| Abstract: | According to a workshop indoor ground slab settlement in Ningbo, based on the analysis on the settlement reasons and trend, the comparison is made on several reinforcement methods by considering the special conditions of this project, anchor pile beam-slab structure is determined to be adopted to deal with the indoor ground slab settlement. A multifunctional small static pile driver is developed, multi-stage extrusion and expansion thorough backfill method is used with small ground surface damage to solve the construction difficulties and realize the smooth construction of special engineering project in complex environment conditions. This project treatment has achieved good effects. |
