Description

Gabion basket, also commonly known as gabion box, is a structure made of corrosion resistant, high strength, good ductility galvanized wire or PVC coated wire through mechanical weaving. This kind of structure is widely used in dam protection, seawall reinforcement, retaining wall construction and channel lining. Gabion basket and gabion mat as a stone container, the internal evenly divided into a number of units, can be connected with other containers, and fill the stone in the field, forming a flexible and permeable overall structure. Such a design can not only effectively control and direct the flow of water or flood, but also protect the safety of DAMS and sea walls to a certain extent.

Gabion net is a special form of gabion basket, especially suitable for large flow rate, serious erosion and bank slope seepage of slow beach areas. As a flexible structure, Gabion mesh has a good self-adjusting ability to the ground uneven settlement and can adapt to various complex terrain conditions. In addition, due to its surface has a certain porosity, the gap between the stones provides a habitat space for animals, but also conducive to the growth of plants, which is of great significance for the protection of the ecological environment. Above the water line, guest soil bags can also be planted to further meet ecological considerations and safety requirements.

In terms of materials, the stone cage basket mainly uses the following materials:

Galvanized steel wire: The selection of high-quality low carbon steel wire, the diameter range from 2.0MM to 4.0MM, tensile strength of at least 380Mpa. The surface of the steel wire is hot-dip galvanized, and the thickness of the galvanized layer is customized according to customer requirements, up to 300g/m².

Zinc-5% aluminum (10% aluminum) - mixed rare earth alloy steel wire: This is an internationally emerging material, compared to the traditional pure galvanized steel wire, its corrosion resistance has increased by more than three times. The diameter of this type of wire is between 1.0MM and 3.0MM, and the tensile strength is not less than 1380Mpa.

Galvanized steel wire covered with PVC: based on high-quality low carbon steel wire, a layer of PVC protective film is added to the outer layer and then woven. This can not only enhance the protective effect against highly polluted environments, but also better integrate into the surrounding environment by choosing different colors of products.

Zinc-5% aluminum (10% aluminum) -mixed rare earth alloy steel wire coated PVC: similar to the third material above, but here refers to the practice of covering the outer surface of zinc-5% aluminum - mixed rare earth alloy steel wire with a layer of PVC protective layer.

Whether from a functional or aesthetic point of view, the stone cage basket is an indispensable part of modern water conservancy projects. It can not only effectively solve problems such as flood control and drainage, but also take into account the needs of ecological protection, reflecting the concept of harmonious coexistence between man and nature.

The application of stone cage net

As a flexible and efficient engineering solution, gabion baskets are widely used in many fields, including hydraulic engineering, highway construction, railway engineering and levees. Its main functions are to control and direct water flow or flooding, prevent rock breakage, protect soil and water, strengthen soil structure, and provide protection in coastal areas. The following are some specific applications and engineering cases of stone cage mesh:

1. Control and direct water or flood

Flood levee or guide levee: through the construction of stone cage mesh wall to form a flood control levee or guide levee, effectively manage the flow of the river, reduce the damage caused by flooding.

River management: Used for river regulation projects, such as adjusting river bed shape, increasing water cross section area, and improving water flow conditions.

2. Prevent rock breakage and water and soil conservation

Slope stability: the use of stone cage mesh on both sides of the mountain road slope protection treatment to prevent landslides; It can also be used in areas with severe bank erosion.

Vegetation restoration: Because its structure allows plant roots to grow through, it helps to promote the restoration and development of the local ecological environment.

3. Bridge pier protection and other infrastructure reinforcement

Bridge foundation protection: The arrangement of stone cage nets around the pier can resist the damage caused by water impact and extend the service life of the bridge.

Tunnel mouth support: For the tunnel entrance located in the soft land zone or the area prone to settlement, the stone cage net is used as an external supporting material to enhance the overall stability.

4. Coastal protection engineering

Seawall construction: Coastal areas often face the threat of storm surge invasion, the use of stone cage net to build a durable seawall can effectively resist wave erosion.

Port pier reinforcement: In order to improve the safety of port facilities, stone cage mesh barriers can be set up at the front of the pier to reduce the damage caused by the opposite wall when the ship docks.

Summary of the advantages of stone cage net

Strong adaptability: It can adapt well to changes in the foundation and maintain stability even in the case of uneven settlement.

Good durability: Excellent corrosion resistance and erosion resistance, suitable for long-term exposure to the outside environment.

High flexibility: even if subjected to strong external force is not easy to break, can withstand a large degree of deformation without collapse.

Water permeable/impermeable Optional: Select an appropriate type based on actual requirements to avoid damage caused by hydrostatic force.

Environment friendly: It is conducive to plant growth, so that the project is more natural and beautiful into the surrounding landscape.

Simple and fast construction: installation can be completed without complex equipment and technology, greatly reducing labor costs and time consumption.

Economical and efficient: lightweight and easy to transport (foldable), fast and easy to assemble on site, significantly reducing logistics costs.

Stone cage net has become one of the ideal choices to solve the engineering construction problems under various complex geological conditions worldwide.
