For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figures 1 to 4 The embodiment of the present application provides a rigid horizontal grid reinforced vegetation mat, comprising a plurality of vegetation substrate bags 4, a polyethylene net 2, a plurality of mortar bags 3, and a thin cotton layer 1. The polyethylene net 2 is arranged on the surface of the thin cotton layer 1; the mortar bag 3 is arranged transversely in the polyethylene net 2; and the vegetation substrate bag 4 is arranged transversely in the polyethylene net 2 between adjacent mortar bags 3.

[0026] Since the mortar bag 3 is plastic before solidification, it can be tightly adhered to the unevenness of the slope surface 6, and after solidification, it forms a strong rigid horizontal grid, which plays a role in reinforcing the slope surface 6. The vegetation substrate bag 4 is connected to the mortar bag 3 through the polyethylene net 2, providing a stable foundation for the growth of plants, and at the same time, together with the mortar bag 3, it plays a role in alleviating surface runoff caused by rainfall and inhibiting soil erosion.

[0027] Moreover, the thin cotton layer 1 at the bottom plays multiple important roles, including: 1. Soil conservation and plant support: The thin cotton layer 1 provides a stable growth environment for plants, can keep the soil from being lost, and provide support for the plant roots. This helps plants grow and take root on unstable surfaces such as slopes 6. 2. Water conservation: The thin cotton layer 1 usually has good water retention performance, can store water and slowly release it to plants, which helps to keep the soil moist and provide a stable water supply for plants. 3. Temperature regulation: The thin cotton layer 1 can regulate soil temperature and reduce the impact of extreme temperatures on plant roots. In winter, it can prevent the soil from overcooling; in summer, it can reduce soil temperature and reduce the negative impact of high temperature on plant growth. 4. Soil improvement: The thin cotton layer 1 can be mixed with soil to improve the physical properties of the soil, such as increasing the air permeability and water retention of the soil, improving soil fertility, and providing better growth conditions for plants. 5. Biodegradation and environmental protection: If the thin cotton layer 1 is made of biodegradable materials, it can decompose naturally after completing its mission and will not cause long-term pollution to the environment. This helps achieve the goal of eco-friendliness and sustainable development. 6. Fixing the vegetation substrate bags 4: The thin cotton layer 1 can be used as a base layer to fix the vegetation substrate bags 4 on the slope 6 to prevent them from shifting or sliding, ensuring that the plants can grow stably.

[0028] In summary, the thin cotton layer 1 plays an important role in the rigid horizontal grid reinforcement vegetation mat. It not only provides a good growth environment for plants, but also helps to maintain the stability of the slope 6 and improve soil conditions.

[0029] The polyethylene net 2 has a high tensile strength due to its mesh structure, so as to more firmly connect and fix the vegetation substrate bag 4 to the mortar bag 3, thereby improving the overall stability of the rigid horizontal grid reinforcement vegetation mat. In addition, the mesh structure has good permeability and will not hinder the root breathing of the vegetation on the slope 6, which is conducive to the growth and development of the vegetation.

[0030] In one embodiment, the mortar bag 3 includes a bag body 31 (a plurality of small holes are provided on the bag body 31 to facilitate subsequent soaking of the mortar bag 3 and hardening of the mortar bag 3), reinforcing fibers 33, and mortar 32 (the mortar 32 is mainly a mixture of sandstone and cement). The bag body 31 is in a long strip shape; the mortar 32 is arranged and filled in the bag body 31; the reinforcing fibers 33 are arranged inside the bag body 31 along the length direction of the bag body 31, and the reinforcing fibers 33 are connected to the bag body 31.

[0031] By arranging the reinforcing fibers 33 in the mortar bag 3, the strength of the mortar bag 3 can be effectively improved and the probability of cracking can be reduced. The reinforcing fibers 33 are arranged along the length direction of the bag body 31 and connected to the bag body 31 to form an integrated structure. This structure enables the mortar bag 3 to better disperse stress when subjected to external force, thereby improving the tensile strength and crack resistance of the mortar bag 3.

[0032] In one embodiment, the reinforcing fibers 33 are evenly distributed in the bag body 31. By evenly distributing the reinforcing fibers 33 in the bag body 31, the reinforcing effect of the reinforcing fibers 33 can be evenly applied to the mortar bag 3, further improving the tensile strength and crack resistance of the mortar bag 3.

[0033] In one embodiment, a drying bag 5 is further included, and the drying bag 5 is transversely arranged in the polyethylene net 2 near the mortar bag 3. By arranging the drying bag 5 in the polyethylene net 2 near the mortar bag 3, the mortar bag 3 can be prevented from being damaged by moisture during storage and transportation. The drying bag 5 is filled with a desiccant, which can absorb and store moisture and keep the mortar bag 3 dry. This can not only extend the service life of the mortar bag 3, but also ensure that the mortar bag 3 has a good curing effect during laying.

