What is the difference between a geocell and a geogrid?

Geocell is a new type of high-strength geosynthetic material that is popular at home and abroad. It is a three-dimensional mesh cell structure formed by reinforced HDPE sheet material through high-strength welding. It can be expanded and retracted freely, can be retracted during transportation, and can be stretched into a mesh during construction. After filling in loose materials such as soil, gravel, and concrete, it forms a structure with strong lateral restraint and high rigidity. It has the characteristics of light material, wear resistance, stable chemical properties, light and oxygen aging resistance, acid and alkali resistance, etc. Due to its high lateral limit and anti-slip, anti-deformation, effectively enhancing the bearing capacity of the subgrade and dispersing the load, it is currently widely used in: cushion, stable railway subgrade, stable highway soft ground treatment, pipeline and sewers. Support structure, mixed retaining wall to prevent landslides and load gravity, desert, beach and riverbed, river bank management, etc.

What is the difference between a geocell and a geogrid

 Geogrid is a two-dimensional grid or a three-dimensional grid screen with a certain height, which is made of polypropylene, polyvinyl chloride and other macromolecular polymers by thermoplastic or molding. It has the characteristics of high strength, strong bearing capacity, small deformation, small creep, corrosion resistance, large friction coefficient, long life, convenient and fast construction, short cycle and low cost. It is widely used in the fields of soft soil foundation reinforcement, retaining wall and pavement crack resistance engineering of highways, railways, bridge abutments, approach roads, docks, dams, slag yards, etc.

Common ground:

 They are all polymer composite materials; and have the characteristics of high strength, strong bearing capacity, small deformation, small creep, corrosion resistance, large friction coefficient, long service life, and convenient and quick construction; they are all used in highways, railways, bridge abutments, Approach roads, docks, dams, slag yards and other fields of soft soil foundation reinforcement, retaining walls and pavement crack resistance engineering.

Difference:

1) Shape structure: The geocell is a three-dimensional grid cell structure, and the geogrid is a two-dimensional grid or a three-dimensional three-dimensional grid screen grid structure with a certain height.

2) Lateral restraint and stiffness: Geocells are better than geogrids

3) Bearing capacity and distributed load effect: geocell is better than geogrid

4) Anti-skid, anti-deformation ability: geocell is better than geogrid

Economic comparison:

In terms of the use cost of the project: the geocell is slightly higher than the geogrid.What is the difference between a geocell and a geogrid?
