What is the main function of geogrid?

1. If used in road construction, geogrids can not only help the foundation increase its bearing capacity and effectively extend the service life of the foundation, but also effectively prevent cracking or collapse of the ground, thereby ensuring that the ground can remain beautiful and flat.

2. If used in culvert construction, geogrids can effectively prevent cracks in the culvert and prevent collapse of the culvert. If used in slope construction, geogrids can effectively prevent soil loss on the slope.

What should be paid attention to during geogrid construction

1. When storing and laying geogrids, long-term exposure to the sun should be avoided, otherwise the performance is prone to deterioration. When laying geogrids in the vertical direction, the overlap position should be constructed according to the requirements of the construction drawings, and must be firmly connected. At the same time, the strength of the connection position in the force direction must be greater than the tensile strength of the material itself, and the overlapped splicing position cannot be less than 20 centimeters.

2. The construction quality of the geogrid must comply with the construction requirements specified in the design and construction drawings. During the construction process, wrinkles, overlaps, twists, etc. must not occur, and the geogrid must also be kept taut so that it can be evenly stressed. If it is tightened manually, the geogrid must be close to the ground, the force must be even, the surface must be flat, and nails must be used to fix the geogrid to avoid displacement.
