Key Points of Channel Reconstruction Design of Phase I Project of Dagong Irrigation District
The implementing the transformation of large and medium-sized irrigation districts is constructed to improve irrigation and drainage engineering facilities,improve the efficiency of water transmission and distribution and the irrigation and drainage guarantee rate in irrigation areas,and improve agricultural production strips.The water loss caused by water leakage is serious.In order to reduce the water loss of the channel and improve the water efficiency in canal system,anti-seepage lining measures should be taken for the channel.Taking the channel design of the first phase of the continuous construction and modernization of Dagong Irrigation District in the"14th Five-Year Plan"of Henan Province as an example,the channel longitudinal section,cross-section,structural design characteristics,key points and technical analysis are elaborated to provide a reference for optimizing the design level of channel transformation.
