SPA5 Plus 2650mm Hydraulic Concrete Pile Head Cutter Machine
SPA5 Plus pile cutter is fully hydraulic, the diameter range of
pile cutting is 250-2650mm, its power source can be hydraulic pump
station or mobile machinery such as excavator. The SPA5 Plus pile
cutter is modular and easy to assemble, disassemble and operate.
With the development of economy, the traditional piling technology
of manual cooperating with air picks can no longer meet the needs
of the construction of pile foundations such as bridges and
roadbeds. Therefore, the hydraulic pile cutter construction method
came into being. Hydraulic pile cutters have obvious advantages in
saving labor and ensuring construction safety and quality; and
using this construction method can also reduce the generation of
occupational disease hazards such as noise and dust, which is
conducive to ensuring the safety of workers and meets the
development requirements of modern production.
Applications: It is suitable for chiseling of various round and square pile
heads with pile diameter of 0.8~2.5m and concrete strength ≤ C60,
especially for projects with high requirements for construction
period, dust and noise disturbance.
Process principle: The power source of hydraulic pile cutting machine generally
adopts fixed pump station or movable construction machinery (such
as excavator).
Pile cutting:
According to the site construction conditions, use the truck
mounted crane to move the pile cutter to the pile head to be cut,
adjust the height of the pile cutter to the appropriate pile
cutting position, use the remote control equipment to clamp the
pile surface to be cut, adjust the system pressure according to the
concrete strength, and pressurize the oil cylinder until the pile
body breaks under strong pressure.
After the pile shaft is cut off, the concrete block is directly
lifted by the platform lifting force, and the broken pile block is
moved to the designated position. The cycle shall be conducted
until the design height of pile top. When the pile is cut to the
top of the reinforcement cage, the lower pressure shall be used
first, and the squeezing depth of the drill rod shall be adjusted
according to the actual thickness of the protective layer. The
protective layer shall be broken to make the anchor bars at the
pile head leak out, and then the position of the pile cutting drill
rod shall be adjusted. The pile body shall be cut off with a larger
squeezing force to avoid damage to the reinforcement.

Main characteristics and advantages of pile cutter:
1. High pile cutting efficiency.
A piece of equipment can break 40~50 pile heads in 8 hours of
continuous operation, while a worker can only break 2 pile heads in
8 hours, and for pile foundations with concrete strength greater
than C35, at most 1 pile per day can be broken
2. The pile cutting operation is low-carbon and environmentally
friendly.
The construction machinery is fully hydraulically driven, with low
noise, no disturbance to the people, and low dust hazard.
3. The pile cutter has high versatility.
The modular design of the pile cutter can adapt to the needs of
various types of pile diameters and concrete strength changes in
the field by adjusting the number of modules and hydraulic
strength; the modules are connected by pins, which are easy to
maintain; the power sources are diversified, according to the site
conditions. It can be equipped with excavator or hydraulic system:
it can truly realize the versatility and economy of the product;
the design of retractable hanging chain can meet the requirements
of multi-terrain construction operations.
4. The pile cutter is easy to operate and has high safety.
The pile cutting operation is mainly operated by the remote control
of the construction manipulator, and there is no need for workers
near the pile cutting, so the construction is very safe; the
manipulator only needs to pass a simple training to work.
