Polyester geogrid is used to reinforce the soft soil subgrade of highway, railway, municipal road and other roads, which can effectively improve the strength of the subgrade and delay the reflection cracks of the road. Polyester geogrid used in highway can strengthen the soft soil foundation, enhance its protective ability, and improve the bearing capacity and stability of the foundation. Polyester geogrid can not only make the concrete form a dense surface, but also improve the apparent quality of concrete.
Polyester geogrid used in highway is used for reinforcement of embankment slope and retaining wall to enhance the overall strength, and for reinforcement of highway, railway, water conservancy and other soft soil foundation. But after use, it can achieve the effect that general materials can not achieve. Usually in the situation of diffuse humidity, high-strength corrosion-resistant use, added its service life, soaked in water for a long time, will not affect its use effect. The utilization rate of geotextile has been very high in the construction engineering. With high-strength use value, the application of polyester geogrid used in highway, no matter in dry condition or in wet condition, polyester geogrid has good tensile property, even if it is pulled by gravity, it will not break. The polyester geogrid used in highway has high corrosion resistance and extremely durable
When polyester geogrid is used in the plastic surface treatment of highway production process, ribs are pressed into rough patterns to enhance the friction coefficient between the grid and the soil. The longitudinal and transverse strength reaches 20KN / m-150kn, while the elongation at break is not higher than 3%. The width is 2-8m, reducing construction overlap, reducing material and construction cost. Mainly used for: highway, railway, dam, water conservancy, tunnel, engineering reinforcement. Polyester geogrid used in highway to be wrapped into high-strength strips by high-density polyethylene, which are at right angles to the plane longitude and latitude. The geosynthetics formed by ultrasonic welding are analogized in turn. According to the needs of the project, different mesh diameters and the number of steel wires are used to change the tensile strength of the steel belt. After the road surface is ready, lay the glass fiber geogrid on the road surface with the adhesive facing downward. Whether the grid is laid mechanically or manually, it is pressurized with a brush and then pressurized with a roller with pneumatic tires, so as to obtain better bonding effect. Asphalt concrete pavement materials shall be laid with general equipment and process immediately after laying.
Polyester geogrid is suitable for all kinds of embankment and subgrade reinforcement, slope protection, tunnel wall reinforcement. Foundation reinforcement for permanent bearing of large airport, parking lot, wharf yard, etc.
Polyester geogrid is used to increase the bearing capacity of Road (ground) foundation and extend the service life of long road (ground) foundation. Polyester geogrid is used to prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy. Polyester geogrid is used for construction convenience, time saving, labor saving, shortening construction period and reducing maintenance cost. Polyester geogrid is used to prevent cracks in culverts. Polyester geogrid is used to strengthen soil slope and prevent soil erosion. Polyester geogrid is used to reduce cushion thickness and cost. Polyester geogrid is used to support the stable greening environment of grass planting mat on the slope. The polyester geogrid used in highway can effectively prevent the transmission of seismic force and play an important role in strengthening the seismic stiffness, strength and stability of embankment.
