After the steel plastic geogrid is adopted, the highway subgrade is stronger and the service life is longer. At present, the number of subgrade is very large, and the use of highway and railway is also very large. At present, the products of geogrid are relatively complete, including reinforced plastic geogrid for subgrade reinforcement and glass fiber geogrid for highway pavement.

The greening of convex geogrid and plastic tensile geogrid will also be used to strengthen the geogrid, which is used to make plants climb better. Because some construction units use steel wire mesh construction before construction, the cost is very high, not afraid of wind and rain, the use of plastic geogrid, greatly reduce the cost, and the service life is longer, do not need frequent maintenance workers, reduce all aspects of the cost.

In addition, some engineering projects are used to strengthen the geogrid with high tensile strength, such as the cheaper glass fiber geogrid used in municipal roads and highways, and the biaxial tensile plastic geogrid is generally used in subgrade construction. In the infrastructure construction of some power plants.

It also uses large-scale high-strength biaxial tensile plastic geogrid for reinforcement. Because of its high strength, high tensile strength, large plate thickness and high cost, it is not commonly used. The subgrade and pavement strengthen the geogrid and have a longer service life, so as to avoid some routine maintenance, especially in the cold winter area, reduce the asphalt pavement cracks, increase the resistance of estrus, and the service life is better than the pavement not suitable for geogrid.

Key points of construction method of steel plastic geogrid

1. The laying surface of the geogrid shall be relatively flat. After the laying layer passes the acceptance, in order to prevent the longitudinal deflection, first draw a white line or hanging line on the laying layer according to the width, and then start the laying, and then fix the end of the geogrid with U-shaped nails (4 nails per meter of width, fixed at a uniform distance).

2. After fixing the end of the grid, use the paver or manual method to slowly pull the grid forward, and manually straighten it once every 10 meters until one roll of the grid is paved, and then pave the next roll. The operation is the same as before.

3. Joint laying: take the roll length as the length of laying section. After the grating laying section is full, check the laying quality as a whole, and then lay the next section.

When the next section is laid, the net distance between the grid and the grid overlaps by one grid as the lap length, and after being fixed with binding wire, continue to pave two sections in the forward direction. By analogy, the operation requirements are the same as before.
