Embodiment 1

[0019] Ecologically efficient irrigation canal facilities for paddy fields, including canals and auxiliary buildings. The cross-section of the channel 1 is U-shaped and hardened with U-shaped concrete slabs. The upper width and height of the channel are both 50 cm, and the bottom is 5 cm lower than the field surface. The ancillary buildings include irrigation tanks 2 , irrigation gates 5 , ecological panels 4 and control gates 3 . The irrigation tank is located on the side of the channel in the middle of each irrigation area, the bottom of the irrigation tank is the same height as the field surface, and its width is 30cm, height is 45cm, and length is 50cm; the irrigation gate is a wedge gate valve, It is set in the irrigation tank and close to the upper edge of the U-shaped concrete slab; the ecological slab is a 30cm×58cm×5cm concrete slab with several steps on one side, and the lengths of the three sides of the steps are 1cm×1.8cm×4.5cm, Among them, the long side is locate...

Embodiment 2

[0021] Ecologically efficient irrigation canal facilities for paddy fields, including canals and auxiliary buildings. The cross section of the channel 1 is U-shaped and hardened with U-shaped concrete slabs, and the bottom of the channel is slightly lower than the field surface. The ancillary buildings include irrigation tanks 2 , irrigation gates 5 , ecological panels 4 and control gates 3 . The irrigation trough is located on the side of the channel in the middle of each irrigation plot, the bottom and height of the irrigation trough are the same height as the field surface and the upper edge of the channel respectively, and have a moderate width and length that meet the irrigation requirements; the irrigation sluice It is a wedge-type gate valve, located in the irrigation tank and close to the upper edge of the U-shaped concrete slab; the ecological slab is a cuboid concrete slab with a moderately sized step for biological climbing, segmented and cross-leaning On the botto...

Abstract

An ecological and efficient facility for an irrigation channel of a rice field comprises a channel and an ancillary building, wherein the cross section of the channel adopts a U shape, and the bottom of the channel is lower than the field surface; the ancillary building comprises a water irrigation groove, a water irrigation gate, ecological boards and check gates; the water irrigation groove is located at the side edge of the channel in the middle of each irrigation cell, and the bottom of the water irrigation groove is as high as the field surface; the water irrigation gate is a wedge type flashboard gate valve, is located in the water irrigation tank and is tightly close to the upper edge of the channel; a corrugated board is arranged on one surface of each ecological board, the ecological boards are sectioned and lean against the bottom and the upper edge of the channel in an intersected manner, and the corrugated surfaces face upwards; and the check gates are wedge type flashboard gate valves and are sectioned and arranged in the channel. With the adoption of the ecological and efficient facility for the irrigation channel of the rice field, water resources can be efficiently utilized, irrigation efficiency, labor productivity and ecological benefits can be improved, the cultivated land can be saved, and the ecological and efficient facility is low in construction costs and maintenance cost, firm, durable and simple to operate and maintain, thereby facilitating large-area popularization and application.

Description

technical field [0001] The invention belongs to the technical field of farmland irrigation infrastructure, in particular to a rice field irrigation infrastructure technology integrating ecology and high efficiency. Background technique [0002] Farmland irrigation channels in my country can be divided into trapezoidal, rectangular, semicircular and U-shaped according to their cross-sectional geometry, and can be divided into soil, masonry and concrete according to their materials. Among them, trapezoidal channels are soil or concrete materials, and rectangular channels are For masonry or concrete materials, semicircular and U-shaped for concrete materials, trapezoidal and rectangular channels are the most widely used at present. In recent years, with the rapid development of social economy and the continuous improvement of land consolidation technology, as well as the gradual improvement of the understanding of the advantages of U-shaped channels, the application of U-shaped ...
