Description

Technical Field

[0001] This application relates to the field of water conservancy engineering technology, and in particular to an eco-friendly embankment for urban rivers. Background Technology

[0002] Urban river ecology refers to the protection and restoration of the natural environment and biodiversity of river ecosystems during the urbanization process. It emphasizes that river management and control should not only focus on water quality, quantity, and flood control functions, but also on protecting and restoring the ecological environment, promoting the survival and reproduction of aquatic plants and animals, and maintaining the ecological balance of the river. The connection between urban river ecology and embankments lies in the fact that embankments, as one of the infrastructure components of rivers, need to consider ecological protection in addition to their functions of flood control, irrigation, and water resource management, avoiding damage to aquatic ecosystems. Using eco-friendly embankments for urban rivers can effectively promote soil and water conservation, ecological restoration, and biodiversity, reduce soil erosion, inhibit erosion, improve embankment stability, and also improve the surrounding environmental quality, promoting the sustainable development of the ecological environment. In short, such embankments not only ensure urban flood control safety but also support ecological restoration, contributing to the harmonious coexistence of cities and nature.

[0003] A search revealed Chinese patent publication number CN213653343U, which discloses an eco-friendly embankment for urban rivers. The embankment includes a road surface fixedly connected to its top, a gabion mesh fixedly connected to the right side of the road surface, a soil layer fixedly connected to the right side of the gabion mesh, and ecological slope protection bricks laid on the right side of the soil layer. Green plants are planted inside the ecological slope protection bricks. A water pump box is located at the bottom of the right side of the soil layer, and a water pump is fixedly connected inside the water pump box. A water outlet pipe, on the side away from the water pump, passes through the gabion mesh and the soil layer sequentially and connects to a sprinkler head. This utility model, through the coordinated use of the embankment, road surface, soil layer, gabion mesh, sprinkler head, water outlet pipe, water pump box, water pump, guide lights, guardrails, stone road surface, fixing poles, erosion protection layer, water inlet pipe, steps, ecological slope protection bricks, green plants, and concrete layer, has the advantages of maintaining good growth of green plants, facilitating embankment reinforcement, and providing convenient recreational facilities.

[0004] The aforementioned patent specification mentions "an eco-friendly embankment for urban rivers, comprising an embankment, a road surface fixedly connected to the top of the embankment, a gabion mesh fixedly connected to the right side of the road surface, a soil layer fixedly connected to the right side of the gabion mesh, ecological slope protection bricks laid on the right side of the soil layer, green plants planted inside the ecological slope protection bricks, a water pump box set at the bottom of the right side of the soil layer, a water pump fixedly connected inside the water pump box, and a water outlet pipe passing through the gabion mesh and the soil layer in sequence and connected to a sprinkler on the side away from the water pump." However, the text does not describe whether the irrigation system can continue to work under drought conditions. This means that the irrigation system will lose its original function during drought, thus putting pressure on the growth of ecological green plants. Utility Model Content

The overall design not only enhances pedestrian comfort and safety but also provides additional lighting at night, further optimizing the functionality and user experience of the embankment and demonstrating comprehensive consideration for pedestrian safety.

[0018] As a further description of the above technical solution: the cement layer has multiple hexagonal grooves inside, and multiple ecological slope protection bricks are fixedly connected inside the hexagonal grooves. The ecological slope protection bricks are hexagonal blocks.

