Description

Technical Field

[0001] This utility model relates to the field of ecological wall technology, and in particular to an ecological wall for water conservancy projects. Background Technology

[0002] Ecological walls in water conservancy projects are a new type of engineering structure that integrates water conservancy protection and ecological restoration functions. They are usually based on permeable materials such as porous concrete, ecological bags, and mesh cages. By reserving pores for plant growth or directly planting native herbaceous and shrub vegetation, a composite system of "engineering protection + ecological symbiosis" is constructed.

[0003] Traditional water conservancy ecological walls have obvious limitations in responding to dynamic changes in water levels. During the flood season, high water levels can cause continuous impact on rigid structures, and long-term use can lead to structural wear and leakage, increasing maintenance costs. During the drought season, when water levels drop, the lack of an effective water supply mechanism in the coastal area causes the surrounding vegetation to wither, further exacerbating soil erosion and ecological degradation. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological wall for water conservancy projects, which improves the stability of the ecological wall, helps prevent soil erosion, and avoids plant death during drought.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ecological wall for water conservancy projects, including a vertical wall, wherein an overflow pipe is installed through the vertical wall near the top, so that water can flow from one side of the vertical wall to the other side through the overflow pipe; A concrete slope is provided on the water-facing side of the vertical wall, a permeable concrete cushion layer is provided on the water-facing side of the concrete slope, and a planting layer is provided on the permeable concrete cushion layer. A water storage tank and a water pump are installed on the back side of the vertical wall. The inlet and outlet ends of the water pump are connected to a riser and a bend, respectively. One end of the riser extends to the bottom of the water storage tank, and one end of the bend penetrates the vertical wall and is located above the planting layer.

[0006] In some embodiments, steps are provided on the surface of the concrete slope.

[0007] In some embodiments, reinforcing piles are integrally installed within the concrete slope.

[0008] In some embodiments, a plurality of partitions are fixedly installed on the permeable concrete subbase, the partitions are perpendicular to the permeable concrete subbase, and a pressure plate is provided on the top of the partition, the pressure plate pressing on the upper surface of the planting layer.

[0009] In some embodiments, the planting layer is planted with aquatic, wetland and xerophytic plants in sequence from bottom to top along the height direction.

[0010] In some embodiments, a protective net is provided inside the water storage tank, the protective net being arranged near and parallel to the bottom of the water storage tank, and the riser extending below the protective net.

[0011] In some embodiments, a warning button is provided on the inner wall of the water storage tank, and a light strip is provided on the outer wall of the water storage tank. The warning button is the switch for the light strip. The warning button is arranged opposite to the outlet of the overflow pipe, so that the water flowing out of the overflow pipe can impact the warning button, thereby illuminating the light strip.

[0012] In some embodiments, a groove is formed on the inner wall of the water storage tank, and the warning button is arranged in the groove. The warning button includes a pressing plate, a compression spring, and a spring-type button switch. The spring-type button switch and the compression spring are both fixed to the bottom of the groove. The pressing plate is elastically connected to the bottom of the groove through the spring, and the pressing plate is in sealed sliding contact with the inner wall of the groove.

[0013] In some embodiments, a water guide cover is provided at one end of the overflow pipe near the water-facing side of the vertical wall.

[0014] Furthermore, a filter screen is provided on the water guide cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The concrete slope and the vertical wall of this utility model are cast in one piece and reinforced with internal piles, which significantly improves the stability of the overall structure and its resistance to water flow impact, and extends the service life of the project.

[0016] 2. The permeable concrete subbase of this invention combines structural strength with permeability, protecting the slope surface while buffering water flow and promoting infiltration. Its rough surface also enhances the bonding force with the planting soil, preventing soil slippage. Simultaneously, a pressure plate is installed on top of the partition to further stabilize the planting layer and prevent soil erosion.

[0017] 3. This utility model divides the planting layer into multiple planting areas by setting up partitions and configuring different proportions of planting soil for different height areas, realizing the zoned planting of aquatic, wetland and drought-tolerant plants, which is conducive to building a composite ecosystem and enhancing the ecological function and landscape diversity of the wall.

[0018] 4. The overflow pipe of this utility model can automatically divert water to the storage tank when the water level rises, preventing water from overflowing the wall and avoiding waterlogging damage to the structure and xerophytes. At the same time, during the dry season, the water stored in the storage tank can be pumped back for plant irrigation, which not only makes effective use of water resources, but also avoids plant death and soil erosion during the dry season, thus improving the environmental adaptability and sustainability of the ecological wall.

