Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a bank protection structure for ecological restoration and water purification of a river waterfront zone. Background Art

[0002] Ecological restoration and water purification of river waterfronts have been important research topics in the fields of environmental engineering and soil and water conservation in recent years.

[0003] The Chinese invention patent with announcement number CN106219758A proposes a bank protection structure suitable for ecological restoration and water purification of river and lake waterfronts, including a bank body arranged obliquely along the waterfront and a porous concrete toe located at the toe of the bank body. The bank body includes a geotextile layer, a crushed stone filter layer, a porous concrete base layer and a plant cultivation layer arranged in sequence from bottom to top. A plurality of cross beams are arranged at intervals in the porous concrete base layer. The plant cultivation layer is divided into an upper section, a middle section and a lower section corresponding to the height of the designed highest water level line and the daily water level line. The upper section, the middle section and the lower section are respectively a terrestrial plant nutrient matrix belt, an aquatic plant matrix belt and an algae biofilm matrix belt.

[0004] The above-mentioned revetment structure mainly relies on building planting beds for aquatic plants along the bank. By planting aquatic plants on the planting beds, the purpose of purifying water quality is achieved. This method can improve the ecological environment of the river to a certain extent, but it has some problems and limitations.

[0005] Due to the constant flow of river water, the root systems of newly planted aquatic plants are not yet developed and are easily washed away by the water flow, resulting in plant loss, which not only causes economic losses but also affects the effect of water purification;

[0006] Aquatic plants have a distinct seasonal growth pattern. When plants wither and rot, they need to be replaced with new species. This process requires workers to invest a lot of time in cleaning the planting beds, which is labor-intensive, inefficient, and may cause secondary pollution to the water.

[0007] Therefore, we propose a riverbank protection structure for ecological restoration and water purification of the river waterfront to solve the above problems. Summary of the Invention

[0011] A first filler and a second filler, wherein the first filler is laid on the bottom of the lower half of the rectangular channel, and the second filler is laid on the bottom of the upper half of the rectangular channel;

[0012] The cultivation bin is movably arranged above the first filler and the second filler, the top of the cultivation bin is parallel to the slope of the retaining slope, the bottom of the cultivation bin is a mesh structure, the top of the cultivation bin is constructed with planting channels at equal intervals, and an ecological mat is arranged inside the cultivation bin.

[0013] Furthermore, limiting columns are fixed at equal intervals at the lower end of the rectangular channel.

[0014] Furthermore, the limiting columns are reinforced concrete columns, and the distance between adjacent limiting columns is smaller than the particle size of the first filler.

[0015] Furthermore, the first filler is volcanic rock, and the second filler is ceramsite.

[0016] Furthermore, the ecological mat is a coconut fiber mat.

[0017] Furthermore, rollers are installed at the side corners of the cultivation chamber, and a slide groove is constructed on the inner side wall of the rectangular channel near the upper port, and the rollers are slidably embedded in the slide groove.

[0018] Furthermore, a handle is fixedly provided at one end of the cultivation bin, and a rubber sleeve is provided on the surface of the handle.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model places aquatic plants in a suitable environment and performs pre-cultivation by arranging a cultivation chamber and an ecological mat, thereby ensuring that the plant root systems are well developed, reducing plant loss caused by water flow impact, and improving economic benefits.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0027] The present application provides a riverside ecological restoration and water purification revetment structure, which is mainly used to solve the problem in the prior art that due to the continuous flow of river water, the root systems of newly planted aquatic plants are not yet developed and are easily washed away by the water flow, resulting in plant loss, which not only causes economic losses but also affects the effect of water purification. The following technical solutions are provided. Figure 1-Figure 3 Give detailed instructions:

[0028] A bank protection structure for ecological restoration and water purification of a river waterfront zone, comprising:

[0029] The retaining slope 1 is formed by pouring sand concrete, and rectangular channels 2 are constructed at equal intervals on the inclined surface of the retaining slope 1;

[0030] The first filler 3 and the second filler 4 are laid on the bottom of the lower half of the rectangular channel 2, and the second filler 4 is laid on the bottom of the upper half of the rectangular channel;

[0031] The cultivation bin 5 is movably arranged above the first filler 3 and the second filler 4. The top of the cultivation bin 5 is parallel to the slope of the retaining slope 1. The bottom of the cultivation bin 5 is a mesh structure. The top of the cultivation bin 5 is constructed with planting channels 501 at equal intervals. An ecological mat 6 is arranged inside the cultivation bin 5.

[0032] Workflow Description:

[0033] Phase 1:

[0034] The cultivation chamber 5 is placed in a suitable environment, such as a greenhouse or a nursery, and an ecological mat 6 is laid in the cultivation chamber 5 to provide nutrients and support for the aquatic plants. Then, the aquatic plant seeds or seedlings are planted and initially cultivated until the plant root system is well developed.

