Background Art

[0002] There are many challenges in traditional construction methods when constructing pile foundations on water. Site surveys before construction are often not comprehensive and detailed enough, making it difficult to accurately assess water and geological conditions, which may lead to many uncertainties during the construction process. The transportation of prefabricated piles also lacks reasonable planning, which can easily lead to damage to the pile body and low transportation efficiency, increasing construction costs and risks. In addition, the pile foundation positioning system is not accurate enough, affecting the quality and progress of construction; the pile driving process is not strictly controlled, which may cause damage to the pile body and construction safety hazards; the pile foundation detection methods are also limited and imperfect, making it difficult to accurately assess the performance of the pile foundation. These problems combined lead to low construction efficiency, difficulty in ensuring quality, increased costs, reduced safety, and inability to adapt to complex construction environments, limiting the optimal allocation of resources and the reliability of the project, and also hindering the development of water pile foundation construction technology.
