Needle geotechnical cloth can be widely used in water conservancy, hydropower, roads, railways, ports, airports, sports venues, tunnels, coastal tidal flats, reclamation, environmental protection and other fields, playing the role of isolation, filtration, drainage, reinforcement, protection, closure and so on.
1. Isolation the building materials with different physical properties, so that the overall structure and function between two or more materials are not lost, do not mix, maintain the overall structure and function of the materials, and strengthen the load bearing capacity of the structure. 2. When the water flows from the fine material drawing layer into the coarse material drawing layer, use the good air permeability of the needle geotextile to make the water flow through, and effectively intercept particles, fine sand, small stone, etc., to maintain the stability of soil and soil engineering. 3. Needle geotextile is a good water guide material, it can form a introduction channel inside the soil, excluding excess liquid and gas inside the soil structure. 4. The soil tensile strength is used to enhance the deformation ability and increase the stability of the building structure to improve the soil quality. 5. Effectively will spread, transfer or decompose, to prevent the soil from being damaged by external force.
