复杂地质条件下地下连续墙成槽施工技术

The trench construction technology of underground continuous wall under complex geological condition

以南京市洪武路污水提升泵站地下连续墙成槽工程为例,从泥浆制备、杂填土层至强风化泥岩层成槽、中风化泥岩层成槽三方面,阐述了复杂地质条件下连续墙成槽施工技术,并提出了预防地下连续墙成槽塌方的措施,确保了槽壁的稳定性。

Taking the underground continuous wall trench engineering of sewage pumping station in Nanjing Hongwu Road as an example, from the slurry preparation, miscellaneous fill soil to strong weathering mud-stone layer trench, weathered mudtone layer trench three aspects, elaboated the continuous wall trench construction technology under complex geological conditions, and put forward the measures prevention of under-ground continuous wall trench collapse, ensured the stability of slot wall.
