Section design method and device for irrigation and drainage dual-purpose channel, and equipment

Abstract

The invention provides a section design method and device for an irrigation and drainage dual-purpose channel, and equipment. The section design method for the irrigation and drainage dual-purpose channel comprises the following steps that: S10: calculating the drainage ability of the channel so as to judge whether the drainage requirements of the irrigation and drainage dual-purpose channel are met or not; S20: when the channel can not meet the drainage requirements of the irrigation and drainage dual-purpose channel, regulating the channel bottom elevation and the design water level of the channel to enable the channel to meet the drainage requirements of the irrigation and drainage dual-purpose channel; and S30: on the basis of the regulated channel bottom elevation, designing the section dimension of the irrigation and drainage dual-purpose channel to enable the flow and the water level of the channel to meet the irrigation requirements. According to the section design method, which is disclosed by the embodiment of the invention, for the irrigation and drainage dual-purpose channel, the existing channel is transformed into the irrigation and drainage dual-purpose channel, andthe section of the irrigation and drainage dual-purpose channel is designed in a transformation process so as to guarantee the irrigation requirements of an irrigation area to a maximum degree in a most economical way.

Description

Technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a method, device, equipment and computer-readable storage medium for designing a cross-section of a dual-purpose irrigation and drainage channel. Background technique [0002] In some areas where paddy fields are developing rapidly, groundwater irrigation is the main source of water, and this kind of irrigation water security is low. Therefore, it is necessary to develop large and medium-sized irrigation areas with surface water sources as the main source. However, according to the previous canal arrangement principles, most of the new backbone irrigation channels occupy a large area and are difficult to implement. Moreover, new irrigation channels are not conducive to cost saving. Summary of the invention [0003] In view of this, the present invention provides a method, device, equipment and computer-readable storage medium for designing a cross-section of a dua...

AI Technical Summary

Problems solved by technology

[0002] In some areas where paddy fields are developing rapidly, the water source is mainly groundwater irrigation, which has a low degree of water security for irrigation.

Therefore, it is necessary to develop large and medium-sized irrigation areas mainly based on surface water sources. However, according to the previous layout principles of canal systems, most of the new backbone irrigation channels occupy a large area and are difficult to implement. Moreover, new irrigation channels are not conducive to saving costs.
