Steel Geogrid also called GSZ geogrid: the steel plastic reinforced composite geogrid is compounded by a new process of steel plastic reinforced strip, while the steel plastic lacing strip is extruded by heating steel wire and plastic polypropylene particles into a strip shape, and the steel wire of the longitudinal rib of the steel plastic geogrid is woven into a mesh in longitude and latitude, and the outer wrapping layer is formed once, the steel wire and the outer wrapping layer can be harmonious, and the breaking elongation rate is very low. The * * * force bearing unit of steel plastic composite geogrid is steel wire, with low creep and elongation meeting the requirements. Therefore, the size, model and quantity of steel wire is the key to determine the quality of steel plastic geogrid key 。
**The difference between steel plastic grille and * * * steel plastic grille lies in the thickness of the steel wire used, * * generally 0.6 and 0.7 mm steel wires, and the same number of steel wire plastic lacing straps. * * * products are generally made of fine steel plastic 0.55 or 0.5 mm steel wires. 0.5 mm and 0.6 mm 0.7 mm steel wires are indistinguishable with the naked eye, and can only be measured with an instrument. The different tensile forces in the steel plastic geogrid mainly depend on the tensile strength of the steel wire. If it is 0.7mm steel wire, ten steel wires in one steel plastic belt are 7KN steel plastic belt. If you want a 70KN grille, you need ten belts within one meter. Another customer asked, "How many steel wires can make the tensile force of the steel plastic geogrid reach 100KN?" Such questions are not about how many steel wires. Generally speaking, it depends on how thick steel wires are used and the number of steel wires. Then it is calculated that if the steel wires are thick, there are fewer steel wires.
You are kindly reminded that the tensile force of the steel plastic geogrid is determined by the size and quantity of the steel wire. You must repeatedly determine the parameters and indicators of the steel wire in the procurement process. Don't blindly pursue * * *, be deceived by some illegal traders, and purchase unqualified products, which will affect the quality of the whole project
With the continuous expansion of the market demand for geotechnical materials, the production enterprises of geogrid have sprung up like mushrooms. The fierce competition has led to the emergence of various quality levels and prices.
***First of all, we should understand the price of steel plastic geogrid, and distinguish it according to the material and strength of different geogrids. Naturally, the same is true of steel plastic geogrid. The higher the strength large The more expensive the price is, the products that have not passed the factory test will not leave the factory or will leave the factory after the model is reduced. Our company has been strict With the "product quality" as the core, the responsibility should be assigned to each person. Each product of * * * should be delivered in strict accordance with the production standards and customer needs.
Secondly, the steel plastic geogrid is a new building material introduced from abroad, and it is also the product of the vigorous development of the geogrid market. Steel plastic geogrid is widely used in various subgrade, pavement and civil engineering with strength requirements. The quality of steel plastic geogrid determines the project quality. The quality of steel plastic geogrid is only one aspect, like that used in construction filler The quality of geogrid will also affect the function of geogrid. As the steel plastic geogrid is a flexible material, it can withstand the tensile stress of * * *. It is arranged in the tensile deformation zone of the soil mass, and the tensile stress of the soil is transmitted to the steel plastic geogrid, so that the reinforcement becomes Anti Pull members. In the rolling process, when the reinforced soil is under load, the materials above and below the grid can be combined by wrapping and embedding the granular materials in the grid mesh. Make the base course surface form a whole and strong compact body with interlocking up and down. The friction resistance between the steel plastic geogrid and the soil restricts the deformation of the soil, and has a mutual embedding effect with the soil, which greatly improves the rise The ability of subgrade soil to bear shear stress has changed the settlement condition on the cross section of normal embankment. The settlement on the cross section tends to be uniform, which can reduce the differential settlement at the junction of new and old subgrades and prevent longitudinal and transverse cracks in the pavement at the junction of new and old subgrades.
