Description

Technical Field

[0001] The invention relates to the technical field of slope protection vegetation bags, and in particular to a slope ecological protection film vegetation bag and a construction method. Background Art

[0002] With the rapid development of my country's economy, the pace of highway construction is getting faster and faster. In recent years, the total mileage of my country's highways has continued to grow, the number of cars has continued to increase, and the position of highways in the comprehensive transportation system of the national economy has become more and more important. Along with the rapid development of highways, a large amount of mountain excavation is often carried out in the construction of highways, railways and other infrastructure, destroying the original vegetation topsoil layer and native plant communities, causing a large amount of secondary bare land and serious soil erosion and land desertification. As a result, a large amount of broken and weathered rock slope protection problems are often encountered during the construction process. Highway pollution and the impact of highways on the surrounding environment have also emerged in large numbers.

[0003] Vegetation bags are one of the important materials for ecological restoration and reconstruction of rock slopes on highways and open-pit mines. They are mainly composed of culture soil, plant seeds and degradable packaging bags. The construction process of this technology mainly includes the preparation of vegetation bags, substrate preparation, bagging, transportation to the working face, stacking and fixing of vegetation bags and maintenance. Since the ecological protection technology of vegetation bags has the advantages of simple construction process, good reclamation effect, convenient transportation and low cost, biological protection of rock slopes on highways and open-pit mines is an effective way to green the highways. It is not only conducive to greening and beautifying the environment, but also can effectively prevent soil erosion on the slope, and play a role in protecting and stabilizing the slope.

[0004] However, there are some problems such as the use of multiple nutrient substrates in existing vegetation bags, easy dislocation and sliding, poor anti-scouring ability, inconsistent vegetation density, and being unfavorable to the growth of ecological communities. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a slope ecological protection film vegetation bag and a construction method to solve the problems of the existing vegetation bags using a lot of nutrient substrates, easy dislocation and sliding, poor anti-scouring ability, and inconsistent vegetation density.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows.

[0007] A slope ecological protection film vegetation bag and a construction method, comprising an anchor rod, a film vegetation bag, a connecting lock, a wire mesh, a locking soil nail, and a connecting plate nail; the anchor rod is inserted into the soil or rock mass and connected to the film vegetation bag and the wire mesh, the connecting lock is connected to the film vegetation bag, the connecting lock and the wire mesh are connected to the locking soil nail, the locking soil nail and the connecting plate nail are used to connect the film vegetation bags, and the locking soil nail and the anchor rod work together to fix the film vegetation bag.

[0008] Furthermore, the film vegetation bag is divided into 7 layers, which are, from top to bottom, the surface polyethylene ecological honeycomb net, the upper non-woven cotton fiber cloth, the nutrient matrix soil layer, the thickened non-woven cotton fiber cloth, the ordinary soil layer containing fertilizer, the lower non-woven cotton fiber cloth, and the bottom polyethylene ecological honeycomb net.

[0009] Furthermore, the thickness of the nutrient matrix soil layer is 3 to 5 cm, and the thickness of the common soil layer containing fertilizer is 5 to 8 cm. The thickened non-woven cotton fiber cloth is a barrier between the nutrient matrix soil layer and the common soil layer containing fertilizer.

[0010] Furthermore, the thickened non-woven cotton fiber cloth, the nutrient matrix soil layer, and the upper layer of non-woven cotton fiber cloth are sewn into two rows by transversely pressing the film vegetation bag through professional production equipment.

[0011] Furthermore, after the film vegetation bags are sewn into two rows, the nutrient soil layer will be squeezed to both sides, and a valley will be formed at the middle seam of the film vegetation bag and the connection between the single film vegetation bags, and rainwater on the top of the slope can flow through the valley to the intercepting ditch at the bottom of the slope.

[0012] Furthermore, the surface polyethylene ecological honeycomb net is marked with the up and down directions of laying the film vegetation bags.

[0013] Furthermore, the steel wire mesh covers the surface of the film vegetation bag and fixes the film vegetation bag together with the locking soil nails to prevent the film vegetation bag from sliding down, falling off, or being misplaced.

[0014] Furthermore, the four corners of the film vegetation bag are respectively provided with connecting locks, and the locking soil nails pass through the wire mesh and the connecting locks and are inserted into the soil or rock mass of the slope; the connecting plate nails are placed one at a 20 cm interval on the surface of the film vegetation bag.

[0015] Furthermore, the locking soil nails connect the single film vegetation bags into a conjoined film vegetation bag through the connecting locks, so that the slope can form a whole.

[0016] Further, the method comprises the following steps.

[0017] S1. Prepare, clean and level the slope surface before construction.

