Description

Technical Field

[0001] This utility model relates to the field of river ecological management technology, specifically to an ecological embankment suitable for river restoration and management. Background Technology

[0002] Modern dams are mainly divided into earth-rock dams and concrete dams. Earth-rock dams are wide dams built with earth or stone, and are mostly built across large rivers. They use common and inexpensive materials, and because the materials are relatively loose, they can withstand the swaying of the foundation. Concrete dams are mostly built with concrete and are usually constructed in deep and narrow valleys because only concrete can withstand the high water pressure at the base of the dam. The main characteristic of concrete dams is that they use their own weight to support the water pressure. In recent years, large dams have adopted high-tech reinforced concrete construction.

[0003] The comparative document, "An Ecological Embankment Applicable to River Restoration and Management," Publication No. (CN222540631U), describes a method that uses a water pump to draw water from the riverbed into a collection trough. The water flows through the collection trough to a fixed plate, where it penetrates a soft filter mat. The water then flows along the embankment to an inclined chute, which lifts the water, causing it to fall back onto the river surface, thus creating an aeration effect. This increases the oxygen content of the river water, improving its restoration and management. As the water flows through the soft filter mat, it is filtered and allowed to seep into the planting racks, facilitating water absorption by the plants. In this system, the system achieves water extraction and filtration, followed by water restoration through plant cultivation, and also provides aeration, increasing the oxygen content and enhancing the overall effectiveness of river restoration and management.

[0004] However, when used, ecological dams cannot effectively filter the water flow in the river, making it difficult to improve water quality and causing inconvenience to users, thus failing to meet their needs. Utility Model Content

[0005] The purpose of this utility model is to provide an ecological embankment suitable for river restoration and management, in order to solve the problem mentioned in the background art that the ecological embankment cannot effectively filter the water flow in the river, resulting in difficulty in improving water quality, causing inconvenience to users, and no longer meeting the needs of users.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological dam suitable for river restoration and management, comprising a dam body, a filter groove is provided on one side of the top of the dam body, a water filtration assembly is fixedly installed inside the filter groove, a cavity is provided inside the water filtration assembly, a filter screen is fixedly installed in the middle of the water filtration assembly, a permeable layer is fixedly installed on the top of the filter screen, a filtration layer is fixedly installed on the bottom of the filter screen, a conical water-dispersing plate is fixedly installed on the top of the water filtration assembly, a photocatalytic coating is fixedly installed on the outer surface of the conical water-dispersing plate, and a planting trough is provided on the other side of the top of the dam body.

[0007] Furthermore, the number of filter tanks is three, and the filter tanks and the water filtration assembly are integrated into one unit.

[0008] Furthermore, the permeable layer is made of porous concrete blocks, and the pore size of the porous concrete blocks is 10-30mm.

[0009] Furthermore, the filter layer is made of a zeolite and biochar composite material with a particle size of 5-10 mm.

[0010] Furthermore, the number of the conical water-dispersing plates is several, and the distance between each pair of conical water-dispersing plates is equidistant.

[0011] Furthermore, the planting troughs are of several kinds, and each pair of planting troughs is designed to be equidistant from each other.

[0012] Furthermore, a water guide pipe is connected to the bottom of the filter tank, and one end of the water guide pipe penetrates the dam body and extends to its exterior.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This ecological embankment, suitable for river restoration and management, purifies water flow by incorporating a permeable layer, a filter layer, a photocatalytic coating, and a filter screen. This process eliminates harmful substances in the water, improves water quality, accelerates the restoration of the river's ecological environment, provides convenience to users, enhances the device's practicality, and meets user needs.

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an ecological dam suitable for river restoration and management, including a dam body 1. The dam body 1 is used to set corresponding components. A filter groove 2 is opened on one side of the top of the dam body 1. The filter groove 2 is used to set a water filtration component 3. The water filtration component 3 is fixedly installed inside the filter groove 2. The water filtration component 3 can filter the water flow. The water filtration component 3 has a cavity inside. A filter screen 4 is fixedly installed in the middle of the water filtration component 3. The filter screen 4 acts as a barrier. A permeable layer 5 is fixedly installed on the top of the filter screen 4. The permeable layer 5 is used to filter larger impurities. A filter layer 6 is fixedly installed at the bottom of the filter screen 4. The filter layer 6 can filter the water quality. A conical water-dispersing plate 7 is fixedly installed on the top of the water filtration component 3. The conical water-dispersing plate 7 can reduce the impact of the water flow. A photocatalytic coating 8 is fixedly installed on the outer surface of the conical water-dispersing plate 7. The photocatalytic coating 8 can carry out an oxidation-reduction reaction and can treat the water quality. A planting trough 9 is opened on the other side of the top of the dam body 1. The planting trough 9 is used to plant green plants.

[0022] Furthermore, there are three filter tanks 2. The filter tanks 2 and the water filtration assembly 3 are integrated into one unit. The filter tanks 2 are used to house the water filtration assembly 3.
