Scope

Scope: 1.0.1 This standard is formulated to regulate the application of threaded cement-soil composite piles, ensuring their safe and appropriate use, technological advancement, economic rationality, quality assurance, and environmental protection. 1.0.2 This standard applies to the design, construction, quality inspection, and acceptance of threaded cement-soil composite piles. 1.0.3 The design and construction of threaded cement-soil composite piles should comprehensively analyze the site's engineering geology and hydrogeological conditions, the type of superstructure and foundation form, the intended use, load characteristics, construction and environmental conditions, and adhere to the principles of site-specific adaptation, resource conservation, and environmental protection, while strengthening project quality control and management. 1.0.4 In addition to complying with this standard, the design, construction, quality inspection, and acceptance of threaded cement-soil composite piles shall also comply with the provisions of relevant national standards currently in force. Main Technical Content: 3.0.1 Threaded cement-soil composite piles are suitable for general clay, silt, sand, gravel, and residual soil layers. 3.0.2 Before the design and construction of threaded cement-soil composite piles, a geotechnical investigation should be conducted in accordance with current national standards to identify the types and engineering properties of each soil layer, as well as groundwater conditions and corrosivity. 3.0.3 For sites with no similar project experience or complex geological conditions, pile-driving process tests and bearing capacity tests should be conducted in representative areas of the site. 3.0.4 For projects using threaded cement-soil composite piles, settlement observations should be conducted during construction and subsequent use, and comply with relevant regulations.