[0018] S2. Drill holes, make anchor rods, and install anchor rods. When the slope is a soil layer, the specifications and depth of anchor rods shall be based on relevant specifications. When the slope is a rock layer, the length of the anchor rods shall be 1.2 meters, the diameter shall be 12 mm, the horizontal spacing shall be 40 to 60 cm, the vertical spacing shall be 1 to 2 meters, the depth of anchor rods shall be no less than 70 cm, and the length exposed outside the slope shall be no less than 30 cm.

[0019] S3. The film vegetation bags are produced, packaged and transported by professional manufacturers.

[0020] S4. Soil preparation: The soil can be obtained near the construction site and samples can be collected and sent for testing to see if the soil composition meets the requirements for vegetation growth. Nutrient matrix soil should be prepared, and the planting soil, organic matrix, water retaining agent, fertilizer, and vegetation seeds in the film vegetation bags should comply with relevant regulations.

[0021] S5. When assembling the nutrient matrix soil and ordinary soil separately, the film vegetation bags should be filled as densely as possible, and the compaction degree is recommended to be above 70%. After filling to 80%, the bag body should be patted into shape, and the film vegetation bags should be uniformly sealed with professional sewing equipment.

[0022] S6. After the film vegetation bags are sealed, they are uniformly conveyed to the designated position of the slope using a climbing cantilever conveyor belt. The chassis of the climbing cantilever conveyor belt has a movable wheel hub at the bottom of the slope. The cantilever length of the climbing cantilever conveyor belt can be appropriately lengthened or shortened according to the actual length of the slope. Construction workers are arranged to lay the film vegetation bags in a flat-laying manner. During laying, the bottom of the film vegetation bags should be close to the soil or rock mass, and the film vegetation bags should be tightly connected without leaving any gaps.

[0023] S7.Fix the film vegetation bags with locking soil nails while laying. When the slope is a soil layer, the locking soil nails can be driven directly into the soil layer. When the slope is a rock layer, drill holes in the rock with an electric drill and then drive the locking soil nails in to fix it. Fill the corners and gaps with small film vegetation bags and fix them with locking soil nails. The long sides of the film vegetation bags are connected with connecting plate nails.

[0024] S8. After the film vegetation bag is laid, lay the wire mesh on the surface of the film vegetation bag in time; and fix the wire mesh with tying wire.

[0025] S9. To further realize the present invention, after the film vegetation bags are laid, the first water must be ensured to be thoroughly watered. Watering should be done in the morning and evening. Watering should be done every day until the vegetation seeds emerge. When the grass seedlings grow to 5-6 cm or 2-3 leaves, it is appropriate to water once every 2-3 days. One month after emergence, compound fertilizer can be appropriately applied. Compound fertilizer should be applied after rain to prevent rain from washing away the fertilizer. After the plants grow to 30-40 cm, it is appropriate to water them once a week according to weather conditions. When the weather is dry, the number of watering can be increased. After 3 months of maintenance, the number of watering can be appropriately reduced. Mainly rely on natural rainfall for self-maintenance, but if the weather is dry for a long time, it should be watered and maintained appropriately; during the maintenance period, pay attention to the prevention and control of diseases and pests.

[0026] Beneficial effects of the present invention.

[0027] 1. The present invention proposes a slope protection ecological film vegetation bag and a construction method thereof, which adopts two layers of nutrient soil and ordinary soil and is separated by thickened non-woven cotton fiber cloth. While the thickness of the nutrient matrix soil layer meets the vegetation growth requirements, it also saves the cost of composite nutrient matrix soil fertilizer.

[0028] 2. After the film vegetation bags are bagged, they are sealed with professional mechanical equipment and pressed into two rows horizontally. The film vegetation bags are separated and divided to keep the density of vegetation seeds in the film vegetation bags as consistent as possible, which can effectively enhance the anti-scouring ability of the film vegetation bags and the integrity of the film vegetation bags, and is conducive to the growth of vegetation seeds in the film vegetation bags.

[0029] 3. A large number of valleys are formed at the joints between the individual film vegetation bags and at the separation points where the vegetation bags are divided into two rows. The water on the top of the slope can flow along the valleys to the intercepting ditches at the bottom of the slope, reducing the scouring ability of rainwater on the film vegetation bags and protecting the durability of the film vegetation bags.

[0030] 4. The film vegetation bag connecting buckle is not only a connecting device between film vegetation bags, but also a part of the device for fixing film vegetation bags. The connecting buckle can connect single film vegetation bags into a conjoined film vegetation bag, ensuring that there is no gap at the connection of the film vegetation bag, which is beneficial to protecting the integrity and integrity of the slope ecology and is more beautiful.
