Geocell is a new type of synthetic material, which is mainly used to improve the bearing capacity of roadbed, prevent landslides and load-bearing hybrid retaining walls. In the process of widening and laying geocells on new roads, it has the following important significance:
1. Improve the bearing capacity of roadbed
Geocells can effectively enhance the bearing capacity of the roadbed and disperse the load. It provides high lateral restraint and anti-skid properties, allowing the roadbed to better withstand vehicle loads and other external pressures, thereby extending the life of the roadbed.
2. Reduce uneven settlement
Geocells can be stretched into a mesh during construction and filled with loose materials to form a structure with strong lateral restraint and high stiffness. This structure can effectively prevent soil deformation and improve soil stability. At the same time, it can also reduce the uneven settlement between the roadbed and the structure, and alleviate the early impact damage of the bridge deck caused by the “abutment jump” disease.
3. Reduce project costs
Using geocells, materials can be obtained locally or nearby, and even materials that cannot be used under normal circumstances can be used, thus significantly reducing material purchase costs and transportation costs. In addition, it can reduce the thickness of the cushion layer and save costs. These characteristics of geocells make them play an important role in reducing project costs.
4. Environmental protection and sustainability
The use of geocells not only improves the stability of the road, but also has certain environmental protection value. For example, in slope protection, geocells can be used in slope protection structures and can be filled with planting soil, on which grass and shrubs can be planted to achieve a greening effect. This construction solution is considered green and sustainable .
5. Improvement of construction efficiency
The geocell can be freely expanded and retracted to ensure quick connection, which greatly improves the efficiency of construction. At the same time, it can be easily transported and stored after folding to adapt to different engineering needs.
In summary, the widening and laying of geocells on new roads can not only improve the stability and load-bearing capacity of the road, reduce uneven settlement, and reduce the project cost, but also have the advantages of environmental protection and high construction efficiency. Therefore, it is a technical means worthy of promotion and application in modern road construction.
