Description

Technical Field

[0001] This utility model relates to the field of ecological restoration of steep slopes, specifically to a hidden grid hanging basket ecological restoration and greening device for steep rock walls, which is mainly used for ecological restoration and management of relatively steep slopes such as mines, quarries, and both sides of high-grade highways. Background Technology

[0002] Steep slopes typically have the following characteristics, making natural ecological restoration and revegetation difficult:

[0003] Steep slopes are mainly caused by human engineering activities, such as open-pit mining, road construction, and building construction. These steep slopes not only disrupt the original ecological balance but also pose serious risks of geological disasters.

[0004] Due to the unique characteristics of steep rock slopes, the restoration of the ecosystem in the natural environment is a very long process.

[0005] The plant lacks the soil, water, and nutrients necessary for its growth.

[0006] From an ecological perspective, vegetation destruction on steep slopes leads to severe soil erosion, decreased soil fertility, and reduced biodiversity. Ecological restoration and afforestation can rebuild vegetation communities, restore ecosystem functions, conserve water and soil, and improve the ecological environment.

[0007] The traditional method for treating steep slopes is slope cutting, which involves leveling the slope from top to bottom in a stepped manner, followed by platforming and slope greening. Due to site limitations and unregulated mining, this method presents certain construction difficulties, involves a large amount of work, a long construction period, and high costs, while also further damaging the ecological environment.

[0008] Currently, vegetation restoration on steep slopes typically employs the netting and hydroseeding method. Netting and hydroseeding offer good protection and enhance slope stability; they also provide excellent greening effects and enable rapid slope afforestation; the use of mechanized construction increases efficiency and reduces the risks and difficulties of manual climbing operations; however, construction requires specialized equipment and technicians, resulting in high costs; the hydroseeded vegetation is relatively fragile in its initial growth stage, requiring regular watering, fertilization, pruning, and pest and disease control, leading to high maintenance costs and a long maintenance period; and it is susceptible to large-scale vegetation loss due to rainfall and slope morphology, making repairs difficult.

[0009] Therefore, those skilled in the art have provided an ecological restoration and greening device for steep rock walls with hidden grid hanging baskets to solve the problems mentioned in the background art. Summary of the Invention

[0010] To solve the above-mentioned technical problems, this utility model provides:

[0011] A hidden grid hanging basket ecological restoration and greening device for steep rock walls. This utility model integrates the hanging basket, anchor rods, galvanized wire mesh, and ecological bags into a single unit. The hidden grid hanging basket is prefabricated in a factory. The installation of the hanging basket is a U-shaped structure composed of steel reinforcement sleeves and sleeve ribs, with one side of the basket tightly attached to the rock wall. The hanging basket is fixed to the rock wall by anchor rods. Galvanized wire mesh is laid inside the hanging basket. Vertical ecological bags are placed inside the hanging basket for greening, and the ecological bags are filled with specially formulated nutrient soil made of polypropylene (PP) fiber material. The economic benefits of this utility model are: the hidden grid hanging basket is prefabricated in a factory, the greening device is simple, the construction process is simple, the ecological restoration cost is low, the construction speed is fast, the greening effect is quick, and the ecological environment is further rapidly restored.

[0012] To achieve the above objectives, this utility model provides an ecological restoration and greening device for steep rock walls using a hidden grid hanging basket, which works as follows:

[0013] (1) After the slope is cleared, the slope surface is flat and there is no reverse slope. There is no floating debris, weeds, or other debris on the slope surface. After the slope surface is cleared, a safety suspended basket is used for construction.

[0014] (2) Anchor Bolts: The anchor bolt hole positions are pre-arranged, using HRB400Ф18 threaded steel. The anchor bolts are arranged in a triangular pattern to ensure the stability of the hidden grid hanging basket, with one main anchor and two auxiliary anchor bolts, perpendicular to the rock wall. The main anchor bolt provides tension, located at 2 / 3 of the height of the hidden grid hanging basket, with a length of 1.3m and an anchoring depth of 1.0m. The anchor bolts protrude 0.3m above the slope surface and bend upwards 0.1m at a width of 0.2m, with the angle consistent with the slope gradient. The auxiliary anchor bolts provide support and stability, with a length of 0.6m and an anchoring depth of 0.3m. The anchor bolts protrude 0.3m above the slope surface and bend upwards 0.1m, with the angle consistent with the slope gradient. Anchor bolts should be lengthened in areas where the rock mass is broken, loose, or recessed. Before use, the anchor bolts should be derusted and appropriate anti-rust treatment measures should be taken. Dry drilling using a pneumatic rock drill or water jet drilling is employed. After drilling, high-pressure air jetting must be used to ensure that rock powder and sediment inside the borehole are thoroughly washed away. Anchor bolts are then fixed by direct insertion after drilling, and the anchor bolt holes are anchored with M30 cement grout with a water-cement ratio of 1:1.

