Product Description

A complete Power Shaft Assembly consists of a lead helix section, extension(s) and guy termination other attachment.  The helix size (diameter) and number of helices are selected for the required holding strength.  The shaft size and rating is selected based on the necessary holding strength and installation torque requirement.  The guy attachment is chosen based on the number of guys

Extensions with helix are placed directly after the lead section (no bare extensions in between). They are used when additional bearing area is needed and to develop increased installation torque.

Hot Dip Galvanized per ASTM A123.


Consists of solid square shafts, ranging from 1.5″ to 2″. The piles are typically used for ultimate loads between 100 and 650 kN (25-150 kips) but have been tested to loads in excess of 900 kN (200 kips) in unique situations.
Square shaft products are generally used in small to moderate loading applications, and they provide excellent tension resistance. Square shaft piles are able to penetrate dense and cobble-rich soil when compared to their helical pipe pile equivalents, but they have lower resistance to buckling and negligible lateral load resistance.
In applications where tension is the primary consideration, we recommend the Square Shaft Piers. They have several advantages over the typical square shaft anchors.
 

Spiral ground piles are a new type of foundation building material that can partially replace traditional reinforced concrete pouring construction techniques, making building foundations more flexible and fast. It saves construction costs such as ground leveling, waste soil treatment, and excavation, and can be widely used in foundation construction in various industries.

 

1. Construction advantages

Spiral ground piles are driven into the ground in a swirling manner, so the soil is not easy to loosen and can make good use of the soil's own conditions. From the blade structure of the spiral ground pile, it has good tensile strength and insertion grip.

2. Simple and efficient

As a new type of foundation technology, spiral ground piles have outstanding advantages such as easy construction, short cycle, minimal impact from construction environment, no damage to local environment, and easy migration and recovery.

3. Low cost

Compared to concrete formwork, steel reinforcement bundling, and pouring. The processes of pre embedding anchor bars, curing, demolding, and backfilling the foundation soil can save material and labor costs for spiral ground piles by simply positioning and driving them.

4. All weather construction

Construction can be carried out under most climatic conditions, such as rain, snow, freezing, etc., with minimal environmental impact.

In construction engineering, foundation is a crucial and important link, which not only reflects the quality of the project, but also relates to the stability and service life of the building. Therefore, the application of double leaf ground helical anchor in foundation engineering has become an indispensable part of the construction industry.

Double leaf ground helical anchor are undoubtedly an excellent foundation reinforcement material. double leaf ground helical anchor, as the name suggests, is composed of two rotating blades. This design not only increases the bearing capacity and shear performance of the ground pile, but also improves its stability and anti collapse ability. Its advantages also lie in its large bearing capacity, fast construction speed, low cost, convenient transportation, and better performance in dealing with various geological and climatic conditions.

In practical applications, double leaf ground helical anchor have been widely used in various foundation projects such as deep foundation pit support, subway tunnels, and bridge foundations. Especially in the case of limited urban land resources, the application of double leaf ground helical anchor can better solve spatial problems and provide strong support for urban construction. At the same time, double leaf ground helical anchors have also played an important role in earthquake disasters, reducing disaster losses and casualties.
