General layout of Daxigou Pipeline Water Diversion Project in Urumqi is introduced, and engineering characteristics with large in total head, high in single pressure, difficult in pressure partition, long in diversion distance, low in winter temperatures, large in total upper-stream sand are presented in the paper, the K9 cast-iron pressure pipe with working pressure of 2.5MPa combined with PCCP pipe are adapted to solve design keypoint of long diversion distance, 4 stage pressure partition is selected to reduce single stage pressure, water hammer pressure comprehensive protective measures and submerged sleeve valve are designed for the safety of engineering. It is indicated that solution methods are helpful for safety and liability in engineering.
