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 ditch make the soil ditch have a certain anti-scouring ability, but the water flow in the ditch increases during the wet season, and the erosion of the ditch wall and bottom increases. According to the characteristics of precipitation, topography, and soil quality in this area, design an ecological ditch with a trapezoidal cross-section and fill holes 11 as rectangular holes. Prefabricate the ditch unit section 1 with concrete, and the upper frame 15 of the ditch unit section 1 is the width of the frame between every two filling holes 11. It is 0.08 meters, and the thickness is 0.06 meters. 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 rectangular hole is 0.2 meters, and the length of the rectangular hole is 0.8 meters. The outer wall of the ditch unit section 1 is provided with anchors 3 at the nodes of the frame, and the anchors 3 are reinforced concrete cones ...

Embodiment 2

[0032] The ditch is located in a hilly area, and the indigenous plants in the original soil ditch made the soil ditch have a certain anti-scouring capacity, but the flow of the ditch increased during the wet season, and the erosion of the ditch wall and bottom increased. According to the characteristics of precipitation, topography, and soil quality in this area, an ecological ditch with trapezoidal cross-section and filling hole 11 is designed as a triangular hole. 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 joints, and the anchor nails are reinforced concrete cones with a depth of 0.2 meters.

[0033] The filling hole 11 of the lower frame 16 of the ditch unit section 1 is filled with triangular bricks, and the pebbles or crushed stones with a diameter of 2 to 3 cm are filled between the frames 13 at the bottom of the ditch.

Embodiment 3

[0040]The ditch is located in the plain area and close to the village. The water flow in the original soil ditch is relatively slow, and the indigenous plants in it make the ditch have a certain anti-scouring capacity. According to the characteristics of precipitation, topography, and soil quality in this area, an ecological ditch with trapezoidal cross-section and rectangular holes is designed, and the ditch unit section 1 is prefabricated with concrete. 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 width of the frame between every two filled holes in the lower frame of the ditch unit section is 0.06m, the thickness is 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 anchors 3 at the nodes of the frame, and the anchors 3 are reinforced concrete cones with a depth of 0.2 meters.

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 in particular 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. 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 a...
