Geocells are an important part of the slope protection system, and the geocell binding force is an important factor for the geocell to participate in the formation of the protection system. Giving full play to the effectiveness of the geocell binding force is essential to improving the strength and stability of the road slope protection system, and the factors affecting the geocell binding force are mainly reflected in three aspects.
1. Specification size factor
For the effect of slope protection, the slope slope, geocell sheet height, geocell welding distance and many other factors, for the slope angle of the project, choose the sheet height is larger and welding distance is smaller finished products, for the slope strength of the improvement is more obvious, but also to better achieve the combination of geocell and planting grass, in the steep slope using high specification geocell more able to make it The use of high-specification geocells on steep slopes can make them work together with vegetation to reduce soil erosion and improve the poor ecological environment.
2. Soft and hard roadbed factors
The use of geocells on soft soil roadbeds such as sandy roads can play a very obvious role in the three-dimensional binding force of the grid, as the sandy soil has a high degree of mobility, the damage to the rigidity of the road base is greater, we must choose a geocell with higher sheet strength, higher sheet height and higher sheet friction, in order to fully limit the mobility of the sandy soil soft base. The geocell is a strong and stable material. And in the plain area more solid and stable grass-roots level, because the grass-roots level itself is relatively high rigidity, mobility is relatively poor, you can choose the sheet height of smaller geocell for construction.
3、Construction method is correct or not
The correct construction method largely determines whether the geocell binding force can be effectively played after completion. Geocells in retaining walls and other projects should take the correct superimposed construction method, which can not only play a greening role, but also form a horizontal binding force, plus the effect of its layers superimposed, which can effectively strengthen the retaining wall. The construction on the slope, often from the top of the slope to the slope to unfold the construction, and the horizontal plane is a certain angle, strengthen the slope paving process of fixing, in order to avoid the later spraying when the geocell will not be a large area of pulling and pulling caused by the cell unit unfolding incomplete, and the cell unit unfolding incomplete, is an important factor affecting the geocell binding force to play.
In summary, the size of the specification, the degree of softness of the roadbed, the correct construction method or not for the geocell binding force, is the crucial three important factors, only in strict accordance with the engineering foundation conditions to choose the appropriate geocell, in order to ensure the safe and effective completion of the project, and give full play to the geocell binding force.
