Description

Technical Field

[0001] This utility model relates to the field of mine ecological restoration technology, and in particular to a vegetation bag for simple revegetation of rock slopes. Background Technology

[0002] In ecological restoration projects of abandoned mines, large-scale rock pile slopes are often encountered. These slopes are typically located in areas without existing roads for large construction machinery. Furthermore, the surrounding area may contain protected forests or other ecological environments, making it impossible to construct new roads specifically for the restoration project. Therefore, how to effectively and cost-effectively revegetate rock pile slopes under these challenging conditions—where roads are inaccessible and machinery cannot reach—has become a pressing technical problem.

[0003] While existing conventional planting bags can hold plant seeds and soil, in the aforementioned special environments, the initial supply of water and nutrients relies entirely on artificial care or natural rainfall. During dry seasons or on barren slopes, the survival rate of seeds and the early growth rate cannot be guaranteed, resulting in poor revegetation effects. Utility Model Content

[0004] The purpose of this utility model is to provide a vegetation bag for simple revegetation of rocky slopes, in order to solve the technical problem that conventional vegetation bags rely on artificial maintenance or natural rainfall, and the revegetation effect is not good in dry seasons or on barren slopes.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a vegetation bag for simple revegetation of rubble slopes, wherein the vegetation bag for simple revegetation of rubble slopes comprises:

[0006] The bag body is composed of an inner bag and an outer bag connected together, and a planting chamber for containing planting soil and plant seeds is formed between the inner bag and the outer bag.

[0007] A fertilizer bag, wherein the fertilizer bag is disposed between the inner bag and the outer bag, and the fertilizer bag contains fertilizer;

[0008] A water collection bag is disposed between the inner bag and the outer bag, and the water collection bag is filled with water.

[0009] In one embodiment, both the fertilizer bag and the water collection bag are made of a slow-permeability material.

[0010] In one embodiment, the top surface of the water collection bag is provided with a slit inlet for collecting rainwater.

[0011] In one embodiment, the water collection bag has an internal support frame made of rigid material for expanding the water collection bag.

[0012] In one embodiment, the planting chamber, fertilizer bag, and water collection bag are arranged in a periodic, cyclical manner along the length of the bag body.

[0013] In one embodiment, the bag body is made of a porous mesh material such as non-woven fabric or sunshade net.

[0014] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0015] This utility model provides a simple vegetation bag for revegetating rocky slopes. Through its built-in fertilizer bag and pre-filled water collection bag, it provides a stable and continuous supply of nutrients and water for plant seeds during germination and seedling stages, solving the problem of difficult early-stage maintenance. Furthermore, the water collection bag not only stores water initially, but its slit opening at the top also effectively collects and stores natural rainfall later, providing moisture to the vegetation during drought through slow release, thus enhancing the vegetation's drought resistance. In addition, the vegetation bag has a simple structure; all materials can be prefabricated and filled off-site, and after transportation to the site, it can be easily deployed on the target slope by manpower or other simple methods, making it particularly suitable for areas inaccessible by machinery. Finally, the fertilizer bag and water collection bag use slow-permeability materials to ensure the slow and even release of water and fertilizer, avoiding nutrient loss and rapid water evaporation, providing a long-term stable growth environment for the vegetation.

[0025] Please see Figures 1 to 2 This application provides a vegetation bag for simple revegetation of rocky slopes. The vegetation bag includes a main body 1, which is composed of an outer bag 12 and an inner bag 11. The inner and outer bags 12 are connected to form multiple semi-circular vegetation chambers 13. Before installation, the vegetation chambers 13 are filled with planting soil and plant seeds suitable for the local environment. The main body 1 can be made of porous mesh materials such as non-woven fabric or shade net to facilitate root penetration and gas exchange.

[0026] The core of this invention lies in the fact that, between the inner and outer layers of the bag body 12, in addition to the planting chamber 13, fertilizer bags 2 and water collection bags 3 are alternately arranged. For example, on a 5-meter-long planting bag, a planting chamber 13 is set every 50 centimeters, and between two planting chambers 13, a fertilizer bag 2 and a water collection bag 3 are alternately inserted. This arrangement ensures that any planting chamber 13 is adjacent to a fertilizer bag 2 and a water collection bag 3, thereby efficiently acquiring water and fertilizer resources.

[0027] Fertilizer bag 2 is an independent chamber pre-filled with solid or granular fertilizers needed for plant growth. The bag body of fertilizer bag 2 is made of a slow-permeable material, allowing the nutrients inside to slowly seep out and integrate into the soil of the adjacent plant chamber 13, providing long-lasting nutrients for the plants.

[0028] Water collection bag 3 (attached) Figure 1 The water collection bag (labeled as "collection bag") is also an independent chamber located between the inner and outer bags 12. Before use, a certain amount of water can be injected into it to ensure the early survival of the vegetation. The water collection bag 3 is also made of a slow-permeable material, and water will slowly seep out to moisten the soil. More importantly, the top of the water collection bag 3 (i.e., the side closest to the outer bag 12) has a slit entrance 31 for collecting and storing rainwater during rainfall. Specifically, the width of the slit is 1-2mm, which ensures that external rainwater can quickly flow into the water collection bag 3 during rainfall, while avoiding the slit entrance 31 being too large, which would cause the water inside the water collection bag 3 to evaporate too quickly. Alternatively, the top can be designed as an overlapping "valve-type" opening, that is, using the elasticity of the material itself, it can close to reduce evaporation when there is no rain, and be pushed open by the gravity of the water when rainwater is collected, allowing the water to flow into the bag.

[0029] Specifically, the walls of fertilizer bags 2 and water collection bags 3 can be made of non-woven fabric with a specific weight and density, or biodegradable polymer porous membranes. The pore size of these materials is designed so that the solution formed by the dissolution of water and fertilizer inside the bags can permeate into the soil of the plant growth chamber 13 at a slow and relatively constant rate. The permeation cycle can be designed to last from several weeks to several months to match the growth needs of the plants throughout their entire seedling stage.

[0030] The outer bag 12 of the main bag 1 can be made of UV-resistant, high-tensile-strength polyethylene (PE) or polypropylene (PP) shade netting to resist harsh outdoor environments. The inner bag 11 can be made of hydrophilic non-woven fabric, which can effectively wrap and fix the planting soil while allowing plant roots to easily penetrate. The inner and outer layers are connected together by stitching or heat fusion.

[0031] To prevent the water collection bag 3 from collapsing after water loss or under pressure, a support frame 4 made of rigid material is installed inside. This support frame 4 can effectively support the water collection bag 3, maintain its internal space, and ensure the effective functioning of its rainwater collection and storage functions.

[0032] The support frame 4 can be designed as a lightweight, strong semi-circular or arched frame, made of materials such as polypropylene (PP), high-density polyethylene (HDPE), or rust-proofed fine steel wire. This frame is fixed to the inner wall of the water collection bag 3, effectively supporting the flexible material and creating a stable water storage space.

[0033] In use, workers simply need to manually transport these prefabricated planting bags to the target rock slope and properly place them. In the early stages, water and nutrients are automatically supplied by the water collection bag 3 and fertilizer bag 2 through slow release. In the later stages, the rainwater collected by the water collection bag 3 can help the slope survive the drought period, which greatly simplifies the construction and maintenance process and successfully solves the problem of slope revegetation in areas where machinery cannot reach.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
