Hydraulic reclamation construction involves theoretical knowledge of hydraulic pipeline transport，including that of the combined system composed of pumps，mud pumps，and pipelines，and the subsystems are interrelated and relatively complex. Consequently，the dredging management personnel find it difficult to obtain a proper understanding and analyze problems encountered in the process of hydraulic transport inaccurately. Regarding the above problems，this paper adopts energy conservation analysis to analyze the principle of hydraulic pipeline transport，derive empirical formulas，and analyze examples. Dredging management personnel can thereby deepen their understanding of the principle and formulas，predict the production capacity of hydraulic reclamation more accurately，analyze and solve technical problems in construction，achieve fine management，and avoid relevant risks.
