[0002] Steel casings, as a commonly used construction component, play a crucial role in foundation engineering. However, with increasingly complex geological conditions and ever-expanding project scale, higher demands are placed on the sinking and positioning technology of steel casings. Especially in situations with complex geological conditions, uneven soil layer distribution, or the presence of weak soil layers, double-layer positioning guide frames, compared to single-layer guide devices, improve the stability and positioning accuracy of steel casings during sinking by adding a guiding layer, and have therefore gained widespread application. However, with the continuous increase in the difficulty of engineering construction and quality requirements, traditional double-layer steel casing positioning frames suffer from problems such as poor construction accuracy, low adjustment efficiency, and weak construction load-bearing capacity and stability. Therefore, optimizing the double-layer guide positioning frame device for large-diameter steel casings to improve construction accuracy and efficiency and ensure construction quality is of significant practical importance.
