1）Dealing with bridgehead jumping
One of the common problems of highways is the bridgehead jumping. The principle of geocells to control bridgehead jumping is to establish a transition section between the concrete bridge and the high-fill subgrade, and use the geocell to limit the lateral displacement of the filling material to form a semi-rigid The interval between the plates and multi-layer plates varies with the soil mass, and the interval is generally 1 m～2 m. The confinement effect of GeoGro's geocell can minimize post-construction settlement.

2）GeoGro's geocell slope protection
GeoGro's geocells can control erosion, and the most applications are slope protection, dams, retaining walls, breakwaters, etc. Its principle is to increase the flow capacity, reduce the erosion of the furrow, prevent the accumulation of water pressure, and eliminate the concentrated erosion. The honeycomb restricting structure can fix the filling material, restrict the water pressure acting on it, thereby improving the flow capacity. The honeycomb wall allows normal drainage, but controls the flow rate in the nest. Like thousands of mini-dams, the concentrated water flow is dispersed into a uniform, soothing thin layer of water flow.

Precautions for GeoGro's geocells during highway construction:
(1) Under the same load and stress level, there is not much difference in the deformation modulus of the top surface of the reinforced cushion with different height cells and different reinforced materials. The top deformation modulus is of little significance. However, the use of GeoGro geocell reinforced structures can effectively reduce the earth pressure on the top surface of the soft soil of the foundation, and has a good spreading stress ability.
(2) When the height of the GeoGro geocell sheet is small, the soil pressure on the top surface of the soft 10 gradually decreases with the increase of the height of the cell sheet; when the cell sheet reaches a certain height (20cm) As the height of the cell sheet continues to increase, the earth pressure on the top surface of the soft soil increases instead.
(3) The use of well-graded coarse particles (good-graded gravel) as the filler in the cell can more effectively improve the overall anti-deformation ability of the entire GeoGro geocell reinforced cushion compared to fine particles f medium sand. The denser the cell cushion filler, the greater the deformation modulus and the smaller the elongation of the H filler itself, the smaller the deformation of the cell sheet under the same stress level, and the higher the degree of foundation bearing capacity can be improved.
(4) On-site settlement observation data show that the use of soil 1 two-cell reinforced foundation can more effectively reduce the settlement of the entire foundation and improve uneven settlement than the use of geogrid-reinforced foundation, and soil GeoGro geocell reinforced cushion It can effectively improve the bearing capacity of the foundation and has a good effect. However, the most human vertical displacement at the bottom of the geocell reinforced embankment is reduced by 11.0% compared to the embankment reinforced by the soil grid. This is somewhat lower than the finite element calculation that can be reduced by about 20.0%. gap.
