Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration, and in particular to a concrete block for promoting the recovery of submerged plants and coordinating the inhabitation of benthic animals. Background Art

[0002] Submerged plants refer to large aquatic plants that live entirely below the water layer. Their roots are sometimes underdeveloped or degenerate, so their colonization is greatly affected by wind and waves or the fluidity of lake sediments. For example, in lakes with strong winds and waves, the sediment at the bottom of the lake has strong fluidity due to the disturbance of wind and waves, making it difficult for submerged plants to colonize smoothly.

[0003] The traditional improvement method is to lay wave-breaking facilities on the water surface to reduce the mobility of the bottom mud. Although this method can reduce the impact of wind and waves to a certain extent, these measures often lead to the division of the water surface, affecting the overall landscape effect, and as the water surface division decreases, submerged plants may gradually die.

[0004] Therefore, there is an urgent need for a device used at the bottom of a water body that can both reduce the mobility of bottom mud and promote the recovery of submerged plants. Summary of the invention

[0005] The present invention can solve the above problems existing in the prior art by providing a concrete block which promotes the recovery of submerged plants and cooperates with the inhabitation of benthic animals.

[0011] In a preferred embodiment of the present invention, the notch is located at the bottom of the side of the hollow cylinder.

[0012] In a preferred embodiment of the present invention, the top of the notch is an arc structure.

[0013] In a preferred embodiment of the present invention, the height of the concrete block is 15 cm.

[0014] In a preferred embodiment of the present invention, the thickness of the concrete block is 2 cm.

[0016] In a preferred embodiment of the present invention, the number of the hollow holes is the same as the number of sides of the regular polygonal structure.

[0017] In a preferred embodiment of the present invention, the method for restoring submerged plants is:

[0018] The above concrete blocks are tightly arranged at the bottom of the target lake with the bottom facing downward and the sides tightly attached. After a period of time, the roots of submerged plants are established, and the plants extend from the grooves on the sides of the concrete blocks and the hollow holes on the top surface to resume growth.

[0019] The beneficial effects of the present invention are as follows: the present invention promotes the recovery of submerged plants and the inhabitation of benthic animals in the concrete blocks, and through the structural design of the concrete blocks, effectively reduces the impact of wind and waves on the lake bottom mud, promotes the re-colonization of the roots of submerged plants, and can smoothly grow and spread from the bottom of the concrete blocks, effectively promoting the recovery of submerged plants, with good effects and strong practicality.

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] See also Figure 1 and Figure 2 , the embodiment of the present invention includes:

[0026] Example 1

[0027] The invention discloses a concrete block for promoting the recovery of submerged plants. The concrete block is prepared by adopting environmentally friendly corrosion-resistant concrete, thereby ensuring that the concrete block has excellent durability and stability in a water environment.

[0028] Specifically, the concrete block 10 is a hollow cylinder, and the top surface of the hollow cylinder is a regular polygonal structure, such as a regular quadrilateral, a regular pentagon, a regular hexagon or a regular octagon. In this embodiment, a regular hexagon is used as an example. The top surface of the concrete block 10 has hollow holes 11 with the same number of sides as the top surface, for the submerged plants 20 to extend out.

[0029] Specifically, the sizes of the hollow holes are the same, and the wall thickness between adjacent hollow holes 11 is equal to the wall thickness of the concrete block 10 , so that the size of the hollow holes is maximized to ensure that the submerged plants 20 can extend from the hollow holes 11 .

[0030] The bottom surface of the concrete block 10 is an open structure, and the submerged plants are blocked in the open area of ​​the concrete to prevent them from being affected by the flowing bottom mud, so that their roots can be successfully planted and resume growth, that is, a root planting area is provided for the submerged plants.

[0031] Each side of the concrete block 10 is provided with a notch 12. Specifically, the notch is located below the side, and its height is 1 / 5 to 1 / 2 of the height of the concrete block, and its width is 1 / 5 to 1 / 3 of the width of the side of the hollow cylinder.

[0032] The interior of the concrete block is hollow, making it light and easy to install underwater, and providing space for submerged plants to grow. The design of the notches and notch sizes on the side can ensure that the intensity of water flow at the bottom of the lake is reduced, reducing the fluidity of the bottom mud, while forming pores and channels inside the concrete block to facilitate water flow.

[0033] Specifically, the opening end of the slot 12 is downward, and the upward end is an arc structure, which facilitates the submerged plants 20 to spread smoothly through these slots during growth, thereby effectively supporting the growth and spread of submerged plants, ensuring that the vegetation can form a stable plant belt at the bottom of the lake, and at the same time providing a suitable habitat for benthic animals, thereby promoting the healthy development of the aquatic ecosystem.

[0034] In this embodiment, the height of the concrete block 10 is 15 cm, the thickness, i.e., the wall thickness, is 2 cm, the side length of the regular hexagon on the top surface is 15 cm, and the height of the notch on the side surface is 3 cm and the width is 5 cm. The above-mentioned size design facilitates the transportation, installation and splicing of the concrete blocks, helps to reduce the construction difficulty, improve the construction efficiency, and reduce the construction cost.

[0035] The method of using the above concrete blocks to promote the restoration of submerged plants is:

[0036] Select lakes with larger winds and waves as target lakes for submerged plant restoration;

[0037] A plurality of concrete blocks are closely arranged with their bottoms facing downward and their sides closely attached to each other, and are densely laid on the bottom of the target lake, so as to prevent the bottom mud of the lake from flowing due to wind and waves, and to cover the submerged plants in the internal cavity of the concrete blocks;

[0038] After a period of time, the roots of the submerged plants are replanted, and the plants extend from the notches on the sides of the concrete blocks and the hollow areas on the upper surfaces thereof during their growth, and resume their growth.

[0039] The above-mentioned concrete blocks are used to promote the restoration of submerged plants. Not only is the restoration effect of submerged plants good, but it also does not affect the water surface landscape and there is no separation on the water surface. In addition, concrete blocks can also provide a suitable habitat for benthic animals and increase the diversity of the aquatic ecosystem. Benthic animals can control the reproduction of algae by eating algae, organic debris, etc., prevent eutrophication of water bodies, protect water quality and the health of the ecosystem, and maintain and enhance the biodiversity of the lake ecosystem.
