Where is geogrid used and where is geogrid used?

Road reinforcement... Prevent road subgrade subsidence.

It is mainly used for the protection of coal mine underground mining, and can be used as a supporting material for various roadways such as anchor roadway, support roadway, anchor spray roadway, etc. When used for false tops, sell more than double layers of combined use.

Geogrid is a major geosynthetic, which has unique properties and efficacy compared to other geosynthetics. It is often used as a reinforcement material for reinforced soil structure or a reinforcement material for composite materials.

Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, fiberglass geogrids and polyester warp knitted polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid with a certain height made of polypropylene, polyvinyl chloride and other polymer polymers by thermoplastic or molding, and when used as a civil engineering, it is called a geogrid.

A major geosynthetic, compared with other geosynthetics, it has unique properties and efficacy, and is often used as a reinforcement of reinforced soil structure or reinforcement of composite materials.

Geogrids are used to prevent cracks in culverts. Geogrids are used to strengthen soil slopes and prevent soil erosion. Geogrid is used to reduce the thickness of the cushion and save costs. Geogrid is used to support the stable green environment of slope grass planting mats.

It is suitable for roadbed reinforcement pavement enhancement of various highways, railways and airports. It is suitable for permanent load-bearing foundation enhancement such as large parking lots and dock freight yards. It is suitable for slope protection of railways and highways.

Applicable culvert enhancements. It is suitable for the secondary enhancement of the soil slope after the reinforcement of the unidirectional tensile geogrid, further enhancing the soil slope and preventing soil erosion. Reinforcement of mines and tunnels.

Geogrid is a general term for geotechnical materials, which are divided into glass fiber geogrids, two-way plastic geogrids, unidirectional plastic geogrids, steel-plastic composite geogrids, fine-knitted polyester geogrids and other products according to different materials.

Bi-directional plastic geogrid.

Unidirectional stretching of geogrids for soft foundation reinforcement: Geogrids can quickly increase the bearing capacity of foundations.

To control the development of settlement, its lateral restriction effect on the road base can effectively reduce the load.

Disperse to a wider subbase, thereby reducing the thickness of the base, reducing the project cost, shortening the construction period and service life. One-way geogrids are used to reinforce asphalt or cement pavement: geogrids are laid at the bottom of asphalt or cement pavement, which can reduce rutting.

depth, extend the fatigue life of the pavement, reduce the thickness of the asphalt or cement pavement to save costs. It is used to reinforce embankments.

Slopes and retaining walls.

Traditional embankments, especially high embankments, are often overfilled with shoulders.

The edge is not easy to compact, resulting in the slope being soaked by rainwater in the later stage, and the phenomenon of collapse and instability occurs from time to time. At the same time, it needs a gentle slope and a large footprint, and the retaining wall has the same problem. Reinforcing embankment slopes or retaining walls with geogrids can reduce the floor space by half, extend service life, and reduce costs by 20-50%.

What is Geog-Geshan? Through the following introduction, it can be known that it is an excellent geosynthetic, often used in the field of building materials processing, such as asphalt pavement operation and construction process can see the figure of the product, in addition, in the process of selecting geotechnical Geshan per mu, the comparison and analysis of the material that should be referred to is also more complex, qualified geotechnical Geshan low cold resistance, anti-aging, excellent corrosion resistance, you can refer to this standard to start, I believe that this can achieve satisfactory results.

1. What is geogrid?

Geogrid is an excellent geosynthetic material used for pavement reinforcement, old road reinforcement, reinforcement of roadbed and soft soil foundation. In the application of asphalt pavement reflection cracks, it has become an irreplaceable material. The product is a semi-rigid product made of high-strength and alkali-free mesh substrate through the international advanced warp knitting process, and made by surface coating.

It has high tensile strength and low elongation in both directions of warp and weft, and has excellent properties such as high temperature resistance, low cold resistance, aging resistance, corrosion resistance, etc., and is widely used in asphalt pavement, cement pavement and roadbed enhancement and railway subgrade, embankment slope protection, airport runway, sand control and other engineering projects.

Glass fiber grid is a high-quality enhanced alkali-free glass fiber yarn, the use of foreign advanced warp knitting machine woven into the base material, the use of warp knitting directional structure, make full use of the strength of the yarn in the fabric, improve its mechanical properties, so that it has good tensile strength, tear strength and creep resistance, and after high-quality modified asphalt coating treatment into a flat network material. It follows the principle of similarity compatibility, focuses on its composite properties with asphalt mixture, and fully protects the glass fiber substrate, which greatly improves the wear resistance and shear resistance of the substrate, so as to enhance the road surface with a hectare and resist the occurrence of road diseases such as cracks and ruts, and ends the problem that the asphalt pavement is difficult to strengthen.

2. What is the function?

1.Old asphalt concrete pavement, reinforced to strengthen the asphalt surface layer, disease control.

2.Cement concrete pavement is reconstructed with composite pavement to inhibit reflection cracks caused by plate shrinkage.

3.Road expansion and reconstruction project to prevent and control cracks caused by the junction of the old and the new and uneven settlement.

4.The soft soil foundation reinforcement treatment is conducive to the rapid annihilation and water consolidation of the soft soil, effectively inhibits the settlement, uniformly distributes the stress, and enhances the overall strength of the subgrade.

5.The semi-rigid base of the new road produces shrinkage cracks, and the reinforcement is strengthened to prevent the pavement cracks caused by the reflection of foundation cracks.

The above is highly recommended is about the purchase of geotechnical Geshan in many aspects, from which we can know that the product is widely used in asphalt pavement cement pavement, or the enhancement of the roadbed and the construction and operation of the railway subgrade, and has high temperature resistance, low cold resistance, aging resistance, corrosion resistance of the excellent low, further can know that the material of the product is also more complex, the later processing operation technology is also a lot, we should refer to the mechanical properties and performance effect of the factors to start, in order to achieve a satisfactory later purpose.
