This product is made of high-strength steel wire (or other fibers) that has been specially treated with polyethylene and added with other additives and extruded to form a composite high-strength tensile strip. If the surface has rough embossing, it is a high-strength strip. Reinforced geotechnical tape. From this, the single strips are braided or sandwiched at a certain distance longitudinally and transversely, and their intersection points are welded using special enhanced bonding fusion technology to form a reinforced geogrid.
Product technical features:
. Low strength, small deformation
. Small creep
. Corrosion-resistant, long life: Steel-plastic geogrid is supplemented by plastic material as a protective layer Various additives are used to make it anti-aging, oxidative and resistant to corrosion in harsh environments such as acids, alkalis and salts. Therefore, steel-plastic geogrids can meet the needs of various permanent projects for more than one year and have excellent performance and good dimensional stability.
. The construction is convenient and fast, the cycle is short, and the cost is low: the steel-plastic geogrid is easy to lay, overlap, and position, and it is flat to avoid overlapping and crossing, which can effectively shorten the project cycle and save %-% of the project cost.
Engineering application fields:
Soft soil foundation reinforcement, retaining walls and pavement anti-crack engineering for highways, railways, bridge abutments, approach roads, docks, dams, slag dumps, etc.

The tensile force of the steel-plastic geogrid is borne by warp and weft woven high-strength steel wires, which can produce extremely high tensile modulus under low strain. The synergy of the longitudinal and transverse ribs gives full play to the embedding of the grid into the soil. lock function.
. Various types of gratings can be designed according to project needs using different steel wire diameters or numbers, different rib widths, and different grid mesh sizes to meet the needs of engineering use in different situations.
. Deformation and elongation at break: The steel wires of the longitudinal and transverse ribs of the steel-plastic geogrid are woven into a mesh and the outer wrapping layer is once formed. The steel wires and the outer wrapping layer can coordinately interact with each other. The elongation at break is very low (not greater than %). ). The main stress-bearing unit of steel-plastic geogrid is steel wire with extremely low creep.
. Friction coefficient: During the production process, the plastic surface is treated to suppress rough patterns to enhance the roughness of the grid surface and improve the friction coefficient between the steel-plastic geogrid and the soil.
. Width: The width of steel-plastic geogrid can achieve efficient and economical reinforcement effect.
. Aging and durability: The high-density polyethylene of the steel-plastic geogrid can ensure that it will not be corroded by acids, alkalis, salt solutions or oils at normal temperatures and will not be dissolved by water or invaded by microorganisms. At the same time, the polymer properties of polyethylene are sufficient to resist aging caused by ultraviolet radiation. After the grating is stressed, the vertical and horizontal ribs work together to prevent the nodes from being cracked or damaged. In actual projects, after the filler is compacted, it is not corroded by ultraviolet light and oxygen, so it can fully meet the requirements of permanent project construction.
With the rapid development of the automobile industry, road traffic volume continues to increase, and national and provincial trunk highway traffic tends to be saturated. Especially in recent years, the increase in over-limit, overloaded, and overweight vehicles has resulted in severe overloading of the road surface prematurely within the design life. Pavement diseases have seriously restricted the transportation conditions and traffic capacity of highways, failing to fully play the role of national and provincial arterial roads.
The research on the application of steel-plastic geogrid in highway pavement reconstruction is an internationally leading and domestically pioneered application technology. The research results of this new material and new technology mainly solve the problem of asphalt concrete pavement without a subbase during the reconstruction process. It effectively improves the overall strength and stiffness of the road surface, delays the occurrence of reflective cracks in the road surface, increases the fatigue life of the road surface, and greatly reduces engineering investment.
At present, this internationally and domestically leading technology will be further developed and applied more widely, especially in the reconstruction of roads with one-way heavy-duty traffic.
The projects using this technology that have been counted so far are as follows (including those that have been opened to traffic and those under construction):
) Henan Province Changfu Line (Luojie Highway) Xiangcheng Cigou to Wuyangjie Section Improvement works. Kilometers of secondary roads.
) Henan Province national highway to national highway along the Yellow River connecting line project. km secondary highway.
) Urban road engineering kilometers of secondary roads in Sanzao Town, Zhuhai City, Guangdong Province.
) Shaanxi Province Zhouzhi~Mazhao Provincial Highway Project. Kilometers of secondary highway.
The application of the research results of this project can not only improve the carrying capacity of highways, ensure or extend the service life of highways, and improve the traffic capacity of highways, but also effectively promote the development of the transportation industry and contribute to the stability, health, and sustainability of the macro economy. Provide guarantee for development. Moreover, it can save a large amount of raw materials such as cement and stone, reduce project investment, and reduce maintenance and repair work and expenses. Therefore, the research of this project has good socio-economic and environmental benefits.
Xuchang Municipal Highway Administration Bureau will work with the Provincial Highway Administration Bureau and the Provincial Department of Transportation to organize the research results of the steel-plastic geogrid application project to be further verified and implemented in engineering practice based on summarizing the project research results and the opinions of the appraisal expert group. Improve the transformation of scientific and technological achievements into productivity to meet the needs of the development of heavy-duty transportation.
