The glass fiber geogrid roll is made of glass fiber alkali-free and twist-free roving as the main raw material. It is a mesh structure material made by a certain weaving process. In order to protect the glass fiber and improve the overall performance, a new type is formed by a special coating process. Excellent geotechnical substrate.
Characteristic of Biaxial geogrid fiberglass mesh fabric roll
(1) High tensile strength and low elongation--Glass fiber geogrid is made of glass fiber, which has high resistance to deformation, and the elongation at break is less than 3%.
(2) No long-term creep--As a reinforcing material, it is extremely important to have the ability to resist deformation under long-term load, that is, creep resistance. The glass fiber will not creep, which ensures that the product can maintain long-term performance.
(3) Thermal stability-the melting temperature of glass fiber is above 1000°C, which ensures the thermal stability of the glass fiber geogrid during paving operations.
(4) Compatibility with asphalt mixing--The material coated in the post-treatment process of the glass fiber geogrid is designed for asphalt mixture, and each fiber is fully coated, which has a high correlation with asphalt. Capacitive, thus ensuring that the glass fiber geogrid is not isolated from the asphalt mixture in the asphalt layer, but is firmly combined.
(5) Physical and chemical stability-After coating with a special post-treatment agent, the glass fiber geogrid can resist all kinds of physical abrasion and chemical erosion, and also resist biological erosion and climate change, ensuring its performance is not affected.
(6) Aggregate interlocking and restriction--Because the glass fiber geogrid is a mesh structure, the aggregate in the asphalt concrete can penetrate through it, thus forming a mechanical interlocking. This restriction hinders the movement of the aggregate, so that the asphalt mixture can achieve a better compaction state, higher load-bearing capacity, better load transfer performance and smaller deformation under load.
Folding engineering function
1. High strength, low creep, adapt to various environmental soils, and can fully meet the use of tall retaining walls in high-grade highways.
2. It can effectively improve the interlocking and occlusion 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 the traditional grid, it has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform holes, convenient construction and long service life.
4. It is more suitable for deep-sea operations and embankment reinforcement, and fundamentally solves the technical problems of low strength, poor corrosion resistance, and short service life caused by long-term seawater erosion caused by other materials for stone cages.
5. It can effectively avoid construction damage caused by being crushed and damaged by machinery during the construction process
Folding application field
1. Suitable for all kinds of roads, railways and airports to enhance roadbed enhancement. 2. It is suitable for foundation reinforcement of permanent bearing such as large parking lots and terminal freight yards.
3. Suitable for slope protection of railway and highway.
4. Applicable culvert enhancement.
5. It is suitable for the secondary reinforcement of the soil slope reinforced by the unidirectional stretching geogrid to further strengthen the soil slope and prevent soil erosion.
6. Reinforcement of mines and tunnels.
