Description

Technical Field

[0001] This utility model relates to the field of natural disaster prevention equipment, specifically to a grid-type gabion structure for solidifying and blocking debris flow channels. Background Technology

[0002] Gabions are essentially cages made of woven metal mesh filled with stones, used to replace traditional concrete walls for protection and stability. Key features include: 1. High flexibility: Unlike rigid cement walls that are prone to cracking, they can adapt to ground settlement and deformation. For example, after an earthquake, they may deform but will not easily collapse. 2. High permeability: The gaps between the stones allow water to pass freely, effectively draining moisture from the soil, reducing water pressure, and preventing the structure from being washed away. This characteristic is unmatched by concrete. 3. Durable and robust: The metal mesh is usually galvanized or plastic-coated for corrosion protection, making it highly resistant to rust. The stones inside are not afraid of wind and sun, resulting in a long overall lifespan. 4. Simple construction and low cost: No large machinery is needed; simply assemble the empty cages and fill them with stones. Stones can be sourced locally, greatly saving on material and transportation costs. 5. Eco-friendly: Soil accumulates in the gaps between the stones, allowing plants to grow and blending perfectly with the natural environment, promoting ecological restoration.

[0003] Currently, Chinese patent CN222349576U discloses an ecological steel-plastic gabion and an ecological slope protection structure composed of gabions. It includes multiple coal gangue blocks and a steel-plastic mesh; the multiple coal gangue blocks are arranged sequentially along their length or width, and the steel-plastic mesh covers the upper part of the multiple coal gangue blocks. The coal gangue blocks and the steel-plastic mesh are connected by gabion anchors. This utility model is used for riverbank protection, building and road slope protection.

[0004] While this type of ecological steel-plastic gabion and the ecological slope protection composed of gabions have solved the problems of the gabion box being made of metal materials such as steel bars, which are prone to rust, and the filling stones used need to be excavated and transported from other places, which damages the ecology of the mining mountain, they are often unable to effectively contain debris flow channels. Summary of the Invention

[0005] The purpose of this invention is to provide a grid-type gabion structure for solidifying and blocking debris flow channels. It has the advantages of effectively buffering debris flow, reducing the impact force of debris flow, preventing large impurities from being carried downstream, and reducing the harmfulness of debris flow.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A gabion structure for solidifying and blocking debris flow channels includes a gabion base, the gabion base including a base, the base being surrounded by a metal woven mesh grid, the top of the mesh grid being a sealing plate, and an energy dissipation device inside the gabion base, the energy dissipation device including a support column located on the gabion base, the support column being provided with a rotating cap rotatably connected to the support column, and the rotating cap being provided with several energy dissipation blades.

[0007] By adopting the above technical solution, the energy dissipation blades can reduce the impact of debris flow to the greatest extent. At the same time, the gabions can effectively block some large particles of mud, sand and gravel, greatly reducing the damage caused by debris flow.

[0008] Further features: A water storage tank is also provided around the support column.

[0009] By adopting the above technical solution, the water storage tank can effectively increase the weight of the entire gabion on the one hand, and on the other hand, provide the corresponding channels for water flow.

[0010] Further features: The base is also provided with a water inlet channel connected to the water storage tank, and a water outlet channel is also provided on one side of the base.

[0011] By adopting the above technical solution, the mesh grid has two layers, and stones are placed inside the mesh grid.

[0012] Further design: The mesh grilles on both sides can effectively filter large stones, while the stones placed inside can effectively increase the weight to prevent the entire device from being destroyed, and can further filter impurities, allowing only some small particles or rainwater to pass through.

[0013] By adopting the above technical solution, a trapezoidal weight-increasing platform is also provided below the gabion base.

[0014] Further features: The added weight-adding platform can better help increase the weight of the entire equipment and reduce the possibility of damage.

[0015] In summary, this utility model has the following beneficial effects: it can effectively reduce the impact force of debris flow, while reducing the downward flow of large particles of impurities, thereby reducing the degree of damage. At the same time, the energy dissipation blades can better reduce the kinetic energy of the water flow, thereby reducing the impact force. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] The technical solution adopted in this utility model is: a grid-type gabion structure for solidifying and blocking debris flow channels, such as... Figure 1 and Figure 2 As shown, the structure includes a gabion base 1, a trapezoidal weight-increasing platform 10 below the gabion base 1, a base 2, a metal woven mesh grid 3 around the base 2, two layers of mesh grid 3, stones 9 inside the mesh grid 3, and a sealing plate 4 at the top of the mesh grid 3. An energy dissipation device 5 is also provided inside the gabion base 1. The energy dissipation device 5 includes a support column 51 located on the gabion base, a water storage tank 6 around the support column 51, and a rotating cap 52 rotatably connected to the support column 51. Several energy dissipation blades 53 are provided on the rotating cap 52. A water inlet trough 7 connected to the water storage tank 6 is also provided on the base 2, and a water outlet trough 8 is provided on one side of the base 2.

[0021] Its main working principle is as follows: During use, the gabion base 1 is placed in the appropriate place. When a debris flow occurs, the debris flow passes through the mesh grid 3 and then through the stones 9 to block large particles of impurities to the outside, thus buffering it first. At the same time, the energy dissipation blades 53 inside the device buffer the water after it has been filtered by the debris flow and slowly discharge the water through the outlet trough 8, thereby further reducing the damage caused by the debris flow. Even if some mud and sand enter the interior and fill the water storage tank 6, it will further increase the weight of the gabion itself, thus making it more stable.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the utility model's technical solution.