[0019] 5. This utility model uses water flow impact to trigger a spring-loaded push-button switch, controlling the light strip to illuminate and achieving a remote visual alarm for rising liquid level. This allows maintenance personnel to promptly grasp the water flow situation and take countermeasures, improving the level of intelligent engineering management. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, this utility model provides an ecological wall for water conservancy projects, including a vertical wall 3. A concrete slope 1 is provided on the water-facing side of the vertical wall 3. The concrete slope 1 can be integrally cast with the vertical wall 3. Steps are provided on the slope surface of the concrete slope 1. A permeable concrete cushion layer 4 is laid on the steps. A planting layer 5 is provided on the permeable concrete cushion layer 4. The permeable concrete cushion layer 4 serves as a transition layer, which has a certain structural strength to protect the concrete slope 1, and can also achieve water permeability and buffer water flow through pores. At the same time, the rough surface can enhance the bonding stability with the soil of the planting layer 5.

[0024] Multiple partitions are fixedly installed on the permeable concrete subbase 4, with the partitions perpendicular to the permeable concrete subbase 4. A pressure plate 6 is installed on the top of the partition, pressing the upper surface of the planting layer 5, which can stabilize the planting layer 5 to a certain extent. The partitions divide the planting layer 5 into multiple planting areas. Different types of plants are planted in planting areas at different heights, and different planting soils are used. For example, from bottom to top, the planting soils are selected as river mud + humus + coarse sand, garden soil + peat moss + perlite mixed substrate, and garden soil + leaf mold + vermiculite mixed substrate, respectively, so as to realize the zoned planting of aquatic, wetland and drought-tolerant plants and form a composite ecosystem.

[0025] To further improve the stability of the vertical wall 3 and the concrete slope 1, reinforcing piles 2 are installed inside the concrete slope 1 to enhance its resistance to water flow impact.

[0026] like Figure 1 As shown, an overflow pipe 7 runs through the top of the vertical wall 3. The left end of the overflow pipe 7 is the water inlet, and the right end is the water outlet. A water guide cover 8 is fixedly connected to the left end of the overflow pipe 7, and a filter screen is snapped onto the end face of the water guide cover 8.

[0027] like Figure 1 As shown, a water storage tank 9 is poured on the back side of the vertical wall 3. A water pump 12 is fixedly installed on the side wall of the vertical wall 3. The inlet and outlet ends of the water pump 12 are connected to a riser 11 and a bend 13, respectively. One end of the riser 11 extends to the bottom of the water storage tank 9, and one end of the bend 13 penetrates the vertical wall 3 and is located above the planting layer 5. A protective net 10 is fixedly connected to the bottom of the inner wall of the water storage tank 9, and the bottom of the riser 11 penetrates the protective net 10.

[0028] like Figure 2 As shown, a groove is provided on the inner wall of the top of the water storage tank 9 on the side away from the vertical wall 3. A pressing plate 15 is movably embedded in the top of the groove. The pressing plate 15 is connected to the bottom of the groove by a compression spring 16. A spring-type push button switch 17 is fixedly connected to the bottom of the groove. A light strip 14 is fixedly connected to the outer wall of the water storage tank 9. The light strip 14 is electrically connected to an external power supply through the spring-type push button switch 17.

[0029] When the ecological wall of this water conservancy project is in use, when the liquid level gradually rises to the height of the overflow pipe 7, the water can flow through the overflow pipe 7 into the water storage tank 9, thereby reducing the liquid level on the water-facing side of the vertical wall 3, preventing water from overflowing the vertical wall, and preventing most of the structure and xerophytic plants from being soaked in water. During the overflow process, impurities and foreign objects in the water will be blocked by the filter screen. At the same time, the overflowing water sprays out from one end of the overflow pipe 7. The water flow impacts the pressing plate 15. The impact force of the water flow causes the internal compression spring 16 to compress. The pressing plate 15 presses down and squeezes the internal spring-type button switch 17, triggering the light strip 14 to light up. Maintenance personnel can visually know from a distance that the liquid level has risen and the diversion stage is underway by observing the light strip 14. If the light strip 14 continues to light up for a long time, maintenance personnel can take other diversion measures to avoid the water flow from continuously damaging the ecological wall. During the overflow process, the water in the reservoir 9 is collected. The reservoir 9 can also collect rainwater. During drought periods, when the water level drops, the water pump 12 can be turned on to pump the water stored in the reservoir 9 into the bend pipe 13, guiding the water flow to the water-facing side of the vertical wall 3, providing a suitable water environment for the plants, preventing large-scale plant death during droughts, and preventing soil erosion. Of course, if there is no water in the reservoir 9, water can be drawn from the outside into the reservoir 9, and then pumped to the water-facing side of the vertical wall 3 using the water pump 12.
