Description

Technical Field

[0001] This utility model relates to the field of geological environment management and geological disaster prevention technology, and in particular to a flexible water-blocking dike based on vegetation bags. Background Technology

[0002] Currently, dikes are protective structures used to control and guide water flow, typically for preventing soil erosion, protecting soil, and directing water to designated areas. They have wide applications in agriculture, soil and water conservation, river management, and flood control in mountainous areas.

[0003] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:

[0004] 1. Traditional water-cutting dikes are usually constructed with clay or concrete, reinforced concrete, masonry, etc., which have very low permeability. They are rigid structures and are prone to cracking when the terrain changes or over time.

[0005] 2. Traditional rigid dikes only serve the single function of intercepting upstream water flow and reducing erosion, and cannot simultaneously provide a favorable environment for plant growth, which is inconsistent with the current concept of ecological and environmental protection. Utility Model Content

[0006] To address the technical problems mentioned above, this utility model provides a flexible water-blocking dike based on vegetation bags.

[0007] The present invention is achieved by the following technical solution: a flexible water-cutting dike based on vegetation bags includes: a layer of vegetation bag one and a layer of vegetation bag two set on the top surface line of the slope, wherein the layer of vegetation bag one and the layer of vegetation bag two are stacked alternately.

[0008] Both the first and second planting bags are filled with nutrient soil, and the nutrient soil contains plant seeds.

[0009] The first layer of planting bags and the second layer of planting bags are each composed of multiple first planting bags and multiple second planting bags, and the gaps between the multiple first planting bags and the multiple second planting bags are respectively filled with cement mortar first and cement mortar second.

[0010] The above technical solutions can be used to form a water-blocking dike to intercept upstream water flow on the slope and reduce slope erosion. Moreover, the water-blocking dike is a flexible structure that can adapt to changes in terrain and is not easily broken. While preventing geological disasters, the planting bags are filled with nutrient soil and plant seeds, which is conducive to plant growth and conforms to the concept of ecological and environmental protection. It can also play a positive role in improving the ecological environment.

[0011] As a further improvement to the above scheme, a topsoil layer, a coconut fiber blanket, and a three-dimensional soil stabilizing net mat are provided between the first and second planting bags. The topsoil layer is laid on top of a layer of planting bags and the corresponding cement mortar.

[0012] As a further improvement to the above scheme, the first coconut fiber blanket is laid on top of the first topsoil, the first three-dimensional soil stabilization mat is laid on top of the first coconut fiber blanket, and the second topsoil is laid on top of the second vegetation bag.

[0013] As a further improvement to the above scheme, a coconut fiber blanket is laid on top of the top layer of soil II, and a three-dimensional soil stabilization mesh is laid on top of the coconut fiber blanket II.

[0014] As a further improvement to the above solution, both the first and second coconut fiber mats are made of natural coconut fiber, and both the first three-dimensional soil stabilizing net mat and the galvanized wire mesh are made of multi-layer plastic three-dimensional soil stabilizing net mats made of thermoplastic resin. The natural coconut fiber has good degradability and environmental friendliness. The natural coconut fiber not only does not pollute the environment, but can also naturally degrade into organic fertilizer, providing additional nutritional support for the growth of vegetation. The multi-layer plastic three-dimensional soil stabilizing net mat has a three-dimensional structure similar to a loofah network, with a loose and flexible texture, which can provide 90% space for soil, gravel and fine stones, promote the deep development of plant roots, and form a solid green protective layer.

[0015] The above technical solutions can promote plant growth, conform to the concept of ecological and environmental protection, and play a positive role in improving the ecological environment.

[0016] As a further improvement to the above scheme, a pit is opened on the top surface of the slope. The pit is 100mm deep. The bottom of the first planting bag is inserted into the pit. Both the first planting bag and the second planting bag are wrapped with galvanized wire mesh. The first planting bag, the first topsoil, the first coconut fiber blanket, the second planting bag, the second topsoil, and the second coconut fiber blanket are all fixed by multiple anchor rods.

[0017] As a further improvement to the above scheme, the dimensions of both the first and second planting bags are 800mm×400mm, the height after being filled with soil is 150mm, the fabric specifications are thickness ≥1.3mm, weight ≥150g / m2, and tensile strength ≥4.5kN / m.

[0018] As a further improvement to the above scheme, the anchor rod is divided into a main anchor rod and an auxiliary anchor rod. The main anchor rod is made of φ16mm HRB400 steel bar, 1m long, and arranged at a spacing of 800mm. The auxiliary anchor rod is made of φ16mm HRB400 steel bar, 0.6m long, and arranged at a spacing of 800mm. The anchor heads of both the main anchor rod and the auxiliary anchor rod are welded with horizontal bars to form a T-shape, and the horizontal bars are 200mm long.

[0019] The above technical solution can ensure the firmness of the connection between the first planting bag, the first topsoil, the first coconut fiber blanket, the second planting bag, the second topsoil, the second coconut fiber blanket and the anchor rod.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model solves the problem of intercepting upstream water flow on slopes and reducing slope erosion by forming a water-blocking dike. Moreover, the water-blocking dike is a flexible structure that can adapt to changes in terrain and is not easy to break. While preventing geological disasters, the planting bags are filled with nutrient soil and plant seeds, which is conducive to plant growth and conforms to the concept of ecological and environmental protection. It can also play a positive role in improving the ecological environment. Attached Figure Description
