水利水电工程施工作业土壤常为湿淤性粘土、水下土壤和河卵砾石,由于其特殊性质,加之依不同的作业用途,对施工机械的挖掘装置往往有特别的要求,为通用工程机械挖掘装置所不能包容。本文主要研究湿淤粘土和河卵砾石挖掘阻力特性及所需单斗挖掘装置的结构和设计特点。 Water conservancy and hydropower project construction work soil is often wet sludge, underwater soil and river gravel, due to its special nature, coupled with different operating purposes, often have special requirements for excavation equipment of construction machinery, mining for general engineering machinery The device cannot contain it. This paper mainly studies the characteristics of excavation resistance of wet silting clay and river gravel, and the structure and design features of the required single bucket excavation device.
