Geogrid is a kind of main geosynthetics. Compared with other geosynthetics, it has unique performance and efficacy. It is often used as reinforcement of reinforced soil structure or composite material.

In the manufacture of plastic geogrid, the polymer will rearrange and orient with the heating extension process, which strengthens the bonding force between molecular chains and achieves the purpose of improving its strength. Its elongation is only 10% ~ 15% of the original plate. If carbon black and other anti-aging materials are added to the geogrid, it can have better durability of acid resistance, alkali resistance, corrosion resistance and anti-aging.

What are the functions of geogrid introduced by the equipment manufacturer of geogrid production line

The geogrid is applicable to the reinforcement of various embankments, subgrade, slope protection and tunnel wall. Permanent bearing foundation reinforcement for large airports, parking lots, wharfs and freight yards. Geogrid is used to increase the bearing capacity of subgrade and prolong the service life of subgrade. The geogrid is used to prevent the collapse or crack of the road (ground) surface and keep the ground beautiful and tidy. The geogrid is used for convenient construction, saving time and labor, shortening the construction period and reducing the maintenance cost. Geogrids are used to prevent cracks in culverts. The geogrid is used to strengthen the soil slope and prevent water and soil loss. The geogrid is used to reduce the cushion thickness and save the cost. The geogrid is used to support the stability and greening environment of grass planting mesh mat on the slope. Geogrid can effectively isolate the transmission of seismic force, and plays an important role in enhancing the seismic stiffness, strength and stability of embankment. The successful application of geogrid is expected to reduce various embankment diseases common in high-intensity seismic areas and improve the ability of earthquake resistance and disaster reduction of roads.

The paving surface of the geogrid shall be relatively flat. After the paving layer passes the acceptance, in order to prevent longitudinal deflection, the paving can be started by drawing a white line or hanging a line on the paving layer according to the width, and then fixing the end of the grid with iron nails (8 nails per meter wide, fixed at an even distance). After fixing the end of the grid, use the paver to slowly move the grid.

The paving shall be pulled forward, and the manual tightening and straightening shall be carried out once every 10m long until one roll of grid is paved, and then the next roll shall be paved. The operation is the same as before. After one roll is paved, the 6t-10t road roller can be used to roll it from the starting point to the forward direction.
