Ecological channel for agricultural irrigation and application of ecological channel

Abstract

The invention belongs to the technical field of agricultural irrigation engineering, provides an ecological channel for agricultural irrigation, and particularly relates to a U-shaped channel. The ecological channel comprises a channel body (1) and an ecological slope (2) of a certain length, wherein the ecological slope (2) is arranged in the longitudinal direction of the side of the channel and has a bigger slope coefficient m; the ecological slope (2) extends to one side or two sides according to available space of two sides of the channel; the ecological slope (2) in extending distribution is integrally connected with the channel body (1); the top of the ecological slope (2) is flush with the channel top. The invention further discloses an application of the ecological channel. The ecological slope (2) does not affect normal irrigation and water delivery functions on the side of the channel and can realize the ecological function. Particularly, when the temperature is high in summer and water recedes at the end of each irrigation, the ecological slope is not only the best escape place of animals such as snakes, frogs and the like, but also provides convenience for workers to enter the channel to clean sundries, so that manpower and material resources for large-scale dredging are saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water conservancy engineering, and relates to an ecological channel for agricultural irrigation and its application, in particular to a U-shaped channel, which is mainly applicable to plain areas. Background technique [0002] Traditional U-shaped irrigation channels generally adopt the "three-sided light" lining technology, which often only considers water saving and water delivery efficiency and ignores ecological functions. Generally, there are the following problems: 1. The traditional U-shaped channel is a hardened channel with a long length. Especially in summer, when the temperature is high, after each irrigation is completed and the channel recedes, the bottom of the channel dries up quickly, which makes snakes that stray into the channel 2. The slopes on both sides of the irrigation channel are steep, the channel is deep, and the lining is relatively smooth, which prevents snakes, fr...

Problems solved by technology

Generally, there are the following problems: 1. The traditional U-shaped channel is a hardened channel with a long length. Especially in summer, when the temperature is high, after each irrigation is completed and the channel recedes, the bottom of the channel dries up quickly, which makes snakes that stray into the channel 2. The slopes on both sides of the irrigation channel are steep, the channel is deep, and the lining is relatively smooth, which prevents snakes, frogs and other animals in the channel from escaping in time; 3. Traditional channels often bring water For some sediment, due to the deep channel and steep slope, personnel cannot enter the channel for dredging at any time, resulting in a large workload of channel dredging in plain areas
