It is composed of bidirectional reinforced strips combined through an innovative manufacturing process. Thanks to the product's surface, which has been embossed into a regular, coarse pattern, when laid over the compacted fill material, it effectively resists significant tensile stresses and generates substantial friction against the surrounding soil. This, in turn, collectively restrains shear deformation of the foundation soil, preventing lateral挤压 and uplift. Moreover, due to the high stiffness of the reinforced soil mat, it promotes efficient diffusion of the load from the upper foundation structure, distributing it more evenly across the underlying soft soil layers—thereby significantly enhancing the overall bearing capacity of the foundation. Additionally, the presence of the reinforced soil mat boosts the overall rigidity of the foundation within the compaction zone, making it easier to control and optimize ground deformation.

Additionally, the presence of the reinforced soil mat boosts the overall rigidity of the foundation within the compaction zone, making it easier to control and optimize ground deformation. High-strength geogrids are created by combining high-strength steel wires (or other fibers), which have undergone special treatment, with polyethylene (PE) or polypropylene (PP), along with additional additives. This mixture is then extruded to form a composite, high-tensile strip featuring a textured, rough surface. These individual strips can subsequently be woven or interleaved in both longitudinal and transverse directions at precise intervals. The intersection points are then welded together using a specialized, reinforced bonding technique—specifically, a fusion welding method—to produce the final high-strength geogrid structure.

Thanks to the product's surface, which has been embossed into a regular, coarse pattern, when laid over the compacted fill material, it effectively resists significant tensile stresses and generates substantial friction against the surrounding soil.

Additionally, the presence of the reinforced soil mat boosts the overall rigidity of the foundation within the compaction zone, making it easier to control and optimize ground deformation. It is a grid structure made of polypropylene as the base material, treated with antistatic and flame-retardant technologies, and then formed using a biaxial stretching method. Its performance characteristics are as follows:
1. Friction does not easily generate static electricity. In the environment of coal mine shafts, the average surface resistance of plastic mesh consistently remains below 1 x 10^9.2 ohms.
2. Exhibits excellent flame-retardant performance. In an open-flame environment, it melts but does not burn—indeed, if ignited, it will extinguish within 10 seconds after the flame is removed.
3. Strong corrosion resistance, preventing aging.
4. Easy to construct and transport: The plastic mesh is relatively flexible, preventing workers from being accidentally cut during construction. Additionally, it’s easy to roll, bundle, cut to size, and lightweight—making it convenient for underground transportation, carrying, and on-site installation.
5. Easy to wash coal with. This plastic mesh has a density between 0.89 and 0.91, which is lower than that of water. During the coal-washing process, the broken mesh strips float on the water, making them easy to rinse away.
6. The plastic mesh, after undergoing both compression and stretching processes, exhibits strong load-bearing capacity in both longitudinal and transverse directions. Its molecular structure is effectively realigned, resulting in a tensile strength that is 2 to 3 times greater than the material’s original strength before stretching. The interlocking "ribs" and "supports" formed during bidirectional stretching create a robust, interconnected network that efficiently distributes applied pressure outward through the nodes, significantly enhancing the overall compressive resistance of the mesh. This design also minimizes the risk of rib or support failure under stress. Moreover, because this plastic mesh is produced via bidirectional stretching rather than weaving, it demonstrates minimal mesh deformation over time and maintains consistently uniform mesh dimensions. As a result, it effectively prevents loose coal fragments from falling through, ensuring enhanced safety for underground workers as well as the smooth and uninterrupted operation of mine carts.
1. It enhances the stability of embankments, effectively preventing issues such as sliding, landslides, and settlement. Additionally, it ensures that the load applied to the upper structure is evenly distributed throughout the soil layers. In other words, when soft soil foundations are subjected to overlying loads that could potentially lead to shear failure, the geogrid acts as a barrier, inhibiting the formation of failure surfaces and thereby significantly improving the foundation's load-bearing capacity. Moreover, when the geogrid encounters concentrated stress, its high-modulus, bidirectional plastic geogrid from Qianjiang District, Chongqing, generates lateral forces upon deformation, which help redistribute and neutralize part of the applied load. This mechanism not only boosts the foundation's overall load-carrying capacity but also allows for a faster loading rate on the subgrade, ultimately shortening construction timelines.
2. You effectively enhance the foundation's load-bearing capacity. Since heavy machinery tends to sink into soft ground sections, it becomes difficult to properly compact the embankment fill. However, after installing a sand cushion layer combined with bidirectional plastic geogrids in Chongqing’s Qianjiang District, construction equipment like rollers can now safely operate on the surface. Typically, when building embankments on untreated soft soil foundations, varying degrees of "springy" behavior occur within certain fill heights, making it challenging to achieve proper compaction and resulting in poor surface smoothness. After laying the geogrids, though, their confining effect significantly improves the compaction process, ensuring a uniformly smooth and stable surface.

Additionally, the presence of the reinforced soil mat boosts the overall rigidity of the foundation within the compaction zone, making it easier to control and optimize ground deformation. While enhancing the bearing capacity and stability of the foundation, it also effectively mitigates uneven settlement, enabling a quicker reduction in differential settlement across the subgrade. The geogrid and gravel layers together form a composite cushion with significantly higher stiffness than the underlying soft soil, redistributing the loads applied from above. Additionally, their excellent permeability and drainage capabilities help balance the stress distribution within the foundation, accelerating the consolidation process of the soft soil under water pressure. This, in turn, promotes uniform settlement of the embankment, ensuring a smooth and level road surface.
4. When constructing embankments on a foundation that transitions from soft to hard, incorporating geogrids can more effectively ensure the safety of the embankment during construction and accelerate the process of achieving balanced settlement and stability. On such foundations, uneven settlement differences can lead to cracking or even instability in the subgrade. However, thanks to the load-distribution properties of the bidirectional plastic geogrids used in Chongqing’s Qianjiang District, the entire cross-section remains evenly supported, preventing these issues.
