At present, the geotechnical test materials commonly used in the construction of engineering projects in China have the characteristics of uniform overall economic structure, high tensile strength, high tensile modulus, good torsion resistance, low strain, and good creep resistance. The main technology is applied in the fields of industry, agriculture, metallurgy, construction, water conservancy, port, municipal administration, railway, highway, airport, coal mine and other fields The reinforced protection of wall, slope and embankment and the treatment of soft soil foundation can provide service quality management support for engineering construction enterprises, prolong the service life of available network, and become the materials in the design and construction process of China's best environment engineering. The polymer mesh with square or rectangular shape formed by two-way geogrid in china stretching can be divided into unidirectional tension and biaxial tension according to the different tensile directions when they are manufactured. It is to punch holes on the extruded polymer sheet (the raw materials are mostly polypropylene or high-density polyethylene), and then conduct directional stretching under heating conditions. Glass fiber geogrid is a new type of excellent geotechnical base material for strengthening road surface and subgrade. The product is made of alkali free glass fiber filament as the main raw material, woven by unique warp knitting weaving technology and coated with special rubber. Using polypropylene plastic (PP) and special additives, the flame retardant and antistatic plastic belt for underground coal mine has been successfully developed by using plastic directional drawing, flame retardant and antistatic technology. Through the inspection of national quality inspection department, the mining plastic mesh fully meets the requirements and obtains the production license. Common geotechnical materials include geotextile, geomembrane, geogrid, geogrid, two-way geogrid in china, plastic blind ditch, flexible permeable pipe and other types. They all have more diversified specifications and models, which are suitable for different system engineering data types and meet the development needs of information engineering.

Biaxial is usually based on polypropylene, high-density polyethylene as raw material, especially extrusion, transverse in the production process / first longitudinal stretching, and geogrid formation. It may be necessary to reduce the filling of the structure, uniform load distribution, high modulus and tensile strength with biaxial tension, high resistance and endurance to mechanical failure. The biaxial shallow additional stability of the slope of reinforced embankment depends on the complete bite force and friction force of soil and two-way geogrid in china, which requires that the reinforcement material must have sufficient strength and length to produce resistance and solid grip to ensure slope stability. This depends on enhancing embankment load strength, packing performance, fill slope stability, tensile strength, geogrid reinforcement, spacing, and length from that layer.

Therefore, we can see that if the enterprise wants to continuously improve the stability of reinforced soil embankment and slope, it has a very important relationship with the selection of two-way geogrid in china. The majority of constructors must pay attention to the use of two-way geogrid in china, and select the geotechnical materials suitable for the construction of the project, so as to avoid some unnecessary influence in the later construction.
