Gabion Box

According to ASTM and EN standards, the diameter of mild steel wire used varies according to engineering design requirements. Generally between 2.0-4.0mm, the tensile strength of the gabion wire is not less than 38kg/m2, the weight of the metal coating is generally higher than 245g/m2, and the diameter of the edge line of the gabion mesh is generally larger than the diameter of the wire. The length of the twisted part of the pair of wires shall not be less than 50mm to ensure that the metal coating and PVC coating of the steel wire in the twisted part are not damaged.

Features: 1. The flexible structure can adapt to the change of the slope without being damaged, and has better safety and stability than the rigid structure; 2. It has strong anti-scouring ability and can withstand the water flow speed up to 6m/s; 3. The structure is permeable in nature, and has a strong tolerance to the natural action and filtration of groundwater. The suspended matter and silt in the water can be deposited in the rock filling crevices, which is conducive to the growth of natural plants and gradually restores the original ecological environment.

The gabion net bag is rolled from a single layer of mesh. Its mesh, mesh, galvanized and PVC coating properties are the same as those of the cage. This product can put rocks of different shapes and sizes into the alloy net bag to form a flexible whole, and can reach the designated place by hoisting, trucking, and shipping, and the alloy net bag can be connected to each other to form a larger whole. It is convenient, fast and efficient to invest, and has good economic performance.

Uses:

Gabion nets can be used for slope support, foundation pit support, mountain rock surface hanging net spraying, slope vegetation (greening), railway and expressway isolation protection barriers, and it can also be made into cages and mesh pads for rivers and rivers , Anti-scouring protection of dykes and seawalls, and net cages for reservoirs and river closures. The most serious disaster of the river is that the water scours the river bank and destroys it, causing floods, resulting in a large loss of life and property and a large amount of soil erosion. Therefore, when dealing with the above problems, the application of the ecological grid structure becomes one of the best solutions, which can protect the riverbed and banks for a long time.

●Control and guide rivers and floods

The most serious disaster of the river is that the water scours the river bank and destroys it, causing flooding, causing a large loss of life and property and a large amount of water and soil erosion. Therefore, when dealing with the above problems, the application of the grid ecological grid structure is one of the best solutions, which can protect the riverbed and banks for a long time.

●Channel canal bed

The construction of the channel involves the stability of the slope and the riverbed. Therefore, the selection of ecological grid structure is the main method adopted in many natural river reconstruction and artificial channel excavation in the past century. It can effectively protect the river bank or river bed, and it also has the function of controlling the flow of water and preventing water loss, especially in environmental protection and water quality maintenance.

●Slope revetment

The application of ecological grid structure and river revetment and its slope toe protection is a very successful example. It gives full play to the advantages of ecological grid and achieves the ideal effect that cannot be achieved by other methods.

Reinforced gabion nets are also called reinforced gabion nets, hanging nets, stone mesh belts, mountain protection nets, etc., when weaving hexagonal nets, add straight iron wires, or iron wires woven in vertical or parallel directions. . The tensile strength of reinforced heavy-duty hexagonal mesh is higher than that of ordinary mesh, and the diameter of reinforced wire is generally not smaller than that of side wire. There is no creep problem. Reinforced gabion net is a new technology of reinforced soil engineering. It uses low-carbon steel wire as the basic material, and the steel wire has been treated by hot-dip galvanizing and special plastic-coating process, which has good corrosion resistance and wear resistance. These steel wires are mechanically woven into a mesh surface, and then manufactured into different products according to their use as a structure. Material: low carbon steel wire.

Features:

1. The reinforced gabion mesh retaining wall has technical characteristics and advantages such as safety, flexibility, permeability, durability, environmental protection, and economy.

2. A highly finished product. The face wall and the reinforcement belt are also connected without joints, which eliminates the disadvantage that the joints of the components are easy to become structural weaknesses. The prefabricated construction is convenient and fast, and the work efficiency is high.

3. It is an ecological protection net. Because the wall panel is not the concrete rigid panel of the traditional reinforced earth retaining wall, the wall surface can be naturally permeable, which is conducive to the discharge of groundwater in the fill, ensuring the long-term stability of the structure, and the wall has good rigidity, and there is no "bulging" phenomenon.

Uses:

1. It can be used to reinforce embankments of rivers. The gabion net cages for strengthening the river embankment are generally inside the embankment, and are mainly used in places where the river flow is relatively fast. The river water washes the gabion net instead of directly washing the river embankment, so as to reduce the damage to the river embankment.

2. Reinforced gabion net can also be used to guide river water. Rivers generally flow along the inherent river channel, and the river channel may have a naturally formed curved channel. In the event of a flood, the water volume is huge and the water flow is turbulent. Levees may divert rivers, which will cause huge disasters.

3. Nets are also applied to flood discharge dams and diversion dams to guide or restrain floods.

4. At the same time, it is also widely used in roads, railways, construction and other fields, with good engineering benefits, economic benefits and environmental benefits
