Scope

Scope: This standard is formulated to regulate the application of long-spiral-inserted composite piles, ensuring their safe and practical use, advanced technology, economic rationality, reliable quality, and environmental friendliness in design, construction, inspection, and acceptance. This standard applies to the design, construction, inspection, and acceptance of long-spiral-inserted composite piles used in building and municipal engineering projects. When selecting the design and construction parameters for long-spiral-inserted composite piles, comprehensive analysis of factors such as engineering geology and hydrogeology conditions, superstructure types, functional requirements, load characteristics, construction conditions, environmental and regional experience, etc. should be conducted, and quality control and management should be strengthened during the construction process. In addition to this standard, the design, construction, and acceptance of long-spiral-inserted composite piles shall also comply with the provisions of relevant national and local standards and codes. Main technical contents: Long-spiral-inserted composite piles are suitable for foundations such as bare fill, silt, silt-clay soil, clay, silty soil, sandy soil, gravel soil, residual soil, strongly weathered soil, and interbedded layers of clay and silty soil formed by the Yellow River sedimentation. Before the design and construction of long-spiral-inserted composite piles, geotechnical engineering investigations shall be conducted in accordance with current national standards to identify the types and engineering properties of each soil layer, groundwater conditions, and corrosivity. The design of long-spiral-inserted composite piles shall meet the requirements of bearing capacity, deformation, and stability, and shall comply with the following provisions: 1. The structural configuration and parameters of the composite pile shafts shall be selected based on geological conditions, str
