Hubei Irrigation District Reconstruction Project, PE Water Pipeline Adaptation to Farmland Water Conservancy Supporting Construction

As a major agricultural province, Hubei's irrigation areas are the core carriers to ensure stable grain production and increase production. In recent years, irrigation area renovation projects are gradually upgrading the farmland water conservancy supporting system, among which PE water pipelines have become one of the core building materials with excellent adaptability. Hubei terrain covers plains, hills and hills, irrigation areas are widely distributed and the terrain is complex. The flexibility of PE water pipelines is just right to adapt to a variety of terrains, and the laying can be completed without too much modification of the landform, which greatly reduces the difficulty and cost of construction. At the same time, farmland irrigation water often contains acid and alkali components, and the corrosion resistance of PE pipelines is better than that of traditional pipes. It can serve stably for a long time and reduce the frequency of later maintenance. At the level of supporting construction, PE pipelines can be flexibly connected to field canals, irrigation gate valves and other equipment to achieve accurate connection of water transmission networks For the contiguous farmland in Jianghan Plain, large-diameter PE pipes can ensure large-flow water transportation and meet large-scale irrigation needs; for scattered fields in northern Hubei, small-diameter PE pipes can be selected to achieve point-to-point accurate water supply and avoid water waste. In some irrigation area renovation projects in Hubei, after the PE water pipeline replaced the old cement and cast iron pipes, the leakage rate was reduced to less than 5%, and the irrigation efficiency was increased by more than 30%, which not only saved water resources, but also reduced the irrigation cost of farmers. In addition, the PE pipeline has a short construction period, can be put into use quickly, does not delay agricultural time, and adapts to the seasonal needs of farmland water conservancy construction. In the future, with the continuous advancement of the transformation of irrigation areas in Hubei, PE water pipelines will play a greater role in the construction of farmland water conservancy facilities, helping to build an efficient and stable agricultural irrigation system and providing solid support for the development of agricultural modernization in Hubei.
