The Steel Plastic Geogrid Must be Used for Reinforcing Embankments
Author:
Steel geogrid is used when handling the reinforced silt
Geogrid reinforcement of silt dykes:
When dealing with foundations, we generally use steel-plastic geogrids. We use longer roadbeds. We use less roadbeds to reinforce and extend service life. Especially in the desert area or the plateau of frozen soil.
Today we will look at the use of steel-plastic geogrid to strengthen the silt. Silt is more difficult to repair in many roadbeds and has a large water content. The gap is relatively large, featuring high compressibility, high sensitivity and low strength. We generally deal with sludge by dehydration, stabilization, drying, and soil addition. When using the silt foundation as a bank, we need to use steel plastic geogrid reinforcement. The volume of the cofferdam needs to bear a lot of pressure, but it has to be raised. It is obviously different from the way we usually strengthen it. However, we have investigated the use of steel-plastic geogrid for the seeding projects outside the New Year.
The plastic geogrid has a large friction and a small creep. Suitable for all types of environments, regardless of temperature, humidity and other aspects. It is important to increase the carrying capacity of the foundation.
The plastic geogrid is made of plastic material as a protective layer, supplemented by various additives to make it resistant to aging and oxidation. It can withstand the corrosion of harsh environments such as acid, alkali and salt. Plastic geogrid can meet various types of corrosion. The long-term engineering needs for more than 100 years, its superior performance and good dimensional stability are indispensable materials in civil engineering. Plastic geogrid is mainly used in soft soil foundation reinforcement, retaining wall and pavement anti-cracking engineering for roads, railways, bridges, approach roads, wharfs, revetments, dams, slag yards, etc.
The tensile force of the plastic geogrid is carried by the high-strength steel wire woven by warp and weft, which produces a very high tensile modulus under low strain capacity, and the longitudinal and transverse ribs cooperate to fully exert the interlocking effect of the grid on the soil. During the production process, the plastic surface is treated to suppress the rough pattern, which can enhance the roughness of the grating surface and improve the friction coefficient between the grid and the soil. Compared with the traditional grille, the plastic geogrid has the characteristics of high strength, strong bearing capacity, corrosion resistance, anti-aging, large friction coefficient, uniform hole, convenient construction and long service life. It is more suitable for deep sea operations and embankments. Reinforcement has fundamentally solved the technical problems of low strength, poor corrosion resistance and short service life caused by long-term erosion of seawater by other materials, and it can effectively avoid the crushing of the implement during the construction process. Construction damage caused by damage.
