In terms of geogrid products, there are still some differences between the enterprises and foreign enterprises in terms of R & D strength and production strength, which leads to the products are not superior to similar foreign products, so it is necessary to increase R & D efforts. Unidirectional geogrid is a kind of high-strength geotechnical material with high molecular polymer as the main raw material, added with certain anti ultraviolet and anti-aging additives, through unidirectional stretching, the originally scattered chain molecules are reoriented and arranged in a linear state, extruded and pressed into thin plates, then punched into regular pore networks, and then stretched longitudinally. In this process, the polymer forms a directional linear state and forms a long elliptical reticular integral structure with uniform distribution and high node strength.

In the process of purchasing steel plastic grille, the geogrid production line equipment needs to select a good manufacturer through regulatory channels. The society is making continuous progress and development. Now the product market is constantly changing. Different brands have different prices. Users should operate through professional channels in the process of purchasing products, so as to create a more favorable guarantee for the actual production development.

What should be paid attention to when laying geogrid?

1. the surface of the lower bearing layer paved with geosynthetics shall be leveled and compacted, and the hard protrusions on the surface shall be removed.

2. the direction with high strength of geosynthetics shall be placed in the main stress direction of embankment.

3. the connection of geosynthetics shall be firm, and the connection strength in the stress direction shall not be lower than the design tensile strength.

4. when laying geosynthetics, they must be tightened, flattened and nailed, and shall be closely pasted with the subgrade surface without folds and distortions.

5. when laying multi-layer geosynthetics, the upper and lower joints shall be staggered alternately, and the staggered distance shall not be less than 0.5m.

6. it is strictly prohibited to roll or walk on Geosynthetics directly by rolling and transportation equipment.

The characteristics of the tensile plastic geogrid: increase the bearing capacity of the subgrade and prolong the service life of the subgrade. Prevent the road (ground) surface from collapsing or cracking, and keep the ground beautiful and tidy. The construction is convenient, saving time and labor, shortening the construction period and reducing the maintenance cost. Prevent cracks in culverts. Strengthen soil slope to prevent water and soil loss. Reduce cushion thickness and save cost. Support the stable greening environment of grass planting mesh mat on the slope. The utility model can replace the metal net and be used for the false roof net in the coal mine.
