Earth Screws
Honor Energy is manufacturer in solar mounting system who is producing Earth Screws.It has larger spiral blades, enabling it to effectively rotate into the ground, reducing soil disturbance and increasing the stability of the ground piles. The spiral ground pile design eliminates the need for extensive excavation during installation, greatly reducing the impact on the environment.
Earth Screws are a high-bearing foundation structure designed specifically for soft soils. Their core feature is a widened spiral blade with a diameter of 300-600 mm, which increases the contact area with the soil, thereby enhancing pullout resistance and stability. These piles are suitable for low-bearing soil conditions such as sand and silt, effectively preventing the supporting structure from sinking or tilting.
Technical Specifications
| Parameter | Specification | Note |
| Pipe Diameter | 60-127mm | Larger diameter of Earth Screws for solar provides higher load capacity.(Normally 76mm) |
| Total Length | 1200-3500mm | Determined by ground conditions and frost depth.(Normally 1600-2500mm) |
| Wall Thickness | 2.5mm-4mm | Affects shear strength and bending resistance.(Normally 2.75-3.5mm) |
| Helix Diameter | 176-250mm | Wider helix increases soil contact area and pullout resistance. |
| Helix Thickness | 4-6mm | Usually thicker than pipe wall to prevent deformation during installation. |
| Surface Treatment | Hot-dip galvanized | Must be hot-dip galvanized. Electroplating is not allowed (too thin). |
| Coating Thickness | Average ≥80–85μm, Local ≥60μm | For coastal or corrosive environments, increase to ≥100μm. |
How are products packaged?
We have pallet for 1700*1050*1150mm and 84 screws one pallet for screw earth.
Product Advantages
Earth screw foundation is an innovative solution for solar power plant foundation engineering, featuring enlarged spiral blades with diameters ranging from 400-800 mm.
1. It increases the contact area with the soil, easily adapting to soft soil conditions and providing stable support for solar mounting systems.
2. Utilizing specialized machinery, it achieves high pile driving speeds, capable of installing nearly 100 piles per day.
3. We hold CE, JIS, and ISO certifications, ensuring reliable quality.
Connection method
Ground earth screws for solar is mainly secured through nut and bolt connections and connected to the upper components. The main features of nut connections are simple structure, simple manufacturing process, low cost, convenient up-and-down adjustment, and a wide range of up-and-down adjustment. They are widely used in photovoltaic power stations, guardrails, billboards, traffic, and other infrastructure projects.
