Abstract
Description
Technical Field
[0001] This utility model relates to the field of seawall construction technology, specifically to an ecological planting structure for concrete seawalls. Background Technology
[0002] Seawalls are protective structures built to prevent damage from tides and waves to protected areas. Currently, most seawalls are constructed by directly pouring concrete, making them rigid structures that can effectively withstand long-term wave erosion and avoid deformation. However, simple concrete seawalls cannot provide a suitable growing environment for native coastal vegetation, disrupting the biological corridors and ecological buffer zones of the land-sea transition zone and reducing biodiversity. Furthermore, because seawalls need to withstand continuous wave erosion, concrete seawalls cannot provide the necessary environment for plant growth by directly laying soil on top of them.
[0003] In existing concrete seawalls, geogrids are typically erected on the surface and filled with topsoil to facilitate the planting of vegetation. However, this method of erecting geogrids on the concrete seawall surface still exposes the topsoil to the effects of waves and rainfall, leading to rapid soil erosion and significantly impacting the growth of vegetation. Utility Model Content
[0004] This invention provides an ecological planting structure for concrete seawalls to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] An ecological planting structure for a concrete seawall includes a gravel mixture layer laid on the surface of the concrete seawall; the gravel mixture layer is formed by bonding multiple gravels together with an adhesive; a planting soil layer is laid on the gravel mixture layer, and a planting soil protective layer is laid on the planting soil layer; it also includes multiple planting holes that penetrate the planting soil protective layer and connect to the planting soil layer; ecological plants are planted in the planting holes, and the roots of the ecological plants extend through the planting soil layer into the gravel mixture layer.
[0007] Furthermore, the crushed stone concrete layer has pores between the crushed stones, and the bottom of the planting soil layer is embedded in the pores.
[0008] Furthermore, the inner wall of the planting hole is provided with water-retaining cotton, which is placed on the outside of the roots of the ecological plant.
[0009] Furthermore, the height of the top of the concrete seawall surface is higher than the height of the seawall top road, and the concrete seawall surface that extends beyond the seawall top road forms a retaining wall.
[0010] Furthermore, it also includes a crushed stone stabilization wall, which is installed at the bottom of the concrete seawall.
[0011] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0012] This invention protects both the planting soil layer and the vegetation by laying a protective layer on top of the planting soil layer. This reduces the rate of soil loss due to waves and rainfall, thus promoting the healthy growth of the vegetation. Crushed stones are bonded together with an adhesive to form a mixed layer. This mixed layer has sufficient strength and numerous pores, allowing the roots of the vegetation to directly extend into these pores. The roots further strengthen the bond between the mixed layer and the planting soil layer, enhancing the protection of the planting soil layer. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.
[0017] like Figure 1 , Figure 2 As shown, an ecological planting structure for a concrete seawall includes a gravel mixture layer 1 laid on the surface of the concrete seawall 2; the gravel mixture layer 1 is formed by bonding multiple gravels together with an adhesive; a planting soil layer 4 is laid on the gravel mixture layer 1, and a planting soil protective layer 5 is laid on the planting soil layer 4; it also includes multiple planting holes 6, which pass through the planting soil protective layer 5 and connect to the planting soil layer 4; ecological plants are planted in the planting holes 6, and the roots of the ecological plants extend through the planting soil layer 4 into the gravel mixture layer 1.
[0018] The planting soil layer 4 consists of cultivated soil; the ecological plants can be marine shrubs, marine vines, or marine grasses.
[0019] In this invention, the crushed stone mixed layer 1 is a structure composed of crushed stone and adhesive laid on the surface of the concrete seawall 2. A 5cm thick planting soil protective layer 5 is laid on top of the planting soil layer 4. The specific material of the planting soil protective layer 5 is a hardening anti-permeability agent mixed with silt and sand according to gradation standards. This hardening anti-permeability agent comprises the following raw materials in parts by weight: calcium carbonate 30-50, sodium polyacrylate 1-5, activated carbon 10-20, crack-resistant and waterproofing agent 10-20, calcium formate 5-10, redispersible latex powder 1-5, diatomaceous earth 3-8, silica gel desiccant 3-8, and calcium chloride 5-15. Preferably, the raw materials in parts by weight are: calcium carbonate 40, sodium polyacrylate 1, activated carbon 15, crack-resistant and waterproofing agent 15, calcium formate 8, redispersible latex powder 1, diatomaceous earth 5, silica gel desiccant 5, and calcium chloride 10.
[0020] This hardening and impermeable agent functions to harden the mud and sand mixture, exhibiting excellent resistance to seepage, freeze-thaw cycles, and erosion, thus ensuring long-term use. The planting soil protective layer 5 effectively isolates the planting soil layer 4 from external waves and rainfall, reducing direct erosion and slowing its loss, thus protecting it. Furthermore, the planting soil protective layer 5 can delay moisture evaporation from the planting soil layer 4 under prolonged sunlight exposure, ensuring the normal growth of the plants.
