Abstract: Challenges in the cementgravel mixing soils are the controlling of cement during the construction, ununiformed mixing results and low mixing efficiency. This paper presents measures that can improve the construction quality of this technology. Case history of Chashan Lock Project in Linyi indicates that better mixing quality; degrees of compaction for the mix soils and the construction efficiency could be achieved while the cost of installation could also be reduced. \=
