- Q:What is a one-way plastic geogrid
- The plastic geogrid is a kind of polymer material with square or rectangular shape which is formed by stretching, and it can be used as two kinds of uniaxial tension and biaxial tension. The utility model is punched on the extruded polymer plate (raw material is polypropylene or high-density polyethylene), and then directionally stretched under the heating condition. The unidirectional stretching grid is only drawn along the length direction of the plate, and the bidirectional stretching grid is made by stretching the unidirectional stretching grid in the direction perpendicular to the length.
- Q:Evaluation criteria and technical disclosure of geogrid.. Know how to share. Thank you
- 2) according to the design of the location, along the road to the laying of the grid, laying the grille, should pay attention to the connection between the grid and straightening smooth. Grille of the longitudinal and transverse joints can use nylon or polyester rope sewn or U nail connection method between the grid as a whole, grid overlapping width not less than 20cm, in the direction of the stress intensity of the joint shall not be less than the design tensile strength of materials. The grid distortion, fold, overlap, is not conducive to play its role, thus laying by hands straightened, the grid is smooth and uniform, geogrid every 1.5-2.0m paved with hook nail fixed on the ground.
- Q:The difference between the overlap length and the overlapping width of the geotextile in reinforced embankment
- The installation of geotextiles is usually done by means of overlapping, stitching and welding. The width of the stitching and welding is generally 0.1M or more, and the overlap width is generally more than 0.2M.
- Q:What is geogrid, what is the role?
- Glass fiber geogrid is a way used to enhance, reinforcement, reinforcement of excellent geosynthetic materials of soft soil subgrade. And in the treatment of asphalt pavement reflection crack applications, has become the indispensable materials. The product is made of high strength alkali free glass fiber through international advanced knitting process made of mesh substrate. Semi rigid products by surface coating processing and made with warp and weft two-way high tensile strength and low elongation, and high temperature resistance, low temperature, aging resistance, corrosion resistance and other excellent properties, is widely used in the asphalt pavement, cement concrete pavement and subgrade reinforcement and railway roadbed, dam slope protection, airport runway, sand project.
- Q:Can geogrids be used in reinforcement of mechanically stabilized earth bridge piers?
- Yes, geogrids can be used in the reinforcement of mechanically stabilized earth bridge piers. Geogrids are commonly used in such applications to provide additional strength, stability, and load-bearing capacity to the soil, enhancing the performance and longevity of the bridge piers.
- Q:Are geogrids suitable for reinforcement of soft subgrades?
- Yes, geogrids are suitable for reinforcement of soft subgrades. Geogrids are commonly used in civil engineering projects to improve the stability and strength of weak soil or subgrade. They help distribute load and reduce settlement, preventing soil deformation and enhancing overall performance. Geogrids effectively reinforce soft subgrades by confining the soil particles and increasing their shear resistance, resulting in improved stability and reduced risks of failure.
- Q:Geocell of earthwork grid construction method
- Engineering application of geocell1, deal with half fill roadbedOn the ground of natural slope in 1:5 acts on the slope of embankment, embankment should be dug in steps, step width not less than 1M when the stage of building or rebuilding highway widening, convergence of old and new subgrade embankment slope, excavation step should be of high grade highway, the step width is 2M, the laying of geocell in each layer step on a horizontal plane, using geocell own facade side limit reinforcement effect, the problem of uneven subsidence of a better solution.2, sandy area roadbedSandy area on the low embankment subgrade, filling height is generally not less than 0.3M. due to the Low Subgrade Construction of sandy area and heavy bearing professional requirements, the geocell can play on the loose packing lateral confinement effect, with high stiffness and strength in the limited height of subgrade protection, to load large vehicle stress.3, the back embankment fillThe geocell reinforced abutment can achieve the purpose of better, geocell and fillers can generate enough friction, effectively reduce the roadbed and structures between uneven settlement, can effectively alleviate the "final abutment jump" disease of the early impact damage of bridge deck.
- Q:Fiberglass grille price?
- Fiberglass geogrid price is divided according to the model, fiberglass geogrid models are 30KN, 40KN, 50KN, 60KN, 70KN, and so on, the maximum can reach 200KN. Fiberglass geogrid models are as follows:
- Q:How do geogrids improve the stability of landfills?
- Geogrids improve the stability of landfills by providing reinforcement and support to the waste materials, preventing slope failure and maintaining the overall integrity of the landfill structure.
- Q:What are the long-term maintenance requirements for geogrid-reinforced structures?
- The long-term maintenance requirements for geogrid-reinforced structures typically involve periodic inspections to ensure the integrity of the structure and the geogrid. These inspections may include visual assessments, measurements, and testing to detect any signs of damage, settlement, or deterioration. Additionally, regular cleaning and removal of debris from the structure is necessary to prevent blockages or potential damage. Overall, proper maintenance and timely repairs are essential for the longevity and performance of geogrid-reinforced structures.
