Construction requirements for the method of reinforcing the foundation with geotextile
Reinforce the foundation with geotextile as a reinforcement material, and its effect is similar to that of a flexible firewood row. (Use logs or bundled tip materials to make firewood rafts, spread them on the bottom of the embankment, and then expand the foundation's loose load effect and maintain the stability of the embankment base.) In the embankment with high groundwater level and soft soil foundation, use cushion geotechnical work. The cloth strengthens the rigidity of the roadbed and facilitates drainage.
In the high-filled embankment, it can be separated by layers; the geotextile on the soft foundation can be used to spread the load evenly. Data: The geotechnical composition data should have light weight, good overall continuity, high tensile strength, corrosion resistance, Good anti-microbial erosion, convenient construction and other advantages, non-woven geofiber should have the functions of small pore diameter, good permeability, soft texture, and good combination with soil.
The width, quality, thickness, tensile strength, bursting strength and permeability coefficient of the selected geotextile materials should meet the planning requirements. Construction: Lay the leveled submerged layer according to the width and full section of the bottom of the embankment. The spreading is usually straightened and smooth, and it is close to the submerged layer without distortion, wrinkles, or stacking. When paving on a slope, the tightness should be maintained (it can be manipulated with staples).
When laying geopolymers, a sufficient anchorage length should be left on each side of the embankment, and folded back to cover the compacted filling surface. For the integrity of the geotechnical composition materials, when the lap joint method is selected, the lap length should be 0.3~0.9m; when the seam joint method is selected, the bonding width shall not be less than 50mm, and the bonding strength shall not be lower than the tensile strength of the geotechnical composition materials. strength.
