Steel plastic geogrid used in mining is made of high-strength steel wire (or other fibers) and polyethylene (PE) with special treatment and other additives, which is extruded into composite high-strength tensile strip with rough embossing on the surface. The single belt is weaved or clamped according to a certain distance longitudinally and transversely, and the joint point is welded with the fusion welding technology of special strengthened bonding to form a reinforced steel plastic geogrid used in mining.

Tensile test method for steel plastic geogrid used in mining: separate the steel plastic from the outer plastic, and do not damage the steel wire when separating. The tensile force of a single 0.7mm steel wire is 850n-900n. The calculation method is: multiply the number of steel wires by the tensile force of a single steel wire and then divide the mesh size into the tensile force of steel plastic grid. Take 50kn8 0.7mm steel wires as an example, the tensile force is 850n * 8 ÷ 125 (mesh) = 54.4kn

What are the characteristics of steel plastic geogrid used in mining

1. Steel plastic geogrid used in mining has the advantages of high strength, small creep and adaptability to all kinds of environmental soil, which can completely meet the use of high retaining wall in high-grade highway.

2. Steel plastic geogrid used in mining can effectively improve the embedment and occlusion of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrict the lateral displacement of the soil, and enhance the stability of the foundation.

3. Compared with the traditional geogrid, steel plastic geogrid used in mining has the characteristics of high strength, strong bearing capacity, anti-corrosion, anti-aging, large friction coefficient, uniform hole, convenient construction and long service life.

4. Steel plastic geogrid used in mining is more suitable for deep sea operation and bank reinforcement, which fundamentally solves the technical problems such as low strength, poor corrosion resistance and short service life caused by long-term seawater erosion of gabions made of other materials.

5. Steel plastic geogrid used in mining can effectively avoid the construction damage caused by the rolling and damage of machines and tools in the construction process.

2、How to construct the steel plastic geogrid used in mining:

1. The laying surface of steel plastic geogrid used in mining shall be relatively flat. After the laying layer passes the acceptance, in order to prevent the longitudinal deflection, first draw a white line or hanging line in the laying layer according to the width, and then start the laying, and then fix the end of the grid with U-shaped nails (4 nails per meter of width, fixed at a uniform distance).

2. After fixing the end of steel plastic geogrid used in mining, use the paver or manual method to slowly pull the grid forward, and manually straighten it once every 10 meters until one roll of the grid is paved, and then pave the next roll. The operation is the same as before.

3. Joint laying: take the roll length as the section length of laying. After the section length of steel plastic geogrid used in mining is fully paved, check the laying quality as a whole, and then lay the next section. When the next section is laid, the net distance between the grid and the grid overlaps for the lap length, and then continue to lay the second section in the forward direction after being fixed with binding wire. The operation requirements are the same as before.

Grating, also known as steel grating, steel grating or grating plate, is welded by flat steel and twisted steel. The main purpose of grating is to rest platform, walkway, ditch cover and step plate. Also used in environmental protection equipment and sewage treatment, because of its advantages, it is widely used. The gap width between grid bars can be set according to the way of removing dirt and the requirements of water pump. Generally, the gap of manual cleaning grid is 16-25mm. The grid in front of the grit chamber or sedimentation tank is generally 15-30mm, with a maximum of 40mm. There are three kinds of commonly used mechanical slag cleaning equipment, namely, chain type, mobile type and wire rope traction type. According to the difference of grid spacing, grid can be divided into three types: coarse grid, medium grid and fine grid. According to the cleaning method of the grid, there are three ways: manual grid, mechanical grid and hydraulic grid. According to the different structural characteristics of the grid, it can be divided into grab rake type, circular type, arc type, rotary type, drum type, rotary type, tooth rake type and ladder type. The grid equipment is generally used on the inlet channel of sewage treatment or at the inlet of the sump of the lifting pump station. Its main function is to remove the larger suspended or floating objects in the sewage, so as to reduce the treatment load of the subsequent water treatment process and protect the water pump, pipeline, instrument, etc. When the amount of grid slag intercepted is greater than 0.2m3/d, mechanical slag removal is generally used; when the amount of grid slag is less than 0.2m3/d, manual slag removal or mechanical slag removal can be used. Steel plastic geogrid used in mining is also used in construction, design and decoration, sewage treatment, engineering applications and other fields.
