So many benefits, huh? All the advantages of hydraulic pile hammers are right here!
With the rapid development of the construction industry in recent years, pile foundations have evolved from wooden piles to reinforced concrete piles or steel piles. The construction methods and machinery used for foundation work have also undergone tremendous advancements.
The principle behind the pile-driving hammer technology is that relative motion between two eccentric gears generates vertical vibrations, which separate the object being driven from the surrounding soil and reduce frictional resistance, thereby achieving the purpose of driving or extracting piles. This type of hammer features strong penetration force, excellent pile-driving quality, robustness and durability, few malfunctions, ease of use, wide power supply compatibility, and low noise levels. As a type of inertial pile-driving hammer, it can be widely used in various soil types and is primarily designed for pile-driving operations.
Application scope of pile hammers
The pile-driving hammer is a construction machinery used in foundation engineering for the construction of pile foundations, particularly for concrete bored piles. When paired with a pile frame, it can drive concrete bored piles, concrete underpinning piles (also known as "garlic-head piles"), lime piles, sand piles, and gravel piles. With the addition of a pile-clamping device, it can also drive and extract precast concrete piles and various types of steel piles. It is a commonly used piece of equipment in foundation construction for highways, bridges, airports, buildings, and other structures. Additionally, the pile-driving hammer can be utilized as a piling tool for machinery such as vibratory pipe-driven pile drivers and sheet-pile driving machines.
Composition of the pile-driving hammer
The pile-driving hammer comprises a vibration absorber and a vibrator. The vibration absorber consists of a lifting pulley, a crossbeam, a vertical shaft, and a vibration-absorbing frame. The vibration-absorbing frame is fixed to the upper part of the vibrator, with two vertical shafts mounted on each side. Each vertical shaft is fitted with a compression spring at both its upper and lower ends, forming a pair. A crossbeam is fixed to the upper part of the vertical shafts.
The vibrator consists of a motor, a housing, eccentric weights, a driving shaft, a driven shaft, and gears. The power is transmitted from the motor to the driving and driven shafts within the housing via a V-belt. The driving and driven shafts are meshed with each other through a pair of cylindrical gears. Four eccentric weights are mounted on these shafts. The lifting pulley for the product can be replaced by a lifting lug. The product also includes an electrical system that is integrated with the electrical components of the pile-driving frame. Alternatively, the product’s electrical system can be configured separately.
Pile Hammer Features
1. The pile-driving hammer is an environmentally friendly piling machine. Compared with electric hammers and diesel hammers, the high-frequency hydraulic pile-driving hammer produces less vibration and noise during operation, causing minimal disturbance to residents. If equipped with a noise-reduction power box, it generates virtually no noise at all during operation, making it ideal for construction in urban areas, densely populated regions, and locations with strict environmental restrictions.
2. The pile-driving hammer is a highly efficient piling machine. Generally, the construction efficiency of a high-frequency hydraulic pile-driving hammer is ten times that of conventional piling machinery. Its vibration-driven pile-driving speed typically ranges from 4 to 7 meters per minute; in non-clay geological conditions, the speed can reach up to 12 meters per minute. When used in conjunction with a vibration-specific pile-driving frame, it can further reduce the time required for pile driving and significantly enhance work efficiency.
3. The pile-driving hammer is a versatile piling machine. A high-frequency hydraulic pile-driving hammer can not only drive and extract precast concrete pipe piles (PHC piles), various types of steel sheet piles, and steel casing tubes, but also be used for constructing vibratory bored piles, thin-walled cutoff walls, surface compaction, deep compaction works, and tubular piles. Tubular piles represent a new piling technology with great potential for application and widespread adoption in the field of pile foundations. Using a high-frequency hydraulic pile-driving hammer to construct tubular piles is currently an economical, efficient, and environmentally friendly piling method. It is more effective, more environmentally friendly, and more energy-efficient than the current method of constructing bored piles using rotary drilling rigs.
4. The pile-driving hammer is a relatively lightweight piling machine. Compared with static hydraulic pile drivers, under the same working conditions, the total operating weight of a high-frequency hydraulic pile-driving hammer is only one-twentieth that of a static hydraulic pile driver. Moreover, the entire equipment set requires only two medium-sized trucks for transportation, making it extremely convenient to move between job sites during construction.
5. The pile-driving hammer is a piling machine suitable for a wide range of geological conditions. High-frequency hydraulic pile-driving hammers are available in three major series: conventional, high-frequency, and resonance-free. Depending on the geological conditions and project requirements, different series and varying excitation forces of high-frequency hydraulic pile-driving hammers can be selected as construction equipment. High-frequency hydraulic pile-driving hammers demonstrate exceptional capability in penetrating geological layers such as gravel beds, sand layers, and construction debris. With the sole exception of rock formations, they can adapt to virtually any other geological condition.
