Geocell is an important part of the slope protection system, and the restraint force of the geocell is an important factor for the formation of the protection system by the intervention of the geocell. Giving full play to the effectiveness of the restraint force of the geocell is important for improving the protection system of the road slope. Strength and stability are of the utmost importance, so today we will talk about the three factors that give full play to the binding force of the geocell.

1. Size factor

For the effect of slope protection, it is necessary to summarize many factors such as the slope of the slope, the height of the geocell sheet, and the welding distance of the geocell. Finished products with a smaller welding distance have more obvious improvement in slope strength, and can better realize the combination of geocells and planting grass. The application of high-standard geocells on steep slopes can make them work together with vegetation to reduce soil erosion, improve the originally harsh ecological environment.

2. Factors of hardness and softness of roadbed

In the construction of road subgrade, it is necessary to fully consider the quality of the underlying conditions. The application of geocells on soft soil subgrades such as sand roads can significantly exert the three-dimensional binding force of the grid. Due to the high mobility of sand, for the destruction of the rigidity of the lower layer of the road, it is necessary to select a geocell with high sheet strength, high sheet height, and large sheet friction, so as to fully limit the mobility of the sand soft foundation. On the lower layer, which is relatively firm and stable in the plain area, due to the relatively high rigidity and poor mobility of the lower layer itself, a geocell with a smaller sheet height can be selected for construction.

3. Whether the construction method is correct or not

Whether the construction method is correct or not determines to a large extent whether the binding force of the geocell can be effectively exerted after completion. The geocell should adopt the correct superimposed construction method in projects such as retaining walls, which can not only play a greening role, but also can formation of horizontal binding force, coupled with its layer-by-layer effect, can effectively strengthen the strength of the retaining wall. In the construction on the slope, the construction is often carried out from the top of the slope to the bottom of the slope, which is at a certain angle to the horizontal plane. Strengthening the fixation during the slope paving process can prevent the geocell from being pulled in a large area during the later spraying. The incomplete deployment of cell units is an important factor that affects the binding force of geocells.

To sum up, the size, the softness and hardness of the subgrade, and the correctness of the construction method are the three most important factors for the binding force of the geocell. In order to ensure tsafe and effective completion of the project, and give full play to the binding force of the geocell,we should pay attention to those three factors.
