The steel plastic geogrid is made of high-strength steel wire (or other fibers), special treatment, polyethylene (PE) or polypropylene (PP), and other additives. It is extruded into composite high-strength tensile strip, and then welded. Laying, lapping and positioning are easy, construction is simple, and project cost can be effectively saved. Steel plastic geogrid is widely used in civil engineering such as railway, highway, abutment, embankment, environmental protection building, soft soil foundation reinforcement, slope protection and pavement crack resistance. Steel plastic geogrid used in water conservancy also plays an important role.

Advantages of steel plastic geogrid used in water conservancy:

1. The steel plastic geogrid has high strength and low creep;

2. Steel plastic geogrid is corrosion-resistant and has long service life;

3. Steel plastic geogrid can greatly enhance the bearing capacity and stability of the foundation;

The steel plastic geogrid can overcome the huge tensile resistance in the process of use, and has more advantages than other products to some extent. The tensile force of the steel plastic composite geogrid is borne by the high-strength steel wire woven by warp and weft. Under the low strain capacity, the tensile modulus of the geogrid is very high. The longitudinal and transverse ribs work together to give full play to the role of the grid in the soil.

The steel wire of the longitudinal and transverse ribs of the steel plastic composite geogrid is weaved into a net by warp and weft, and the outer wrapping layer is formed at one time. The steel wire and the outer wrapping layer can coordinate, and the elongation at failure is very low (no more than 3%). The main stress element of steel plastic composite geogrid is steel wire with very low creep.

Steel plastic geogrid is a kind of geosynthetic material, which is composed of steel plastic composite reinforcement belt (built-in high-strength carbon spring steel wire (stress material) and coated with polyethylene resin (protective material), arranged at right angles to the plane longitude and latitude, and welded by ultrasonic wave. Steel plastic geogrid is a comprehensive product of existing rigid steel bars (flat steel strip, ribbed steel strip, galvanized steel strip, stainless steel strip, reinforced concrete strip, etc.) and flexible steel bars (polypropylene strip, plastic geogrid, warp knitted grid, etc.). Due to the large tensile strength, low elongation (< 3%), small creep and strong interlocking and occlusion effect on the soil, the steel plastic geogrid can effectively treat the soft soil foundation, restrain the lateral displacement of the soil, overcome the uneven settlement of the soil, greatly enhance the bearing capacity of the foundation and improve the overall performance of the foundation. The steel plastic geogrid can be widely used in the road The reinforcement and strengthening of road engineering, railway engineering, retaining structure and dam engineering, water conservancy engineering, tunnel engineering, steel plastic geogrid to resist rutting and prevent pavement cracking, etc. all have significant guarantee effect and good social and economic benefits.

1. The steel wire of the longitudinal and transverse ribs of the deformation and breaking elongation steel plastic geogrid is woven into a net by warp and weft, the outer wrapping layer is formed once, the steel wire and the outer wrapping layer can coordinate, and the breaking elongation is very low (no more than 3%). The steel wire is the main stress element of plastic steel geogrid, and the creep variable is very low.

2. The friction coefficient is processed by the plastic surface in the production process, and the rough pattern is pressed to enhance the roughness of the grid surface and improve the friction coefficient between the two-way steel plastic geogrid and the soil.

3. the width of the two-way steel plastic geogrid can reach 6m to achieve efficient and economic reinforcement effect.

4. The high-density polyethylene of aging and durable steel plastic geogrid can ensure that it will not be eroded by acid, alkali and salt solution or oil under normal temperature, and will not be damaged by water dissolution or microorganism. At the same time, the polymer properties of polyethylene are enough to resist the aging caused by ultraviolet radiation. After the grid is stressed, the longitudinal and transverse ribs work together, and there will be no crack or damage of nodes. However, in the actual project, after the compaction of the filler, because it is not eroded by ultraviolet light and oxygen, it can completely meet the requirements of permanent project construction.

5. The steel plastic geogrid has the advantages of high strength, small creep and adaptability to all kinds of environmental soils, which can completely meet the use of high retaining walls in high-grade highways.

6. The steel plastic geogrid 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.

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

8. Steel plastic geogrid is more suitable for deep sea operation and bank reinforcement. 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 are fundamentally solved. It can effectively avoid the construction damage caused by the traditional grid being rolled and damaged by machines and tools in the construction process.
