Product Description
The circular helical pile is a deep foundation solution, consisting of a circular steel shaft with spiral blades. It is inserted into the ground using hydraulic equipment, and the support force is provided by the contact between the spiral blades and the soil. It is used to stabilize and support various structures. Its circular cross-sectional design enables it to perform well in terms of compressive strength and buckling resistance, and is particularly suitable for applications requiring high lateral stability and compressive strength. 
Performance Features
High compressive and flexural resistance: The circular cross-section has a higher moment of inertia, which effectively resists compressive forces and buckling.
Quick installation: Installed by rotating into the ground using hydraulic equipment, no excavation or concrete pouring is required. The installation process is fast, and it can immediately bear weight.
Strong adaptability: Suitable for various soil conditions, including soft soil, sandy soil, and clay, and can penetrate into stable soil layers or bedrock.
Environmentally friendly and vibration-free: No vibration is generated during installation, causing little interference to the surrounding environment, making it suitable for use in sensitive areas.
Durability: The surface is treated with hot-dip galvanizing, providing strong corrosion resistance and a long service life.
Adjustable and reusable: Installation depth can be adjusted as needed, and it can be reused after removal.
Application fields
- Building foundation: Used for the support of new residential buildings, commercial buildings and high-rise buildings.
- Solar system: Provides a stable support base for solar photovoltaic power stations.
- Foundation repair: Used for repairing subsidence or aging foundations.
- Transportation facilities: Supports street lamps, traffic signs, billboards, etc.
- Industrial facilities: Used for mechanical foundations, equipment support, etc.
- Garden landscape: Used for gardens, landscape buildings, flagpoles, etc. foundations.
Parameters
- Materials:
High-strength steel, hot-dip galvanizing treatment.
- Dimensions:
Outer diameter: 2.875 inches (73 millimeters) to 4.5 inches (114 millimeters).
Wall thickness: 0.203 inches (5 millimeters) to 0.337 inches (9 millimeters).
Length: Customizable as needed, usually ranging from 5 to 10 feet.
- Spiral blades:
Diameter: Choose as needed, typically 1 - 2 feet.
Quantity: 1 - 4 blades.
- Load-bearing capacity:
Compressive strength: Up to 150 thousand pounds (667 thousand newtons).
Tensile strength: Depending on soil conditions and design, can reach several tons.
Installation equipment: Requires hydraulic equipment or handheld tools.
The parameter selection of spiral ground piles should be combined with engineering requirements, geological conditions and budget, and the shaft diameter, blade size and material should be reasonably matched. Its modular design gives it obvious advantages in terms of load-bearing capacity, construction efficiency and environmental protection, and it is suitable for a variety of scenarios ranging from temporary facilities to permanent buildings.
