Geotextile reinforcement method and construction requirements
Widely used in geotechnical engineering such as water conservancy, electric power, mines, highways and railways: filter materials for soil separation; drainage materials for beneficiation of mines and mines; drainage materials for foundations of high-rise buildings polyester geogrid manufacturers; anti-scouring materials for river dams and slope protection; 1. Reinforcement materials for airport runway foundations, reinforcement materials for road construction in swamp areas; frost and frost-resistant insulation materials; and anti-cracking materials for asphalt pavements.
Geotextile reinforcement method and construction requirements: Geotextile is used as a reinforcing material to reinforce the foundation. Its function is similar to flexible firewood. (The log is made of logs or bundled tipping materials, which is spread on the bottom of the embankment, so as to expand the foundation to disperse the load and maintain the stability of the embankment base.) In the embankment with high groundwater level and soft soil foundation high quality uniaxial plastic geogrid, padding earthwork is used The stiffness of the roadbed reinforced by cloth is favorable for drainage. In high-filled embankments, proper layering can be used for padding; padding geotextile on soft foundation can make the load distribution even.
Material: Geosynthetics should have the advantages of light weight, good overall continuity, high tensile strength, corrosion resistance, good anti-microbial erosion, and convenient construction. Non-woven uniaxial plastic geogrid for sale should have small pore diameter and good permeability. The texture is soft and can combine well with soil.
The width, quality, thickness, tensile strength, burst strength and permeability coefficient of the selected geosynthetics should meet the design requirements. Construction: Lay on the leveled under bearing layer according to the full width of the bottom of the embankment, straighten and smooth when flattening, close to the under bearing layer, no distortion, wrinkle, overlap. When paving on slopes fiberglass geogrid factory price, a certain degree of tightness should be maintained (U-shaped nails can be used to control).
When laying the geopolymer, sufficient anchor length should be left on each side of the embankment, folded back to cover the compacted packing surface. In order to ensure the integrity of the geosynthetics, when using the lap method to connect, the lap length should be 0.3 ~ 0.9m; when using the seam method, the bonding width is not less than 50mm, and the bonding strength is not lower than the geosynthesis The tensile strength of the material. In the field construction wholesale fiberglass geogrid, on the one hand, it should be noted that the geosynthetics must be repaired immediately when damaged, on the other hand, the upper and lower joints should be staggered alternately, and the staggered length should not be less than 0.5m. During the stacking and laying of geosynthetic materials, try to avoid prolonged exposure and exposure to avoid performance degradation. The quality of the laying should meet the specifications.
In soft soil and swamp areas, where the foundation is wet and soft and the groundwater level is high, treatment with cushions and covering geotextiles will receive better results. In construction, the geotextile is paved with high quality gravel geocell on the base and folded along the slope, so as to cover the embankment paving, which can not only improve the rigidity of the base, but also help drainage, and redistribution of foundation stress to increase the stability of the roadbed.
