What Are The Advantages Of A Hydraulic Vibratory Pile Driver?
A pile driver consists of a pile hammer, a pile frame, and auxiliary equipment.hydraulic vibro hammer is attached between two parallel vertical swinging arms (generally called a gantry) at the front of the pile frame and lifted by a hook. The pile frame is a steel structure tower with a crane at the rear for lifting piles and vibratory hammer for excavator. There are two swinging arms at the front of the pile frame to control the direction of the pile, ensuring the pile enters the ground clearly according to the design direction. The basic performance parameters of a pile driver are the weight of the impact part, the impact kinetic energy, and the impact frequency. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic vibratory hammer, etc.
excavator vibratory pile hammer is a new type of pile driver driven by hydraulic pressure, which can adjust the hydraulic pressure according to different geological structures and soil layers to achieve a reasonable impact force. Large, medium, and small hydraulic pile drivers are commonly used for road guardrail piling and highway guardrail infrastructure construction. Similar piling machinery and equipment include: hydraulic pile drivers, road piling machines, guardrail piling machines, and road drilling equipment. Compared with diesel pile drivers, the assimilation rate of vibro hammer for excavator can reach 70%~95%, while that of diesel pile drivers is only 20%~30%. Hydraulic pile drivers have accurate piling control and can complete piling work in different geological structures; excavator mounted vibratory hammers demonstrates excellent performance in noise reduction, vibration, and noise, making it particularly suitable for large-scale urban engineering construction.vibro hammer excavator has significant energy-saving and emission-reduction effects and is a popular trend in the future development of pile hammers.
(1) The impact force can be effectively selected according to the compressive strength of the soil and pile material, ensuring full utilization of impact kinetic energy without damaging the pile body and saving on pile cushions during construction.
(2) Under the premise of piling, the lower impact force and penetration depth indicators can be obtained simultaneously, thus scientifically determining whether the pile has entered the predetermined soil layer.
(3) Features of hydraulic pile hammers: suitable for inclined pile work and water pile foundation construction, hydraulic pile hammers do not have difficulty starting in soft ground conditions, and can operate in various climates.
(4) The impact kinetic energy can be greatly increased. (5) Hydraulic vibratory pile drivers produce minimal pollution, with mostly no exhaust emissions, and impact noise is approximately 20 dB lower than other pile drivers.
Hydraulic vibratory pile drivers can be used for pile driving and compaction and are widely used in pile foundation construction sites. They are suitable for steel sheet piles, steel pipe piles, H-beam piles, precast piles, and other pile foundation work. The working method of the hydraulic vibratory pile driver is compatible with various fixed and mobile pile driving rigs, and it can also be directly lifted by a crane, making replacement convenient. Compared with traditional diesel impact hammers, hydraulic vibratory pile drivers have the following advantages: 1. Low noise. No exhaust emissions. Environmentally friendly. 2. Simple operation. High level of automation. 3. Suitable for various pile types. 4. Widely used in construction, bridges, ports, transportation, railways, marine engineering, and other construction sites.
The target of hydraulic vibratory pile drivers is typically cast-in-place piles, including precast reinforced concrete piles, steel sheet piles, and H-beams. Precast reinforced concrete piles are widely used in building foundation engineering, including factories, high-rise buildings, and large and medium-sized highway bridges. Steel sheet piles are mainly used in foundation engineering for large and medium-sized factories, high-rise buildings, deep-water docks, and offshore wind power. H-beams are cold-rolled in factories and are suitable for very soft soil layers. In addition to being used as foundations for buildings, they can also be used as support piles for foundation pits. Hydraulic vibratory pile drivers are widely used in these types of construction industries.
