Geogrid Is a kind of Geosynthetics Compared with other geosynthetics, it has Different Performance and efficacy. Geogrid is commonly used as Reinforced soil Structural reinforcement or composite reinforcement, etc. The geogrid is divided into plastic geogrid , steel plastic geogrid Glass fiber geogrid And polyester Polyester geogrid Four categories.
Steel plastic geogrid This product is made of steel wire too Treatment, with polyethylene (PE), and add other additives, and extrude it into a composite tension belt with rough embossing on the surface, then it is a reinforced geotextile belt. This single strip is woven or clamped at a certain distance longitudinally and transversely, and is formed by welding its junction points with the fusion welding technology of enhanced bonding. It is a reinforced steel plastic geogrid
1、 Steel plastic grille brief introduction ：
1. High strength, low creep, and adaptability to various environmental soils, which can completely meet the requirements of highway retaining Soil Wall usage.
2. Can lift rise The interlocking and interlocking action of the reinforced bearing surface can greatly enhance the bearing capacity of the foundation, restrain the lateral displacement of the soil, and enhance the stability of the foundation.
3. Compared with the traditional grid, it has large strength, strong bearing capacity, large friction coefficient, uniform holes, convenient construction, long service life, etc.
4. It is suitable for deep sea operation and bank reinforcement, and fundamentally solves the technical problems of low strength and short service life of gabions made of other materials due to long-term seawater erosion.
5. Avoidable too Construction damage caused by rolling and destruction of machines and tools during construction.
2、 How to construct steel plastic grille:
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 section length, the overall paving quality shall be checked, and then the next section shall be paved. When the next section is paved, the grid and the grid shall overlap one grid net distance as the lap length, and continue to pave the next section in the forward direction after being fixed with binding wire. By analogy, the operation requirements are the same as above.