[0019] The above-described solution involves incorporating multiple hexagonal grooves within the cement layer, and fixing ecological slope protection bricks within these grooves. The hexagonal design of the slope protection bricks allows for better integration with the surrounding environment. This hexagonal structure not only enhances overall stability but also effectively disperses the impact of water flow, reducing soil erosion. The ecological slope protection bricks promote plant growth, ecological restoration, and soil quality improvement, further enhancing the ecological function of the dam.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. In this utility model, when planting greenery on ecological slope protection bricks, a water pump located inside the dam body is activated, drawing river water through the second and first inlet pipes. During this process, due to the bidirectional extraction through the second and first inlet pipes, water flow can be adjusted according to different water levels to adapt to drought conditions. The water is then guided through the main outlet pipe to the branch outlet pipe, which in turn guides the water flow to the main irrigation pipe. The branch irrigation pipe then guides the water flow to the sprinkler heads, which ultimately irrigate the greenery on the ecological slope protection bricks, thereby reducing the difficulty of greenery growth and planting, and thus mitigating soil erosion within the ecological slope protection bricks.

[0026] 2. In this utility model, when the water level drops to a certain level, the suspended airbag rotates under the restriction of the connecting shaft due to the drop in water level and the weight of the counterweight ball inside the suspended airbag. This eventually causes the suspended airbag to block the inlet of the first water inlet pipe, thereby preventing the inlet of the first water inlet pipe from being exposed to the air due to the drop in water level, which would affect the pumping effect of the water pump and ultimately affect the growth of the green plants.

[0033] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0034] Example 1: An eco-friendly embankment for urban rivers, referring to... Figure 2 , Figure 4 , Figure 5The structure includes the dam body 1, which is the core supporting part of the entire structure. Its main function is to provide flood control and protect the stability of both banks of the river. An anti-erosion layer 11 is fixedly connected to the right side of the dam body 1. The anti-erosion layer 11 is located on the right side of the dam body 1 and its main function is to prevent water flow from eroding the dam surface. A drought prevention mechanism 4 is fixedly connected to the right side of the anti-erosion layer 11. The drought prevention mechanism 4 is installed on the right side of the anti-erosion layer 11 and its main function is to prevent the dam from drying out by controlling the amount of water flow. A gabion layer 7 is fixedly connected to the top of the dam body 1. The gabion layer 7 is a protective layer on top of the dam and is mainly composed of a metal mesh structure filled with sturdy materials such as stones. A cement layer 8 is fixedly connected to the top of the gabion layer 7, covering the gabion layer 7 and fixing ecological slope protection bricks 9 through multiple hexagonal grooves. A water supply mechanism 2 is fixedly connected inside the dam body 1. A walkway 5 is fixedly connected to the top of the dam body 1. The walkway 5 is designed to provide a safe passage for workers, and also includes guardrails 6. To ensure the safety of the dam, an installation groove is provided in the middle of the cement layer 8, and a step 12 is provided inside the installation groove. A water guide block 10 is fixedly connected to the bottom right side of the cement layer 8, and a water guide channel is provided inside the water guide block 10. A guardrail 6 is fixedly connected to the top of the walkway 5, and a light is provided at the top of the guardrail 6 to ensure safety during nighttime operations. The guardrail 6 is also equipped with a light at the top. Multiple hexagonal grooves are provided inside the cement layer 8, and multiple ecological slope protection bricks 9 are fixedly connected inside the hexagonal grooves. The ecological slope protection bricks 9 are hexagonal blocks designed for soil and water conservation and ecological restoration around the dam. The dam body 1 has a maintenance groove inside, which is a space for maintaining the water pump 23 inside the dam. The water pump 23 can be inspected and maintained through the maintenance groove. The outside of the water pump 23 is fixedly connected to the inside of the maintenance groove. The bottom of the protective block 26 is slidably connected to the top of the maintenance groove. A through hole is provided inside the water guide block 10, and the top of the maintenance groove corresponds to the bottom of the through hole.

