Optimum Process of Rock Drilling Hammer in Construction of Cemented Sand
There is a certain difference in engineering properties of cemented sand,shale and sandstone.If the grab dredgers equipped with rock drilling hammers are used to crush or remove debris,the layered detail is combined with the physical properties of cemented sand to modify the parameters of construction process,optimize equipment,and create appropriate conditions,which will improve the efficiency of rock drilling and ensure safe construction.Based on a a dredger-fill works of the reconstruction of Skikda oil-gas port in Algeria,some key points was described in detail,including the characteristics of cemented sand,rock drilling equipment,and the basic process of grab plus rock drilling rod.The optimum idea and tendency of rock-drilling process were analyzed from the aspects of the construction characteristics,the adjustment of equipment and rock drilling process by stages.
