Prefabricated Galvanized Steel Round Spiral Ground Anchor Helical Screw Piles

Product Description

Helical piles, which are sometimes referred to as helical piers, helical anchors, and posts, are a screw-in pile used to build deep foundation systems and ground anchoring systems. A helical pile consists of a central shaft (circular or square) and a helix plate(s). The shaft can come in either a circular or a square cross section shape and is typically hollow.The helix plates which are press-formed with a predetermined pitch to resemble a screw are welded to the shaft. They are fabricated in various sizes and configurations to meet different types of loading and logistical requirements. The size and configuration of a helical pile is based on the design load the pile will carry, the existing soil conditions, the corrosiveness of the existing soils and the service life of the structure.
A helical piers is like a big screw with a shaft and bearing plates. Soil conditions and loads determine the necessary depth of the pier and diameter of the helixes, or bearing plates. Helixes are only found on the lead section of the pier, and extensions are added when needed to drive the pier deeper. Bearing capacity can be verified by the amount of torque required to drive the pier during installation. At the top of the pier is a cap to which various heads can be attached. Usually welded to the cap or somewhere along the shaft, the head may be a bracket that can be bolted to a foundation, like the ones shown here, or it could be a base for a deck post, for example.

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

Spiral ground piles are a new type of foundation building material, featuring convenient construction, low cost, environmental friendliness, and recyclability. They are widely used in various fields. Here are some common application scenarios:
In the field of architecture:
1.Modular buildings: Can serve as the basic support for modular houses, mobile homes, container houses, etc. Construction is fast, adaptable to different terrain conditions, and easy to relocate and recycle.
2.Light steel houses: Provide a stable foundation for light steel houses. Their tensile pull-out force and insertion grip force can ensure the stability of the house in various environments.
3.Wooden villas: Used for the foundation construction of wooden villas, matching the wooden structure, easy to install, and more harmonious with the natural environment in appearance.
In the energy sector:
1.Solar energy projects: It is one of the preferred base materials for solar farms, ground-mounted solar power stations, photovoltaic carports and other solar projects. Spiral ground piles have a fast construction speed, cause little damage to the ground, and can quickly complete the installation of solar panel supports, ensuring the stability and service life of solar panels.
2.Wind power generation: In the installation of wind turbines, spiral ground piles serve as the foundation support for wind turbines, capable of withstanding strong winds and the weight of large wind turbines, ensuring the stable operation of wind power equipment.
In the field of transportation facilities:
3.Highway and railway construction: It is used as the supporting foundation for traffic facilities such as guardrails and signboards along highways and railways. It is convenient for construction and can be installed quickly to ensure traffic safety.
4.Pedestrian bridges and boardwalks: As the supporting foundation for pedestrian bridges and boardwalks, it has a simple structure, a short construction period, and a small environmental impact, and can be well integrated into the natural landscape.
In the field of landscape architecture:
1.Outdoor landscape facilities: Spiral ground piles are used for supporting outdoor seating, lamp posts, flower racks and other landscape facilities. They are easy to install, can be flexibly arranged according to landscape design, and cause little damage to the surrounding environment.
2.Garden architecture: In the foundation construction of pavilions, pergolas and other garden buildings, spiral ground piles can provide stable support while reducing the damage to garden vegetation during construction.
Temporary facilities field
3.Construction sites: At construction sites, helical ground anchors can be used to build the foundations of temporary worker sheds, fences, and other facilities. They are easy to install and remove, can be reused, and save costs.
4.Campsites, music festivals, etc.: Provide stable support for tents, marquees, and other temporary buildings, facilitating quick setup and dismantling, and meeting the needs of various temporary events.
Other fields
1.Agricultural facilities: Used for the basic construction of agricultural facilities such as fruit and vegetable greenhouses and breeding sheds, it can be quickly installed, adapt to different terrains and soil conditions, and have a small impact on the agricultural production environment.
2.Advertising boards, communication base stations: As the supporting foundation for facilities such as advertising boards and communication base stations, its wind resistance and stability can ensure the safe operation of the facilities, and at the same time, the construction is convenient and not restricted by seasons and weather.