[0035] Specifically, firstly, the water supply mechanism 2 provides water to the dam through a pipeline system inside the dam body 1, ensuring the moisture of the ecological slope protection bricks 9 and the surrounding environment. The cement layer 8 fixes the ecological slope protection bricks 9 through multiple hexagonal grooves, contributing to soil and water conservation and ecological restoration. The water guide block 10 guides the water flow, effectively draining water through its internal drainage channels, maintaining the stability of the dam structure. The anti-erosion layer 11 and the drought prevention mechanism 4 protect the dam from external erosion and drought. The combination of the gabion layer 7 and the cement layer 8 enhances the physical strength of the dam, and the guardrail 6 provides safety. The water pump 23 in the maintenance trench can be activated when water is needed to maintain the dam's soil and water conservation. The pedestrian walkway 5 provides a safe passage for workers, while lighting ensures visibility for nighttime operations.

[0036] The water supply mechanism 2 includes a second inlet pipe 21, which is externally fixedly connected to the inside of the dam body 1. A first inlet pipe 22 is fixedly connected to the top of the second inlet pipe 21. A water pump 23 is fixedly connected inside the dam body 1. The main function of the water pump 23 is to introduce external water into the dam to provide sufficient water for the ecological slope protection bricks 9 and the surrounding environment. The first inlet pipe 22 is externally fixedly connected to the inside of the inlet of the water pump 23. A main outlet pipe 24 is fixedly connected inside the output end of the water pump 23. A water outlet diversion pipe 25 is fixedly connected to the top of the main outlet pipe 24. A water spray assembly 3 is fixedly connected to the outside of the water outlet diversion pipe 25. A protective block 26 is slidably connected inside the walkway 5. The protective block 26 provides a sliding connection to ensure that the position can be safely adjusted during maintenance. The top of the water pump 23 is located at the bottom of the protective block 26.

[0037] Specifically, firstly, the second inlet pipe 21 introduces water into the dam body 1, and the water enters the water pump 23 through the first inlet pipe 22. After the water pump 23 starts, it draws water in from the inlet and delivers it to the outlet main pipe 24 through the outlet end. Subsequently, the water flow is distributed to the outlet diversion pipe 25. The outlet diversion pipe 25 guides the water flow to the sprinkler assembly 3, where the water is sprayed evenly to achieve irrigation, cleaning, and other purposes. At the same time, the protective blocks 26 within the walkway 5 provide flexible protection and adjustment functions through sliding connections to ensure future maintenance of the water pump 23.

[0038] The water spray assembly 3 includes an irrigation main pipe 31, which is responsible for distributing water from the water pump 23 to multiple branch pipes, and then spraying the water evenly to the environment around the dam through the nozzles 33. The outside of the irrigation main pipe 31 is fixedly connected to the inside of the water outlet pipe 25. Multiple irrigation branch pipes 32 are fixedly connected to the top of the irrigation main pipe 31, and nozzles 33 are fixedly connected to the top of the irrigation branch pipes 32.

[0039] Specifically, water is delivered to the main irrigation pipe 31 via the outlet pipe 25. The main irrigation pipe 31 distributes the water flow to multiple irrigation branch pipes 32. Each irrigation branch pipe 32 is fixedly connected to a sprinkler head 33, which adjusts the water flow and spray angle as needed to evenly spray water onto the designated area for irrigation. The entire system, through precise water distribution and spraying, ensures the moisture of the environment around the dam, contributing to ecological restoration and soil and water conservation. This workflow effectively utilizes water resources, supporting the stability and development of the ecosystem within the dam.

[0040] Reference Figure 1 , Figure 3The drought prevention mechanism 4 includes two fixed shafts 42. The left side of the two fixed shafts 42 is fixedly connected to the right side of the anti-corrosion layer 11. The two fixed shafts 42 are rotatably connected to the inside of the two fixed shafts 42. The inside of the two connecting shafts 41 and the inside of the two fixed shafts 42 are rotatably connected to the rotating shafts 43. The bottom of the two connecting shafts 41 is fixedly connected to the suspended airbags 44. Multiple counterweight balls 45 are slidably connected inside the two suspended airbags 44. The counterweight balls 45 in the drought prevention mechanism 4 are slidably connected inside the airbags. As the water flow changes, the relative position of the counterweight balls 45 will change, thereby adjusting the buoyancy of the airbags. The outside of the upper counterweight ball 45 is slidably connected to the inside of the inlet of the first water inlet pipe 22. The outside of the lower counterweight ball 45 is slidably connected to the inside of the inlet of the second water inlet pipe 21. The inside of the fixed shafts 42 is provided with a rotating groove. The outside of the connecting shafts 41 is rotatably connected to the inside of the rotating groove. The top of the connecting shafts 41 is rounded.

