Are geotextiles and geogrids the same?-GD Geosynthetics

Both geotextiles and geogrids belong to geotechnical materials, but there are essential differences in usage and functions. The functions of geotextiles mainly include isolation, filtration, drainage, protection, etc., while geogrids mainly play the role of stabilizing the roadbed and prolonging the life of the road. The two are not only different in function, but also have a big gap in appearance.

Geotextiles of various colors First, the difference between geotextile and geogrid

Geogrids are mainly divided into steel-plastic geogrids, fiberglass geogrids and polyester warp-knitted polyester geogrids, etc. It is a high-strength geotechnical material with polypropylene as the main raw material. , transverse biaxially stretched into a nearly square network structure. It is mainly used in various roadbed and pavement reinforcement projects such as highways, railways, airports, etc., and can also be used in the support and reinforcement of culverts, mines, roadways, etc. It is a widely used geosynthetic material at present.

Geotextile, also known as geotextile, is a geotechnical test composite material made of man-made fibers through knitted or knitted olefin metathesis. Its key is divided into non-woven geotextiles and woven geotextiles. It has extraordinary functions of filtration, drainage, protection, reinforcement, waterproof layer, safety protection, etc. It has the advantages of light weight, high compressive strength, good infiltration characteristics, heat resistance, refrigeration resistance, aging resistance, corrosion resistance, etc. In water conservancy projects, river embankments, roads, airports, engineering buildings, environmental protection and other engineering projects, it has the functions of filtration, drainage, protection, safety protection, and structural reinforcement.

geotextile Second, the role of geotextiles

1. Protection. Non-woven geotextiles with different process properties (particle size, distribution, mortar consistency, relative density, etc.) are solved by the polyester polyester staple fiber needle method. Raw materials (such as soil and sand, soil and concrete, etc.) are protected. It ensures that two or more kinds of raw materials do not flow out and do not mix, maintain raw materials, integrate structure and function, and improve structural bearing capacity.

2. Filtration (reverse filter) When introducing water into coarse soil, use polyester staple fiber weave needle non-woven geotextile to make the water have excellent air permeability and water absorption. Coarse-grained soil, fine sand, fine sand and gravel, etc., should be properly retained to maintain the stability of the soil and water engineering project.

3. Drainage pipes. Polyester polyester staple fiber needle type non-woven geotextile has good water solubility and can create a safe channel for drainage pipes inside the sandy soil, making the sandy soil structure more introverted. The remaining liquid and gas flow straight out.

4. Improve the bones. The use of polyester staple fiber needle non-woven geotextiles improves the tensile strength and anti-deformation performance of the non-woven geotextiles, improves the reliability of housing construction, and improves the quality of the soil layer.

5. Maintenance. When rinsing the sandy soil, the flowing water reasonably spreads the stress, transmits or dissolves the earth, so as to avoid the sandy soil from being damaged by external force, thereby maintaining the soil layer.

6. Anti-stab. The anti-seepage geomembrane is combined with each other to make a composite moisture-proof and waterproof layer raw material, which has the function of anti-puncture.

7. The role of geogrid

8. Improve the roadbed project, reasonably allocate the external diffusion load, improve the reliability of the roadbed project, improve the bearing capacity, and increase the service life of the roadbed project;

9. Can bear a large variable load;

10. Avoid deformation and gaps caused by the outflow of genetic raw materials;

11. Improve the self-supporting capacity of the backfill soil behind the retaining wall, reduce the earth pressure of the retaining wall, save costs, increase the service life, and reduce maintenance costs;

12. Carrying out slope maintenance by integrating the construction method of shotcrete and concrete engineering can not only save 30%-50% of the project investment, but also reduce the construction period by more than double;

13. The one-way geogrid is added to the roadbed engineering and overall surface layer of the road, which can reduce the deflection value, reduce the asphalt pavement, and delay the gap for 3-9 times, which can reduce the thickness of the solid layer by 36%;

14. Applicable to all kinds of soil layers, no need for field sampling, saving working time;

15. The construction is simple and convenient, and the construction cost can be greatly reduced.

Two-way geogrid All in all, geotextiles and geogrids play a key role in engineering construction. They can not only extend the life of the project, strengthen the project, but also further meet the requirements of major projects. In the next 10 years or more, there will be more Infrastructure projects are to be constructed, and the demand for geotextiles and geogrids will also increase.
