深基坑土钉与止水帷幕复合支护技术

Technology of Composite Supporting Methods of Soil Nails and Cement-soil Waterproof Wall for Deep Excavation

在施工实践基础上 ,归纳土钉与止水帷幕复合支护的施工步骤及在施工过程中应注意的事项 ,为施工单位提供系统的施作方法。实践证明 :在高地下水位的软弱土层中进行基坑支护时 。

Construction procedures and matters needing attention in construction of composite supporting methods of soil nails and cement soil waterproof wall are introduced for providing systematic implementary method to the construction unit The construction course and action principles of soil cement piles were expounded because the soil cement pile is one of the key components of composite soil nailing The practices of project show that the composite supporting methods of soil nails and cement soil waterproof wall is better supporting form than another when the excavation is located in the soft ground with the high water table
