Problems solved by technology

However, the existing irrigation and drainage ditches not only need to be partly dismantled and rebuilt, but also occupy more arable land, and the location of the escape design cannot be well determined, and are rarely used in existing farmland irrigation and drainage ditches In the design, it is still unable to solve the problem that field creatures stray into the ditch and cannot escape

Embodiment 1

[0037] In irrigation and drainage ditches with a vertical depth of 0.6 meters, bio-escape facilities are arranged in every 100-meter ditches where field organisms such as earthworms, frogs and water snakes stray into the ditches more often. For the distance from the top to the farmland and the slope ratio, three escape channels 2 with an inner diameter of 0.075 meters and lengths of 1 meter, 0.3 meters and 0.3 meters were intercepted to form the ditch section, connecting section and farmland section of the biological escape facility respectively. Before the escape channel 2 and the L-shaped pipe joint are connected, wrap them with water tape (leakage-proof tape) to prevent the escape channel 2 and the L-shaped pipe joint from being separated from each other or leaking due to water pressure. There are two fixed circular holes with a diameter of about 5 mm at the entrance and exit of the escape channel 2 in the ditch section. The escape channel 2 is tied with a rope, and the othe...

Embodiment 2

[0039]In irrigation and drainage ditches with a vertical depth of 1 meter, bio-escape facilities are arranged in every 80-meter ditches where field organisms, such as earthworms, frogs and water snakes, stray into the ditch. For the distance from the top to the farmland and the slope ratio, three escape channels 2 with an inner diameter of 0.15 meters and lengths of 1.5 meters, 0.6 meters and 0.5 meters are intercepted to form the ditch section, connecting section and farmland section of the biological escape facility respectively. Before the escape channel 2 and the L-shaped pipe joint are connected, wrap them with water tape (leak-proof tape) to prevent the escape channel 2 and the L-shaped pipe joint from being detached or leaking under water pressure. There are two fixed circular holes with a diameter of about 5 mm at the escape entrance and exit of the ditch section. The escape passage 2 is tied with a rope, and the other end is tied with heavy stones. The length of the ro...

Embodiment 3

[0041] In irrigation and drainage ditches with a vertical depth of 1.5 meters, bio-escape facilities are arranged in every 50-meter ditches where field organisms, such as earthworms, frogs and water snakes, stray into the ditch. For the distance from the top to the farmland and the slope ratio, three escape channels 2 with an inner diameter of 0.20 meters and lengths of 2 meters, 0.6 meters and 0.5 meters are intercepted to form the ditch section, connecting section and farmland section of the biological escape facility respectively. Before the escape channel 2 and the L-shaped pipe joint are connected, wrap them with water tape (leak-proof tape) to prevent the escape channel 2 and the L-shaped pipe joint from being detached or leaking under water pressure. There are two fixed circular holes with a diameter of about 10 mm at the entrance and exit of the escape channel 2 in the ditch section. The escape channel 2 is tied with a rope, and the other end is tied with a heavy stone....

Abstract

The invention discloses an organism escaping device for the trench of a farmland, which comprises an escaping channel placed in a draining-irrigating trench, wherein one end of the escaping channel is provided with a float, and the other end of the escaping channel is provided with a turning channel for being placed on the wall of the trench. According to the organism escaping device for the trench of the farmland, the arranged escaping channel is placed in the draining-irrigating trench, the turning channel is placed on the wall of the trench, and due to the arrangement of the float, an opening of the escaping channel is suspended on the water surface always, the organisms in the farmland can favorably climb to the escaping channel and climb to the wall of the trench along the escaping channel, such that the organisms can enter and exit from the field freely, the death quantity of the organisms entering the trench with ''three smooth surfaces'' by mistake is reduced, and the environment and ecology balance of the farmland is kept. Meanwhile, the escaping device can be mounted in any position of the existing trench, and the existing trench is fully used. The manufacturing cost is low, the mounting is convenient, repeated use is realized, and the present invention is suitable for the field of agricultural irrigation.

Description

technical field [0001] The invention relates to the field of agricultural irrigation and drainage, in particular to a biological escape device for farmland ditches. Background technique [0002] Modern agricultural irrigation and drainage ditches usually adopt the construction technology of cement slurry with stone masonry and brick masonry to reduce water leakage, speed up irrigation and drainage flow, increase the effective use of water, and increase the area of ​​farmland irrigation. Compared with traditional soil ditches, they are more durable and convenient. It is widely used in the design of farmland irrigation and drainage ditches. The cross-section of farmland irrigation and drainage ditches is generally a rectangle with the canal wall and canal bottom perpendicular, or a trapezoid with a slope ratio of 4:1 to 5:1 between the canal wall and the canal bottom; the distance between the upper and lower bottoms is 60 to 120 cm, The distance is 40-80 cm; both the canal wa...
