Product Introduction:
Geotextile Cloth Bunnings are a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. Its raw materials are mostly high molecular weight polymers such as polypropylene, polyester, nylon, etc., which are processed through different processes to form fabric structures with certain thickness, porosity, and mechanical properties, which can adapt to various environmental and load conditions in civil engineering.
characteristic
1. Filtration: When water flows through geotextiles, their pores can block impurities such as soil particles, prevent soil erosion, and ensure normal water infiltration. For example, in the construction of dams in hydraulic engineering, geotextiles can filter the water flow on both sides of the dam to prevent soil erosion.
2. Drainage: The pores inside the geotextile form drainage channels, which can quickly drain the accumulated water inside the structure, reduce pore water pressure, and improve the stability of the structure. In highway construction, geotextile can be laid in the roadbed to drain accumulated water and prevent roadbed settlement.
3. Isolation: It can separate materials of different properties, prevent them from mixing with each other, and ensure that each material can exert its own performance. In railway construction, geotextile can isolate the crushed stones under the railway tracks from the roadbed soil, preventing crushed stones from entering the roadbed soil and affecting the stability of the railway tracks.
4. Reinforcement: Through its own high strength, it can enhance the bearing capacity and deformation resistance of the soil, and improve the mechanical properties of the soil. In the treatment of soft soil foundation, geotextile can be used as a reinforcement material to improve the bearing capacity of the foundation and reduce its settlement.
5. Protection: It can protect soil or other structures from erosion and damage caused by external factors. For example, in river regulation projects, geotextiles can be laid on river slopes to prevent water flow from scouring the slopes.
