Large-scale industrial solar power plant facilities are typically installed on the ground. For these, pile foundations are a common engineering method, in which piles are driven directly into the ground to provide support.
In order to maximize the benefits of pile foundations, we have developed a specialized piling attachment (patent pending). Simply attached to a backhoe, it dramatically increases workability and construction speed. This revolutionary foundation engineering method is ideal for the mega-solar era.
Used with a common backhoe (available all over Japan), multiple Next Pilers can easily be driven into the ground, depending on site conditions. For example, when used to perform work concurrently at multiple construction sites, this method places fewer constraints on construction planning than other pile-driving equipment, as well as shortening construction periods and reducing costs.
With 80 or more piles driven per day, this method is fast and easy compared with screw-type methods, reducing construction cost and time. For mega-solar construction projects, the performance is impressive.
The pile foundation construction method is suited for a wide variety of ground conditions—from normal ground through to hard ground such as asphalt or tennis courts. This flexibility regarding ground conditions reduces civil engineering and waste disposal costs. (Site testing required separately)
In addition, the aluminum frames that we recommend not only enhance work efficiency but are also lightweight and durable.
By using a backhoe (available at nearly any construction site), the work is simple even on sloping or uneven terrain difficult to access with truck-type pilers.
Piles can also be installed on inclined ground (up to 15° slope angle) if the backhoe’s range of movement permits. This is the engineering method of the future for mega-solar projects.
