Spiral Pile

It is mainly composed of spiral blades, steel shafts and flanges. The spiral blades are the core part and are welded onto the steel shafts. Their quantity, diameter and spacing are designed according to engineering requirements. The steel shafts are made of high-strength steel and undergo hot-dip galvanizing treatment to enhance corrosion resistance. The flanges are located at the top and are used to connect the load-bearing structure.

Full life cycle management of photovoltaic spiral piles: technical paths and practices from design to recycling

Full life cycle management of photovoltaic spiral piles: technical paths and practices from design to recycling

The value of photovoltaic spiral ground piles lies not only in their initial advantage of "easy installation," but also requires scientific management throughout their entire life cycle (design - construction - operation and maintenance - recycling) to achieve the goals of "long-term reliability, optimal cost, and eco-friendliness." Especially in extreme geological scenarios such as frozen soil and soft soil, full-lifecycle management directly determines the pile's bearing stability and project return on investment. This article focuses on key aspects of the spiral ground pile life cycle, analyzing technical optimization strategies and practical cases to fill the gap in extreme geological adaptation and recycling.

Selection and optimization strategies of photovoltaic brackets in different climate zones

Selection and optimization strategies of photovoltaic brackets in different climate zones

During the implementation of photovoltaic power generation projects, climatic conditions are key factors affecting the performance and lifespan of photovoltaic mounting systems. High temperatures and high humidity can easily lead to mounting corrosion, severe cold and snow can test the mounting's load-bearing capacity, and strong winds and sandstorms can cause mounting wear and structural deformation. This article analyzes the core challenges facing photovoltaic mounting systems in four typical climate zones and proposes appropriate selection solutions and optimization strategies to help improve the stability and cost-effectiveness of photovoltaic systems in complex climates.

Photovoltaic spiral piles: efficient adaptation and technical practice of photovoltaic support foundation

In photovoltaic project foundation engineering, spiral ground piles, with their advantages of "no excavation required, quick installation, and strong load-bearing capacity," have become a key alternative to traditional concrete foundations. They are particularly well-suited for photovoltaic applications in complex terrain and ecologically sensitive environments. As the "underground support" for photovoltaic racks, their performance directly impacts rack stability and the project's lifecycle cost. This article focuses on the core characteristics of spiral ground piles, detailing their performance indicators, material selection, scenario adaptation solutions, and key construction quality control points, providing a practical guide for photovoltaic project foundation design.

Cost control and multi-scenario adaptation design practice of photovoltaic brackets

In the context of grid parity for photovoltaic power generation, cost reduction, efficiency improvement, and scenario-specific adaptation of photovoltaic brackets are key to project profitability. While ensuring structural safety, they must reduce overall lifecycle costs (materials, construction, and operation and maintenance) while also adapting to the specific needs of diverse scenarios such as "photovoltaic + agriculture," "photovoltaic + sand control," and "rooftop photovoltaics." This article examines bracket design optimization strategies based on the core dimensions of cost control, combining six typical application scenarios to provide practical technical solutions for photovoltaic projects.
