1. Noun concept:
Geotechnical grid room:
Geogrid is a new type of high-strength geosynthetic material that is currently popular both domestically and internationally. It is a three-dimensional mesh structure formed by high-strength welding of reinforced HDPE sheet material. It has flexible expansion and contraction, can be transported and stacked, and can be stretched into a mesh during construction, filled with loose materials such as soil, gravel, and concrete, forming a structure with strong lateral restraint and high stiffness. It has the characteristics of light material, wear resistance, stable chemical properties, resistance to light and oxygen aging, acid and alkali resistance, etc. Due to its high lateral restraint and anti slip, anti deformation, effective enhancement of roadbed bearing capacity and load dispersion, it is currently widely used in cushion layers, stable railway subgrades, stable road soft foundation treatment, support structures for pipelines and sewers, mixed retaining walls to prevent landslides and bear gravity, desert, beach and riverbed, riverbank management, etc.
Geogrid:
Geogrid is a two-dimensional mesh or three-dimensional mesh screen with a certain height made of high molecular weight polymers such as polypropylene and polyvinyl chloride through thermoplastic or molding. It has the characteristics of high strength, strong bearing capacity, small deformation, low creep, corrosion resistance, high friction coefficient, long service life, convenient and fast construction, short cycle, and low cost. Widely used in soft soil foundation reinforcement, retaining walls, and pavement crack resistance engineering for highways, railways, bridge piers, approach roads, docks, dams, slag yards, and other fields.
2. Common points:
All are polymer composite materials; And it has the characteristics of high strength, strong bearing capacity, small deformation, small creep, corrosion resistance, high friction coefficient, long service life, and convenient and fast construction; They are all used for soft soil foundation reinforcement, retaining walls, and pavement crack resistance engineering in highways, railways, bridge piers, approach roads, docks, dams, slag yards, and other fields.
3. Differences:
1) Shape and structure: The geogrid is a three-dimensional mesh structure, and the geogrid is a two-dimensional mesh or a three-dimensional mesh grid structure with a certain height
2) Lateral restriction and stiffness: Geogrid cells are superior to geogrids
3) Bearing capacity and load dispersion effect: Geogrid cells are superior to geogrids
4) Anti slip and anti deformation ability: Geogrid cells are superior to geogrids
4. Economic comparison:
In terms of engineering usage cost, geogrids are slightly higher than geogrids.