[0021] Planting holes 6 penetrate the planting soil protective layer 5 and the planting soil layer 4, and are used for planting ecological plants. The depth of planting holes 6 is 7-12cm, and the diameter of the hole opening is 5-8cm. Planting holes 6 are pre-drilled into the planting soil protective layer 5 by inserting a mold into the planting soil protective layer 5 before it solidifies. Figure 1 As shown, the bottom of the planting hole 6 penetrates the planting soil protective layer 5 and extends into the lower part of the planting soil layer 4, so that when the plants are planted in the planting hole 6, their roots can spread into the gravel mixture layer 1; or as... Figure 2 As shown, the roots penetrate the planting soil protective layer 5 and the planting soil layer 4, reaching the gravel mixture layer 1. This allows the roots of the ecological plants planted in the planting holes 6 to spread more quickly into the gravel mixture layer 1, thereby increasing the bonding force between the plants, the planting soil layer 4, and the gravel mixture layer 1. The roots also make the bond between the gravel mixture layer and the planting soil layer more stable, further increasing the protective effect on the planting soil layer. Furthermore, the roots help the plants resist the erosion of external waves, allowing them to remain in their original position even under the impact of external waves, preventing the plants from moving and thus avoiding affecting the distribution of ecological plants on the seawall surface.
[0022] like Figure 1 and Figure 2As shown, by evenly distributing multiple planting holes 6 on the planting soil protective layer 5, the plants can also be evenly distributed on the planting soil protective layer 5, i.e., the surface of the concrete seawall 2. This optimizes the distribution of the bonding force between all the plants on the entire surface of the concrete seawall 2, avoiding damage to the ecological planting structure caused by excessive local stress, and also making it more aesthetically pleasing. The multiple evenly distributed planting holes 6 allow the roots of the plants to intertwine within the gravel mixture layer 1, thereby further increasing the bonding force between the plants and helping to improve the overall erosion resistance of the plants.
[0023] Figure 1 , Figure 2 These are two embodiments, the difference being the depth to which the planting hole 6 penetrates the planting soil layer 4. Figure 2 The illustrated embodiment shows that the planting holes 6 extend into the gravel mixture layer 1, which facilitates the spread of the roots of the ecological plants into the pores of the gravel mixture layer 1, thereby enabling the bonding between the gravel mixture layer 1 and the planting soil layer 4 to occur more quickly.
[0024] Furthermore, the crushed stone in the aggregate layer has pores between the stones, and the bottom of the planting soil layer 4 is embedded in these pores. The crushed stone particle size is approximately 6-9 cm, and a polyurethane adhesive can be used as the binder. This polyurethane adhesive can be a highly environmentally friendly adhesive produced by BASF (Germany), resulting in an uneven pore structure with a porosity of approximately 48% in the aggregate layer 1. The planting soil layer 4 is laid using a pressurized spraying method, allowing some of the planting soil to be sprayed into the pores, forming a stable soil structure together with the planting soil layer 4 above the aggregate layer 1. The spraying thickness is approximately 15 cm, increasing the planting soil layer 4's resistance to wave and rain erosion.
[0025] In addition to its application on concrete seawalls 2, this invention can also be widely applied to water-adjacent structures with hardened concrete layers, such as riverbanks or water-adjacent slopes, thereby effectively optimizing the soil and water conservation capacity of the aforementioned water-adjacent structures in terms of ecological plant planting.
[0026] Furthermore, the inner wall of the planting hole 6 is provided with water-retaining cotton 7, which is placed on the outer side of the roots of the ecological plant. Figure 1 and Figure 2 After the plant is inserted into the planting hole 6, the hole is filled with water-retaining cotton 7. This ensures that the waves directly impact the cotton 7, reducing the scouring force on the planting soil layer 4 at the bottom of the hole 6 and also helping to fix the plant in place. Furthermore, the cotton 7 has absorbent and water-retaining properties, ensuring that the plant maintains sufficient humidity even without wave impact, thus ensuring its normal growth. In this embodiment, the cotton 7 is made of absorbent sponge or other soft absorbent material with a certain degree of plasticity.
[0027] Furthermore, the top of the concrete seawall 2 is higher than the height of the road on top of the seawall 9, and the concrete seawall 2 extending beyond the road on top of the seawall 9 forms a retaining wall 8. This enhances the protective effect of the concrete seawall 2 against sea waves, making it less likely for sea waves to affect the road on top of the seawall 9.
[0028] Furthermore, it also includes a gravel-stabilized wall 3, which is installed at the bottom of the concrete seawall 2. A gravel-stabilized wall 3 is provided to serve a load-bearing function at the bottom of the ecological planting structure, assisting the concrete seawall 2 in bearing the weight of the entire ecological planting structure and preventing landslides and collapses. The gravel-stabilized wall 3 seals the bottom of the structure, preventing waves from eroding the bottom of the planting soil layer 4 and further reducing the rate of soil loss.
[0029] The terms "connection" and "fixing" appearing in this utility model description can refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meaning of the above terms in this utility model should be understood according to the specific circumstances.
