Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ecological environment engineering, and more particularly to a shallow flow type ecological weir dam structure. BACKGROUND

[0002] In order to develop and utilize water resources and create a landscape belt, more and more fixed weirs or movable weirs are built on natural river channels. The existing weirs are mostly constructed by using concrete or gravel materials, mainly to meet the functions of flood control, water storage and irrigation, and are single in function and form, which causes the fragmentation of river systems, blocks the migration channel of migratory fish and the exchange of nutrients in upstream and downstream water bodies, affects the survival and reproduction of fish, and is poor in hydrophilicity and ecology, and has little effect on controlling non-point source pollution.

[0003] With the emphasis on ecological environment protection and ecological civilization construction, it is particularly important to scientifically carry out river regulation and strengthen pollution prevention, and an ecological weir dam with good landscape effect, strong ecology and water pollution purification function is urgently needed, which can regulate the water level and water volume of the river water body, and has good water purification capacity and ornamental value. SUMMARY

[0004] 1. Technical problem to be solved

[0005] In view of the problems in the prior art, the purpose of the present application is to provide a shallow flow type ecological weir dam structure. In the use process, the dam body is set to be stepped in shape, so that the water splashes flow down from one step to another, increasing the ornamental value of the outside and the scenic spot of the place, and through the multiple water permeable holes and the water flowing slope opened at the side end of the dam body, the water flow can pass through the water permeable holes and the water flowing slope and fall down one step after another, so as to regulate the water level and water volume of the flowing water, play the roles of irrigation, adjustment of slope, consolidation of silt and flood control, and at the same time, improve and govern the surrounding ecological environment, and under the action of lotus, the content of total phosphorus, total nitrogen, BOD5 and CODcr in the water body can be reduced, the content of dissolved oxygen in the water body can be increased, and the water quality can be purified. And in each growth period of lotus, the water purification capacity is the strongest in the flowering period, so that the water flowing from the weir dam can be more clean, and under the limiting effect of the partition plate, the sundries on the water surface can be retained, facilitating the subsequent cleaning of the floating objects on the water surface.

[0006] 2. Technical scheme

[0007] To solve the above problems, the present application adopts the following technical scheme.

[0008] A shallow-flow ecological weir structure includes a river channel, and several dam bodies arranged along the flow direction of the shallow-flow river channel are installed between the inner walls of the river channel. The dam bodies are made of a four-step shape and are arc-shaped. Multiple evenly distributed permeable holes are opened on the side ends of the dam bodies, and multiple flow slopes arranged along the inclined surfaces are fixedly connected to the upper end of the dam bodies.

[0009] Furthermore, the uppermost part of the dam body is embedded with multiple evenly distributed stepping stones.

[0010] Furthermore, the upper end of the stepping stone is embedded with multiple evenly distributed anti-slip strips, which are arranged in an inverted "S" shape.

[0011] Furthermore, a first through hole is provided at the upper end of the water slope, and a second through hole is provided at both the left and right ends of the water slope. A permeable plate is installed between the inner walls of the first through hole. The permeable plate is made of permeable concrete. Lotus flowers are planted inside the water slope, and a filter screen is installed between the inner walls of the second through holes.

[0012] Furthermore, a connecting plate is fixedly connected to the outer end of the dam body, and a partition is fixedly connected to the outer end of the connecting plate. The partition is made of permeable concrete material.

[0013] Furthermore, the water-permeable holes are arranged at an angle, and the inner wall is provided with a polymer hydrophobic coating.

[0014] Furthermore, the filter screen is made of stainless steel and has an anti-rust coating on its surface.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of this invention are:

[0017] (1) In order to make the shallow flow type ecological weir structure have good aesthetic appeal during use, in this embodiment, the dam body is set into a stepped shape, so that water can flow down the steps one by one, which increases the aesthetic appeal and adds to the local landscape. Furthermore, by opening multiple permeable holes and water slopes on the side of the dam body, the water can flow down the steps one by one through the permeable holes and water slopes, thereby regulating the water level and volume of the flowing water. This can play a role in irrigation, adjusting the slope, consolidating sediment, and flood control. At the same time, it can also improve and manage the surrounding ecological environment.

[0018] (2) During the use of this scheme, when water flows downward through the upper end of the dam, as the water slides across the surface of the flow slope, because the permeable concrete material of the seepage board allows some of the water to seep into the interior of the flow slope through the area between the seepage board and the water flowing to the dam surface, it also simultaneously passes through the filter screen into the interior of the flow slope. This provides moisture to the lotus flowers, and under the influence of the lotus flowers, the content of total phosphorus, total nitrogen, BOD5, and CODcr in the water can be reduced, while the content of dissolved oxygen in the water can be increased, thus purifying the water quality. Furthermore, the lotus flowers have the strongest water purification ability during their peak blooming period, making the water flowing from the dam cleaner.

[0019] (3) During the use of this solution, when there are floating objects and impurities on the water surface, the impurities are carried to the surface of the connecting plate above the dam by the flow of water. The impurities are limited by the baffle plate, causing the impurities to be retained, while the water flow can continue to flow downward through the baffle plate made of permeable concrete. The impurities retained above the connecting plate are purified by the lotus flowers, preventing the continuous growth of bacteria from polluting the water flow. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example:

[0028] Please see Figures 1-4 A shallow-flow ecological weir structure includes a river channel 1. Several dam bodies 2 are installed between the inner walls of the river channel 1, arranged along the flow direction of the shallow-flow river channel. The dam bodies 2 are made of a four-step shape and are arc-shaped. Multiple evenly distributed permeable holes 9 are opened on the side ends of the dam bodies 2. Multiple flow slopes 4 arranged along the inclined surface are fixedly connected to the upper end of the dam bodies 2.

