What is the difference between a geocell and a geogrid?

Geocells and geogrids belong to a new type of building materials widely used in roadbed, slope protection and other engineering projects, and both have the characteristics of high compressive strength, strong bearing capacity, small deformation, corrosion resistance, high friction resistance, long service life, time-saving and labor-saving in engineering and construction, short cycle time, and low cost.

1 Geocell and geogrid essential difference

From the professional production point of view, geocell is strengthened by the HDPE sheet of raw materials, by the high super strength welding and welding to produce a three-dimensional mesh structure chamber structure. Geogrid is made of polypropylene, polyethylene and other polymer materials such as polymer by thermoplastic or compression molding into a two-dimensional grid pattern or with a certain height to width ratio of the three-dimensional grid pattern screen grid. Both are lightweight polymer materials made of polymer materials, are widely used in pavement capital construction and a series of soft foundation treatment foundation reinforcement, retaining walls and ground crack-resistant fiber engineering projects and other industries.

2 Comprehensive difference

• From the structural mechanics point of view brand image, geocell is three-dimensional stiffening geogrid is a planogram stiffening.

• From the look of the structure, geocell for three-dimensional mesh structure chamber structure geogrid for two-dimensional grid shape or with a certain height to width ratio of three-dimensional three-dimensional mesh screen grid structure, and the geogrid is a two-dimensional grid structure.

• From the comprehensive ability to compare, side limit and bending stiffness: geocell is better than geogrid; bearing capacity and decentralized load effect: geocell is better than geogrid; ground anti-slip, anti-deformation work ability: geocell is better than geogrid

• From the economic development cost fee, both are inexpensive, geocell is slightly higher than geogrid.

3 Geocell characteristics

• It can be large or small, transportation can be folded, engineering construction can be pre-stressed tensioned into a mesh structure, fill the soil, gravel, soil and other loose raw materials, composed of strong lateral limit and large bending stiffness.

• Material is light, anti-wear, smooth organic chemical properties, resistance to light and oxygen embrittlement, corrosion resistance, applicable to different soil layers and deserts and other soil conditions.

• Higher side limit and ground anti-skid, anti-deformation, reasonable to improve the bearing capacity of roadbed engineering and decentralized load effectiveness.

• It can be big or small, and the transportation body is small; it is convenient to connect and the project construction speed is faster.

4 Geocell main use

• It is used for solid road and railroad line foundation project.

• It is used to bear the load force of the river embankment and shallow water river training project.

• It is used to avoid landslide and mixed teaching retaining wall which is subject to load force.

• When encountering soft roadbed. Selection of geocells can greatly ease the engineering construction labor efficiency, reduce the roadbed engineering thin and thick engineering construction faster, good characteristics, greatly reducing the project budget.

5 Conclusion

Geogrid is a two-dimensional grid figure-like grating made of polypropylene, high-pressure polyethylene and other polymer materials polymers by thermoplastic or compression molding, when used as a construction professional application, it is called a geogrid. Geocell structural reinforcement of roadbed is a footing type of sand structure reinforcement, it does not have to change the filler granular material composition and interconnection and other characteristics of the base wood. Geocell is mainly through the mutual practical effect with the common two to arrive at the purpose of structural reinforcement, the mutual practical effect mainly includes three levels: geocell side constraints of the practical effect, geocell net effect, and its geocell contradiction of the practical effect.
