In reinforced soil engineering, the steel plastic geogrid must do well in the drainage treatment of the wall surface; do well in foot protection and erosion prevention; set up filtering and drainage methods in the soil, and if necessary, set up geotextile and glass fiber reinforced plastic geogrid, which is a kind of excellent geotechnical composition data used for Pavement Reinforcement, old road reinforcement, strengthening subgrade and soft soil foundation. It has become an irreplaceable data in dealing with reflective cracks of asphalt pavement.

The product is a semi-rigid finished product made of high-strength alkali free glass fiber by warp knitting technology and surface coating treatment. It has high tensile strength, low elongation and high temperature resistance, low cold resistance, anti-aging and corrosion resistance. It is widely used in asphalt pavement, cement road surface and roadbed enhancement, railway subgrade, dam embankment revetment, airport runway, sand control and sand control projects.

The data of steel plastic geogrid can not only improve the shear strength, deformation and water permeability of soil, but also improve the dynamic characteristics of foundation. Therefore, in many slope, embankment, dam, abutment and other projects, geotechnical composition data are used for reinforcement processing, and the steel plastic geogrid as reinforcement data plays an outstanding role in engineering processing.

It can be used to reduce the uneven settlement and overall settlement of subgrade, restrain the lateral displacement, and avoid the jumping of abutment. Compared with the common subgrade treatment methods, the geotechnical composition data has the advantages of low cost, simple skills, short construction period, good practicability for all kinds of foundation, so it has been widely used in the project.

Subgrade refers to the strip structure built as the pavement foundation according to the route location and certain technical requirements. Subgrade is a linear structure built with soil or stone. It bears its own weight of rock and soil, the gravity of the road surface, and the driving load transmitted from the road surface, which is an important part of the whole road structure.

The high-strength steel plastic geogrid is composed of high-strength steel wire wrapped with polyethylene to form a vertical and horizontal steel plastic composite rib as a force element subjected to 7a6869616fe59b9ee7ad9431333366306539. After the special processing treatment such as ultrasonic wave at the joint, the grid like sheet with high tensile strength and good integrity is formed. In the application, the grid like sheet and the soil are jointly stressed to play a strong interlocking role, so as to maintain good integrity Body stability.

1. Steel plastic composite material is adopted, which has small deformation and high tensile strength, and overcomes the defects of large deformation and creep of plastic grid.

2. With the special node treatment technology, the longitudinal and transverse ribs have strong cooperative working ability, which can give full play to the reinforcement effect of the grid.

3、The width can reach 10m, which can reduce overlapping, save materials and simplify construction.

4. The unique material formula and production process make the product fully meet the industry standards and design requirements after 100 freeze-thaw cycles, and meet the requirements of frost resistance in the north.

It is suitable for reinforced earth retaining wall, abutment, slope and subgrade reinforcement to improve the bearing capacity of soft foundation and resist the formation of soil fracture surface.

High strength geogrid is widely used in soft foundation treatment and treatment of uneven settlement of subgrade due to its characteristics of large tensile strength and small deformation, especially in the treatment of uneven settlement of new and old subgrade. The effect of steel plastic grid instead of plastic grid treatment is better, and it is the preferred material for treatment of uneven settlement of subgrade. In soft soil foundation, steel plastic composite geogrid is used for reinforcement, and its network structure is conducive to drainage of soft soil foundation; under embankment filling load, water in soft soil seeps out, which promotes consolidation of soft soil and increases bearing capacity of soil foundation. Soft soil foundation and steel plastic composite geogrid work together to form a interlocking system. When the vehicle is loaded, the vertical stress on both sides increases, so that the vertical stress of the base tends to be uniform.
