[0024] The following is combined with Figure 1-4 This application is described in further detail.
[0025] Example 1:
[0026] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4The present application discloses a prefabricated ecological ditch, which includes an ecological ditch body 1, a prefabricated ditch wall 3, a prefabricated bottom plate 4, and water purification plants 6.
[0027] After trenching, the main body of the ecological ditch 1 is compacted with undisturbed soil to form the main body of the ecological ditch 1, which is used to lay the prefabricated channel wall 3 and prefabricated base 4. The ditch is excavated using an excavator's T-shaped bucket. After the trench is formed, the prefabricated channel wall 3 and prefabricated base 4 are laid, and finally, filler is laid and overplanted.
[0028] Two prefabricated channel walls 3 and prefabricated bottom plates 4 are spliced and fixed with cement to form an inverted trapezoidal ditch. The material of the prefabricated channel wall 3 and the prefabricated bottom plate 4 is set to concrete or PE material. A first partition 7 is set on the central axis of the prefabricated bottom plate 4 inside the ecological ditch, and a plurality of second partitions 8 are set in the vertical direction of the central axis. The first partition 7 and the second partition 8 are both perpendicular to the prefabricated bottom plate 4. The first partition 7 and the second partition 8 together form a single partition 9. The partition 9 includes a green plant trough and a water storage trough. The green plant trough and the water storage trough are distributed at intervals. The green plant trough is planted with water purification plants 6, and the water storage trough is used to store water. Figure 4 The water storage tank 9 is internally provided with a water storage plate 12, which can be configured as a sponge. The water storage plate 12 is used to store water. The water storage tank 9 has a protrusion on its inner wall. A first filter screen 2 is fixedly placed on the protrusion to filter debris such as fallen leaves from entering the tank 9, preventing blockage of the tank 9 or the perforated water distribution pipe 5. The first filter screen 2 also prevents water evaporation. The water storage tank is used to store water when the water content is sufficient. When the water content is insufficient, it provides water for the water purification plants 6 planted therein.
[0029] Multiple pipe inlet holes are provided at corresponding positions on a single second partition 8. Multiple perforated water distribution pipes 5 are provided through the pipe inlet holes. Multiple drainage holes are provided in the walls of these perforated water distribution pipes 5 to regulate water circulation. A second filter 13 can be provided within the perforated water distribution pipes 5 to provide a filter.
[0030] A prefabricated permeable partition 10 is provided on the first partition 7 and the second partition 8 perpendicular to the partition groove 9. The prefabricated permeable partition 10 is parallel to the prefabricated bottom plate 4. The prefabricated permeable partition 10 is located above multiple open-hole water distribution pipes 5. The layered structure makes the sewage water distribution effect better.
[0031] The greening trough, planted with water-purifying plants 6, has denitrification and phosphorus removal filler laid beneath the prefabricated permeable baffles 10. This improves wastewater treatment, effectively reducing nitrogen and phosphorus content in wastewater, thereby reducing the risk of eutrophication and protecting the aquatic environment. A sand and gravel mixed planting soil is laid above the prefabricated permeable baffles 10 for growing water-purifying plants 6.
[0032] The inner wall of the prefabricated channel wall 3 is provided with reserved holes 11 for planting aquatic plants, and the prefabricated bottom plate 4 has no holes.
[0033] The working principle of the embodiment of this application:
[0034] Construction process: Prefabricate channel walls and floor → Excavate trench → Lay channel walls and floor → Lay fill → Plant. The entire construction process is simple and easy to operate, ensuring better control of construction quality.
[0035] Water flows into the ecological ditch from one end, passes through multiple perforated water pipes 5, and flows out from the other end of the ecological ditch. Flowing vertically, even during non-rainy periods, a certain amount of water can still flow in the ditch.
[0036] The ecological ditch construction method of the present application is simple to implement, more efficient, and saves labor costs. The channel wall and bottom plate are prefabricated in advance, the quality assurance is more stringent and unified, and the prefabricated channel wall 3 is easier to replace and repair in the later stage. By setting the partition 9, some single partitions 9 are used to plant water purification plants 6, and some single partitions 9 are used to store water. The partition 9 cooperates with the perforated water distribution pipe 5 to store water and regulate water circulation. By setting the prefabricated permeable partition 10, the layered structure makes the sewage water distribution effect better; by introducing denitrification and phosphorus removal fillers, the sewage treatment effect is better, and the water purification plants 6 and ecological vegetation are maintained.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
