What is the main function of geogrids

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

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

What aspects should be paid attention to during the construction of geogrids

1. When storing and laying geogrids, long-term exposure to sunlight should be avoided, otherwise their performance may deteriorate. When laying geogrids in the vertical direction, the overlapping 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 stress direction must be higher than the tensile strength of the material itself. The overlapping 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, wrinkling, overlapping, twisting, and other phenomena must not occur. The geogrid also needs to be kept in a tight state to ensure that it can withstand uniform force. If it is manually tightened, the geogrid must be tightly attached to the ground and the force must be uniform, The surface must be flat, and it is also necessary to use insertion nails to fix the geogrid to avoid displacement.
