Problems solved by technology

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 amount of construction work, consumes a lot of materials, has a large impact on the environment of the construction site, is greatly affected by the weather, and lacks universal usability and sustainability. Issues such as usability need to be further improved

Embodiment 1

[0023] The original plants in the natural ditches make the soil ditches have a certain anti-scouring ability, but the water flow in the ditches increases during the wet season, and the erosion to the walls and bottom of the ditches increases. In view of the characteristics of precipitation, topography and soil quality in this area, an ecological ditch with trapezoidal cross section and filled holes 11 as rectangular holes is designed, and the ditch unit section 1 is prefabricated with concrete. The upper frame 15 of the ditch unit section 1 is filled with the width of the frame between the holes 11 every two The width of the rectangular hole is 0.3 meters, and the length of the rectangular hole is 0.8 meters. The width of the frame between every two filling holes 11 of the lower frame 16 of the trench unit section 1 is 0.06 meters, and the thickness is 0.06 meters. The width of the rectangular hole is 0.2 meters, and the length of the rectangular hole is 0.8 meters. The outer w...

Embodiment 2

[0032] The ditch is located in a hilly area. The indigenous plants in the original soil ditch make the soil ditch have a certain resistance to erosion, but the amount of water passing through the ditch increases during the wet season, and the erosion to the wall and bottom of the ditch increases. In view of the characteristics of precipitation, topography and soil quality in this area, an ecological ditch with trapezoidal cross section and filled holes 11 as triangular holes is designed. The ditch unit section 1 is prefabricated with concrete and the thickness is 0.06 meters. The outer wall of the ditch unit section 1 is in the frame Anchor nails are arranged at the nodes, which are reinforced concrete cones with a depth of 0.2 meters.

[0033] Triangular bricks are filled in the filling holes 11 of the lower frame 16 of the ditch unit section 1, and pebbles or gravel with a diameter of 2 to 3 cm are filled in the bottom frame 13 of the ditch.

Embodiment 3

[0040] The ditch is located in the plain area and close to the village. The original soil ditch has slow water flow, and the indigenous plants in it make the soil ditch have a certain resistance to erosion. According to the characteristics of precipitation, topography and soil quality in this area, the trapezoidal cross-section and the filling hole are rectangular hole ecological ditch designed. The ditch unit section 1 is prefabricated with concrete. The upper frame of the ditch unit section 1 has a width of 0.08 meters between two filling holes. The thickness is 0.06m, the width of the rectangular hole is 0.3m, and the length of the rectangular hole is 1.0m; the lower frame of the ditch unit section has a width of 0.06m and a thickness of 0.06m, and the width of the rectangular hole is 0.2m. , The length of the rectangular hole is 1 meter. The outer wall of the ditch unit section 1 is provided with anchor nails 3 at the nodes of the frame. The anchor nails 3 are reinforced co...

Abstract

The invention discloses a trapezoid ecological frame ditch which comprises a plurality of ditch unit segments with trapezoid cross sections, wherein the ditch unit segments are butted and laid in sequence to form a water diversion ditch; and each ditch unit segment adopts a frame structure with dense filling holes which are all filled with filling material. With a frame structure, the trapezoid ecological frame ditch can reduce the scour of running water to the side wall and the bottom of the ditch, and solves the problem that the exchange of matter energies in the ecological environment of a traditional ditch is blocked due to the sealing of the traditional ditch; and the frame structure of the trapezoid ecological frame ditch is convenient for construction, can shorten the construction period, reduces the construction amount, consumes a small amount of material, is stable and resistant to scouring, can increase the biomass of the wetland ecosystem of the ditch, realizes blockage, degradation, absorption and utilization of water pollutants, reduces and removes pollutants in water, and has better ecological functions.

Description

Technical field [0001] The invention is used in the field of ditch water and soil conservation and non-point source pollution control, and particularly relates to a trapezoidal 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. At the same time, with the development of social economy, the society's awareness of protecting the ecological environment has increased, and it has gradually become aware that farmland water pollution has become increasingly Serious environmental problems, and constructing 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 the research on the design ...
