Steel-plastic geogrid is a major geosynthetic material. With high-strength steel wire (or other fibers), specially treated with polyethylene (PE) or polypropylene (PP), and other additives are added to make it a composite high-strength tensile strip through extrusion, and the surface has Rough embossed is a high-strength reinforced geotechnical belt. This single belt is made or arranged at a certain distance vertically and horizontally, and is welded with a special reinforced bonding fusion welding technology to form, which is a reinforced Geogrid.

Features:

1. Compared with traditional grilles, it has more characteristics such as strength, strong bearing capacity, corrosion resistance, anti-aging, friction coefficient, uniform eyelets, convenient construction, and long service life.
2. It can effectively avoid construction damage caused by crushing and destroying the machine during construction.

characteristic:

1. The tensile force of the steel-plastic composite grille is borne by the high-strength steel wire woven by warp and weft, which produces extremely high tensile modulus under low strain capacity. The vertical and horizontal ribs work together to give full play to the clamping effect of the grille on the soil.
2. The steel wire warp and weft of the longitudinal and transverse ribs of the steel-plastic composite grille are weaved into a mesh. The outer wrapping layer is formed at one time. The steel wire and the outer wrapping layer can work in a coordinated manner, and the elongation of the damage is very low (not greater than 3%). The main stress unit of steel-plastic composite geogrid is steel wire, with extremely low creep.
3. Through the treatment of the plastic surface during the production process, rough patterns are pressed to enhance the roughness of the grille surface and improve the friction coefficient between the steel-plastic composite geogrid and the soil.
4. The width of the steel-plastic composite grille can reach 6m, achieving efficient and economical reinforcement effect.
5. The high-density polyethylene used in steel-plastic composite grille can ensure that it will not be eroded by acid, alkali, salt solutions or oils at room temperature; it will not be affected by water dissolution or microorganisms. At the same time, the polymer properties of polyethylene are sufficient to resist aging caused by ultraviolet radiation. After the grille is subjected to stress, the vertical and horizontal ribs work together, and no cracking or damage of the nodes will occur. In actual projects, after compacting the filler, it is not eroded by ultraviolet light and oxygen, so it can fully meet the requirements of permanent engineering construction.

Engineering application fields: soft ten foundations, retaining walls and road crack-resistant engineering, etc., such as roads, railways, abutments, guideways, docks, dams, slag yards, etc.

Engineering functions:

1. It has high strength, small creep, and is adapted to various environmental soils. It can fully meet the use of tall retaining walls in high-grade highways.
2. It can effectively improve the locking and joint function of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.
3. Compared with traditional grilles, it has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform eyelets, convenient construction, and long service life.
4. It is more suitable for deep-sea operations and embankment reinforcement, and fundamentally solves the technical problems such as low strength, poor corrosion resistance and short service life caused by long-term erosion of other materials.
5. It can effectively avoid construction damage caused by crushing and destroying the machine during construction.
