Research on the ability to pump sediment through pipe

Soda residue is the industrial waste materials occurring during producing the pure alkali by ammonia soda process, it also can be used in the reclamation project after the research on its engineering characteristics. In the construction, the soda residue is pumped through a pipe and then is disposed by vacuum preloading method and so on. During pumping the soda residue, the pumping pressure, the pipe resistance and the diameter of the pipe are all relevant to the transportation distance. Based on the theories in hydromechanics, the law of transporting soda residue in the pipe is deduced, the formula for calculating the rule is applied and the algorithm for solving this formula is proposed. Viscosity and initial shear strength are determined by rotating viscometer; average flow velocity is measured by designed experimental appliance, and is proved to be in concordance to the field test result.
