What are the problems of using hot-dip galvanized spiral ground pile in marshland? How to solve them?

The problems of using hot-dip galvanized spiral ground pile in marshland may include:

Limitation of stress direction: The stress characteristics of spiral ground pile dictate that it can only act in a direction perpendicular to the ground, and it has relatively little resistance in the horizontal direction. Therefore, in natural disasters such as earthquakes or extreme weather conditions such as strong winds, spiral ground piles may not be able to provide sufficient support, resulting in building collapse or tilt.
Limitation of applicable sites: The use of spiral ground piles is somewhat limited by the type of land. For example, marshland and soft ground conditions can limit the effectiveness of spiral ground piles, thus limiting their widespread application.
Difficult installation: The installation of spiral ground piles requires professional equipment and technical personnel. If the installation process is not technically sound or the equipment is not appropriate, it can have serious consequences. In some situations, such as building in low-lying areas, the spiral ground pile needs to be drilled into the soil at a deeper depth, which increases installation difficulty and cost.
To solve these problems, we can consider the following:

Selecting appropriate spiral ground piles: For soft ground such as marshland, it is recommended to use spiral ground piles specifically designed for soft soil to enhance their horizontal stress resistance.
Increasing pile depth: For building in low-lying areas, we can increase the depth of the spiral ground pile to enhance its support strength.
Proper preparation before installation: Before installation, it is necessary to conduct geological investigation to understand the geological conditions in order to select the appropriate installation method and location. At the same time, it is also necessary to ensure that the equipment and personnel used during installation have appropriate qualifications and technical level.
Considering other reinforcement methods: For some particularly important buildings or areas with frequent extreme weather conditions such as earthquakes and strong winds, other reinforcement methods can be considered to enhance building stability, such as underground continuous walls, soil mixing columns, etc.

In general, the use of hot-dip galvanized spiral ground pile in marshland requires full consideration of its stress characteristics, applicable sites, and installation difficulties, and corresponding measures should be taken to address these issues.
