In modern pile foundation construction projects, to ensure the height of concrete piles meets construction requirements, it is typically necessary to expose the pile 1-2 meters above the ground. This necessitates cutting off the excess portion of the pile. Hydraulic pile breakers are the most professional pile-breaking equipment for efficiently and safely completing this task.
I. What is a Hydraulic Pile Breaker?
A pile breaker is a modular device, with each module equipped with an independent hydraulic cylinder and chisel. The hydraulic cylinder drives the chisel in a linear motion, and the parallel connection via hydraulic hoses enables synchronous operation. This allows for multi-point crushing and breaking of piles with the same cross-section, cutting off pile heads of different diameters.
Pile breakers are available in three series: Round pile breakers(like Sinovo SPA series）, Square pile breakers (like Sinovo SPF series) and Irregular shape pile breaker (like Sinovo wall breaker, Coral type Grab etc). Generally, round pile breakers are suitable for pile diameters of 250mm-3000mm; square pile breakers are suitable for pile side lengths of 300mm-600mm, meeting the requirements of various large-scale foundation construction projects.
Allowing for variations in module combinations to accommodate different pile diameters, Piles breaker can be freely connected to various engineering machinery, and its telescopic chain-type design is suitable for integral pile head crushing operations.By fast-connecting the main and auxiliary pin shafts, different modules can be assembled to form pile cutters of various sizes, offering great flexibility and convenience.
II. What are the advantages of a pile breaker?
During construction, pile breakers are simple to operate, highly efficient, low-noise, low-cost, safe, and reliable. They exert no impact on the pile itself and have no effect on its bearing capacity. They also significantly shorten the construction period, making them a piece of equipment strongly promoted by the authority of building,Construction and supervision departments. They are suitable for pile group construction projects.
1. Environmental friendliness: The fully hydraulic drive enables low-noise operation during pile head construction, without affecting the surrounding environment. Hydrostatic radial construction has no impact on the parent pile or equipment.
2. Low cost: The operating system is simple and convenient, requiring only one or two operators and one excavator, saving manpower and controlling costs.
3. Multifunctionality: For example, Sinovo SPF400 square pile breaker is modular and can be combined in different ways to break both round and square piles, offering dual functionality.
4. Compact size: Lightweight and easy to transport.
5. Safety: Construction personnel do not come into contact with the construction site, adapting to the safety requirements of complex terrain.
6. Versatility: Diverse power sources allow for flexible connection to excavators or hydraulic systems depending on site conditions, enabling seamless integration with various construction machinery. This ensures true versatility and economy. The telescopic chain hoist design meets the requirements of multi-terrain construction operations. Or the additional hydraulic power station can support the pile breaker to be suspended by the crawler crane to carry out long-distance construction work.
7. Long Service Life: Manufactured using military-grade materials from a top-tier supplier, ensuring reliable quality and a longer service life.
8. Convenience: Compact size and easy transportation. The simple modular design allows for easy replacement of modules to accommodate different pile diameters. Modular reassembly is simple and convenient.
III. Key Point of election Hydraulic Pile breaker
How to select the right pile breaker for your engineering project? First, determine the pile diameter, then identify the cement grade. Next, calculate the crushing force required to break the concrete pile. The breaker must exert a force greater than the concrete’s strength to split it, allowing the crack to propagate inward and ultimately fracture the entire cross-section. Such as the max pressure force of Sinovo SPA8 round pile breaker reach to 790 kN,which can break C70 grade concrete. In the process of splitting, the front end of the chisel cannot be designed as a sharp surface, which results in the failure to break or cut the rebars entangled in the concrete. For instance, SINOVO‘s Chisel head features a rounded tip that not only efficiently splits concrete but also glides over rebars without causing damage.
In actual engineering practice, subcontractors often wrap plastic around the ends of rebars when the cage exceeds the elevation to reduce the grip force between cement and rebars, facilitating the removal of fractured concrete fragments.
The optimized structure of the pile breaker is designed with hydraulic cylinders installed from the head to the tail of the structural components. This configuration ensures uniform force distribution throughout the assembly during operation, fundamentally preventing fracture issues. The force transmission from the chisel tip to the connecting body and main pin significantly reduces equipment damage during construction. For instance, SINOVO pile breakers utilize high-strength alloy steel with exceptional hardness and rigidity, boasting a service life exceeding 5,000 piles. Hydraulic pile breakers are now widely adopted in major infrastructure projects worldwide, including the Changi Airport Terminal in Singapore, Vietnam’s airport projects, and large-scale pile foundation works in Indonesia, Romania, and Saudi Arabia. Their unique design and superior performance have established a solid foundation for efficient, safe, and rapid pile foundation construction, dramatically shortening pile head removal timelines and delivering substantial returns to contractors. After years of market validation, these pile breakers have earned unanimous praise from foundation contractors for their stable performance and outstanding engineering adaptability.