[0029] In order to make the shallow-flow ecological weir structure aesthetically pleasing during use, in this embodiment, the dam body 2 is designed as a stepped shape, allowing water to flow down the steps one by one, increasing its visual appeal and enhancing the local landscape. Furthermore, by using multiple permeable holes 9 and a water slope 4 on the side of the dam body 2, the water can flow down the steps one by one, regulating the water level and volume. This allows the dam to play a role in irrigation, slope adjustment, sediment stabilization, and flood control, while also improving and managing the surrounding ecological environment.

[0030] Please see Figures 1-3 The uppermost part of the dam body 2 is embedded with multiple evenly distributed stepping stones 3.

[0031] During use, this scheme creates a walking path between the river channels by embedding multiple stepping stones 3 on the top of the dam body 2 (located on the side above the water surface). This allows pedestrians to walk on top of the stones, and the multiple stepping stones 3 also control the flow of water, reducing the flow rate and increasing the overall aesthetics of the dam.

[0032] Please see Figure 3 The upper end of the stepping stone 3 is embedded with multiple evenly distributed anti-slip strips 12, which are arranged in an inverted "S" shape.

[0033] During use, this solution incorporates multiple anti-slip strips 12 embedded at the upper end of the stepping stone 3, which increases the friction between the sole of a pedestrian's shoe and the stepping stone 3 when walking on it. This prevents the safety hazard of "slipping" due to the smoothness of the stepping stone 3 and the presence of water stains on its surface, thereby improving walking safety.

[0034] Please see Figures 1-2 and Figure 4 The upper end of the water slope 4 is provided with a first through hole 5, and the left and right ends of the water slope 4 are provided with second through holes 6. A permeable plate 7 is installed between the inner walls of the first through hole 5. The permeable plate 7 is made of permeable concrete. Lotus flowers 8 are planted inside the water slope 4. A filter screen 13 is installed between the inner walls of the second through holes 6.

[0035] In the use process of the scheme, when the water flows downward through the upper end of the dam body 2, the water flows from the surface of the water flow slope 4, and part of the water flows between the range of the water seepage plate 7 to the inside of the water flow slope 4, and part of the water flowing on the surface of the dam body 2 also synchronously enters the inside of the water flow slope 4 through the filter screen 13, thereby supplying water to the lotus 8, and under the action of the lotus 8, the contents of total phosphorus, total nitrogen, BOD5, and CODcr in the water body can be reduced, and the content of dissolved oxygen in the water body can be increased, thereby purifying the water quality. In addition, the lotus has the strongest water quality purification ability in the flowering period, so that the water flowing from the weir dam can be more clean.

[0036] Please refer to Figures 1-2 and Figure 4 The outer end of the dam body 2 is fixedly connected with the connecting plate 10, the outer end of the connecting plate 10 is fixedly connected with the partition plate 11, and the partition plate 11 is made of water-permeable concrete material.

[0037] In the use process of the scheme, when there are floating objects and impurities and other pollutants on the water surface, the impurities will be driven to the surface of the connecting plate 10 above the dam body 2 along with the flow of the water, and the impurities can be retained by the limiting effect of the partition plate 11, and the water can continue to flow downward through the partition plate 11 made of water-permeable concrete material, and the impurities retained above the connecting plate 10 are simultaneously purified by the bacteria bred by the lotus 8, thereby avoiding the pollution of the water flow caused by the continuous breeding of the bacteria;

[0038] In addition, the water-permeable concrete in the embodiment is also called porous concrete or sand-free concrete, and water-permeable pavement. It is a kind of porous lightweight concrete mixed by aggregate, cement, water, and reinforcing agent, etc. However, it is different from ordinary cement soil in that it does not contain fine aggregate.

[0039] Because it does not contain fine aggregate, but is made of coarse aggregate and other mixtures, the water-permeable concrete is generally a porous structure, and the pore gap diameter is more than 1mm, which is larger than that of ordinary concrete, so the water-permeable concrete has the characteristics of air permeability, water permeability, and light weight. In addition, the water-permeable concrete has the same strength as ordinary concrete, and has a porous structure, so the drainage speed is particularly fast, and can withstand a water flow of 36000mm / hour.

[0040] Please refer to Figure 4 The water-permeable hole 9 is arranged in an inclined manner, and the inner wall is provided with a high-molecular hydrophobic coating.

[0041] In the use process, the water-permeable hole 9 is arranged in an inclined shape and is arranged on the side end surface of the dam body 2, so that the water flow is more smooth, and the high polymer hydrophobic coating arranged on the inner wall can prevent scale and moss from being generated on the inner wall of the water-permeable hole 9, and the internal blockage phenomenon is avoided.

[0042] Please refer to Figure 4 The filter screen 13 is made of stainless steel and is provided with a rust-proof coating.

[0043] In the use process, the filter screen 13 is made of stainless steel and is provided with a rust-proof coating, so that the filter screen 13 is not easily corroded and rusted after long-time use, and the pollution of the water flow and the lotus 8 caused by rust on the filter screen 13 is avoided.

[0044] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the improved concept of the present application within the technical range disclosed by the present application, and all of them should be covered in the protection scope of the present application.