[0015] (3) Hidden-cell hanging basket: It is a U-shaped structure composed of steel reinforcement sleeves and sleeve reinforcement bars. It consists of 3 rows of horizontal sleeves, 4 columns of vertical U-shaped reinforcement bars, 1 horizontal U-shaped reinforcement bar in the middle, 2 horizontal reinforcement bars at the bottom, and 2 hanging reinforcement bars. The sleeves are on the outside. It is made of HRB300Ф10 steel bars with a specification of 0.4m*0.2m*0.3m and is a rectangular open steel reinforcement cage. The length of one sleeve is 0.88mm, the length of one vertical U-shaped reinforcement bar is 0.62m, the length of one horizontal U-shaped reinforcement bar in the middle is 0.72m, and the length of one horizontal reinforcement bar at the bottom is 0.4m. The total length of steel reinforcement required for one hanging basket is 7.56m. The horizontal sleeves, vertical U-shaped reinforcement bars, horizontal U-shaped reinforcement bars, bottom horizontal reinforcement bars, and hanging reinforcement bars are connected by welding. The steel reinforcement cage hole spacing is 100mm*100mm. The vertical inclination of the hanging basket is consistent with the slope. The steel reinforcement cage of the hanging basket is prefabricated by welding in the factory and directly installed on site. It is connected to the anchor rod by binding. The steel reinforcement cage of the hidden-compartment hanging basket must be rust-proofed before it can be used.

[0016] (4) Hanging rods: HRB300Ф10 rods are used to form a figure-eight shape. The upper end is connected to the main anchor rod by binding. The lower half is connected to the sleeve rod by double-sided welding on both sides. The welding length is not less than 5D (50mm). One hanging rod is 0.46m long. Two hanging rods are needed for one hanging basket. The length is 0.92m. The steel bars must be rust-proofed before they can be used.

[0017] (5) Galvanized wire mesh: 12# galvanized plastic-coated wire mesh with a mesh size of 5cm*5cm is used. It is laid inside the steel cage and tied to the steel cage with galvanized wire.

[0018] (6) Vertical Ecological Bags: Vertical ecological bags serve as the main body of the hidden-grid hanging basket greening system. The ecological bags are filled with nutrient soil and greening plant seeds. Two ecological bags with a diameter of 200mm and a height of 300mm are placed in the hanging basket. Polypropylene (PP) fiber rods are used to fill the specially made nutrient soil, which contains a water-retaining agent. The soil is connected to the steel cage by binding.

[0019] (7) Greening: Fill the ecological bags with nutrient soil and place seeds of plants such as alfalfa, purple locust, alfalfa, crown lily, wildflower combination, ryegrass, and buffalo grass.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] The concealed-grid hanging basket is prefabricated in the factory, making the greening device simple, the construction process straightforward, the ecological restoration cost low, the construction speed fast, and the greening effect quick, resulting in rapid ecological restoration. It also reduces the risks and difficulties of manual climbing operations. This solves the current problems of high cost and long timeframes for greening steep slopes, while also providing some protection against geological hazards. Attached Figure Description

[0029] The construction process of this utility model includes the following sequential steps:

[0030] The construction sequence of the rock face hanging basket strip method is as follows: sloping surface hole layout → installation of anchor bolts → installation of hidden grid hanging baskets → laying galvanized plastic-coated wire mesh inside → placing two vertical ecological bags in the hanging baskets → planting shrubs and climbing plants.

[0031] (1) First, carry out hazard removal work on the steep slope and remove unstable rocks.

[0032] (2) A pneumatic rock drill with a diameter of 40mm was used perpendicular to the rock surface, followed by an HRB400 drill with a diameter of 18mm. The anchor bolts were arranged in a triangular pattern to ensure the stability of the hanging basket, with one main bolt and two auxiliary bolts, and the anchor bolts were perpendicular to the rock wall. The main anchor bolt provided tension and was located at 2 / 3 of the hanging basket height. The main anchor bolt was 1.30m long and 1.0m deep into the rock. The bolts were exposed 0.3m above the slope and bent upwards 0.1m at a width of 0.2m, with the angle consistent with the slope. The auxiliary anchor bolts provided support and stability. The anchor bolts were 0.6m long and 0.3m deep into the rock. The bolts were exposed 0.3m above the slope and bent upwards 0.1m, with the angle consistent with the slope. The anchor bolts were fixed by drilling and then inserting them directly into the holes. The anchor bolt holes were anchored with M30 cement mortar with a water-cement ratio of 1:1.

[0033] (3) Place the hidden grid hanging basket on the anchor rod along the slope and attach it tightly to the rock wall. Fix it to the anchor rod by binding. The specifications of the hanging basket are 0.4*0.2*0.3m. The hidden grid hanging basket is composed of a sleeve, U-shaped reinforcement, transverse reinforcement and hanging reinforcement. It is made of HRB300Ф10mm with a mesh size of 100*100mm. The hidden grid hanging basket is prefabricated in the welding factory and installed on site. A crane is used for installation on the slope. The steel bars need to be rust-proofed.
