Product Description
Spiral ground piles are a new type of foundation building material, mainly composed of three parts: hot-forged pipe bodies, spiral plates and connecting flange plates. It is screwed into the ground by a dedicated device, replacing the traditional concrete foundation, with the top connected to the load. The working principle of spiral ground piles is similar to that of wooden screws. Its unique spiral shape enables it to be driven into the soil by rotation. The spiral blades come into contact with the soil and generate friction, thereby fixing the pile in the soil and providing stable support. Specifically:
1. Uplift resistance: The top bolt plate of the helical ground pile can withstand the pressure or load from above, while its helical blades resist the upward tensile force through friction with the soil, ensuring that the pile body is not pulled out.
2. Shear resistance: When the helical ground piles are screwed into the soil, shear resistance is generated between the leaves and the soil particles. This resistance can further enhance the stability of the pile body.
3. Lateral frictional resistance: During the rotation of the spiral ground pile, its blades gradually penetrate and compact the surrounding soil, thereby increasing the lateral frictional resistance and enhancing the overall load-bearing capacity.
Performance Advantages
1. Easy construction: No need for ground leveling, waste soil treatment or excavation. It can be directly rotated and screwed into the ground. The construction period is short and it is less affected by the environment.
2. Good environmental performance: During the construction process, it does not damage the soil structure, reduces construction waste, and has low construction noise and vibration.
3. Low cost: Compared with traditional concrete foundations, the material and labor costs of spiral ground piles can be saved by two-thirds.
4. All-weather construction: It can be constructed under most climatic conditions, such as rain, snow, freezing and other weather conditions.
5. Removable and recyclable: After use, it can be reversed and pulled out to restore the site and reduce the impact on the environment.
6. High load-bearing capacity: Strong uplift resistance and insertion grip, which can effectively disperse pressure and reduce the risk of settlement.
7. Wide range of application: It is suitable for various geological conditions, such as silty clay, silt clay, silt soil, medium and fine sand, etc.
Applications
With the development of technology and the expansion of application fields, the market demand for spiral ground piles continues to grow. Its wide application in fields such as photovoltaic power stations, agricultural greenhouses, wooden house and integrated house foundations, street lamp foundations, signal sign foundation foundations, municipal facilities, transportation facilities, and power tower foundation foundations demonstrates its great potential as an efficient, environmentally friendly and economical basic building material

Operating Principle
Spiral ground piles are a form of deep foundation that provides support by utilizing the frictional force and end-bearing force between spiral blades and the foundation soil.
Working principle: The helical ground pile rotates the pile body into the soil layer of the foundation. As the pile body goes deeper, the contact area between the helical blades and the soil gradually increases, thereby generating a large lateral frictional resistance and end bearing force to support the load of the superstructure.
Anchoring principle: During the rotation of the ground pile, the helical blades cut the soil and cause local shear failure and displacement, forming a certain range of plastic deformation zone in the soil around the pile. This results in a relatively tight interlocking and embedding effect between the soil and the pile body, providing a strong uplift resistance.
Force transmission path: When under load, the load of the superstructure is transferred from the pile top to the pile body of the helical ground pile, then from the pile body to the helical blades, and finally transferred to the foundation soil layer through the frictional force between the helical blades and the soil and the end bearing force, thereby effectively supporting the superstructure.
