Abstract: |
The main purpose of drainage engineering in irrigated areas is to remove excess water from the ground, lower the groundwater level and regulate soil moisture, so as to achieve stable agricultural yield, high yield and soil improvement. Its task is to create a good soil and water environment for the normal growth of crops.The design of drainage channel in irrigation area directly affects the benefit and success of drainage project.The design of main drainage channel should determine the drainage standard, drainage scope and drainage requirements of farmland, and plan the drainage zoning and drainage mode. The key is to do a good demonstration of scale, then choose the drainage outlet and drainage area, and then conduct the design of vertical and horizontal sections of channels and buildings.In view of the fact that there are not many and detailed articles on this subject, this paper, taking the design of a drainage trunk canal in xinjiang as an example, describes the ideas and methods for the demonstration of drainage trunk canal project scale, so as to provide direct reference and application for professional and technical personnel. |
