The design for the large-scale water transmission pipeline running across the creeks is involved.

The large-scale water delivery channel usually passes through a mass of transferring structures,how to reasonably determine the head loss of these structures is a key question in the simulation of channel operation dispatching.

On project practice for direct weighting in long-distance water pipeline

With comparison of properties and advantages and disadvantages of different inside and outside anti-corrosion methods and materials, the selection of anti-corrosion of buried steel water pipeline are discussed.

This paper makes systematic analysis on the geneses and harmfulness of pipe scale in urban water pipeline,and advances some measures for preventing the scale in urban water pipeline.

The analytical calculation of crack accident of water transmission pipe from Fengjiashan Reservoir was performed in terms of the design check,water-hammer control analysis,construction,supervision,pipe material quality and so on.

It is believed that the longdistance water conveyance pipeline is suitable for using 19Mn steel with higher strength, and fewer boosing stages and higher pressure should be adopted for water conveyance.
