Scope

Scope: This standard is formulated to regulate the application technology of cement-soil slurry for backfilling, ensuring its safety, applicability, advanced technology, economic rationality, and environmental protection. This standard applies to the design, construction, quality inspection, and acceptance of backfilling for foundation pits in construction and municipal engineering projects. The design and construction of cement-soil slurry for backfilling shall comply with the principles of local adaptation, resource conservation, and green construction. The design, construction, and performance testing methods of cement-soil slurry for backfilling shall, in addition to complying with this standard, also comply with relevant national standards currently in force. Main technical contents: Cement-soil slurry can be used for backfilling in construction and municipal foundation pits. Before the design and construction of cement-soil slurry, an indoor mix proportion test shall be conducted. Based on the design requirements, the type of soil material, and construction conditions, the composition scheme and corresponding mix proportion of cement-soil slurry shall be optimized. The cement and soil materials used in the indoor mix proportion test shall be consistent with those used in on-site construction. A special design shall be conducted for the backfilling project of cement-soil slurry. The performance indicators such as slump, spreadability, and strength of cement-soil slurry shall be determined through on-site batching according to the actual requirements of the project, and shall meet the requirements of construction processes such as pumping, tank truck transportation, and chute backfilling. A full-process quality control shall be implemented for the backfilling project of cement-soil slurry, and a special construction plan shall be formulated before the backfilling construction, with clear inspection contents and strengthened checks during the construction pro