[0034] Specifically, the desiccant can be calcium chloride desiccant, which is an efficient and environmentally friendly desiccant that can quickly absorb moisture in the air. It has the characteristics of large moisture absorption capacity, fast moisture absorption speed, and non-corrosiveness. And because calcium chloride is easily soluble in water after it meets water, when the rigid horizontal grid reinforcement vegetation mat is laid, when it rains, the calcium chloride desiccant in the drying bag 5 will dissolve in the rainwater, and then can be used as fertilizer to improve the soil of the slope 6, so as to facilitate the rapid growth of vegetation on the slope 6 and accelerate the greening speed of the slope 6.

[0035] In one embodiment, the thin cotton layer 1 contains seeds and soil improvement materials. By placing seeds and soil improvement materials (such as fertilizers, etc.) in the thin cotton layer 1, the soil environment of the slope 6 can be improved and the growth of plants can be promoted. The seeds can quickly germinate and grow into plants after the mortar bag 3 is cured, thereby increasing the vegetation coverage of the slope 6 and improving the ability of the slope 6 to resist soil erosion. The soil improvement materials can improve the soil structure, increase soil fertility, and provide better conditions for plant growth.

[0036] In one embodiment, the distance between adjacent vegetation substrate bags 4 and mortar bags 3 is the same. Placing the vegetation substrate bags 4 and mortar bags 3 at equal distances can form a small step effect, which helps to mitigate surface runoff caused by rainfall, slow down the water flow rate, and thus reduce the risk of soil erosion. At the same time, this structure can also provide more space for plant growth, which is conducive to the expansion and growth of plant roots.

[0037] Another object of the present invention is to provide an application method of a rigid horizontal grid reinforced vegetation mat, which uses the rigid horizontal grid reinforced vegetation mat in any one of the above embodiments. The application method of the rigid horizontal grid reinforced vegetation mat includes the following steps: S1. Laying a rigid horizontal grid reinforced vegetation mat, laying the rigid horizontal grid reinforced vegetation mat on the slope surface 6, and pressing the mortar bag 3 so that the mortar bag 3 fits tightly on the undulating slope surface 6.

[0038] During the laying process, it should be ensured that the mortar bag 3 is closely attached to the undulating slope 6 to form a strong rigid horizontal grid. The vegetation substrate bag 4 is connected to the mortar bag 3 through the polyethylene net 2 to provide a foundation for the growth of plants.

[0039] S2. Fix the rigid horizontal grid to reinforce the vegetation mat, and use the anchor bolt 7 to fix the mortar bag 3 to the slope 6. When fixing, one end of the anchor bolt 7 passes through the mortar bag 3 and is inserted into the inside of the slope 6.

[0040] Specifically, one end of the anchor bolt 7 passes through the mortar bag 3 and is inserted into the slope surface 6, and the mortar bag 3 is tightly fixed on the slope surface 6 by the tension of the anchor bolt 7. In order to prevent the anchor bolt 7 from slipping off the slope surface 6 or the mortar bag 3, a plurality of anti-slip rings can be provided in an annular manner on the surface of the anchor bolt 7 to enhance the connection firmness between the anchor bolt 7 and the mortar bag 3 and the slope surface 6.

[0041] S3, the mortar bag 3 is solidified, and the mortar bag 3 is soaked by natural rainfall or artificial watering, so that the mortar 32 in the mortar bag 3 solidifies after contacting water. The solidified mortar bag 3 forms a strong and rigid horizontal grid, which can effectively resist the erosion of external natural forces, such as rain erosion and wind erosion, thereby protecting the slope 6.

[0042] In addition, when laying the rigid horizontal grid reinforcement vegetation mat, the mortar bag 3 is tightly fixed to the slope 6 by using the anchor bolts 7, and the mortar bag 3 will press the thin cotton layer 1 and the polyethylene net 2 at the bottom to the slope 6. In step S3, when the mortar bag 3 is soaked and solidified by natural rainfall or artificial sprinkling, a small amount of slurry (a mixture of cement, fine sand, water, etc.) in the mortar bag 3 will seep out of the mortar bag 3, and the seeped slurry will flow into the compressed thin cotton layer 1 and the polyethylene net 2 under the mortar bag 3. After the seeped slurry is solidified, the solidified slurry will block the mesh holes of the thin cotton layer 1 and the polyethylene net 2 in the compressed area of ​​the mortar bag 3, forming a conical water storage tank 8 (such as Figure 4 As shown), the rainwater will be stored in the water tank 8. In the dry season with little rain, the rainwater in the water tank 8 can be infiltrated by the thin cotton layer 1 on the side and the polyethylene net 2 under the capillary action to irrigate the vegetation on the slope 6, thereby alleviating the phenomenon that the vegetation on the slope 6 withers due to lack of water in the dry season with little rain.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
