Pile driving is an essential part of the dock building process, which involves driving piles made of varied materials like concrete, timber, or steel piles into the soil. This is important because the piles provide vital dock support.
Consequently, there are various types of pile driving equipment. Here is a list of several types of equipment, with their individual features:
Different types of pile driving equipment
Piling rigs are necessary for drilling piles on surfaces like soil and clay. It comprises a rigid box placed on the base of a crane. It comes with additional features that help to dig into the ground.
Piling rigs can be used for multiple purposes and can be fitted with different kits. These kits are used for multiple foundations and geotechnical construction methods.
The standard features you can expect to find in these types of pile driving equipment include:
- A 360-degree rearview camera for improved operator efficiency
- Mechanical, electrical, and hydraulic system integration
- Emergency stop option to use where required
- A Boom micro-switch which provides for a better stability limit control
- Interlocking bars for more potent pulling force when used in challenging terrains
- A parallelogram that is vital for precise pile positioning
Rotary drilling rig
A rotary drilling rig is used to cut or crush through sub surfaces. Thus, it is possible thanks to downward pressure, and the combined effects of a sharp, rotating drill bit.
Additionally, the impact force the above-ground or down-hole impact hammer supplies to the drill bit helps the rig drill deeper and wider holes.
The features of a rotary drilling rig worth mentioning include:
- A short leader system for use in shallow construction sites
- The presence of modularly constructed leaders and counterweights
- The presence of strong, lightly designed steel Kelly bar tubes
- Tailored, large, spaced pumps and valves that are easy to maintain
- Special drilling attachment for use with anti-seismic piles
- Modern air-conditioning that improves the operator’s comfort through better airflow
- Control system with multiple program and control options
- Providing the operator with optimized vision field and noise protection
Hydraulic impact pile hammer
Hydraulic impact pile hammers are applicable for many pile driving operations. Furthermore, they are handy for driving sheets, steel tubes, and diverse types of piles.
It is thanks to its adjustable ram weight, blow, and stroke rates that you can experience exceptional pile driving performance in any condition.
Besides, these hammers can either be freely suspended or mounted on different piling leaders. This arrangement thus makes it convenient to mount leaders on piling rigs, piling cranes, and suspended cranes.
The hammer’s various features include:
- The option to adjust hammer impact strokes and frequency
- Easy connection to different types of hydraulic systems
- Drive caps for all pile sizes and types
- Modular ram block design
Vibratory pile hammer
Vibratory hammers use vertical vibrations to drive elements like sheet piles and pipes into the ground. While its weight helps drive components into the ground, the hammer also loosens the soil by putting adjacent soil particles into motion.
Vibratory hammers work for driving and extracting elements, for vertical drainage, and to help improve the soil’s density. Moreover, the hammer’s multiple features include:
- 360 degrees rotating gears
- A hammer brake that minimizes boom shake
- Open-loop hydraulics for improved piling efficiency
- Variable frequency, weight, and line pull
- Efficient piston motors with a bent axis
- Clamping devices that you can easily handle and adjust
Piling winches are hand control and high-speed and free-rolling machines used to hoist objects vertically while constructing docks. Then, these winches have unique features like rotating shafts, sludge pumps, tripods, chisels, and multiple casing sizes and types.
Other features worth mentioning include:
- Optimal operational efficiency
- Cone clutch with a carbon steel shaft and known for its hassle-free use
- Available in varying capacities
- The main shaft rotating
- Attached with single, double, and triple drums
Conclusion – Types of pile driving equipment for your project
It is a combination of these equipment types that work for most pile driving tasks. However, your piling contractor decides which pile driving equipment to use for each project.
And they make their choice based on factors like the soil consistency and the required depths of piles.
