Example Embodiment

[0024] Example 1:

[0025] The present invention designs a U-shaped frame ecological ditch according to regional farmland irrigation conditions. The U-shaped frame ditch includes a ditch unit section 1 and a filler. The ditch unit section 1 is a prefabricated concrete structure, and the filling hole 11 is rectangular, and the side The wall filling hole 11 is filled with rectangular bricks, and the canal bottom filling hole 11 is filled with pebbles that are widely used in the project area. The voids in the hollow bricks 2 and the voids between the pebbles are filled with farming soil, and watergrass and cress are planted on the farming soil.

[0026] The plants in the natural soil ditches in the project area make it have a certain resistance to erosion, but as the water flow in the ditches increases, the amount of sediment in the ditches that is washed by the flowing water increases. According to the characteristics of precipitation, topography and soil quality in this area, a U-sh...

[0029] Example 2:

[0030] The present invention designs a U-shaped frame ecological ditch according to the drainage and irrigation conditions of the ditch in the area. The U-shaped frame ditch includes a ditch unit section 1 and a filler. The ditch unit section 1 is a prefabricated concrete structure, and the filling hole 11 is filled with hollow bricks. 2. Fill the gaps of the hollow brick 2 with gravel or pebbles, then fill the farming soil, and plant emergent plants on the farming soil.

[0031] The plants in the natural soil drainage ditches in the project area make it have a certain resistance to erosion, but with the increase of rainfall in the rainy season, the erosion of the sediment in the drainage ditches by drainage increases, and a small area of ​​collapse occurred in some sections. According to the characteristics of precipitation, topography, and soil quality in this area, a U-shaped cross-section and a triangular filled hole 11 structural ecological ditch are design...

[0033] Example 3:

[0034] The present invention designs a U-shaped frame ecological ditch according to the drainage and irrigation conditions of the ditch in the area. The U-shaped frame ditch includes a ditch unit section 1 and a filler. The ditch unit section 1 is a prefabricated concrete structure, and the filling hole 11 is filled with hollow bricks. 2. Fill the gaps of the hollow brick 2 with gravel or pebbles, then fill the farming soil, and plant emergent plants on the farming soil.

[0035] The emergent plants in the natural drainage ditch play a certain role in soil and water conservation, but the downstream silt accumulation blocks the drainage ditch. According to the characteristics of precipitation, topography and soil quality in this area, the ecological ditch with U-shaped cross section and diamond-shaped filling hole 11 is designed. The ditch unit section 1 is prefabricated with concrete. The length of the ditch unit section 1 is 150cm, and the shape of the filling ...

Abstract

The invention discloses a U-shaped ecological frame channel, which comprises a plurality of channel unit sections of which the cross sections are in the shape of U; the channel unit sections are paved in sequence in a butt joint manner to form the channel; each channel unit section is of a frame structure densely covered with a plurality of filling holes; filler fills in each filling hole. As the structural style of the frame structure is adopted by the U-shaped ecological frame channel, not only can scouring generated to the side walls and the bottom of the channel by flowing water be reduced, and the problem that matter energy exchange in the ecological environment of the channel is hindered due to cementing of the traditional channel is solved; by adopting the frame structure style of the U-shaped ecological frame channel disclosed by the invention, construction is convenient, the building construction period can be shortened, the construction work amount is reduced, the material consumption is low, and the structure is stable and is capable of resisting scouring; moreover, the biomass of the wet-land ecological system of the channel can be improved, blocking, degradation, absorption and utilization on water contaminants are realized, and the contaminants in water are reduced and discharged; the U-shaped ecological frame channel has a better ecological function.

Description

technical field [0001] The invention is used in the field of ditch water and soil conservation and non-point source pollution control, and in particular relates to a U-shaped ecological frame ditch. Background technique [0002] In order to improve farmland cultivation conditions and ensure farmland irrigation and drainage, high-standard basic farmland construction projects are being implemented in the vast rural areas of our country. serious environmental problems, and building and maintaining a good ditch wetland ecosystem has become an important way to solve this problem. [0003] At present, the research on ecological ditches mainly focuses on the purification mechanism and the purification effect of planting plants, while there are relatively few studies on the design and construction of the ditches. Due to regional differences in agricultural non-point source pollution and human-land conflicts, the invented ecological ditch occupies a large area, requires a large amou...
