North Water Diversion Project water conveyance channel lining , long routes , the concrete square a large amount of the engineering quality of the concrete on the south-to-north water diversion project , safety and durability is essential , therefore , research is necessary to solve the channel slope concrete structure vibration compacting properties Experimental study on the impact of various factors , the construction of the South channel lining has a guiding role . Through site visits , the domestic research , relevant literature , information , conscientiously sum up the advanced experience on the basis of the actual situation closely integrated engineering , engineering actual use of raw materials , physical and mechanical properties of the concrete , the flow variable performance and vibration viscosity theory test research ; trial research the slope concrete slump testing, using bubbles float test concrete vibration viscosity coefficient ; simulated construction site and construction of the ramp concrete vibration compacting effect . Impact of various elements affect the concrete structure vibration compacting best range through the analysis of the test results obtained , optimizing the parameters of dense , mechanized lining concrete vibrated dense , surface roughness and the strength of concrete entities meet the design requirements , to obtain concrete density , for the realization of the the large channels mechanized lining favorable technical support .
