Answer:

The construction requirements of geosynthetics are as follows. First, the definition and function features: reinforcement, protection, filtration, drainage and insulation. Second, types and purposes: geotextile net, geogrid, geotextile bags, geotextile, geotextile composite drainage material, fiberglass mesh and geotextile mat. Purposes: 1, reinforced embankments, 2 reinforced embankment fill 3, filtration and drainage, 4 embankment protection. Third, the construction requirements of geosynthetics (methods and requirements of using the geotextile to reinforce the foundation) (a) the method of using geotextile to reinforce the foundation: When using the lapping method, lap length is preferably to be 0.3 to 0.9m. When the splicing method is used, the bonding width should be not less than 50mm and the bonding strength should be not less than the tensile strength of the material. The upper and lower seams should be staggered and the staggered length should be not less than 0.5m. (b) The main requirements for the method of using geotextile to deal with the base are explained as above.
1. In terms of reinforcement, the geogrid should be considered first. 2. The geosynthetics should not be laid directly on the surface of the original foundation. 3. When laying the geotextile material, it should be perpendicular to the axis of the road.