[0035] Phase 2:

[0036] Carefully move the pre-cultured culture chamber 5 to the designated location on the embankment, and insert the culture chamber 5 into the rectangular channel 2 on the retaining slope 1, laying it flat on top of the first filler 3 and the second filler 4, and ensure that it is stably fixed;

[0037] Phase 3:

[0038] Maintain the growth of aquatic plants through regular monitoring, utilize their root systems and biological functions to purify water quality, monitor plant growth and water quality changes, and evaluate purification effects;

[0039] Phase 4:

[0040] When the life cycle of the aquatic plants ends or a new species needs to be replaced, the cultivation chamber 5 is taken out from the bank and replaced with a new or re-cultivated cultivation chamber 5 to continue water purification.

[0041] The bank protection structure for ecological restoration and water purification of the stream waterfront zone places aquatic plants in a suitable environment for pre-cultivation by setting up a cultivation chamber 5 and an ecological mat 6 to ensure that the plant root system is well developed, which can reduce the loss of plants caused by water flow impact and improve economic benefits. In addition, the detachable design of the cultivation chamber 5 simplifies the work of replacing plants during seasonal changes, reduces labor intensity, and improves work efficiency. By replacing the cultivation chamber 5, suitable aquatic plants can be planted, which can adapt to different seasons and the replacement of aquatic plant species and continuously optimize the water purification effect.

[0042] It should be noted that the retaining slope 1 is a concrete layer cast on the surface of the embankment, and the cultivation chamber 5 can be made of corrosion-resistant plastic to increase the service life of the equipment.

[0043] like Figure 2 As shown, in some embodiments, limiting posts 202 are fixed at equal intervals at the lower end of the rectangular channel 2. The limiting posts 202 are reinforced concrete posts, and the spacing between adjacent limiting posts 202 is smaller than the particle size of the first filler 3. The limiting posts 202 are fixed at equal intervals at the lower end of the rectangular channel 2. Their main function is to block the cultivation chamber 5 and ensure that it does not fall into the river due to water impact or other external forces. The spacing between the limiting posts 202 is carefully designed to be sufficient to block the cultivation chamber 5 while leaving enough space to not affect the material and energy conversion between the river and the cultivation chamber 5. This ensures that aquatic plants can absorb necessary nutrients from the river water, while also ensuring that microorganisms and chemicals in the water can effectively interact with the plant roots, thereby promoting the natural purification process of water quality.

[0044] like Figure 2As shown, in some embodiments, the first filler 3 is volcanic rock and the second filler 4 is expanded clay. More specifically, volcanic rock, as a natural light stone, has good air permeability and drainage, which helps to keep the root system healthy and avoid water accumulation and root rot. Its porous structure provides a larger surface area, which is suitable for the growth of bacteria and other microorganisms. These microorganisms help to decompose organic matter and promote water purification. The surface of expanded clay can promote better attachment and growth of roots. At the same time, its good water retention helps plants obtain necessary water during droughts. The combined use of these two fillers not only improves the growth conditions of aquatic plants in the cultivation chamber 5, but also enhances the circulation and transformation of matter and energy in the entire ecosystem through its physical and chemical properties.

[0045] like Figure 3 As shown, in some embodiments, the ecological mat 6 is a coconut fiber mat. More specifically, on the one hand, the coconut fiber mat has good air permeability and water retention, providing a good growth environment for the roots of aquatic plants, and its fiber structure helps the roots to attach while maintaining the necessary water and oxygen supply. On the other hand, the porous nature of the coconut fiber mat provides an ideal habitat for microorganisms, which is conducive to the growth and reproduction of beneficial microorganisms in the water. These microorganisms can decompose organic matter and convert elements such as nitrogen and phosphorus, thereby helping to purify water quality. In addition, the coconut fiber mat is an environmentally friendly material that can be naturally degraded in the environment, avoiding secondary pollution of the water body.

[0046] like Figure 2 and Figure 3 As shown, in some embodiments, rollers 7 are installed at the side corners of the cultivation bin 5, and a slide groove 201 is constructed on the inner wall of the rectangular channel 2 near the upper port, and the roller 7 is slidably embedded in the inside of the slide groove 201. More specifically, the rollers 7 are installed at the side corners of the cultivation bin 5, so that the cultivation bin 5 can be easily moved in the rectangular channel 2. This design reduces the labor intensity of manual handling and improves work efficiency, which is particularly convenient when plants need to be replaced seasonally.

[0047] like Figure 3 As shown, in some embodiments, a handle 8 is fixedly provided at one end of the culture chamber 5. The handle 8 is covered with a rubber sleeve. More specifically, the design of the handle 8 allows personnel to easily carry and position the culture chamber 5. When the culture chamber 5 needs to be removed from or inserted into the rectangular channel 2, the handle 8 provides a stable grip, reducing the difficulty of operation. The rubber sleeve on the handle 8 not only increases grip comfort and friction, but also has anti-slip and anti-corrosion properties.

[0048] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