[0041] Specifically, the drought-resistant mechanism 4 is installed on the right side of the anti-erosion layer 11 via a fixed shaft 42. The fixed shaft 42 is internally connected to a rotating shaft 43 and a connecting shaft 41. The connecting shaft 41 is rotatably connected to the fixed shaft 42 via a rotating groove, and its top is rounded to ensure smooth movement. A suspended airbag 44 is fixed to the bottom of each connecting shaft 41, and multiple counterweight balls 45 are slidably connected inside the airbag. The counterweight balls 45 slide vertically, with the upper counterweight ball 45 slidably connected to the inlet of the first water inlet pipe 22, and the lower counterweight ball 45 slidably connected to the inlet of the second water inlet pipe 21. As the water flow changes, the relative movement of the suspended airbag 44 and the counterweight balls 45 adjusts the buoyancy and position of the airbag, thereby achieving dynamic adjustment of the mechanism through the rotation of the rotating shaft 43 and the connecting shaft 41. This system, through precise buoyancy and counterweight adjustment, automatically responds to environmental changes, ensuring the continuous and stable drought-resistant effect.

[0042] The implementation principle of this application embodiment is as follows:

[0043] In use, the anti-erosion layer 11 fixedly connected to the right side of the dam body 1 achieves the separation of the dam body 1 and the water flow, thereby preventing the water flow from eroding the dam body 1 and making the dam body 1 prone to collapse. The sidewalk 5 fixed to the top of the dam body 1 provides convenience for people to walk, and the guardrail 6 fixed to the top of the sidewalk 5 can prevent people from falling into the river due to accidents while walking.

[0044] The gabion layer 7, fixed to the top of the dam body 1, connects with the dam body 1. The gabion layer 7 and the cement layer 8 work together to isolate the dam body 1 from external rainwater corrosion, further reducing the possibility of dam body 1 collapsing. Then, the water pump 23 fixed inside the dam body 1 is started. Water from the river is drawn into the water pump 23 through the first inlet pipe 22 fixedly connected inside the water pump 23 inlet and the second inlet pipe 21 fixed inside the first inlet pipe 22. Then, water is drawn into the water pump 23 through the water pump 23 output end. The main water outlet 24 guides the water flow into the interior of the water outlet branch pipe 25. Multiple irrigation main pipes 31 fixed to the outside of the water outlet branch pipe 25 guide the water flow to the irrigation branch pipe 32. Finally, the water flow is sprayed out through the nozzle 33 fixed to the top of the irrigation branch pipe 32, thereby watering multiple ecological slope protection bricks 9 fixed inside the cement layer 8, thus reducing the difficulty of planting greenery and promoting the growth of greenery on the ecological slope protection bricks 9. The protective block 26 slidably connected to the top of the sidewalk 5 provides convenience for subsequent maintenance of the water pump 23.

[0045] When the water level drops to a certain level, the suspended airbag 44, which is fixed to the right side of the anti-corrosion layer 11 by the fixed shaft 42, rotates around the internal rotation shaft 43 of the fixed shaft 42 under the guidance of the connecting shaft 41 due to the drop in water level and the weight of the counterweight ball 45 inside the suspended airbag 44. This causes the suspended airbag 44 to block the water inlet opened inside the first water inlet pipe 22, thereby preventing the first water inlet pipe 22 from being exposed to air due to the drop in water level, which would reduce the water absorption effect of the second water inlet pipe 21.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
