Shandong Zheda Plastic Geogrid Steel Plastic Grating Supply Geogrid Manufacturer

One-way plastic geogrid is a kind of high molecular polymer as the main raw material, adding certain anti- Ultraviolet anti-aging additive is a high-strength geotechnical material made by uniaxial stretching to reorient and arrange the originally scattered chain molecules into a linear state. It is extruded and pressed into a thin plate, punched into a regular mesh, and then stretched longitudinally. In this process, the polymer is brought into a directional linear state and forms an oblong network-like overall structure with uniformly distributed nodes and high strength. This kind of structure has very high tensile strength and tensile modulus. The tensile strength is close to the level of low carbon steel, which is much better than traditional or existing reinforcement materials. In particular, this kind of product of this company has more advantages. High early elongation in tensile strength and tensile modulus exceeding international levels. It provides the soil with an ideal interlocking system for force bearing and diffusion. This product has high tensile strength and is adaptable to various soils. It is currently a widely used reinforcement material.

Geogrids are very commonly used for foundation reinforcement in highways and railways. In current design specifications, the tensile strength of geogrids is generally used as the mechanical index of design requirements. In fact, there are many factors that affect the reinforcement effect. Many experiments have been conducted in China to study the impact of different reinforcement layers, cushion thickness, etc. on reinforcement. However, due to the mesh shape of the grille due to the production process, There are few domestic studies on the differences in reinforcement effects caused by different physical properties such as hole size, rib shape, etc. The bearing capacity and deformation performance of different types of geogrid reinforced cushions were studied through in-situ shallow load plate tests. Tests have shown that geogrids with different physical and mechanical properties of different raw materials and different production processes have different bearing capacity and deformation properties of the reinforced cushions, as well as different stress diffusion effects. The high strength of the grid cannot enhance the reinforcement effect. .

One-way plastic geogrid is used to reinforce weak foundations. One-way plastic geogrids can quickly increase the bearing capacity of the foundation, control the development of settlement, and have a negative impact on the road base. The side limit function can effectively distribute the load to a wider base layer, thereby reducing the thickness of the base layer, lowering the project cost, shortening the construction period, and extending the service life. Unidirectional plastic geogrid is used to reinforce asphalt or cement pavement. Geogrid is laid at the bottom of asphalt or cement pavement, which can reduce the depth of ruts and extend the anti-fatigue life of the pavement. It can also reduce the thickness of asphalt or cement pavement to save costs. Unidirectional plastic geogrids are used to reinforce embankment dams and retaining walls. The filling of traditional embankments, especially high embankments, often requires overfilling and the edge of the shoulder is not easy to compact, which leads to later rainwater infiltration of the slope and collapse and instability. phenomenon occurs from time to time. At the same time, a gentle slope is required, which occupies a large area. The retaining wall also has the same problem. Using geogrids to reinforce the embankment slope or retaining wall can reduce the area occupied by half. Extend service life and reduce cost. One-way plastic geogrids are used to reinforce river and sea embankments and can be made into gabions, which can be used together with the grid to prevent the embankments from being washed away by seawater and causing collapse. The gabions are permeable and can slow down the impact of waves, extend the life of the embankments, and save manpower and material resources. , shorten the construction period. One-way plastic geogrid is used to treat landfills. Geogrids are used in combination with other soil synthetic materials to treat landfills. They can effectively solve problems such as gas emissions derived from uneven settlement of foundations, and can maximize the efficiency of landfills. storage capacity. Special purpose low temperature resistance of unidirectional plastic geogrid.
