Description

Technical Field

[0001] This utility model relates to the field of ecological restoration device technology, specifically an ecological restoration device for steep, smooth rock slopes. Background Technology

[0002] During the construction of ecological restoration, landscaping, and mine management projects, numerous steep rock slopes have been created. These slopes are characterized by exposed rock and severe soil erosion, hindering vegetation growth and impacting both the landscape and the risk of landslides and rockfalls. my country has invested significant human, material, and financial resources in their restoration. Currently, commonly used methods include three-dimensional vegetation netting, hydroseeding, and vegetated concrete techniques. However, these methods still face challenges such as limitations due to steep slopes, complex processes, and high maintenance costs.

[0003] Patent application number 201821675280.6 discloses a protective net and a stacked non-woven bag greening structure for steep rock slopes, including a protective net, bags, and anchors. The bags are arranged inside the protective net, and the protective net and bags are fixed to the slope by anchors. There are four anchors. The bags are composed of multiple units, which are cuboid structures and are arranged in a staggered manner in the horizontal direction. This solution ensures that the gravel does not slide down and can better protect the greening growth of shrubs and small trees. In practice, this method and structure are more convenient to construct, thereby effectively reducing the construction difficulty for construction workers.

[0004] The disadvantages of the patent solution with application number 201821675280.6 are: 1. The bag has poor durability, is easily damaged, and has poor water retention; 2. The protective net is fixed by anchor rods, and the bag is only fixed by the protective net without a separate fixing structure, resulting in poor positioning effect. When it is windy or rainy, the bag will move inside the protective net. Utility Model Content

[0005] The main purpose of this invention is to provide an ecological restoration device for steep, smooth rock slopes, in order to solve the problems of poor bag durability and water retention and poor bag positioning effect in the prior art.

[0006] To achieve the above objectives, this utility model provides an ecological restoration device for steep, smooth rock slopes, including a protective net that can be fixed on the slope and a net bag for storing planting substrate that can be set inside the protective net. The net bag includes a non-woven fabric bag and a basalt fiber mesh bag set outside the non-woven fabric bag.

[0007] Furthermore, the inside of the non-woven bag is equipped with a waterproof membrane bag.

[0008] Furthermore, the net bag is fixedly connected to a net bag fixing rod for insertion into the slope.

[0009] Furthermore, the protective netting is fixedly connected with protective netting fixing rods for insertion into the slope.

[0010] This invention improves the durability of the mesh bag by incorporating a basalt fiber mesh bag, making it less prone to damage; it also enhances the water retention of the mesh bag by incorporating a waterproof membrane bag, preventing moisture loss; and it provides a mesh bag fixing rod to individually secure the mesh bag and prevent it from moving.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 3 As shown in the embodiment of this utility model, an ecological restoration device for steep, smooth rock slopes is provided, including a protective net 1 that can be fixed on the slope, and a net bag 2 for storing planting substrate 3 that can be set inside the protective net 1. The net bag 2 includes a non-woven bag 202 and a basalt fiber mesh bag 203 set outside the non-woven bag 202. The basalt fiber mesh bag 203 has a thickness of 0.2 mm and a mesh size of 5 mm * 5 mm.

[0018] The non-woven bag 202 has a geomembrane bag 201 on the inside; the geomembrane bag 201 is made of polypropylene or polyethylene; because water will flow downwards due to gravity, the geomembrane bag 201 can be a full-coverage bag that completely wraps the planting substrate 3, or a half-coverage bag that only wraps the bottom of the planting substrate 3.

[0019] Net bag 2 is fixedly connected to net bag fixing rod 4 for insertion into the slope.

[0020] The protective net 1 is fixedly connected to a protective net fixing rod 5 for insertion into the slope.

[0021] The construction process for ecological restoration of steep, smooth rock slopes includes the following steps:

[0022] (1) Make the mesh bag 2 and connect the mesh bag 2 to the mesh bag fixing rod 4 in advance to form a whole;

[0023] (2) Drilling anchor bolt holes: The anchor bolt holes are the anchor bolt holes of the net bag fixing rod 4 and the anchor bolt holes of the protective net fixing rod 5;

[0024] (3) Install net bag 2: Insert the pre-made net bag fixing rod 4 into the anchor bolt hole to fix the net bag 2 on the slope;

[0025] (4) Install protective netting 1: Fix protective netting 1 to the surface of net bag 2 using protective netting fixing rod 5 for secondary fixation;

[0026] (5) Filling planting substrate 3: The planting substrate 3, which is mixed with seeds, organic fertilizer, plant fiber, compound fertilizer and water-retaining agent, is injected into the vegetation restoration net bag through the spraying equipment.

[0027] This utility model improves the durability of the mesh bag by setting the basalt fiber mesh bag 203, making it less prone to damage; it improves the water retention of the mesh bag by setting the impermeable membrane bag 201, making it less likely for moisture to escape; and it can fix the mesh bag individually by setting the mesh bag fixing rod 4, preventing the mesh bag from moving.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
