However, due to the characteristics of the smooth structure of the vertical surface of the side wall of the assembled rectangular canal, especially the canal with larger width, the passage of amphibian organisms and animals is cut, once animals represented by hares, snakes and frogs fall into the canal, the escape is difficult to climb out due to the smooth wall of the canal. As the irrigation channel generally adopts intermittent water supply, the amphibian or aquatic animals die due to water shortage in hot weather in summer once the water in the channel is evaporated. Over time, ecological balance is influenced, and therefore technical research on ecological components of the assembled rectangular channel is carried out, and the requirements of high-standard farmland assembled rectangular channel engineering construction and ecology are met.

Furthermore, the included angle between the escape channel plate and the horizontal plane is 15-20 degrees.

Furthermore, the escape channel plates are provided with two groups, namely a first group of escape channel plates and a second group of escape channel plates, each group of escape channel plates comprises two escape channel plates, the two escape channel plates are opposite in inclination and are connected end to end, a transition platform is arranged at the joint of the two escape channel plates, the first group of escape channel plates and the second group of escape channel plates are symmetrically arranged relative to a longitudinal central line, and the transition platform on the first group of escape channel plates and the transition platform on the second group of escape channel plates are arranged in a reverse direction.

The invention has the beneficial effects that:

according to the invention, the square holes are formed in the rectangular groove body, and the rectangular channel and the square holes are matched for use, so that the functions of distributing water and distributing water at any angle of various irrigation channels in the field are met.

And secondly, the ecological general member is arranged in the assembled rectangular channel, so that escape, migration and survival conditions are provided for escape of terrestrial animals, migration of amphibians and survival of aquatic animals which carelessly fall into the channel on the premise of ensuring safety of water supply and drainage in the field.

The assembly type rectangular channel and the ecological technology are brought into the assembly type concrete rectangular channel application technical specification of the local standard of Heilongjiang province, the invention provides technical support for solving the problems of water-saving irrigation and biological channel splitting of the assembly type concrete channel, perfects the ecological corridor, restores field biological communities and ecological chains and builds a healthy and stable rural ecological system.

Detailed Description

The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 3, and includes a rectangular tank 1 and two escape passage plates 2, a square hole 3 is provided on a side wall of the rectangular tank 1, the escape passage plates 2 are obliquely arranged in the rectangular tank 1, the oblique directions of the two escape passage plates 2 are opposite, and the upper surface of the escape passage plate 2 is stepped.

The second embodiment is as follows: the embodiment is described with reference to fig. 2, in which the included angle α between the escape passageway plate 2 and the horizontal plane is 15 to 20 °; other components and connections are the same as those in the first embodiment.

The third concrete implementation mode: the present embodiment is described with reference to fig. 4 to 6, in the present embodiment, two groups of escape channel plates 2 are provided, which are a first group of escape channel plates a and a second group of escape channel plates B, each group of escape channel plates includes two escape channel plates 2, the two escape channel plates 2 are opposite in inclination and connected end to end, a transition platform 4 is provided at a joint of the two escape channel plates 2, the first group of escape channel plates a and the second group of escape channel plates B are symmetrically arranged with respect to a longitudinal center line N-N, and the transition platform 4 on the first group of escape channel plates a and the transition platform 4 on the second group of escape channel plates B are arranged in an opposite direction. The two groups of escape channel plates ensure that the escape and migration directions of animals are random and multidirectional, prevent the biological community from being cleaved and are beneficial to ecological balance. The transition platform 4 enables the two escape channel plates 2 to be smoothly connected, and the escape and migration of the small animals are easier.
