Description

Technical Field

[0001] The utility model relates to the technical field of slope protection, in particular to a basalt fiber three-dimensional net suitable for slope protection. Background Art

[0002] my country has built a large number of technical facilities in water conservancy projects, transportation hubs, information infrastructure, etc., but this has inevitably caused difficult-to-eliminate disturbances to the natural environment and landforms. For example, beside the roadbed, along the river bank, and at the mine pit, the slopes are damaged due to changes in the terrain, resulting in new exposed slopes. These exposed slopes are very loose without the well-developed vegetation and stable root systems, and are very likely to collapse in a relatively concentrated precipitation environment, destroying existing infrastructure projects and endangering personnel safety. Therefore, after excavating the mountain or river bank, construction personnel often take measures such as hanging nets and spraying soil to plant grass on the slopes, so that vegetation can grow quickly on the barren slope surface, strengthen the slope soil, and resist water damage such as rainfall.

[0003] The main body of the existing slope soil spraying net is made of metal wire or polymer plastic. The metal net has a large deadweight, which imposes an additional load burden on the unstable slope. It is also not corrosion-resistant. Often, the vegetation roots fail to grow to maturity, and corrosion fractures occur, making it impossible to continue to disperse the load, resulting in large-scale landslides when the rainy season arrives. The polymer plastic net is difficult to degrade, which is contrary to the environmental protection original intention of edge greening. In addition, the overall toughness of the plastic material is insufficient, and the soil is easily compacted after spraying, making it difficult for plant roots to climb, thereby reducing the soil fixation effect. In view of the above-mentioned technical status of the soil spraying net, the industry urgently needs to develop a new type of net that is corrosion-resistant, environmentally friendly, has high structural toughness, is light in weight, and highly permeable, to improve the technical implementation effect of soil spraying and grass planting.

[0042] Specifically, the specific operation process of the utility model is as follows:

[0043] 1. After determining the slopes that need to be protected and regreened, carefully level the slope surface, remove protruding parts and sharp edges, and fill in the sunken and low-lying parts to ensure that the three-dimensional net fits the slope surface;

[0044] 2. Use small machines such as excavators to cover the slope with base planting soil, with a thickness of about 10 to 15 cm. Humus soil is preferred, and then evenly spread organic fertilizer at a rate of 50 to 75 kg / 1000 m2, and sprinkle water in small amounts and multiple times to create an organic environment for the grass seeds to grow downwards;

[0045] 3. At a position 1m away from the top of the slope, use drilling equipment to drill 5m downward at an angle of 60° every 3m horizontally. After the hole is formed, basalt fiber composite anchor bar and grouting pipe are implanted to the bottom of the hole.

During the grouting process, the grouting pipe is slowly pulled out. After the reinforcement is implanted, wait for the cement slurry to initially set;

[0046] 4. Tie the basalt fiber composite three-dimensional net to the basalt fiber composite anchoring bars planted on the top of the slope, and lay it along the slope from top to bottom. The three-dimensional structure of the growth chamber faces outward, and the three-dimensional net should be as close to the slope as possible to prevent it from being suspended in the air. At the same time, the three-dimensional net should be kept flat without wrinkles;

[0047] 5. Install galvanized expansion anchor soil nails on the slope surface at a spacing of 2m in the horizontal and vertical directions, put the main reinforcement of basalt fiber twisted wire into the wire fixing groove, and then hammer in the galvanized expansion anchor soil nails along the vertical slope until the wire fixing groove contacts the soil, and then hammer in 4 expansion secondary nails in sequence until the limit block is stuck to fully anchor;

[0048] 6. Use a hydraulic sprayer to spray the foreign soil mixed with grass seeds evenly onto the three-dimensional net. The moisture content of the foreign soil should be in the range of 40% to 50%, and the spraying amount should be such that the foreign soil is covered and does not fall off.

[0049] 7. Before the vegetation seedlings reach 3 cm, they need to be watered once a day using a water truck. Watering should be done between 11:00 and 16:00 to keep the slope moist and suitable for vegetation growth.

[0050] The utility model proposes a basalt fiber three-dimensional net suitable for slope protection, which uses basalt fiber twisted lines of different specifications to form a three-dimensional net structure for foreign soil adhesion and vegetation climbing, and uses basalt fiber composite bars to plant bars to reinforce the slope itself, and disperse and carry the weight of foreign soil and vegetation. While providing a stable growth space and root climbing environment for slope vegetation, it greatly improves the environmental protection of construction materials, provides more reliable bearing capacity dispersion and support, reduces the load of foreign soil, moisture, and net on the slope, reduces the risk of secondary landslides in the slope during concentrated precipitation, and improves the safety of infrastructure and personnel under the slope.
