The full name of steel plastic grille is steel plastic composite Geogrid 。 It is made of steel wire (or other Fiber), via too Processing, with poly ethylene ( PE), And add Other additives It is a reinforced geotextile belt if it is extruded into a composite tension belt with rough embossing on the surface. This single strip is formed by welding its junction points with the fusion welding technology of bonding, which is compiled or clamped at a certain distance longitudinally and transversely. It is a reinforced geogrid.
Steel plastic geogrid is widely used in engineering and plays an important role :
The steel plastic grille is applicable to all kinds of embankment and subgrade reinforcement, slope protection, tunnel wall reinforcement, large airport, parking lot, wharf freight yard and other bearing foundation reinforcement.
1. Steel plastic grille is used to increase the bearing capacity of road (ground) foundation and extend the service life of road (ground) foundation.
2. Steel plastic grille is used to prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy.
3. Steel plastic grille is used to facilitate construction, save time and labor, shorten construction period and reduce maintenance costs.
4. Steel plastic grille is used to prevent cracks in culvert.
5. Steel plastic grille is used to strengthen soil slope and prevent water and soil loss.
6. Steel plastic grille is used to reduce the thickness of cushion layer and save cost.
7. Steel plastic grille is used to support the stability of grass planting mat on the slope for greening environment.
Construction precautions
1. The paving surface of the geogrid shall be relatively flat. After the paving layer is accepted, in order to prevent longitudinal deflection, white lines or hanging lines shall be drawn on the paving layer according to the width, and then the paving can be started, and the end of the geogrid shall be fixed with U-nails (4 nails per meter of width, fixed at an even distance).
2. After fixing the end of the grid, use the paver or manual method to slowly pull the grid forward and straighten it manually every 10 meters until one roll of grid is paved, and then pave the next roll. The operation is the same as before.
3. Overlay: take the roll length as the length of the paved section. After the grid is paved within the length of the section, check the overall paving quality, and then pave the next section.
