driving equipment to adapt to different construction conditions. Today, we will discuss the application of static pile drivers in construction, which has specific requirements:

Generally speaking, considering construction efficiency, pile driving quality, and overall economic efficiency, excavator pile drivers are suitable for both hydraulic and vibratory pile driving.

Traditional pile drivers consist of a pile hammer, pile frame, and auxiliary equipment. The pile hammer is installed between two parallel vertical guide rods (commonly known as gantry) at the front of the pile frame and is lifted by a hook. The pile frame is a steel structure tower, with a pile winch and pile hammer at the rear. The front of the pile frame has a guide frame composed of two guide rods to control the piling direction, ensuring the pile is driven accurately into the soil according to the design. The basic technical parameters of a pile driver include the weight of the impact part, impact energy, and impact frequency. According to the power source of the movement, pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc.

Excavator pile drivers use static pressure (the weight of the pile driver and counterweight) to press prefabricated piles into the soil section by section. This method saves steel and concrete, reducing project costs. Compared to the hammering method, the concrete strength grade can be reduced by 1-2 levels, and steel reinforcement can be saved by about 40%. The construction process is free of noise, vibration, and pollution, causing minimal disturbance to the surrounding environment. It is suitable for soft soil areas, densely populated areas, city centers, and precision factory expansion projects.

Many construction teams focus solely on the price of drilling projects and quick capital recovery, neglecting geological conditions, construction plans, team strength, and management methods. This leads to heavy and chaotic construction processes, and even failures such as hole collapse, sedimentation, and slipping. Clearly, this approach is undesirable as it severely affects project progress, team reputation, and the development of construction enterprises.
