平度污水处理厂多单体天然地基换填施工技术OA

In the construction of multi-unit wastewater treatment plants,situations often arise where the excavated natural foundation does not reach the designed bearing stratum due to localized geological variations,necessitating ground improvement via the replacement method.Aiming for systematic construction control,this study establishes a complete technical system focusing on the core aspects of the replacement process,including precise trench excavation,subgrade treatment,layered spreading and compaction,and full-process quality inspection.Through the implementation of strict material control and layered compaction process management,combined with validation via field static load tests,the effective achievement of foundation bearing capacity is ensured.The research results form a standardized replacement construction method suitable for multi-unit structures with irregular foundations,providing a replicable technical pathway and practical reference for ground treatment in similar complex projects.
