The ecological green grid is a new type of material structure which is widely used in transportation, water conservancy, municipal garden, soil and water conservation and other engineering projects. It realizes the organic combination of engineering structure and ecological environment. Compared with some traditional rigid structures, it has its own advantages. Therefore, it has become a structural type for protecting riverbed, controlling landslide, preventing debris flow, preventing rockfall and giving attention to environmental protection all over the world

The gabion ecological green grid is a new type of material structure widely used in engineering projects such as transportation, water conservancy, municipal administration, gardens, and water and soil conservation. Compared with the rigid structure, it has its own advantages, so it has become a structural type in the world to protect riverbeds, control landslides, prevent mud-rock flows, and prevent rockfall while taking into account environmental protection.

In the summer in the south, because of the humid environment, gabion mesh is still used more, especially the gabion mesh with higher gabion content, the life span and tensile condition are also improving. During the summer construction period, protection measures are required Do a good job to prevent accidental shedding in metal materials. The strength of the gabion grid is relatively high. In the later construction environment, it can effectively support the actual use effect of the gabion grid, and it is gradually becoming the focus of construction at present.

Another major feature of the gabion grid is the maintenance measures during the summer construction period. As we all know, the requirements for construction and transportation of gabion nets are not relatively strict. When stacking, they still need to be put into loose storage. For example, when placing gabion nets, simple treatment will have a better effect.

In the process of installation or in the case of opening, review the plastic, it may be partially damaged by external factors, from the signs of damage on the surface and test data show that this damage is only partial and temporary, and will not cause damage to the integrity of the mesh surface collapse. When designing the wire mesh grid, it is not necessary to consider the bearing capacity of the overall structure of the grid, and local damage will not affect the overall bearing capacity. The protective structure of the gabion grid is installed under the action of its own gravity. The weight will gradually increase, and the unfilled space will be reduced. When installing on soft ground, you can install more to strengthen the protection.

The mesh structure of the gabion allows vegetation to grow, thereby maintaining ecological integrity. The gabion structure has great impact resistance, it is a huge whole, it is not easy to be washed away, and it is not easy to break through from a certain part. It is a permeable structure that does not completely block the water flow, so it can better disintegrate the impact of the water flow. It is a deformable structure. If part of the base is emptied, it can sink naturally to fill the vacancy by virtue of its own gravity, preventing the emptied part from further deteriorating.

Due to the joint action of iron, water, and oxygen, iron reacts with them to form rust, especially in coastal areas, because Nacl is contained in water, it can form freely moving electrons after being dissolved in water, and the electrons and the electrons in the outer layer of Fe Interchange occurs, so corrosion is accelerated. The commonly used anti-corrosion methods for gabion wire mesh include galvanizing, galvanizing, and plastic coating on the surface of the steel wire. However, in seawater and heavily polluted areas, although the chemical properties of zinc and aluminum are more active than iron, they can be used first. Corrosion protects the iron, but the environment is harsh and the corrosion is extremely fast, and the time for protecting the gabion mesh cannot meet the needs of the project.
