Spiral pile product introduction: Efficient deep foundation solution

Ⅰ. Product Overview

Spiral pile (also known as spiral pier, spiral anchor) is a deep foundation component installed by screwing in, welded by circular/square steel shaft and spiral plate, resembling a large screw. Its design is customized based on soil conditions and load requirements, and can be installed vertically or obliquely to transfer structural loads to deep stable soil layers, replacing traditional concrete foundations. The product has passed international certifications such as API, ISO, CE, etc., and is suitable for infrastructure construction in multiple scenarios such as household, industrial, and commercial use.   

Ⅱ. Core Advantages

1.  Superior structural performance
-Strong resistance to pulling and compression: The spiral plate design forms a mechanical lock when cutting into the soil, with a tensile pulling force of up to tens of tons, suitable for high load requirements.   
-Small soil disturbance: The screw in installation reduces damage to the surrounding soil and maintains the stability of the original soil layer.   
2.  Efficient and convenient construction
-Quick installation: Single pile installation only takes a few minutes, and can complete 10-20 pieces per day, shortening the construction period by 50% compared to concrete foundations.   
-Adapt to complex environments: No need for large excavation equipment, can operate in narrow sites, slopes, high water level areas, and is not affected by rain and snow weather.   
3. Cost and environmental advantages
-Low overall cost: eliminates the need for concrete pouring, curing, and other processes, reducing material and labor costs by 30% -50%.   
-Green and sustainable: Steel is 100% recyclable, installed without noise or vibration, with minimal environmental impact, and can be disassembled and reused.   
4.  Flexible and diverse functions
-Multi directional bearing: It can vertically bear the weight of the structure, and can also be installed horizontally/obliquely for slope support and anchoring of retaining walls.   
-Instant force: After installation, there is no need to wait for curing, and it immediately has load-bearing capacity. Torque feedback can verify load performance in real time.   

Ⅲ. Application Scenarios

Ⅳ. Working principle

1.  Structural compositio
-Steel shaft: Made of Q355 steel, with a diameter of 2-7/8 "(73mm) to 8.625" (219mm), a wall thickness of 5.2-8.6mm, and a surface hot-dip galvanized (zinc layer ≥ 80 μ m) for corrosion protection.   
-Spiral plate: 8-14 inch diameter, 3/8-1/2 inch thickness, welded to the shaft body according to the pitch to form a "soil screw" structure.   
2.  Force mechanism
-When installed vertically, the spiral plate cuts into the soil layer and transmits the upper structural load to the deep stable soil layer through soil friction and bearing capacity;   
-When installing horizontally/obliquely, use the anti pull force of the spiral plate to resist the lateral pressure of the soil for anchoring or support.
