Application of increased safety guard board slice technology in dyke fortification through silt-engining project

摘要

This paper mainly stuthes 6PNL slurry-pump guard board (SPGB) which is the main mechanism of the Starry intake and dyke fortification project .6PNL SPGB can bar slurry and it touches high-speed and high-sedunent-concentration slurry directly .So it abrades and cavitates very quickly .which affects the construction and increases the project cost .In order to reduce the project cost ,We investigate and research and finally feel about tbe conclusion :when SPGB abrades and wastes ,we can increase a guard board and reuse the waste to reduce the project cost.
